Lorkhan convinced the Aedra to create Mundas, right. Upon the creation The Daedra destroyed Lorkhan splitting his essence between Tamriel and the moons. This essence birthed man and mer, correct ?
Lorkhan convinced or tricked Et'Ada to participate in creation.
When the scope of the project became clear, that they would have to sacrifice themselves wholly or partially into the project, the Magna-Ge left.
The Aedra are the ones that stayed and continued.
The Daedra are the ones that never participated, but like to stick around and meddle.
At Convention the most powerful Aedra assembled and punished Lorkhan.
His body was torn asunder and became the moons, his heart was hurled far away and where it landed a volcano erupted.
(Red Mountain).
Man and Mer are Ehlnofey. They are the Aedra that wholly dissolved into the project, fracturing into ever smaller entities.
From the perspective of man this is a good thing, it allows a transcendance and understanding that is beyond Aedric capability.
From the perpective of Mer this was a trap, and Lorkhan is their jailor.
Edit: To Bright: Read the links I provided, do some research.
TES lore is not bound solely to what appears in game. How would you classify the creators of the lore explaining themselves on the forum? Its obviously canon, as it is an explanation of what is in the game, but it does not appear in any in-game text.
That Talos is Lorkhan however can be inferred from many things, many pieces strewn throughout the games, but the most powerful indicator is repetition of story. As above, so below.
The Thalmor want to erase him so they can uncoil the dragon. What is time without space?
