Planetary Geography of Eldarûn · The World of Eldarûn

This entry establishes the planetary-scale geography of Eldarûn.

It does not attempt to name every continent, sea, mountain range, river, kingdom, island, or settlement.

Those subjects belong to later geographic codices and the master cartographic record.

Instead, this doctrine establishes the physical framework into which all later geography must fit.

Its central principle is:

Eldarûn is a complete Earth-comparable planetary world whose geography is governed first by coherent natural processes and then modified only where specific canon establishes supernatural influence.

Continents have geological histories.

Mountains belong to mountain systems.

Rivers belong to watersheds.

Deserts require climatic causes.

Islands arise through understandable geological processes.

Coastlines affect settlement, trade, weather, and culture.

Distance matters.

Terrain matters.

Oceans separate peoples until ships, magic, politics, or necessity overcome them.

The map of Eldarûn must therefore function as geography before it functions as decoration.

1. Planetary Form and Scale

Eldarûn is a roughly spherical terrestrial planet.

More precisely, like other rotating planetary bodies, it is an oblate spheroid: slightly wider around its equatorial region than from pole to pole.

Eldarûn's physical planetary chassis is intentionally Earth-equivalent.

This is no longer merely a convenient comparison.

It is a hard astronomical dependency created by the established orbital architecture of Seryn and the three-moon celestial system.

The controlling planetary values are approximately:

mean planetary radius — 6,371 kilometers
mean planetary diameter — 12,742 kilometers
planetary mass — 5.97 × 10²⁴ kilograms
mean Surface gravity — 1 g, approximately 9.81 m/s²
equatorial circumference — approximately 40,000 kilometers
mean solar day — 24 hours
sidereal rotation period — approximately 23 hours, 56 minutes, 4 seconds
axial tilt / obliquity — approximately 23.44 degrees
tropical or seasonal year — approximately 365.2422 days
sidereal year — approximately 365.2564 days

These values create a familiar physical planetary environment.

They support:

Earth-comparable gravity
familiar bodily movement
ordinary atmospheric scale
familiar day-night rhythm
recognizable seasonal change
familiar latitude-dependent climate belts
familiar oceanic and geological scales
and the fixed lunar architecture established in Celestial Structure of Eldarûn

Eldarûn receives broadly Earth-comparable average solar energy at its Surface.

The sun is therefore sufficient to sustain the familiar range of:

oceans
ice
temperate environments
tropical environments
deserts
forests
grasslands
and other ordinary planetary biomes

established elsewhere in the World Bible.

1.1 Axial Tilt and Seasons

Eldarûn's rotational axis is tilted approximately:

23.44 degrees

relative to the plane of its orbit around the sun.

This tilt provides the primary astronomical cause of ordinary seasons.

As Eldarûn travels around the sun:

one hemisphere receives more direct sunlight while the other receives less
day length changes with season
solar elevation changes
solstices and equinoxes occur
northern and southern seasonal cycles oppose one another

Latitude therefore has physical meaning.

A region's placement north or south of the equator affects:

temperature tendency
day length
seasonality
solar angle
polar-light conditions

although local geography, altitude, winds, and ocean currents can modify those expectations substantially.

1.2 Planetary-Celestial Dependency

Seryn's established orbital architecture is calculated against an Earth-equivalent planetary gravitational system.

Its:

~384,400-kilometer mean distance
~27.32166-day sidereal orbit
~29.53059-day synodic phase cycle
eclipse architecture
and Grand Syzygy recurrence

depend upon Eldarûn remaining compatible with the physical chassis established here.

Therefore, Eldarûn cannot later be made:

substantially larger
substantially smaller
substantially more massive
substantially less massive
or radically different in solar-year duration

without formally reopening the celestial model.

Likewise, a later alteration to Seryn's fixed orbital mechanics would require reconsideration of the planetary assumptions established here.

The two codices are mathematically coupled.

This relationship is a Hard Canon Lock.

2. Land and Water

The majority of Eldarûn's Surface is covered by water.

Its land-to-ocean balance is broadly Earth-comparable.

The exact final percentage is not yet required, but the intended range is approximately:

two-thirds to three-quarters ocean

with the remaining Surface divided among:

major continents
smaller continental masses
archipelagos
large islands
volcanic island chains
continental-shelf islands
polar islands
isolated oceanic islands

This ensures that oceans function as genuine geographic barriers.

A voyage between major continents is not equivalent to crossing a lake.

Ocean travel creates:

distance
isolation
maritime cultures
naval power
weather exposure
trade bottlenecks
exploration
migration barriers
distinctive island ecologies

The seas of Eldarûn must be large enough to matter.

3. Major Continental Architecture

Eldarûn possesses:

seven major continental-scale landmasses

This number is fixed.

Their complete final names, silhouettes, exact positions, and internal geography are not yet all fixed.

The seven-continent structure presently consists of:

1. The Primary Continent — the principal shared continental theater of most currently developed Surface civilizations.

2. The Aeshkar-Dominant Continent — the principal continental homeland of the Dominion of Aeshkar.

3. The Ferathi-Majority Continent — a major Ferathi continental homeland positioned within the wider maritime sphere between the Primary Continent and the Aeshkari world.

4–6. Three additional major nonpolar continents — intentionally retained for future geographic, ecological, historical, and civilizational development.

7. The Southern Polar Continent — a major continental landmass occupying the southern polar system.

The ancestral Tazhuran Archipelago is not one of the seven continents. It is a major oceanic archipelago centered upon one dominant great island and surrounded by substantial satellite islands, lesser islands, reefs, and volcanic systems.

