Vah Rudania

Vah Rudania is a mechanical construct in The Legend of Zelda: Breath of the Wild. It is one of the four Divine Beasts. It serves as one of the main dungeons.

History
100 years before the events of Breath of the Wild, Rhoam Bosphoramus Hyrule, his daughter, along with four other champions sought to seal Ganon through the use of the Divine Beasts and Guardians. Ganon retaliated by taking control of Vah Rudania and the other Divine Beasts, turning them against the people of Hyrule. Daruk the Goron Champion who was in charge of controlling Vah Rudania met his demise by a creation of Ganon known as Waterblight Ganon, who then assumed control of Vah Rudania for the next 100 years.
