1500 years ago the Yin and Yang forces - Heylin and Elemental - were balanced. Why aren't they now? Blame those pesky Apprentices! Chase/Wuya/Dashi triangle implied.
- An interesting idea, if not entirely canon to the best of my knowledge.
You could use a good deal of improvement on basic english skills, but this is at least readable. You can spend a little more time on descriptives to just to give it a bit more of a sense of realness. I would have had a bit less confusion if you had mentioned who was which dragon only once or twice and then refered to the characters by their names.
