It is the mortal remains of these troglodytic beasts that the Ghoul Kings of the caverns bind to their service. The binding process comes easily to these reclusive Vampires, for Strigoi Ghoul Kings and Terrorgheists have much in common. As Dark Magic swirls around the monstrous cave-creature, a bond of blood is formed between master and beast. Much like any other creature that drinks from a Ghoul King's veins, Terrorgheists have necromantic power running in their blood that can heal even the most severe of wounds.[1a]
