The Ice Jester is the major antagonist of Feast of Legends. He appears in most quests, and is the "boss" that you face in the final quest. He stands in complete opposition to Freshtovia's values, and is thus Queen Wendy's nemesis.
The Ice Jester is a deadly sorcerer who knows how to create live creatures such as the Frÿsta and other fiends to aid him in his quest against Queen Wendy.
