I keep seeing this argument a lot, but have yet to really understand it. He's the Dragon God of Time, just with a new name and shiny new pro-Man bias. I think you've said in another thread today that the Marukhati didn't really do anything to him, b/c Akatosh is just another way of looking at Auriel, but I always felt that they did do something (else, why have the Dragon break for so long?). This is getting sidetracked from my main point, though...
It shouldn't matter WHEN Akatosh is created, the exact same as it doesn't matter WHEN the Tribunal ascended. They made it so they always were, which means they never weren't. It reminds me of something I read, once, let me see if I can find it...
Whoa, what. No you're thinking way too complex. We've had the obscure text version, http://www.imperial-library.info/content/shezarr-and-eight-divines for a long time now. It first appeared in Knights of the Nine as http://www.imperial-library.info/content/shezarr-and-eight-divines. No need to bring in the whole Selective.
The relevant bit:
"This slavery lasts for generations. The isolated humans eventually begin to venerate the pantheon of their masters, or at least assimilate so much of High Elven religious practices into their native traditions that the two become indistinguishable."
"Akatosh [that is Auri-El - Prow] was an Aldmeri god, and Alessia's subjects were as-yet unwilling to renounce their worship of the Elven pantheon. She found herself in a very sensitive political situation. She needed to keep the Nords as her allies, but they were (at that time) fiercely opposed to any adoration of Elven deities. On the other hand, she could not force her subjects to revert back to the Nordic pantheon, for fear of another revolution. Therefore, concessions were made and Empress Alessia instituted a new religion: the Eight Divines, an elegant, well-researched synthesis of both pantheons, Nordic and Aldmeri."
