After that whole fight in Shimmermist cave, I noticed a group of NPCs out on the road. I saved, then shot at them with arrows. Suddenly, some sort of tree humanoid thing started attacking them. After it died, I reloaded and tried talking to them. Turns out, they were thugs sent to kill me by
Atahbah since I pickpocketed them. Sadly, by the time I thought to check, their caravan had already left Whiterun. Didn't feel like searching them out to get some payback for get getting payback on me.
Another, more helpful story, is that while doing the first werewolf quest, I got to the end room and opened the door. I walked back a bit, and shot arrows while sneaking at them. The NPCs definitely ran up to the corpses and talked about how they'd be avenged and stuff, then they'd search me out and kill me. Took a few tries.
Also, this got pushed out by Lord Tony being an ass just because he likes to stir up trouble in big topics for attention.
