He is Sha'Rae's father and a rebellion member who betrays his cause to ensure the safety of his family. Unfortunately, he is betrayed in turn!
Kasuf: "I found out what Sek-Duet is doing with all the rebels. The spell he stole from the yaga spellbook calls for a strong magical power source. That source is the Orb of Light. The spell also calls for ' the life forces of 100 people who call you an enemy ' .
Kasuf is a reference to the character of the same name in the movie Stargate and the series Stargate SG-1, who lived on a desert planet.
