Gelk

Gelk is a level 42 elite undead centaur found in Maraudon. In life he was the second alleged offspring of Zaetar and Theradras, and also the first Khan of the Gelkis clan, which is likely named after him. He manifests when the Amulet of Spirits is used on the Spirit of Gelk.

Temuejin also shares the title Second Khan.
