There were two sister of two different kinds. There was Темноте Mangle, She is the "Queen" of the Shadow-Demon Fox kind. Then there was her Sister Pounca Fordekte, the "Queen" of the Black-Mystic Panthers. But in a point of time, one of their tribes/kinds will die. When they grow old to a certain point of time, they will have to battle to the death for their own kind to live along with one of them, titled as "Ruler of Darkness" and the other must die or both will die. But one problem with one of them, Темноте loves her sister as a best friend, she never want to kill her. But on the other hand, Pounca is willing to kill her own sister to keep her clan alive, so, who will Stand and who will Fall.
