What is Bodach?
1.
Mysterious and forboding shadow creatures from the dead that inhabit this world unseen, not yet ready to embrace they're final destiny. They are harbingers of death, destruction, and evil, the embodiment of Satan him/herself.
In the room where the girls were sleeping soundly he could see five bodachs hovering over the bed menacingly.
(from "Odd Thomas", Dean Koontz novel)
