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 east 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 through the fen.

Fluke Peninsula
The fluke peninsula is a peninsula located in the west of North Adustia. It is characterized by its highly divergent biota from the rest of North Adustia, equivalent to South America when compared to North America. 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.

Hair Steppes
The hair steppes are cold steppes 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. Travel through these steppes are only facillitated through stilts or tall mounts.

Heresiarch's Island
= 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.
