Early in Auldrant's history, all of its continents were merged into a large, unified land mass that experienced a continental drift over time, eventually resulting in the geography depicted in the story. The world of Auldrant is divided into two separate layers: an outside shell called the Outer Lands and an underground ocean of deadly miasma and mud known as the Qliphoth. Originally, the Outer Lands resided within the area now occupied by the Qliphoth, but a natural disaster caused it to fill with miasma, and the people were forced to raise the land and live in the sky through the efforts of a plan known as the Float Project.
