The circle is the Wheel
The Hub of the Wheel is the Mundus
The spokes that bind the wheel are the Aedra
The voids between the spoke number sixteen and are the Daedra
the Tower is the I that sees the Wheel sideways
The wheel turns,
the dragon eats.
So.. we have moved on exactly nothing besided establishing that I am more deeply rooted in lore while you are in history.
Your quotes are definitely from deep in something dark but it's not lore. Those quotes are from no established lore and the source those quotes come from has so many holes in it that it might as well be swiss cheese. They could have a circular border, but it makes more sense that the forces of change and stasis merged and the chaos that formed was Sithis. Frankly, it also doesn't that if Alduin is Akatosh that he would be one to end the world and reform it, seeing as how he is an et'ada of Anu, he would do everything in his power to keep Mundus constant instead of trying to destroy it. Also, you made a comment that Mundus was linear on the inside and the wheel was cyclical on the outside. Well wouldn't the inside of Mundus only be bound by the linear time instead of the cyclical time?
Uggh I just had an image of two spheres of force having six. How dare non-sentient forces have six!
