Along with Abend, the two were to accidentally die out at sea, while on a trip to Peshi. Allowing Schnee the ability to live free of her royal duties. Abend told this to his friend and loyal follower, Nino's father, that he was going to Badon and was going to live there. Nino's father decided to follow him. After making their way to Bãdon, Schnee released Abend of his duties and the two went their separate paths.
