I was playing at 2 in the morning, in the windfall mod(fcom added). I entered some creepy undead dungeon, got totally freaked out by this bone baby things(Sleeping pills might have contributed a wee bit to the freakout) throwing fireballs at me so I ran away. As I was running down the road at full speed I see a guard in the distance, not Imperial legion. So being as freaked as I was, I took out my bow, put two in his chest and pretended I was in grand theft auto. I really wanted that horse to put some distance between me and those bone baby critters.
Also, I apparently killed some guard as part of a windfall quest. I don't really recall that at all though.
