Magnus was caught in the centre of Altars bounty hunters, these guys were tough, they had obviously been training to kill him and Shinlong for some time. He had taken care of half of them but he was to weak to deal with the rest. He spread his wings and took to the skies, he'ld made up his mind, he'ld go and find his brother and friends. If Amor or Mog needed him they knew where he'ld be.
