Tiber Septim is, according to much of Tamriel, Talos. How he became a god, and if Talos is actually Tiber Septim, is a matter of much debate and speculation. This is yet another subject where I must assume Bethesda left the judgement up to the player.

I do not believe Tiber Septim is an Altmer as his aspect, Wulf, is an Imperial as I mentioned before. Besides, why would the Altmer outlaw the worship a god of their own kin and blood?

Again, it is not unlikely that this is yet another subject that Bethesda leaves to the player to decide what to believe.
