Kadaena (Ir."Slayer Empress") also known as Kadaena Throk Farok (Ir."Kadaena, forbidden guardian") was believed to have been one of the Lords of Essence and the last ruler of the Althans. Her cruel tyranny ended when she was decapitated by her uprising cousin Utha, although the internal strife among the Althans continued for some time and descendants of Kadaena's followers and cults continued to trouble Utha's successors.
