Ooops, I had half-written a reply the other day, but got distracted.
The setting seems a little DnD-ish, as in I felt like there was a little prerequisite in understanding background happenings in the world that I wasn't really familiar with. Didn't really distract from the story, though. I rather like the idea of him stuck as a dragon, begrudgingly helping them out and finding out it's not all that great. It was a happy ending, which was good. And cool that he got the best of both worlds. However, I think it would have made for a stronger story if the solution to his problems didn't just fall into his lap like that.
Still, rather enjoyed this! You never fail to entertain. Looking forward to the next one.
