The setting of Apotheosis takes place on the planet Atlas. It has a single moon, and is host to three major continents: Atollia, Aecher, and Abaddon, separated by large oceans and island chains. There is also the smaller tropical continent of Agonzia, and the island state of Indigo. There are four oceans on Atlas: the Oceanus Secutorum, Oceanus Procellarum, Oceanus Tyrannum, and the Oceanus Arcticorum.
The areas to the extreme north and south of the planet are largely unexplored and therefore unmapped, and it is assumed that there are no habitable lands beyond the ice flows above the Oceanus Secutorum and below the Oceanus Arcticorum. No explorer or expedition has successfully surveyed the areas beyond the unbreakable ice.
Atlas has climates and temperaments similar to that of Earth, chillier near the poles and more temperate near the equator. Storms, earthquakes, and other natural phenomena are more or less common in certain areas.
