Hailing from Germany, Faust I is the main character of the renowned German tale, "The Tragedy of Doctor Faustus". As a man who was so consumed by lust for all the pleasures of the world, Faustus made a deal with the devil to gain them. For necromancy skills, the Devil (more commonly known as Mephistopheles in Faust literature) also granted Faustus youth and riches. In the end, Faustus died a terrible death when Mephistopheles came to claim his soul at the end of the seven year contract.
