So, I'm aware that NPC's can sometimes find out you stole from them(even if no one saw you), and will send some thugs after you, Shortly after arriving in Riverwood, and completing only the Faendal quest, I waited outside the smith because it was night time and I wanted the store to open. To my surprise, at the end of the waiting period, three thugs who seriously outclassed me wetre standing there waiting to kill me. After four deaths and reloads, I was finally able to defeat them by separating them and running away, alerting Faendal, and letting him take them out with his bow, while I used flames on them one at a time. When I read the note, I saw that "Moira" Hired them? I've since learned
Spoiler that she's a hagraven and part of the hangover quest.
I certainly had nothing to do with her before this. Wtf?
