We don't see any of them in Alagaësia, so presumably Angela got hers from outside.

Ah yes, from one of those foreign countries that don't exist. Not that Eragon was the least bit interested, of course.

Yep! I really don't care much for him in this part. I suppose that he eventually gets this attitude "fixed", but Paolini's method of doing that is not great, of course.

As usual, Morontagh and Thorn recover by... killing lots of people. Huzzah.

Given that he said it took him quite some time to acquire them, I think he bought them off people who stole them from the nomads, which would likely have included Dras-Leonan slavers. What a hero.

Headcanon accepted.

Are the Riders even viewed that badly now? I don't recall anything about Eragon or Arya getting trouble after the war just for being Riders.

All Riders are seen as automatically Good unless they're Galby or working for Galby and there is no such thing as redemption in Paolini Land.
