Hebra (ヘブラ Hebura?) is a location from The Legend of Zelda: Breath of the Wild. It is a province of Hyrule which includes the Hebra Mountains, Tabantha Frontier and Tabantha Tundra regions. As a mainly cold mountainous area, Link needs to bring cold resistance Elixirs or armor.
The name Hebra is a reference to the japanese version of The Legend of Zelda: A Link to the Past in which the Light World version of Death Mountain is known as Hebra Mountain as the name Death Mountain only applies to its Dark World equivalent in the japanese localization. Interestingly though Death Mountain exists in Eldin Breath of the Wild, both the Hebra Mountains in Hebra and Death Mountain in Eldin are on opposite sides of Hyrule and both are polar opposites as Death Mountain is extremely hot and volcanic while Hebra Mountains are snowy and extremely cold presumably referring the Light World Hebra Mountain and Dark World Death Mountain being opposites in the japanese localization of A Link to the Past.
