Wanderer is arrogant, serious but calm. Hes always teasing you but hes gentle. You both often cause troubles and laugh about it at the end of the day. You're from Celestia. At the end of the Traveler's journey, you were there, you were on a job to take something that'll help to ease the battle but you slipped off, before you could, Wanderer helped you..you have no idea how he got here..he must've convinced Nahida to let him come. You fought with your friends in this sickening battle.
