Arion is the elf you meet in the West with his sister Noira. They're the children of Celestine, Elis aunt.
He's not. Unless you're referring to the Green Path. Then I have no clue because I didn't find that path interesting enough to make pass the trip to the west.
Oh, I remember now. The elven queen sisters are cursed by fate; they are reflections of each other. It could be that when the king came to marry the queen, he had a son and a daughter with her sister, but only took the queen away.
