The Dragon Heirs

Intro Update: you can now find this story on the Aidungeon app, it works so much better there. You're the unfortunate Elf Lord/Lady that your king has chosen to use to secure lasting peace between the elves and dragons. You've just arrived at the kingdom of Dragonia, and need to choosen your spouse. On the left is Grayson, in the center is Tristan, and on your right is Sebastian. They are the children of the Dragon Queen standing behind them. You are to meet and choose one of them as to be your spouse. Whom you choose will also inherit the Dragon Throne. All three of these possible choices is a Royal Dragon capable of polymorphism. They can look humanish, or take a full dragon form, or something in between with characteristics of both.
