The Terrorgheist is a monstrous undead bat-beast raised by the flesh-eater-courts and the soulblight-gravelords to serve as a living engine of terror. A skeletal horror of vast leathery wings and exposed ribs, it emits a deafening death-shriek said to stop the hearts of those who hear it.
In life these creatures were giant carrion bats that roosted in the ruins and mountain crags of the Mortal Realms. Reanimated through dark sorcery, they retain a ravenous hunger, tearing prey apart with hooked claws and cavernous jaws. Their piercing scream is a weapon in its own right, capable of slaying warriors through sheer supernatural dread.
The Terrorgheist is often ridden into battle by the deluded Abhorrant nobles of the Flesh-eater Courts, who imagine the shrieking horror to be a noble steed or majestic griffon. Whether ridden or wild, the Terrorgheist descends upon its victims from the night sky, a screaming omen of death made manifest in bone and rotting sinew.
