True Necromancy, the trap presented as a gift he had received from the Strigoi he met previously. Unlike normal necromancy that simply used corpses as a puppet for magical energies to manipulate. True necromancy called back the spirit of one recently deceased. It allowed them to keep their memories, skills, and abilities while increasing their power. The gift of unlife was the name for the increase in an undead's power. Sael had been proud of himself for figuring out the trap what felt like ages ago. All undead created with true necromancy came back fueled by hatred and with a need for vengeance.
