Centuries ago, in the scorched desert of Niserri, an evil high priest was defeated before he could finish a powerful ritual designed to free his dark god into the world. When the mummified remains of this priest are reawakened as a powerful undead monster it's falls upon the heroes to stop him from finishing the ritual he started so long ago. Failure means letting the entire world fall into an eternity of chaos and darkness.
