Some dude created Nirn.... This dude died. And his friend left with some friends, creating the sun and stars.
And that's where my understanding of Mundus history dies.
When does the remaining Aedra decided to come down to Nirn. Who were them? Who stayed in Aetherius?
I now about the war between the wonderer Ehlnofey and the Old by the way.
PS: Am i the only one who thinks that TES Lore needs a book or a game?
