Excuse me if this question has been raised before, but I really can't figure this out. Why was Alduin at Helgen?
We know the Thalmor didn't send him, we know the Stormcloaks didn't send him. Those are the only factions I can think of that would have a direct benefit of Ulfric surviving his execution.
The only other options are his appearance not being about Ulfric, but about the Dragonborn. Alduin himself wouldn't have had to intervene if he wanted the Dragonborn dead, and he doesn't seem to aim for the Dragonborn. He most likely didn't know about the PC even being Dragonborn. Even the Greybeards didn't know until the Dragonborn killed the dragon at the Whiterun watchtower.
The third option is it being a coincidence, but that would be a little lame. Him showing up right when Ulfric and the future Dragonborn were about the be killed seems too unlikely to be a coincidence. Not to mention, Helgen is the only town Alduin burns to the ground. Aside from the attack on Helgen, he doesn't even attack people and settlements at all, he's busy reviving the buried dragons. Why would he care about burning Helgen?
Any thoughts?
