Sati is a demigod of the Angarian pantheon. In one episode he revives the Indian after his death.
In another his role is more complex: a manipulator who poses as Tartar to deceive the companions. His plan is to use them to eliminate the minions of Tii, then lock all the defeated gods in the Abyss, and force the Dark Queen to retreat for lack of followers. He says: “Look what I am going to end up doing: I will betray Satan, you the queen.”
He is the first to fall in the final battle.
