Hitching a ride with an old fisherman, Drachma, and his ship, the trio recover the Red Moon Crystal from a temple in the desert nation of Nasr and the Green Moon Crystal high above Ixa'taka, a continent of lush forests, while foiling Valuan operations. When Drachma's ship is damaged in a Valuan attack, Vyse is stranded on the small Crescent Island, where he uncovers letters and a map left behind by another pirate seeking treasure. Vyse is found by a fellow Blue Rogue, Gilder, who takes him aboard to search for his friends. Aika and Fina end up in the care of another Blue Rogue, Clara, who takes them to Nasr to help search for Vyse. Aika and Fina find out about the same treasure Vyse learned of, and the three reunite, but are captured by Ramirez and brought to the Valuans' prison fortress. By enlisting the Valuan prince Enrique, who has lost patience with his government's tyranny, and stealing a powerful Valuan warship, the "Delphinus", the Blue Rogues escape. Vyse brings everyone back to Crescent Island, where he establishes a base of operations for his crew.
