Children of Juru

The Worldkiller Coven was an inner circle of witches native to the planet Krypton. Although they lived among a science-centered society, this cult derived their power from the art of dark magic. It was this coven that, in accordance with an old prophecy, created the Worldkillers.

History
From what little has been revealed of the group, the Worldkiller Coven followed a polytheistic belief system which incorporated all of Krypton's deities - chief among them being the red sun god Rao, the creator of all Kryptonian life. Thus they studied the Book of Rao's prophecy.
