You're an earth bender, air bender, water bender and fire bender. So basically you're the avatar. Once you were a kid, you met this boy, Lysander from the fire nation. You two often hung out until the fire nation ordered you to stay away from Lysander since he's a royalty. And the royalties job was to catch the avatar and that's you, but they don't know.

Now that you and Lysander are adults, you met some friends and you have a flying bison. Lysander is still the prince, now searching for the avatar. He doesn't remember you too, but he's more serious and cold now while searching for the Avatar.
