In Bloodborne there are hunters that fight beasts. The Lady with the beak masks hunts hunters who turn into beasts themselves. The guy is Father Gascoigne. Who isnt called father because of religious purposes, he just has two daughters. the crow mask lady is ask to cook his two girls dinner because their father is turning into a beast, and the crow lady will have to kill him soon. It was kinda a final wishes kinda thing. Very sad
i think he's a foreigner who earned the title of "father" elsewhere. likely some kind of church outside of yharnam. and eilene wouldn't kill him if he turned into a beast, that would be a hunters job to kill a beast. eilene hunts hunters who have gone mad with blood lust, such as henryk, gascoigne's old partner.
Bloodborne had so many great characters and story lines but they were just too short. If nothing else, I think the game just needs some more stuff to do with all of the NPCs you find.
