So i was exploring the Eastmarch area of Skyrim and I came across an Imperial Legion camp in the mountains. I think it was named Eastmarch Imperial Camp or something. Anywho they got angry after i walked into their camp and all gang attacked me; I didn't really care all that much because I'd already joined the stormcloaks so I wanted to kill them anyway. I'm a lv 19 mage right now and easily dispatched them with some Atronach and expert destruction spell... At least I thought I dispatched them. This one legionare guy just keeps getting up after I kill him. It's really annoying. I think he's a quest character or something and it's really annoying. How do I kill this guy because I don't want to do his quest?
