Ulan Vasx

From King's Quest Omnipedia

Ulan Vasx was a famous sorcerer in majicians' circles. He taught at the Magicians' Academy for a while. He was also known to have attempted to save the Duchy of the Solicitous Boar from the Entomon Wilson's Wandering Weevils by summoning a demon to dig a deep hole, and then blew a magical wind blowing the weevils into the hole. The demon went into the hole and closing it after the weevils. While he stopped the weevils the demon's foul magic corrupted the land turning it into a cursed desert.
