And as someone pointed out on the forums, "worm" is another word for "Dragon", so it probably means they made peace with the believers in Akatosh and the rest of the Nine.
I was a little surprised when MK said the Nords didn't react with xenophobia, but I like the idea that they would show hospitality to the refugees. When you think about it, a lot of traditional cultures in our world also have a great regard for hospitality.
I was the one that pointed out the worm part, but it was not because of Akatosh and the Nine, far from it, that's Cyrodiilic beliefs. I was more inclined to say it was making peace with Shor-through-the-nords, because the nords, while sharing similar gods in Skyrim, do not worship nine. Instead, they worship Shor (Lorkhan) and believe Alduin (Akathosh) is a stark raving mad devourer but also a creator.
However, the
Dunmer are not fleeing to Skyrim, only Solstheim and the Skaal (the local nords of Solstheim) have a different belief system. They do not really revere Shor, as he is the Greedy Man in their myths. Instead, they worship a version of Anuiel as the All-Maker.
I'd go further, but I have stuff to do
