Kaecilius is a sorcerer.
Kaecilius was introduced to the Masters of the Mystic Arts through Karl Mordo, following the death of his wife and son. Disillusioned with the Ancient One, Kaecilius became a follower of Dormammu and formed the Zealots. Kaecilius successfully brought Dormammu to Earth, although was eventually defeated by Doctor Strange, becoming subservient to Dormammu and living the rest of his life as a Mindless One.
