Kespria

Kespria is the name given to the known populated world - i.e. the collection of sky islands where people live. It is widely assumed that there are other island clusters elsewhere, but Kespria is (for the most part) an isolated world of its own. Beyond the boundaries of what is classified as Kespria is Open Sky

The islands of Kespria are clustered in three altitude bands, known simply as the Low Isles, the Mid Isles, and the High Isles. Islands exist outside these bands, but are few and far between and are generally uninhabited.

The Low Isles have the most land, and are home to many civilizations, but the most populous and most technologically advanced nations are found in the Mid Isles. In the High Isles, weather tends to be more extreme, and only people naturally suited to such environments can endure living there.