Additional microcontinents, large islands, island arcs, volcanic chains, continental fragments, and polar islands may exist without changing the fixed seven-continent count.

The master map may determine what the seven continents look like.

It may not reduce or expand the number of major continental-scale landmasses without formally reopening this doctrine.

4. The Primary Continental Mass

The largest currently story-relevant continental landmass is the primary center of known Surface civilization.

Its final proper continental name remains to be established through cartography.

Until then, Primary Continent is an authorial geographic designation rather than an in-world proper noun.

This continent contains the principal homelands, kingdoms, regions, and mixed civilizations of most currently established peoples.

These include major populations of:

Valenkind
Elven-kind
Dwarven-kind
Orc-kind
common Troll-kind
Infernari
Lûmvari-associated territories
and many mixed settlements

This does not mean every member of those peoples lives upon this continent.

Migration, trade, colonization, exile, conquest, maritime settlement, and ancient population movement have spread peoples beyond their ancestral regions.

The Primary Continent is simply the principal shared civilizational landmass.

4.1 Geographic Character

The Primary Continent must be geographically large enough to support:

northern fjord country
tundra and subarctic lands
temperate forests
major mountain chains
highland basins
fertile river valleys
broad grasslands
red-soil plains
arid interiors
deserts
Mediterranean-like or warm-temperate regions
swamps and wetlands
coastal plains
large lakes
inland seas or major enclosed waters if later desired
old forests
World Tree regions
ley-scarred territories
and heavily settled agricultural heartlands

This ecological diversity must arise primarily from:

latitude
altitude
ocean proximity
rain-shadow effects
prevailing winds
mountain systems
watershed structure
and geological history

Magic may create local exceptions.

It must not be used as the default explanation for continental climate diversity.

5. Northern Primary Continent

The far northern and northward-facing regions of the Primary Continent support the cold-country traditions already associated with the Veydran.

5.1 The Stormfjords

The Stormfjords occupy northern Eldarûn.

They are a region of:

deeply cut coastal inlets
glacial valleys
steep cliffs
cold seas
mountain-backed coastlines
storm exposure
rocky islands
snow-fed rivers
seasonal ice
narrow agricultural pockets

The Fjord Veydran, sometimes described as Stone-Storm clans, are strongly associated with these northern lands.

Their geography should evoke the functional realities of:

Norwegian fjord country
Icelandic volcanic coasts
North Atlantic storm environments
high-latitude mountain shores

without reproducing any one Earth coastline.

5.2 Relationship to the Redmark

The Stormfjords lie north of the principal Redmark Plains.

This north-south relationship is a geographic hard lock.

The Fjord Veydran therefore inhabit colder and more maritime territory than the Plains Veydran.

Travel southward from the Stormfjords should gradually move through:

colder uplands
transitional highland country
open interior regions
and eventually the Redmark landscape

rather than teleporting abruptly from glacial coast to warm grassland.

6. The Redmark Plains

The Redmark Plains are one of the major interior grassland systems of the Primary Continent.

They are the principal homeland of the Plains Veydran and the Redmark herd-clans.

Their defining visual identity is:

broad red-toned grassland beneath enormous open sky

The precise biological and geological cause of the red coloration will be established in later biome and geology codices.

Possible natural contributors may include:

iron-rich soil
red-tinted grasses
seasonal pigment changes
mineral dust
particular soil microbiology

The final explanation should remain predominantly natural unless later canon establishes a ley influence.

The Redmark should be expansive enough to support:

large migrating herds
mobile clans
long-distance visibility
seasonal storm fronts
horse culture
caravan movement
open-country warfare
river corridors
dry and wet seasonal variation

The Redmark is not a small meadow outside a city.

It is a continental-scale plains region.

7. The Human Geographic Belt

The Primary Continent also contains the principal Valenkind homeland regions already established in canon.

These include:

Their exact placement against one another remains subject to the master map except where explicit relationships have already been established.

7.1 Dawnlands

The Dawnlands represent broad settled human country associated strongly with Valen civilization.

They should support:

agriculture
roads
villages
market towns
river systems
mixed woodland
major cities
politically fragmented but heavily inhabited territory

The Dawnlands should function as one of the major connective regions of the Primary Continent.

7.2 Heartforge Vales

The Heartforge Vales are associated with the Valthen.

Their geography should favor:

fortified valleys
defensible passes
upland agricultural basins
stone-rich terrain
mountain foothills
river-fed valleys
civic centers protected by natural topography

They should logically border or interact with significant mountain systems.

7.3 Sands of Serath

The Sands of Serath are associated with the Serathi.

They occupy a major dryland and trade region rather than an inexplicable magical sand patch.

Their existence should ultimately be supported by:

continental interior position
subtropical atmospheric circulation
rain shadow
mountain barriers
cold-current influence
or some combination of those processes

The region may include more than dune sea.

A realistic dryland system can contain:

rocky desert
gravel plains
salt flats
dry mountains
seasonal riverbeds
oasis systems
scrub country
coastal desert
dune fields

Serathi mobility and trade culture should arise partly from this geographic reality.

8. The Xer’Arun Waste

The Xer’Arun Waste is a major arid or semi-arid interior region of the Primary Continent.

Its narrative function is comparable to a great interior wilderness or desert barrier.

It must nevertheless remain geographically original to Eldarûn.

The Xer’Arun Waste should not simply duplicate the Sands of Serath.

