i dont mean to nitpick, but the economic stuff can be a minor subplot that is referred to every once in awhile. lets make sure we focus more on the "attempting to take down the overlord" bit. sure, the dragon is a banker (or whatever, i dont remember honestly), but its still a dragon and will be used in the traditional way dragons are used in stories: mounts and crazy killing machines. He can still sit on his mountain of gold, but when the overlord calls, he answers.
