Hundreds of years ago, the dragons and humans came to an agreement. Since dragons liked to kidnap princesses and human knights liked saving princesses. They came to a deal that the Kings and Queens would ask the dragons for help. Certain dragons can sense different parts of a human's heart. A princess would say what kind of person she wishes to be married to and get sent to a dragon tower to wait for. Dragons are extremely powerful so they would only allow the humans they chose to pass. That way is not always perfect but all of the kingdoms have agreed to it all these years.
"They are planning on making the deal." Princess Anya told me as I was sweeping the stables.
She was sitting on a bale of hay while swinging her legs back and forth. I gave her a chair before, to keep her dresses cleaned, but she prefers to sit on the hay. At least she chose to wear a yellow dress today so the hay blends in.
