I found myself in the middle of the Morkvarg quest without even realizing it's a side quest. I'm stuck at it, and the problem is, I cannot kill Morkvarg (my attacks don't do much to him, but 2-3 attacks from him kills me). I have been searching a little bit to find how to finish this quest; however, everything I have found so far includes killing Morkvarg, which I cannot do.
At this point I'm happy even to drop out of this quest and continue the game, but I don't know how to drop out of a quest (and doesn't seem like I have a saved version immediately before the quest started)
Any tip will be appreciated!