The two regions may differ in:

latitude
altitude
geological origin
rainfall
vegetation
population
travel danger
magical history

A strong final arrangement would make the Xer’Arun Waste a great continental interior basin or rain-shadow region separated from the culturally developed Serathi drylands.

It may contain:

barren uplands
wind-carved stone
salt basins
dry steppe
dune seas
ancient lakebeds
isolated mesas
seasonal rivers
buried ruins
dangerous caravan corridors

The exact position and environmental history of the Waste remains dependent upon the master continental map.

9. Known Story Geography

Existing manuscript geography is binding cartographic evidence.

The final master map must preserve established:

route sequence
direction of travel
relative placement
travel time
travel distance
terrain transition
access route
and transportation mode

where those relationships have already been canonized.

The purpose of the master map is to reconcile established story geography into one coherent physical world.

Established story geography should not be casually rewritten merely because another coastline or road arrangement appears visually cleaner.

9.1 Durnhollow-to-Branloch Route Spine

The established early journey follows:

Durnhollow → Evermark → Yandir → Trifang → Branloch

This order is fixed.

The caravan exits Durnhollow north through the outer approaches before the road bends west into lower and more open country.

The established timing sequence is:

Durnhollow → Evermark — arrival on day 7
Evermark → Yandir — 6 additional days; Yandir on day 13
Yandir → Trifang — 4 additional days; Trifang on day 17
Trifang → Branloch — south / southwest along the Trifang Trail; Branloch on approximately day 26 overall

Evermark and Yandir function as established waystations along the Durnhollow-to-Branloch line.

Trifang is the final major route settlement before Branloch.

The older erroneous concept of traveling east from Trifang toward Branloch is not canon.

The road system and eventual map must preserve both the sequence and the cumulative travel scale of this route.

9.2 Branloch Local Geography

Branloch lies beyond Trifang along the southern route.

The settlement sits in lower country associated with rolling terrain and nearby mountain approaches.

The farmstead associated with Deran lies:

west of Branloch

The principal mountain country associated with Thunderdelve lies:

east of Branloch

within the Bladewind mountain system.

This west-east relationship is a local cartographic constraint.

Therefore, a final Branloch-area map must preserve:

Deran farmstead → Branloch → eastern mountain country / Thunderdelve

as distinct geographic zones.

9.3 Branloch-to-Roaringwater Route

After the Branloch and Thunderdelve events, the established westward/long-distance road sequence is:

Branloch → Trifang → Westcross → Bellard → Roaringwater

The party travels this stage by a dedicated carriage rather than remaining with the original caravan.

The established segment timing is:

Branloch → Trifang — approximately 5 days
Trifang → Westcross — approximately 4 days
Westcross → Bellard — approximately 3–4 days
Bellard → Roaringwater — approximately 24–26 days

The manuscript therefore places the complete Branloch-to-Roaringwater movement at approximately:

38 days

with minor variation possible according to inclusive counting, camp timing, and departure hour.

The road system and continental map must contain enough physical distance to support this travel duration.

9.4 Roaringwater-to-Lorchel

The established route continues:

Roaringwater → Lorchel

Travel time by carriage is approximately:

5–6 days

Lorchel functions as the transition settlement between the long-distance road network and the party's approach to Daybreak Pass.

The carriage, horses, and associated road gear are secured or left at Lorchel before the party proceeds into the mountain sequence.

9.5 Lorchel, Daybreak Pass, and Dawnwatch

The established route continues:

Lorchel → Daybreak Pass → Dawnwatch Hold

The party undertakes this portion on foot.

This does not mean Daybreak Pass is universally impassable to wagons.

The principal Daybreak road is capable of supporting:

mules
wagons
wagon ruts
and ordinary overland traffic where conditions permit

The party's decision to continue on foot is therefore a narrative and logistical choice rather than evidence that no wheeled road crosses the pass.

Dawnwatch lies within the mountain-country system associated with:

Daybreak Pass
the Ashfang Region
and the Ashfang Mountains

The names Grey Peak and Greypeak Mountains are not current Eldarûnian geographic names for this region.

The controlling names are:

Ashfang Region

and:

Ashfang Mountains

9.6 Dawnwatch-to-Elarisel Route

After the Dawnwatch sequence, the party exits through the established hidden route.

The broad movement is:

Dawnwatch hidden exit → skirt Parthal → Elarisel

The route does not require the party to enter Parthal before reaching Elarisel.

The manuscript places the party roughly two days from the Parthal vicinity after the hidden exit, followed by approximately nine to ten additional days toward Elarisel under the current narrative reconstruction.

This segment includes the failed wardstone sequence and the approach to Elarisel.

9.7 Elarisel Return Route

The established return movement is:

Elarisel → Whispering Vale → Parthal → main Daybreak Pass → Lorchel → Grimvale → Roaringwater

Parthal is an actual stop on this return movement.

The party does not revisit Dawnwatch Hold during the return crossing.

The main Daybreak road provides the return passage through the mountain system.

The Lorchel → Grimvale → Roaringwater segment occupies approximately six days in the current return text.

This distinction is fixed because older working versions incorrectly routed the party back through Dawnwatch itself.

9.8 Eldergreen and the Allfather Oak

The later route connects Roaringwater with:

Eldergreen
the Allfather Oak
and the wider forest-road system

The Allfather Oak is a major geographic and ley-significant anchor within Eldergreen.

The established walking distance between the Allfather Oak and Roaringwater is approximately:

210 miles

At ordinary sustained overland pace, this represents roughly:

eight days on foot

under the travel assumptions already used in the narrative.

