He is a Siphoner, a witch born without the ability to generate his own magic but possessing a rare power that allows him to siphon and use magic from other sources . Because of this, Kai's parents and the rest of the Gemini Coven (excluding his siblings) treated him as an abomination, which eventually caused him to go insane and kill the siblings born to replace him . The coven then harnessed the power of a solar eclipse to trap him in a purgatory dimension, which kept him trapped in a snapshot of May 10, 1994 for 20 years . </P> <Ul> <Li> Played by Annie Wersching </Li> <Li> Seasons: 6--7 </Li> </Ul>
