Somewhere near Ivarstead (I think), I strolled into a bandit encampment. I was instantly attacked by 2 bandits. These guys were no ordinary bandits, they has a much higher level than me.
So I'm instantly taking a lot of damage, and just as one of those bandits is about to give me his "coup de grace", I swear, a wild bear jumps out of the woods and destroys the two bandits in a matter of seconds.
Confused by what just happened, I just stood there looking in total shock. The bear then turned to me and attacked. I didn't stand a chance

That was an awesome random moment.