9.9 Roaringwater-to-Myth Celador

Roaringwater later functions as the transition point from prolonged foot travel back to mounted travel.

Horses are purchased or otherwise secured at Roaringwater before the eastward journey toward Myth Celador.

The established authorial route length from:

Roaringwater → Myth Celador

is approximately:

1,096 miles

The final master map must preserve a continental scale capable of supporting this long-distance journey.

The exact road shape may bend around:

mountains
rivers
forests
settlements
and political territory

so straight-line map distance should not be assumed to equal traveled road distance.

9.10 Geographic Constraint Doctrine

The routes above are not the complete geography of Eldarûn.

They are the current hard cartographic skeleton extracted from established story movement.

Future cartography may determine:

exact latitude
exact longitude
coastline relationship
watershed
local road curvature
surrounding political borders

but it may not casually contradict the established:

route order
major direction
travel duration
local east-west relationship
terrain transition
or transport mode

recorded here.

For cartographic reconstruction, the Geography Master Ledger and its current Geographic Compendium are the controlling working authorities for numeric source controls, source identity, point placement, route geometry, and cartographic closure state wherever older geographic prose conflicts with current World Bible or manuscript locks.

10. The Aeshkari Continental Mass

The Aeshkar are native to Eldarûn.

They do not come from another plane, demonic dimension, or outside realm.

Their principal homeland lies upon a separate major continent from the Primary Continent.

This landmass is the heart of the:

Dominion of Aeshkar

The final proper continental name remains to be established.

10.1 Continental Separation

The Aeshkari continent is separated from the Primary Continent by substantial ocean.

The Ferathi-majority continent occupies the wider maritime sphere between the Primary and Aeshkari continental worlds rather than lying isolated at the far edge of the globe.

Its broad authorial placement is central to south-central within that intercontinental relationship and is biased closer to the Aeshkari continent than to an exact midpoint.

This does not create a land bridge or trivial crossing. Substantial ocean separates all three continental systems.

The Primary-to-Ferathi crossing is the more substantial of the two major crossings, while the Ferathi-to-Aeshkar crossing is somewhat narrower but remains a major maritime frontier.

This spacing is great enough to produce independent historical development, distinct ecology, naval strategy, overseas campaigns, long-distance diplomacy, maritime trade, and cultural separation, but not so great that the continental worlds are effectively unreachable.

Aeshkar, Ferathi, and peoples of the Primary Continent therefore possess enough historical interaction for warfare, diplomacy, trade, raiding, migration, espionage, and political rivalry to remain physically plausible.

10.2 Aeshkari Geographic Character

The Dominion's established homeland includes:

scarlands
fortress-cities
crater basins
basalt provinces
border principalities
war-scarred territories

These environments should arise from a combination of:

volcanic geology
tectonic activity
ancient impacts or catastrophic events where established
historical warfare
Blightfire damage
ordinary erosion
long settlement history

The Aeshkari continent must not be reduced to one endless volcanic hellscape.

It is a true continent.

Therefore it also contains ordinary:

river systems
coastlines
agricultural zones
forests
grasslands
mountains
wetlands
fisheries
habitable plains

where geography permits.

The scarlands remain historically and strategically important, especially as scars of the old fracturing, but they are not the continent's default condition. Much of modern Aeshkari life occupies ordinary green, agricultural, urban, riverine, coastal, forested, and upland terrain.

10.3 Peoples of the Aeshkari Continent

Aeshkar are the principal established civilizational people of the continent.

They need not be its only sapient inhabitants.

Future canon may establish:

native minorities
older populations
border peoples
island cultures
conquered populations
autonomous regions
migrant communities

without undermining Aeshkari continental dominance.

11. The Tazhuran Archipelago

The ancestral Tazhuran heartlands occupy a major tropical-to-subtropical oceanic archipelago.

This island system is geographically distinct from the established continental masses.

It should evoke the scale and isolation of a major volcanic island civilization without copying any particular real-world island chain.

11.1 General Form

The archipelago is centered upon:

one dominant great island

surrounded by:

several major satellite islands
smaller inhabited islands
volcanic islands
offshore reefs
uninhabited islets
sea stacks
smaller island chains

The exact number, outline, and final names of the major islands remain cartographic decisions.

The hard geographic principle is:

one great political and ecological heart-island surrounded by a broader island system

rather than one isolated island containing the entirety of Tazhuran civilization.

11.2 Geological Origin

The archipelago should possess a strongly volcanic geological history.

Its formation may involve:

oceanic hotspot volcanism
plate-boundary volcanism
uplift
subsidence
erosion
coral or reef development
collapsed volcanic calderas

At least one significant island or volcanic region should remain:

actively volcanic

Active does not mean continuously erupting.

It means geologically alive.

Eruptions may occur:

generations apart
decades apart
unpredictably
in localized volcanic systems

depending upon the final geology.

11.3 Tazhuran Landscape

Established Tazhuran geography requires:

jungle basin capitals
mountain-backed rain kingdoms
serpent rivers
stepped temple districts
humid lowlands
elevated interiors
ancient ceremonial centers

The great central island should therefore be large enough to support:

interior mountain systems
volcanic highlands
major rivers
tropical forests
rain-shadow variation
river basins
fertile volcanic soils
coastal plains
deep harbors

The islands should not all share identical ecology.

One may be:

wetter
higher
volcanically active
drier
reef-dominated
storm-exposed

than another.

