also...does Seven flights have to do with anything? has Alduin completed this proccess seven times?
I couldn't tell you...but I think dragons have a thing for seven.
The quest will have us find the eighth dragonball, and using its power to locate the other seven, and thus consume the dragonballs and become a equal to Alduin.
{Insert epic battle scene in an alternate plane}
After the battle, we seal Alduin into the seven dragonballs, and they scatter across the globe. The eighth however stays with the player, giving them the ability to learn one epic time based shout. A legend is born that whomever can find the seven dragonballs is allowed to make one wish...
...and then years later a space pod lands, and some old guy drops the baby inside on its head...
I've solved it!
But really, I'm not sure what Beth has in store for us. The civil war has to come in to play somehow, otherwise there wouldn't be a reason to have it in the first place. And killing the God of Time probably isn't the best idea. Other than that, its up in the air.
