Bitterblood was a monstrous godbeast similar to a corpse-worm but with the size of a moon that was found by Sigmar during his search of Nagash. Bitterblood was defeated but when its body was destroyed ten thousand of its formless children wriggled out from its belly and each of them killed only spawned more. Thus Sigmar locked the horde in a Stormvault beneath the Bitterblood Caverns in northern Stygxx.
