The Aulesiri people are the dominant population group of the Aulesiri Empire, and in all of the continent of Jyotnun (including the Northern Eye), as well as northern Surotsi. While the Aulesiri are frequently referred to as a single ethnicity, they are quite varied in appearance and traits, depending on the regions they adapted to over millennia on the continent of Euleshun.

The vast majority of the Aulesiri people follow the known world's dominant religion, the Pale Faith. This religion focuses on the worship of the Jade Moon and a prophet known as Luseysi, who led the Aulesiri people from the northern continent of Euleshun during the Aulesiri Ruin, when a series of natural disasters annihilated the old civilization's ancestral lands.
