Wait, what? Was Akatosh not the first/one of the earliest aedra?
If I remember right, his creation of time helped the other spirits gain structure and form more easily.
Is Akatosh not the oldest being (or possibly dead being) around?
Akatosh was a creation of Alessia, who was later given form when the selective tore him from Auri-el and caused a Dragonbreak.
The dragon-god of time was the first spirit, but Akatosh was not the first dragon-god of time.
