How about Morag tongs? I would like DB and MT duke it out in the freezing tundra's, a pacifist group who doesn't like war not because of peace but because of business hindrances versus a separatist purist group who kills just because of patron.
They are both in ruins,The Morag Tong have probably lost their political edge with Vivec's disappearence and The DB has anywhere between 2 to 4 living members left. It won't be much of a fight.
Make werewolve more sneaky, and add werebear lycanthropy, for real men (even though, in real life, bears rely on stealth more than most wolves) Mages have vampires
