Thulsa Doom's evil snake-god, Set, is bringing him back from the grave so Doom can have vengeance on Sonja. But Set has his own hidden agenda. As Doom rises from the hellish depths to smash Sonja's palace, Sonja is lucky just to escape with all her limbs attached. Doom owes a heavy debt to his god Set for his new-found power. Set didn't revive Thulsa out of charity; it needs the undead sorcerer to carry out a horrific rite that can only be performed once every thousand years. The results of this dark ritual? Only Set knows the full truth... The Queen Sonja Volume 4 TP collects issues #16-20 [the "Son of Set" storyline], along with a complete cover gallery.
