When you become a werewolf you are told that after death you will be going to Hircines hunting grounds. Yet when you become a nighting gale and after you die, you are forced to go to Nocturnals domain and serve her for eternity.
That being said, what if you are both? What do the 2 Daedric princes share you or something? I don't see em fighting over you lol. Like seriously, what do you all think would happen?
Well you could potentially swear fealty to all the Daedric Gods. I don't think they care enough to fight over you, they would probably gang up and torment you for all eternity.
You could argue that the aspect of you being a werewolf would go to Hircine, while the other being a Nightingale would go to Nocturnal. I mean, I don't know much about TES lore, but the fracturing of your soul isn't that out of the question, right? Both of those entities would exist in two separate realms of existence, after all.
