User blog comment:Madman97/The Aedra Vs. The Daedra theory/@comment-7153552-20131009223138

I lack the time or energy, at this moment, to make too many rebuttles or confirming statements so I shall keep it to this one that comes to mind most prominently;

You said that the Aedra have defeated the Deadra on several different occassions, and even note Akatosh bringing down Dagon. I do not doubt the power of the Aedra, but it should be noted that Akatosh didn't directly bring down Dagon. Martin Septim became the avatar of Akatosh, the Aedra needed a mortal to champion him. The Aedra needing champions is further backed in the Knights of the Nine questline. If they could defeat the Deadra, surely the ghost of some long-dead villian wouldn't be a problem, why need a champion to take on your cause?

We could argue all day about the moral needs of the Aedra to take on champions, and I'll agree that it makes mortals better people and that sometimes a non-direct approach is better all around (you got to both take down the bad guy and rebuild the Knights of the Nine, win/win). However, the point remains that a champion was needed and used. The Aedra may be the essence of creation and not change, but they use mortals just as much - granted for better causes - as the Deadra.
