Thorax's dragon tail

had this idea for a story where Thorax goes to the dragon lands for more assertiveness training with Ember. To give him the whole "rough and tough" dragon experience, he decides to spend his visit as a dragon. Now, Ember has to help her friend while simultaneously making sure he doesn't get hurt during this whole ordeal. what's up with Thorax and his fascination for sticking his head into fire anyway?!
