One of the most talented and innovative wizards in the Land of Een was Shaden Shiverbone. He demonstrated talent from an early age, accomplishing many feats that astonished his master and the Council of Elders.
In his later years, Shaden Shiverbone took Leerlin Lurk as his apprentice. Shaden tried to train Leerlin in the ways of magic, even when the mighty Een Oak refused to grant the wayward boy a wand of Eenwood.
Eventually, Leerlin would betray his master, stealing both his shadow cloak and his special Kazah stone.
