Thread Actually, the aedra and daedra are about equal in power, both being et'ada (Lorkhan is likely classified neither aedra/daedra and hardly et'ada, but tends more to aedra for being responsible). The aedra just happened to store their power in the Mundus that they made. The Daedra did NOT give their power and thus are at full strength when you wander into Oblivion. Aetherius and Mundus are where the aedra have more of an advantage because they can access their stored power. Observe Akatosh banishing Mehrunes Dagon. Oblivion is where the daedra have the advantage because that is their planes, bodies, and stored power. The only fair place would be the void, but to quote someone else, "Sithis would be like GTFO noobs", so there's no chance to ever resolve this debate unless Bethesda steps in with an exact list or chart of et'ada power levels.
