Mine was me, a ranger nord about level 13 (also a Stormcloak) running up to an imperial camp (in Hjaalmarch or Winterhold I can't remember) to kill them all. So an imperial sees me and draws his bow and I think as I shoot him "his aim seemed to be way off, was he even aiming for me?" Then I got my answer. A roar. I turn around and there's a frost dragon (the first I had encountered). So I ran for the imperial camp thinking maybe they could help (even though I killed one of them, there AI makes dragons a higher priority then me. After that there was a lot of chaos, even some Stoarmcloaks from a nearby camp rushed in! It was pretty epic with about 20 or so guys fight a powerful (at that level) dragon! Oh yeah but I was hunkered down in the healing tent most of the time grabbing potions to survive! The most epic part was probably when the dragon LANDED on the tent I was in, and started shouting ice every where!
So that's my story. What's yours?
