XD you remember my explanation for it right? It's not that he is an elf but rather his people are thought of as elves since their culture is so vastly different than the rest of the world and few Opradans ever climb the mountain to interact or trade with the world. They are nimble and quick especially in trees and rough terrain, and as a hunting culture most of them are great archers. Seeing an Opradan outside of their country is rare so it is commonly thought that the country is a country of elves.
