Cree Bega was dispatched as commander of three dozen Mwellrets meant to serve under the Ilse Witch. The Witch particularly disliked Bega, because he was more resistant to her magic than most and considered her inferior. The tension between them continued until the Morgawr himself came and brought Bega back under his command.
The Morgawr also gave Cree Bega the seer Ryer Ord Star, whom he and his Mwellerets gang-raped and tortured.
Following the airship Jerle Shannara to its hiding place on the island of Mephitic, Bega accompanied his master into the ruins of the magic fortress there. He boarded the nearly abandoned Jerle Shannara, and there confronted the young Elven Prince, Ahren Elessedil. However, thanks to the combat training he had received from Ard Patrinell, Ahren overcame Bega, wounding him fatally with his sword.
