Quzira

Quzira was the first person to be declared as a champion of Lyssa. She led a war against the Kingdoms of Man and managed to claim enough land to start her own kingdom, the Kingdom of Shadow.
In The End, Quzira completed a grand ritual destroying Vitem Morta and subsuming his divine essence. This came at a cost though, as Quzira herself was also destroyed as her essence merged with Vitem Morta's. This created a new gestalt being known as The Hollow Queen.
