Wizards, Dragons, and Princes oh Natsu

Three stories in one, so pay attention. Warning, there will be some fluff in second chapter. If you haven't gotten past the S class trials, don't read this. Summary: Natsu has a few secrets... some he doesn't even remember he has. Like a history with Zeref, some dragon stuff, and of coarse knowing royalty. Will Natsu have to turn his back on human kind? Does he even have a choice?
