Gentleman Barracus:
As such he's going to be everyone's best friend! He'd be more than happy to help regain your various plot coupons.
Let's not retrieve them.
The theft put Baldin on the outs with his hold, but that frees him up to adventure. Barris doesn't want the texts, because they're only useful to someone seeking dark and worrisome power, who also understands runic magic. And there's every chance that whoever took the texts won't ever be able to find the runes to which they allude.
I mean, they probably will, of course, but getting the texts back won't prevent that.
I don't want to set up lame fetch quests, just backstory and potential rumblings of something that can blow up on us later.
