Zhengyi

Zhengyi the Witch-King was once a Red Wizard of Thay, but later became an enormously powerful lich and servant of the demon prince Orcus. In the far north of Vaasa, the sister kingdom of Damara, Zhengyi raised a fortress called Castle Perilous and summoned the various monsters of the lands to him.

History
After raising an army, the Witch-King repeatedly attacked the kingdom of Damara over twelve years, killing its king and ruining the land. He was finally destroyed by a party of adventurers led by the Gareth Dragonsbane. Baron Gareth would eventually become King Gareth of Damara.
