Eudoxia

Eudoxia was a plane of eternal night, lit only by a permanently crescent moon. The most powerful civilization, a branch of surface-dwelling drow, followed a heirarcy of warrior-priests, gaining merit through human sacrifice to their dark gods.

Recently Eudoxia was absorbed by Dis due to the influence of the Planarch Codex. Eudoxia-in-Dis is a grand complex of stone pyramids and towers, surrounding a great gladatorial arena.
