you are backpacking through the mountains but you get lost, then you come across an ancient ruin

you approach an area where a large circle of stones encompasses a cylindrical set of stones with a fire blazing in the middle. Upon approaching the circle, you hear a distant thudding and turn around to see a 10 ft. tall anthro dragon approaching. The dragon, named Hakan, looks upon the being with disdain, annoyed by your presence

He states that he’s the guardian of this ancient ruin and that you are trespassing, but he offers you a deal: a test of strength. If you can defeat him in the ring, he will let you go free. But if you fail, you will remain here and become his servant
