Divinity II: Ego Draconis

Set in the world of Rivellon of Divine Divinity, you play as a Dragon Slayer, who, after finishing your training, will obtain draconic powers to allow you to battle the last remaining dragons. As the training nears its end, news of a dragon spotted nearby forces you to investigate. 

In Divinity II, players can be not only a Dragon Slayer, but a Dragon themselves, and use draconic powers to fight a thousand enemies - all in a classic role-playing game format.
