Shivvok

Shivvok, Lord of the Shadow Realm, as he calls himself, is supernatural being that was once a human named Endesso Dreik. Endesso was corrupted by the Terror Scythe after he helped to enchant it during the Aruel Ritual.

Appearance
The fact that Shivvok has been corrupted is reflected in his appearance which was described in Mysteries of the Rift,

"Silently a breeze started to form in the room. A nearby candle blew out as the wind swept by. The smoke from the extinguished candle began to move in a peculiar way, flowing down to the floor and then forming itself into what appeared to be a foot. Long after any other candle’s wick would be cold, the smoke continued to flow, almost with a mind of its own, until it made a vaguely human shape. A gust of air blew the grey smoke away revealing a horribly mangled figure beneath.

His skin was shriveled and grey, covered by a black tarlike substance that dripped from his skeletal body. One of his hands was missing, leaving the jagged bone of his arm showing. Above his bright red eyes, a part of his skull was smashed in and a black pulsating mass could be seen within--presumably his brain or what was left of it. His corrupted appearance was truly revolting an would be enough to horrify nearly anyone."

During Raxus' Time (Original Mysteries of the Rift)
The entire conflict in Mysteries of the Rift can be blamed primarily on Shivvok. In order to keep Shivvok binded, Nyrok had no choice but to gather enough souls to renew the binding's enchantment on the night of binding. If Raxus had actually managed to stop Nyrok, he would have inadvertantly caused the corruption of to A'thos.
