I'm on a quest to find some artifacts for a guy named Avicenn. He wanted me to find Shine and Shadow. Well, I found them and not only are they artifacts but they are a pair of freakin' awesome daggers that are incredibly better then what I'm using. I don't want to just ignore the guy (mostly because I hate having unfinished quests in my log) but I really don't want to give them up.
When I return to Avicenn, is there an option for keeping them? Fight him? Pay him off?
