LOL. He should start with Valenwood because Bosmers are annoying.
Maybe he wants to save Valenwood for desert?
Well i think that since he is a god, one of the most ancient ones that helped create the world... he is in a way, physically formless. Unless he wants to make his presence know to the people of Nirn. Dont the gods chose their form as whatever they will? Didnt Lorkan create Nirn with his own form/body?
From what i gather, there are 2 great existences of form that existed before Nirn was created. 1 is status/potential and the other is change.
The gods who are left/tricked into creating Nirn are descendants of change. Imprisoned in this form of change. So if Alduin eats the world wouldn't that make him formless and return to status/potential?
Not a master of lore and prolly not correct in what i said but does this make any kind of sense anyone?
