The Linebeck Island is a location from The Legend of Zelda: Breath of the Wild. It is a small island located in the Lanayru Wetlands region. Located nearby are Mercay Island and Bannan Island, all of which share names with locations from The Legend of Zelda: Phantom Hourglass. A sunken Treasure Chest can be found nearby the island and uncovered using the Magnesis Rune. A hidden Korok can be found here to obtain a Korok Seed.
Like many locations in Breath of the Wild, Linebeck Island is named after a character from a previous game, namely Linebeck which fits with the locations named after islands from Phantom Hourglass as Linebeck was a main character and ally to the Hero of Winds in Phantom Hourglass. Additionally Linebeck is said to have became a legendary captain and seafarer in both Spirit Tracks and Tri Force Heroes indicating it may have been named after the legendary sea captain.
