Malistaire....

Malistaire Drake is the main bad guy of the game until you defeat him in Dragonspyre

Life as the death teacher
Malistaire was the death teacher at Ravenwood once apon time. His students loved him, and he meant well. But one terrible night, his wife, Sylvia, the life professor got ill. And eventually she died. Malistaire missed her so much that he couldn't go on. So he quit his job and the death school sank to the ground. His best student, Malorn Ashthorn, now teaches the death students, called Necromancers.

The Search for the Krokonomicon
Malistaire began terrorizing WC until the savior came along and chased him away. Malistaire went to KT to search for the krokonomicon, which he belived could bring his wife back. But the savior saved KT and the Marleybonians took the nomicon to the MB. In MB, Malistaire joined with Meowiarty, a cunning cat burgler. But the savior came and defeated Meowiarty. Malistaire got the nomicon just in time though, and ran off to MS. In MS he joined with the Onis and made the Emporer ill. Again the savior came along and defeated he onis and healed the king. So Malistaire ran to DS. In DS  the savior got a drake to fly and with the help of the Myth Professor, Cyrus Drake (Malistaire's brother), defeated Malistaire. Malistaire than realized that Sylvia would not want him to do this, so he joined Sylvia in the spirit world. That was the last we've heard of him.
