Regions



The known world is split into 5 main continents with several major island chains. At the center of the world, to the immediate north and south of the sunspire, is Adustia. Adustia is partitioned by the sunspire and bodies of water into a northern and southern part with highly divergent biota. To the south of Adustia is Ludibria, named after a sea in the middle of the continent which resembles a grin. To the northwest of Adustia is Imia, a continent located entirely within the umbral zone and the only continent with parts beyond the world's end waterfall. To the east of Adustia across an ocean is Phthorea, another umbral continent which intersects with the wall. To the north of Phthorea are the Sipid Islands, an island chain which terminates at the wall. To the immediate west of the Sipid Islands is Galagea, a lost continent with biota unlike anywhere else in the known world.

Biogeographically, the terrestrial oceans of the known world can be split into two. The Irretic Ocean is to the east of Adustia, while the Cataractic Ocean is to its east. The Cataractic ocean generally has lower salinity, lower temperatures, greater depth of water, and is characterized by biota which somewhat resemble that in the skysea and abyss.

Listed below are some notable regions across the known world, including terrestrial, aquatic, muric, subterranean, caelar, and even abyssal sites.

= Terrestrial = Terrestrial regions are all those which are above sea level but do not extend into the skysea. They are categorized in terms of what continents they lie on, or in the case of islands, which bodies of water in emerge from.

Dust Sea
The dust sea is an enormous desert directly to the north of the sunspire comprised of miniscule grains of worn-down glass. The individual grains are fine enough to flow in waves when wind blows and scatter in cyclones when strong gusts rage. Giant heads rarely and unpredictably summon rain from the skysea, dowsing the dust sea into a cluster of shallow lakes which slowly dessicate.

Foam Fen
The foam fen is a tropical swamp to the west of the dust sea, chracterized by a detergent-producing bryozoan known by the inhabitants as foam-moss. The detergent foam-moss produces coats the otherwise typical zosterophyll fen in an iridescent foam. Land within the foam fen are mats of peat and tangled tree roots which slowly drift around.

The Peritelmic
The peritelmic describes a series of gallery forests and formic savannahs which surround the foam fens. Termite-like colonial vendobionts have nearly completely outcompeted megafaunal herbivores here, their colossal mounds constituting the most characteristic view of the region.

Fluke Peninsula
The fluke peninsula is located in the west of North Adustia, characterized by its highly divergent biota from the rest of North Adustia. The centerward parts of the peninsula are covered by towering casttrees, a holobiont of eusocial caddisflies and ferns. Ghoststars prowl the edgeward parts of the peninsula, their near-invisible tentacles swaying among barren fields. Mothbeasts and flybeasts give way to giant netwings - a polyphyletic group to include megafaunal owlflies, spoonwings, mantidflies, and snakeflies.

Hair Steppes
The hair steppes are cold steppes in the north of North Adustia characterized by the dominant cyanoarchaea vegetation which grow in hair-like mats. The cyanoarchaea colonies of the hair steppes are extremely tough and easy to be tangled in. Bands of giant wandering tickspiders and colossal trainsnakes prowl these lands, leaving the only viable paths through in their wake. Travel otherwise is only facillitated through stilts or tall mounts.

Glass Desert
The glass desert is a harsh and arid desert home to radiotrophic tube worms and unusally large sandfish. The heat of the sunspire has melted the sand here, leaving them to condese into jagged glass hills. Very little live here because of periodic scalding-fogs that instantaneously cook anything they touch.

Ashsparge Volcano
At the heart of the largest volcanic chain in Adustia is the stirring Ashsparge mud-volcano. Ancient activities have dug immunerable massive tunnels into the volcano, extending up to 4 km underground. These are filled with a variety of blind heat-loving biota which make tremors felt across the region.

Stonefloat Sea
Stonefloat Sea, north of the Ashsparge, is an immense hypersaline lake famed for its floating stone-glaciers. The alkaline water dissolves nearly all biota immersed within; the only ecosystem here is supported by the work of telephoretic heads that make freshwater from brine.

