Sure, we know the daedric princes. good ol' mehrunes dagon, molag bol, azura. all of these are known by most people, but princes like peryite are not so much known.
but is there daedric princes that nobody knows about? ones that have not been seen, either because they prefer not to mess with the mortals? or mabye they are trapped in an oblivion realm that cant be accessed by mortals. who knows?
so do we really know all the daedric princes? are there more of them out there in the realms of oblivion? and if so, why dont they meddle with the mortal world like most of the other princes we know?
so is there a chance that there are more daedric princes? i dont know, but if i had to bet, i would guess there are possibly many more. wouldnt you agree?
