I was wondering; what are you going to do about Dain for the campaign? Are you going to make a young version of him, or use the old skin?
How many missions? Their wasn't much description about the battles in the war. Only that many of them took place in the mines. The only places I know that their should be a mission in are Mount Gundaband, a scared place to the Dwaves where Durin the Deathless was born, and Nanduhurion [Agarlond (spelling?)].
