If I were going to do that, I would probably have Meridia turncoat, and side with the Aedra in a war against an Undead incursion. I always saw the possibilities of Necromancy, set your army against theirs, and raise the fallen in the melee' until they were fighting their ex-allies, and eventually there would be no one left but zombies. The question is, which Daedric Prince would most likely be the power behind the Necromancers? Possibly Molag Bal, or Boethia playing puppetmaster to the Necromancers with a secret motive (To be revealed toward the end by the hero, of course) would fit the bill? I sure wish they'd fix the problem with not having enough bodies on the field for a realistic massed battle, but the ESOL engine shows promise in this regard. It might break the Radiant engine outright to do it the way I have it envisioned.