11.4 Wider Troll Geography

The Tazhuran are the ancestral crowned line of Troll-kind.

They are not the only trolls.

Broader Troll-kind has spread throughout:

river deltas
jungles
swamps
islands
trade roads
frontier regions
mixed cities
and other continents

Therefore:

Tazhuran homeland does not equal total troll distribution.

12. Other Islands and Archipelagos

The existence of the Tazhuran Archipelago does not make it Eldarûn's only island system.

A world with Earth-comparable tectonics should possess many forms of islands, including:

volcanic chains
continental fragments
reef islands
barrier islands
glacial islands
river-delta islands
uplifted plateaus
isolated oceanic islands

Future cartography should deliberately include islands at multiple scales.

Not every island needs:

a kingdom
a unique race
a magical secret
a dungeon
or a civilization

Some are simply geographic landforms.

Others may become important because of:

trade
naval control
resources
migration
weather
piracy
religion
ecological isolation

13. Oceans, Seas, and Maritime Geography

Eldarûn possesses multiple major ocean basins.

The five great ocean names are fixed; their exact boundaries and planetary placement belong to Continents, Oceans & Seas and the master cartographic record.

At the planetary level, they must include enough water to produce:

true ocean crossings
major currents
storm systems
isolated maritime cultures
fisheries
naval theaters
deep-water barriers
island ecologies

Smaller maritime bodies may include:

marginal seas
inland seas
gulfs
straits
bays
sounds
channels
archipelagic seas

The distinction between an ocean and sea is geographic and cultural rather than magical.

14. Mountain Systems

Major mountain ranges in Eldarûn arise primarily through physical geological processes.

These include:

plate collision
subduction
uplift
faulting
volcanism
erosion

Mountain systems should influence:

rainfall
river sources
political borders
roads
trade
settlement
mining
defense
ecological zones

A large mountain range should cast a geographic shadow across the world around it.

If one side receives heavy rainfall, the opposite side may become significantly drier.

If a mountain chain divides kingdoms, crossing points should matter.

If rivers rise in highlands, those rivers must flow somewhere.

15. Rivers and Watersheds

Surface rivers generally obey familiar hydrology.

They:

begin in higher or wetter terrain
collect tributaries
flow downhill
occupy drainage basins
flood
erode
deposit sediment
eventually reach larger rivers, lakes, wetlands, inland basins, or the sea

Rivers should not randomly:

split repeatedly downstream without deltaic cause
cross mountain ranges without valleys
climb uphill
terminate without evaporation, infiltration, lake, or basin

unless specific supernatural canon explains the exception.

Major settlements frequently develop near:

navigable rivers
river crossings
confluences
deltas
fertile floodplains
freshwater access

Therefore river placement must precede final settlement placement wherever the settlement has not already been established.

16. Lakes and Inland Basins

Eldarûn contains:

glacial lakes
tectonic lakes
crater lakes
river-fed lakes
oxbow lakes
volcanic lakes
saline inland basins
temporary desert lakes
artificial reservoirs

Large inland waters can become:

trade corridors
climate modifiers
political borders
fisheries
centers of civilization

A lake is not merely decorative blue space on a map.

Its inlet, outlet, basin, and surrounding terrain matter.

17. Polar Regions

Eldarûn possesses northern and southern polar regions.

Their existence and seasonal behavior follow naturally from the planet's:

spherical form
approximately 23.44° axial tilt
24-hour rotational cycle
and approximately 365.2422-day seasonal year

At high latitudes, the axial tilt produces increasingly dramatic changes in daylight across the year.

Near the polar circles, this can create periods of:

extremely long summer daylight
extremely short winter daylight
prolonged twilight
seasonal absence of sunrise
seasonal absence of sunset

depending upon latitude.

Polar and subpolar environments may include:

permanent or seasonal ice
tundra
seasonal sea ice
glaciers
continental ice caps
cold ocean systems
polar islands
exposed rock
permafrost
mountain ice fields

The final extent of permanent ice depends upon:

latitude
altitude
ocean currents
continental arrangement
snowfall
and later climate modeling

The Stormfjords belong to Eldarûn's northern cold-world system but are not assumed to lie at the geographic pole itself.

Their established:

fjords
glacial valleys
cold seas
snow-fed waters
and storm-exposed high-latitude character

place constraints upon their eventual latitude.

Polar geography may contain:

native ecosystems
migratory animals
permanent settlements
seasonal settlements
old ruins
mineral resources
maritime passages

and should not be treated as empty white space at the edge of the map.

18. Climate Belts and Latitude

Planetary latitude meaningfully affects Eldarûn's climate.

This relationship arises principally from:

the curvature of the planet
solar angle
day length
Eldarûn's approximately 23.44° axial tilt
and the seasonal progression of its approximately 365.2422-day tropical year

Broadly familiar climatic latitude zones therefore exist, including:

equatorial
tropical
subtropical
temperate
subpolar
polar

These are tendencies rather than rigid borders.

A location's actual climate also depends upon:

altitude
mountain barriers
prevailing winds
ocean currents
continental interior position
coastal proximity
vegetation
nearby water bodies
and regional topography

Therefore:

a high tropical mountain can possess snow and alpine conditions
a cold-current subtropical coast can support desert
a warm ocean current can moderate a northern coastline
an interior rain shadow can create arid land beside wetter regions
an equatorial highland can remain cooler than surrounding lowlands

Latitude establishes the solar framework.

Geography determines how that framework is expressed locally.

