One question I have is why is it that people seem to focus in so much on belief-shaping-reality all of a sudden? In other settings (D&D, the aforementioned Mage, etc.), belief literally does control the gods, but in TES, the only quote I've found about the gods being "shaped" by any outside sources is from one in-game book's
theory that spirits that get more worship are more powerful, and this from MK:
Don't forget that gods can be shaped by the mythopoeic forces of the mantlers-- so Tosh Raka could be an Akaviri avatar of Akatosh with a grudge against his mirror-brother in Cyrodiil.
Just like Akatosh-as-we-usually-know-him could time-scheme against his mirror-brother of the Nords, Alduin, to keep the present kalpa-- perhaps his favorite-- from being eaten.
Notice all the coulds.
Don't get me wrong, I'm on-board with the Aedra being puppet-corpses, it adds a strangely dark undertone to the otherwise unfortunately bland representation they were given in Oblivion. But the MK post leads me to understand that it's the beings who "Walk Like Them" that end up shaping the gods, not the collective willpower of the Sleepers or somesuch. If there's a post or book that I've overlooked, pretty please point me in that direction, and I shall go off someplace quiet to read it.
