Doctor Strange

Like many students at Kamar-Taj, Kaecilius arrived at the mystical compound seeking the secrets of The Multiverse. He turned his back on The Ancient One and her teachings when he believed certain knowledge was being kept from him. It's within these forbidden powers Kaecilius sees the answer to all mankind's suffering—the ability to alleviate the pains of the human condition. Kaecilius, joined by his Zealot followers, will use every malevolent tool at his disposal to see our reality melded with shadowy powers of this other dimension even if it leads to the destruction of existence as we know it.
