The origins of this vile creature, as well as how it was created are unknown. The bones and blood located in the room it is fought in, along with the skulls seen inside itself, indicate that there have been numerous occasions where people tried to break into the Coliseum, only to die by Bleigock. It is also possible that those who were executed in the Coliseum had their corpse thrown into the pit, where they were devoured by the Bleigock.
