Since you're here in Natha'vor, you might as well help out the rest of the pilgrimage with a problem.
These trolls have stolen several of our scrolls. Why they would, I have no idea, I doubt they're smart enough to even read.

Especially healing magic... which I'm sure Shoak is going to need when you rescue his dumb shell.
