So, I know if I kill an orc in a stronghold, they'll be hostile. However, I haven't killed any orcs except for one on a road near Markarth that was doing that whole "milk drinker" random encounter. I doubt paying The Steel Heart's dowry and leaving with her would be a problem.
Anyone have any ideas on how to fix this? I really wanted to train my block and pickpocket off Larak. If not I guess I'll just join the companions for Nadja -_-.
