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, caelar, and even abyssal sites.