Kindled Pass
Kindled pass is the only lucent part of Ludibria, located at its very north. Here where the last sunlight fades to twilight, miniature shrub-forests grow in crimson patches. The biota here is uncharacteristic of Ludibria's giant molluscs and flightless jetbirds, but instead resembles the arthropod-dominance of South Adustia.

Black Plateaus
The Black Pleateaus are an immense flat highland which lies at the center of East Ludibria. Unnaturally rich in metals, especially iron, lead, and iridium, the Earth has taken up a rusted reddish-black tinge. The Stellar Skychain links the plateaus to the skysea, shading much of the center in a dense umbra. Countless precursor ruins dot the landscape, populated by remnants of ancient genetic engineering schemes.

Dune of Shells
Hidden to the north by black plateaus and south by wrought mountains, the Dune of Shells is the largest desert in Ludibria. Unlike Adustian deserts, composed of shattered glass and obsidian, the Dune of Shells is made of billions of micromolluscs, all writhing over eachother. As such, the dune has no stable borders, marching through central Ludibria aimlessly to leave snail-studded ruins in its wake.

Wrought Mountains
By the northern front of the Cackling Sea are the Wrought Mountains, a chain of immense orogenies in the shape of various spiked icosahedra. mat-like bivalves encrust the chain, fed on by a variety of jetbirds and greatsnails. Despite unprecedented consensus between the nine largest scholarly centres of the world that these mountains were constructed by precursors, no artefacts nor even ruins have been discovered. Those who dig too deep become afflicted by unexplained illness and hence perish.

Contrived Seafront
The Contrived Seafront lie to the south of the Cackling Sea. Made up entirely out of wall material, it is hard to say if they are even a natural formation. Innumerable people have tried to conquer this land, from wall-quarrying merchants to starhailing missionaries. No settlements have survived for more than a generation.

Moonscorched Ruins
Past the blood-lakes of central Imia hangs Imia's Moon, under which lies the Moonscorched Ruins. By shape alone, the terrain is near indistinguishable from a lucent forest in North Adustia, but nothing here has colour nor texture. What would be wood, or sand, or stone, or even the flesh and blood of an animal have been replaced by a white substance Imian scholars argue is analogous to wall material. Nothing grows in the ruins, and any who linger too long are doomed to stay forever as statues.

Twin Ichorflows
The Twin Ichorflows are a pair of slow-flowing whitewater rivers which support an immense river delta system in south Imia. The unnaturally torrid water extends kilometers beneath the surface, getting hotter the deeper one dives. The rivers' warmth supports most the Imian civilizations either directly or indirectly, shielding them from the oppressive umbral cold.

Balefire Archipelago
The Balefire Archipelago are a lucent oasis in an umbral sea. The miniature sunspire at the zenith of the islands supports a parallel phototrophic ecosystem evolved independantly from the mainland, where rhodophytes replace lichen and landjellies replace plants. Inexplicably, skysea fish seem entranced by the miniature sunspire, throwing themselves to their death in frequent fish rains.

White Pass
Between Galagea and the Sipid Islands is an ice sheet shrouded by constant blizzards, inhabited only by sealmoths and turtlesnakes which live on the edge of the sea ice. Well-prepared Idbëkian missions cross the pass to harvest Galagean fungus species found nowhere else, though very few return.

Bridge of the Laughing Man
In the far east of Ludibria and South Adustia sits a ruined greatbridge which would connect the two continents. Several kilometers wide and made of indestructable metal, it is a mystery how or why it has been bisected and shattered across the Ludibrian Sea. The namesakes of the bridge are a series of colossi across the structure, depicting contorted alien abominations that echo an ungodly laugh in the exact same voice.

Heresiarch's Island
= Aquatic = Aquatic regions are all those which are resevoirs of water at sea level in the betweenlands or any submerged region within them.

Straight of Imia
= Muric = Muric Regions are all those which are either directly on the wall or within the wall. These include wallside biomes, but also atria. Muric regions are categorized by which continents or oceans touch them.

Greenwall
= Caelar = Caelar regions are those which are in, or extend from, the skysea. These regions are categorized based on the continents or oceans that are directly under them.
