What he means by the "wheel" is the Aurbis. Basically picture a 2 dimensional circle with a three little circles inside of it. The smallest is Nirn, than the border of Mundus and Oblivion, than the border of Oblivion and Atherius. The largest one is the border of Aurbis, which is basically the universe. Outside is the void, or Padomey. Sithis, who is basically the devil, is the only thing out there. He's just been sitting there doing who knows what since the dawn of time.
