"In the shadowy annals of Malekith's dark experiments, Zygor is the evidence of the twisted depths of necromantic arts. Born from the bizarre fusion of forbidden magic and the remains of an orc who once sought to conquer the tower, Zygor is neither fully alive nor truly dead. This undead sentinel, a grotesque blend of orcish might and necromantic energy, is a look of the tower's tumultuous past.

The origins of Zygor remain cloaked in mystery. Whispers suggest that he is the resurrected remnants of one of the many orcs who perished in their ambitious assault on the tower. Malekith, ever the opportunist, saw potential in the fallen and breathed unholy life into the orc's remains."
