Bloodborne explains how beast came to be and what the gods are. This was interesting to read like fan fiction but just a tad irritating when your speculation is more about what you want rather than what you can see. They chained up coffins becsuse when people are taken over by the blood of the old ones they become beast. Most seem dead, but then change into beast. They hung the giant beast because they were hunters. Ludwig took them into service and taught them how to deal with beast. They aren't weareolves, though one could argue what's the difference, in this world they are never referred to as such. That are feral people over taken by a curse. Some more tha. Others and it's not a dead soul possession. Though there are souls within the blood, it's not a spirit that has taken them and turned them in to beast. They were trying to escape a curse possibly being hollows they took the dead gods blood into themselves. It seems to me that gascoigne came from londo or lothoric as a memeber of the black hand in search of a cure. He wasnt a wear wolf.
