Khothe

Khothe is the shadow of Eibur, who transcended to demi-godhood among the Under Planes when he singlehandedly brought about the Sundering by creating a rift between the Under Planes and the Material Plane, causing all manners of evil to spread across Alaria. The Prime Elementals had to start the world over to undo the damage he had done. The celestials killed Khothe as punishment, and bound his soul and shadow to the Ethereal and Nethereal Planes so he would never be at peace again. Eventually, his shadow was enslaved by the Thespians, while his soul withered and grew more corrupted as well.
