stone. While Link determines how to save Tetra, Oshus reveals that he is the Ocean King and that he and Ciela had to change their appearances to hide from Bellum, a life-eating monster that Link must destroy to save Tetra. Oshus also mentions that Bellum was the one who created the Ghost Ship and turned Tetra into a statue, and that he has taken residence deep in the Temple of the Ocean King. Linebeck quickly readies to abandon their quest, outraged at the lack of treasure to be found. However, his loyalties instantly return when Oshus promises the captain one wish in return for his continued aid. To defeat Bellum, Link learns that he must forge the Phantom Sword from three unique, "pure" metals located on nearby islands; Crimsonine (Goron Island), Azurine (Isle of Frost) and Aquanine (Isle of Ruins). After collecting and using the metals to forge the Phantom Sword, Link descends to the bottom level of the Temple of the Ocean King to face Bellum. After intense fighting, Link appears to defeat Bellum, and Tetra is freed from stone. After Link and Tetra hurry back to the S.S. Linebeck to find Oshus, Bellum emerges and sinks the ship, capturing Tetra and knocking Link unconscious in the process. Linebeck finally shows some devotion when he fights off Bellum while Link wakes up. Then, Linebeck gets possessed by Bellum, forcing Link to fight him, eventually defeating Bellum for good, saving Tetra and Linebeck, and releasing the sand from the Phantom Hourglass back into the sea. Oshus, now in his true form as a white whale, readies to depart with the three spirits, while Linebeck, surprising everyone, wishes not for treasure but for his ship back, and Tetra and Link teleport back onto Tetra's pirate ship, where its crew tells them that only ten minutes had passed since the pair left the ship, insisting that their journey was a dream. However, Link still possesses the now-empty Phantom Hourglass, and sees Linebeck's ship on the horizon, knowing that his adventure was real. Development Development started in May 2004, at which point the game still had gameplay similar to Four Swords Adventures. At a press conference in Japan for the Nintendo DS in October, Shigeru Miyamoto of Nintendo said that they were thinking of bringing Four Swords to the DS, which was later confirmed by Eiji Aonuma at E3 2005.
