With my last character, I have run into Tsalgar quite frequently. On the road, he seems to be rather pleasant, bluff and hearty. However, 9 times out of 10, he's in a fight with somebody or something.
Anyways: At a certain point, I ran into him at the inn/tavern in windhelm. For reasons beyond my understanding, he all of a sudden picked a fight with EVERYONE in the inn! I left because I didn't want any part of it.
Next time I met him was on the road, and everything was back to normal.
Then I met him later on, while I was strolling down the road to Markarth. For absolutely no reason whatsoever, HE ATTACKS ME.
So I killed him. Got some decent loot from his shattered corpse, too. Wandering Wierdo....
Is there some secret story behind this guy? Is he actually a free-roaming Skyrim version of Norman Bates? Clearly the man is not playing with a full deck.