This distinction is especially important when the master map assigns final latitudes to already established regions.

A later cartographic decision cannot place a region with firmly established:

glaciated fjords
tropical rainforest
major desert
polar conditions
or other strong climatic identity

at a latitude fundamentally incompatible with that identity unless another established geographic mechanism explains the exception.

The exact climate system is defined in Climate & Weather.

19. Tectonic Activity

Eldarûn is geologically active.

Its crust is divided into moving tectonic systems.

Over immense periods, these processes produce:

continental movement
mountain building
ocean basins
rifts
subduction zones
volcanic arcs
earthquakes
fault valleys
island chains

This means the modern map is not the map Eldarûn possessed in the First Divine Age.

Continents move.

Seas open and close.

Mountains rise and erode.

Ancient civilizations may now lie:

inland from former coasts
beneath sediment
below water
within uplifted terrain

Geological time exists independently from written history.

20. Natural Hazards

Natural hazards occur throughout Eldarûn as part of ordinary planetary behavior.

These may include:

earthquakes
volcanic eruptions
tsunamis
floods
droughts
wildfires
cyclones
hurricanes or equivalent tropical storms
severe thunderstorms
blizzards
landslides
mudslides
avalanches
coastal storm surge
extreme heat
extreme cold

These events do not occur constantly.

Their frequency depends upon geography.

A fault region experiences greater earthquake risk.

A volcanic arc experiences greater eruption risk.

A floodplain experiences floods.

A dry forest may experience wildfire.

A tropical ocean basin may produce cyclonic storms.

Specific supernatural disasters are layered on top of this natural baseline.

They do not replace it.

The full doctrine belongs to Natural Disasters & Extreme Events.

21. The Rootveil Beneath the World

The Rootveil is not a separate plane beneath the continents.

It is physical Eldarûn.

Its geography therefore exists in relationship to the same planetary body as the Surface.

21.1 Continental Rootveil

Beneath continental regions, the Rootveil may contain:

enormous cavern systems
root-vaults
buried rivers
blacklakes
mineral provinces
deep roads
fungal ecosystems
civilizations
fault systems
World Tree root networks

Continental crust provides broad zones in which large deep-world systems can develop.

21.2 Oceanic Rootveil

The Rootveil does not simply stop at the coastline.

Deep structures continue beneath ocean basins.

However, the character of oceanic Rootveil differs from continental Rootveil.

It may be:

more compressed
deeper beneath usable access
hotter
wetter
more faulted
more pressure-dominated
less cavern-rich
more dangerous

depending upon local geology.

Therefore it is correct to say:

the Rootveil extends beneath the oceans

without implying that a traveler can casually walk one continuous dry tunnel from every continent to every island.

21.3 Island Rootveil

Large islands, volcanic archipelagos, and continental fragments may possess their own Rootveil systems.

Some may connect into larger deep networks.

Others may be effectively isolated by:

oceanic crust
magma
collapse
fault zones
pressure
blackwater
impassable deep structures

The Tazhuran Archipelago therefore may possess Rootveil access without requiring every island to share an easy subterranean connection to the Primary Continent.

22. World Trees and Geographic Scale

World Trees possess root systems capable of interacting with vast sections of subterranean Eldarûn.

Their root networks may:

cross political borders
penetrate mountain systems
interact with aquifers
enter Rootveil regions
influence local soils
shape deep ecology

World Tree root geography does not replace plate tectonics or ordinary roots.

It overlays them.

The location of major World Trees must eventually be mapped because their presence may affect:

settlement
sacred territory
Rootveil access
ley behavior
ecology
politics

23. Ley and Geography

Ley Lines exist within Eldarûn's physical geography.

They are not replacements for geological structure.

A mountain does not exist merely because a Ley Line says so.

A river does not normally flow toward a ley nexus instead of downhill.

However, long-term ley influence may affect:

fertility
magical ecosystems
settlement
sacred sites
unusual mineral formation
World Tree growth
regional magical practice

The master map may eventually include a separate ley layer.

That layer must remain distinct from:

political borders
topography
hydrology

so that the world can be understood both physically and magically.

24. Geographic Hierarchy

For mapping and World Bible organization, Eldarûnian geography should follow a consistent hierarchy.

24.1 Planet

Eldarûn

24.2 Continental Scale

continents
major archipelagos
ocean basins

24.3 Macroregional Scale

major mountain systems
great plains
deserts
basins
forest belts
highlands
major river systems

24.4 Regional Scale

Examples include:

24.5 Local Scale

individual valleys
forests
lakes
river reaches
passes
marshes

24.6 Settlement Scale

kingdoms
provinces
cities
towns
villages
forts
ruins

Political borders should normally be laid over physical geography.

Physical geography should not be reshaped merely to make political borders convenient.

25. Cartographic Doctrine

The master map of Eldarûn must be built as an editable geographic system.

It should not be treated as a single decorative image that becomes impossible to alter without redrawing the world.

The preferred cartographic workflow is layered.

At minimum, separate layers should exist for:

coastline and landmass
elevation
mountains
rivers and lakes
biome
political borders
regions
settlements
roads
sea routes
Rootveil access
World Trees
ley geography

This allows later canon to change:

a border
city
road
kingdom

without accidentally changing:

a mountain
coastline
river
ocean

The physical world is the foundation.

Everything else sits upon it.

25.1 Source-Control Authority

For cartographic reconstruction, the Geography Master Ledger and its current Geographic Compendium control numeric source controls, donor/source identity, exact point placement, route geometry, and working cartographic status wherever older geographic prose conflicts with current manuscript or World Bible locks.

