Akatosh is a de-clawed Au-Riel? Akatosh and Au-Riel are one and the same. It is just the name given to him by two different races. I think the Men of Tamriel like to think he's on their side now, but I think they are gravely mistaken.
Auriel was broken by the selective, time itself was smashed, and the elven parts of Akatosh were removed. Thats what I think he means by Akatosh being a de-clawed Auriel.
I think many people are taking the books of Skyrim too literally. They're books, opinions, propoganda, but not facts. Definately not facts. Paticularly those that relate to creation.
Oh, I was looking through some old posts I wrote back in Oblivion time and came across this, which may or may not be relevent
Everything begins with three, Nirn, Anu and Padomey
Nirn became Kyne, Anu became Ariel, Padomy became Lorkhan
Kyne became Kyneath, Ariel became Akatosh, Lorkhan became Shezzar
*Akatosh became Tiber Septim, Shezzar became the Underking*
Martin Septim became Akatosh, and vanished from the world, tipping the power back into Shezzar's favour
Akatosh represents status, the monarchy, order
Shezzar represents change, freedom,
Akatosh represents the Past, the Empire
Shezzar represents the Future, the Intenigrum
it is a cyclical motion, in the chaos of Intenigrum it is Shezzar who is powerful, with the order of empire, it is Akatosh who is powerful
