Interesting. Is that accurate?
Yes, I would say its accurate depiction of the aurbis, to the degree a two dimensional representation of infinite spheres nestled in infinite spheres can be.
Nirn in the middle, surrounded by the moons and planets, stars and sun.
Oblivion which holds the Daedric realms surrounding that.
Aetherius (which is linked to the sun) surrounding that.
There are also what is known as 'outer realms' and 'void stars' but I dont think its known where they should be placed.
What I am missing is the Is and the Is-Not, the Padomay and Anu, that should lie beyond the aurbis, and the aurbis itself being the place where these two intersect.
