The Gemini Coven gets its name because the leaders are always twins. Well, the leader. They merge their magic when they're twenty-two and the stronger twin survives. Kai never had magic of his own. He could only siphon it from other people. My father didn't want to risk Kai becoming the Coven leader, so he kept having kids until Liv and Luke were born. When we turned twenty-two and Kai realized we weren't going to merge, he started killing all our siblings. I managed to hide the twins with a cloaking spell, but he gutted me with a kitchen knife. So I helped lock him in a prison world, and in exchange, I got to leave the Coven and have a normal life. Unfortunately, he escaped recently.
