guys, the reason i asked this qwestion was because i was curious as to whether or not there is a higher power in the elder scrolls universe than aedra and daedra. my guess is that when it talks about exceeding the gods, bethesda is referring to itself in third-person because they did create the elder scrolls. therefore they exceed the aedra and daedra because they created them. if it is not referring to bethesda in "the pension of the ancestor moths", i am curious as to what power could be higher than the gods? this is the only explanation i could come up with. perhaps it is a qwestion that will never be answered.
I would say the Magna'Ge is "stronger" than the Aedra and the Daedra, for they are free from boundaries. But they also, from what we know, lack any way to express their "power", or anything to exert their "power" on, so in reality, they are also weaker than the Aedra and the Daedra.
Anu and Padomay could also be considered "stronger" than the gods, but they are not self concious in the same way and thus they also lack real power.
There is also the God-head, of who's dreams all things TES are made. The God-Head is the "creator" of all things, because they are all in his head. One could say he wrote the Elder Scrolls, because he is dreaming up the stories which are told in the games.
However, I think that, maybe, the expression (that the writings exceed the aedra/daedra) should not be taken litterary. It's just means they're very important.