The controlling principles are:

established source-derived point locations do not move; the world around them is rebuilt
every discrete point-place must ultimately possess an immutable numeric control before final map generation
rivers and roads require polylines, forests and wetlands require polygons or envelopes, and mountain systems require ridge/envelope geometry rather than invented point locations
coordinate lock is independent of final naming; a name may change without reopening a correctly solved position
where source identity remains genuinely ambiguous, the location remains evidence-gated rather than being forced into false certainty

The external donor atlas is authorial scaffolding only. It preserves spatial density, functional niches, and route logic; it does not exist inside Eldarûn and does not control Eldarûnian culture, history, government, ecology, institutions, or final terrain design.

26. Authorial Geographic Design Doctrine

Eldarûn's cartography should combine two major design principles.

26.1 Earth-Like Physical Logic

The world should obey recognizable:

tectonics
erosion
climate
hydrology
glaciation
volcanism
watershed formation
coastal processes

unless an explicit magical exception exists.

26.2 Dense Epic-Fantasy Geography

The Primary Continent should support the geographic narrative density associated with a major classic fantasy setting.

It needs room for:

many cultures
long roads
wilderness
great kingdoms
frontier zones
mountains
forests
swamps
plains
deserts
ancient ruins
coastlines
trade networks

without requiring every story to cross an entire planet.

This is a functional design principle, not permission to copy another fantasy map.

Eldarûn must possess:

original coastlines
original mountain systems
original rivers
original continental silhouettes
original borders
original names

Existing story geography that was initially developed using another setting as spatial inspiration must be translated into an original Eldarûnian geographic system.

The goal is:

preserve narrative function, not inherited cartography.

27. What Is Already Fixed

The following planetary relationships are established and must be preserved by later cartography.

27.1 Planetary Physical Chassis

Eldarûn is an Earth-equivalent terrestrial planet.

The following are Hard Canon Locks:

mean radius — approximately 6,371 km
mean diameter — approximately 12,742 km
planetary mass — approximately 5.97 × 10²⁴ kg
average Surface gravity — approximately 1 g / 9.81 m/s²
mean solar day — 24 hours
sidereal rotation — approximately 23 h 56 m 4 s
axial tilt — approximately 23.44°
tropical / seasonal year — approximately 365.2422 days
sidereal year — approximately 365.2564 days
Earth-comparable average solar energy at the Surface

These values are coupled to the established orbital architecture of Seryn.

They cannot be substantially altered without reopening Celestial Structure of Eldarûn.

27.2 Planetary Surface

the majority of Eldarûn's Surface is covered by ocean
land is divided among continents, large islands, archipelagos, and smaller islands
natural geological and hydrological processes function normally unless canon establishes an exception
Eldarûn possesses northern and southern polar regions
tectonic activity, volcanism, erosion, glaciation, and sedimentation function as ordinary planetary processes

27.3 Major Land Architecture

Eldarûn possesses seven major continental-scale landmasses.

One is the Primary Continent.

One is the principal Aeshkar-dominant continent.

One is the Ferathi-majority continent within the wider maritime sphere between the Primary Continent and the Aeshkari world.

One is the major Southern Polar Continent.

Three additional major nonpolar continents remain available for later development.

The Tazhuran ancestral homeland is a major oceanic archipelago and is not counted among the seven continents.

Additional microcontinents, large islands, archipelagos, and continental fragments may exist without altering the seven-continent count.

The final planet must preserve sufficient undeveloped geographic space for future civilizations and stories.

27.4 Primary Continent

The Primary Continent contains principal established regions including:

Dawnlands
Heartforge Vales
Sands of Serath
Redmark Plains
Stormfjords
Xer’Arun Waste
Ashfang Region
Ashfang Mountains
and the established geographic theater of the major stories

The Stormfjords lie north of the Redmark Plains.

Existing BONDS route relationships recorded in §9 are binding cartographic constraints.

27.5 Aeshkari Continent

geographically separate from the Primary Continent
separated by substantial ocean
dominated politically and culturally by the Aeshkar
contains scarlands, basalt provinces, crater basins, fortress-cities, border principalities, and ordinary habitable terrain
is a true ecologically varied continent rather than one uninterrupted hellscape

27.6 Ferathi Continent

geographically separate from both the Primary and Aeshkari continents

occupies the wider maritime sphere between those continental worlds

biased closer to the Aeshkari continent than to an exact midpoint

separated from both neighbors by substantial ocean crossings rather than functioning as a land bridge

supports enough ecological breadth for tropical coasts, rainforest, temperate forest, savanna and grassland, wetlands, dry interior belts, highlands and mountains, reef-rich coasts, islands, and both aquatic and avian Ferathi populations

final proper continental name, exact silhouette, coastline, and precise position remain cartographic dependencies

27.7 Tazhuran Archipelago

tropical or subtropical island system
centered upon one great principal island
surrounded by multiple major and minor islands
volcanic in geological origin
includes at least one geologically active volcanic region
supports jungle basins, mountains, great rivers, rain kingdoms, and ancient temple civilizations

27.8 Rootveil

physical part of Eldarûn
extends beneath continental and oceanic geography
does not automatically provide easy continuous passage beneath every ocean
may exist beneath islands in locally distinct forms
Surface coastlines do not represent the physical edge of the Rootveil

27.9 Existing Story Geography

The route sequences, travel durations, local directional relationships, and transportation constraints listed in §9 are established evidence.

