Zattar

Zattar was a human wizard who was part of Talek Grimdark's conspiracy to take over Karthmoore. He was assigned to be the advisor of Lord Nigel Idun in Dunmire. Zattar used his magical abilities to dominate Nigel's mind and slowly drive him mad. In retrieving their stolen items from the Dunmire mansion, the PC's discovered Zattar's plans during a party in honor of Schephard's Heart, and confronted and killed him, ending his control over Lord Nigel.
