I want oath of conquest, and oath of glory. Conquest is the only straight up evil subclass option that doesn't involve oathbreaking, and glory is a really solid neutral subclass that I think could satisfy people looking for such a thing.
Watcher is really nice, and relevant to the story we are caught in too, but it might be hard to play with considering the events of this first act. Accepting tadpole powers, allowing the absolute cultists to continue or joining them, accepting help from Ethel, or Omeluum, all these would immediately go against the tenets of your oath.