Future maps must conform to those relationships.

Where later cartographic work discovers a genuine contradiction among old sources, the contradiction must be explicitly reconciled through the Canon Decision Ledger rather than silently choosing whichever version is most convenient.

28. What Remains Map-Dependent

The physical chassis of Eldarûn is fixed.

The number of major continents is fixed.

The broad macro-relationship among the Primary, Ferathi, and Aeshkari continental worlds is fixed.

The five great ocean names and the common inventory of approximately fifty-four major seas are fixed.

The following remain dependent upon master cartography:

final continental silhouettes
proper names of the seven continents where not yet established
exact continental positions and relative size ranking
exact placement and coastline geometry of the Aeshkari continent
exact placement and coastline geometry of the Ferathi continent within its fixed macro-relationship
exact placement and orientation of the Tazhuran Archipelago
exact boundaries of the five named ocean basins
placement of the approximately fifty-four major seas
coastlines
tectonic plates
mountain systems
rivers and watersheds
lakes
polar coastlines and ice
ocean currents
final geographic coordinates and nonpoint feature geometry
unmapped homeland relationships
straits, gulfs, bays, reefs, trenches, ridges, and island distributions

These are deliberate cartographic dependencies.

They are not permission to ignore existing canon or current source-control locks.

28.1 What the Map May Decide

The master map may determine:

the precise shape of a coast
the precise bend of a road
the exact latitude of a settlement
the exact course of a river
the exact width of a mountain chain
the position of unmapped seas
the number and shape of additional islands
the location of future regions not constrained by existing canon

28.2 What the Map May Not Overrule

The master map may not casually contradict:

Seryn-dependent planetary scale
the 24-hour day
the approximately 23.44° axial tilt
the established solar year
established route order
established travel duration
established transportation mode
established local directional relationships
established climatic identity
established mountain-country relationships
established continental separation of the Aeshkar
established island homeland of the Tazhuran

For example:

The final map may decide the exact latitude of the Stormfjords.

It may not place them within an equatorial tropical belt while retaining their established glacial-fjord ecology without introducing a specific physical explanation.

The final map may determine the exact shape of the road between Trifang and Branloch.

It may not redirect Branloch east of Trifang when established route canon places the journey south along the Trifang Trail.

28.3 Cartographic Constraint Extraction

Existing manuscripts and geographic source material contain additional usable geographic evidence beyond the locks already summarized in §9.

Before the final continental atlas is considered complete, those sources should be systematically audited for:

compass directions
travel times
stated distances
roads
passes
river crossings
settlement approaches
mountain relationships
coastline references
transport changes
terrain transitions
visible landmarks

Verified statements should be transferred into the master Cartographic Constraint Ledger.

The final map should therefore emerge from:

existing evidence → reconciled constraints → physical geography → finalized cartography

rather than from arbitrary coastline design followed by attempts to force established stories onto it.

29. Foundational Principle

Planetary geography in Eldarûn can be reduced to one rule:

The world must make physical sense before the map is allowed to become fantastical.

Mountains create consequences.

Rivers connect places.

Deserts have causes.

Oceans create distance.

Islands create isolation.

Fjords come from landscape history.

Volcanoes belong to geology.

Settlements respond to water, roads, terrain, climate, and resources.

Magic can alter any of these things.

When it does, the alteration must be meaningful enough to deserve explanation.

Summary

Eldarûn is a full-sized, Earth-comparable terrestrial world with familiar gravity, planetary scale, oceans, continents, polar regions, tectonic activity, watersheds, mountains, rivers, islands, and climate zones.

Most of the Surface is covered by ocean.

The established planetary architecture requires seven major continental-scale landmasses.

The Primary Continent is the principal shared landmass of most currently established civilizations and contains regions such as the Dawnlands, Heartforge Vales, Sands of Serath, Redmark Plains, Stormfjords, Xer’Arun Waste, and the known geographic theater of the major stories.

The Stormfjords lie north of the Redmark Plains, creating a natural progression from northern maritime coldlands into broader interior Veydran country.

The Aeshkar possess a separate continental homeland across substantial ocean. Their continent includes the scarlands, basalt provinces, crater basins, fortress-cities, border principalities, and ordinary habitable ecosystems required to sustain a true civilization.

The Ferathi possess a separate Ferathi-majority continent within the wider maritime sphere between the Primary and Aeshkari worlds. It is biased closer to Aeshkar than to an exact midpoint while remaining separated from both neighbors by substantial ocean.

The Tazhuran ancestral heartland is a major tropical-to-subtropical archipelago centered upon one great island and surrounded by additional volcanic islands and islets. Its geography supports jungle basins, mountain-backed rain kingdoms, great rivers, ancient temple-cities, and at least one active volcanic region.

Broader Troll-kind exists far beyond the Tazhuran islands.

The Rootveil is physical Eldarûn and extends beneath both continental and oceanic geography, though deep-ocean Rootveil systems are not assumed to provide easy continuous passage between every landmass.

Eldarûn's mountains, rivers, deserts, volcanoes, climates, and natural hazards arise primarily through familiar physical processes.

The final master map must preserve already established story routes, distances, and directional relationships while giving them an original continental and regional geography.

Exact coastlines, final continent names, ocean-basin boundaries, global mountain systems, river networks, and precise continental positions remain dependent upon master cartography; the seven-continent count and five formal ocean names do not.

The governing rule is:

Eldarûn is not a map with places drawn onto it. It is a planet whose physical geography determines where those places can truthfully exist.
