on the GameCube is in the east on the Wii. The display is mirrored in order to make Link right-handed to make use of the Wii Remote feel more natural for the majority of players. The game chronicles the struggle of a young adult Link to confront the troubles of the "Twilight Realm", a mysterious force that appears around and interacts with Hyrule. When he enters this realm, he is transformed into a wolf, and loses the ability to use his sword, shield or other items, but gains other abilities such as sharpened senses from his new form. Twilight Princess includes an incarnation of Link's horse, Epona, for fast transportation, and features mounted battle scenarios including boss battles that were not seen in previous games. Twilight Princess diverted from the cel-shading of Wind Waker, integrating graphics featuring more detailed textures, giving the game a darker atmosphere. The Legend of Zelda: Twilight Princess HD released for Wii U in 2016. At 2006 Game Developers Conference, a new title Phantom Hourglass for the Nintendo DS was shown. It revealed traditional top-down Zelda gameplay optimised for the DS's features, with a cel-shaded 3D graphical style similar to The Wind Waker for Gamecube. The game is a direct sequel to The Wind Waker. Phantom Hourglass was released in June 2007, for Japan and October for North America and Europe. It was later released on the Wii U Virtual Console. The next Legend of Zelda for the DS, The Legend of Zelda: Spirit Tracks, was released in December 2009. In this game, the "spirit tracks", railroads which chain an ancient evil, are disappearing from Hyrule. Zelda and Link go to the 'Spirit Tower' (the ethereal point of convergence for the tracks) to find out why, but villains steal Zelda's body for the resurrection of the Demon King. Rendered disembodied, Zelda is left a spirit, and only Link (and a certain few sages) can see her. Together they go on a quest to restore the spirit tracks, defeat the Demon King, and return Zelda to her body. Using a modified engine of that used in Phantom Hourglass, the notably new feature in this game is that the Phantom Guardians seen in Phantom Hourglass are, through a series of events, periodically controllable. It was the first time in the series that both Link and Zelda work together on the quest. It was later released on the Wii
