This paladin subclass was inspired by the great wyrms themselves and a game my buddy played that let you become a dragon. Oath of the Dragon Paladins have sworn their allegience to one of the great dragon gods which does effect how their abilities work on the small scale.
Mechanically you can sharpen your visison and exhale a breath weapon with your Channel Divinity. Have a changing Aura of elemental resistance and Manifest aspects of the dragon such as wings, scales and claws to give your self a boost out of combat. The final ability (kinda spoiled in the first line of this discription) allows you to become a dragon for a limited amount of time and strike terror into your foes, because whats scarier than a dragon a dragon that can Smite.
