When Unegen meets a fellow shaman, Ghazan, at the gateway to Tam, another realm, he is gifted with a vision inducing sap. Forced to flee his tribe, Unegen finds Ghazan in the Omni Desert, where Unegen is tricked into taming a demon, that Ghazan uses as a disguise to smuggle himself past the gatekeeper, Yabash, and into Tam. Furious, the gatekeeper Yabash tasks Unegen with hunting down Ghazan.
