Early on in my quest, Dryston would not stop fighting in a fist fight so I accidentally ended up killing him. Since then I have had to kill all Markarth guards I see, so my bounty is quite high...
I have now sided with the Stormcloaks against the Empire - And all the current side quests are in Markarth. Every single one. I am at level 48, so can survive until I go through a door or move to another area, and eventually I run out of potions/arrows/strength.
It doesn't appear that I can simply surrender myself, despite trying after reading this question - they always attack rather than try and imprison me. Not sure if this is because I have a follower and a dog - the dog especially is a bit aggressive.
Anything I can do without resorting to console commands? I'd rather not have to start again unless I have to.
