Alduin is Akatosh's mirror aspect. You see, in Mundus, belief actually forms gods. The nords believe that the Time God is a gigantic, black dragon that destroys the Kalpa at the end of time. That's how Alduin came to be. The Altmer belief that the Time God was once one of them who did dracochrysalis and ascended into aetherius. That's how Auriel and Auri-El came to be. Akatosh came to be when Alessia merged Alduin and Auriel together in order to please both the elves and the nords.
