King Mechagon was the ruler of the ancient city of Mechagon. He ruled as the last king of the gnomes who went on an expedition to discover the mysterious land of technology known as Mechagon Island. His legend faded into history until the fabled discovery of the Forgotten Vault in Kul Tiras.
His vision was to turn the denizens of Mechagon, and the rest of the world, away from the Curse of Flesh. The Rustbolt Resistance overthrew King Mechagon with the help of the champions of Azeroth.
