It's of a faerie riding a dragon BUT-- he's missing part of his tail and she's missing a wing. The chain around him is broken. What if they were both slaves and helped each other to escape? And then after requiring a witch that they must find in order to help disguise themselves as mortals. Perhaps they both want to find their way home and even though they do not like each other at first (faerie's are flighty and dragons are hard-headed), they come to lean on each other and call the other friend.
