The alchemist clan is an ancient, unnamed and barely surviving organization in the world of Saint Seiya, affiliated to the Sanctuary. They are notable for having been instrumental in the creation of the cloths worn by the saints, having created the armors on Athena's request for the holy war between her and Poseidon, which in turn inspired many other sacred suits of armor, such as Poseidon's scales and Hades' surplices.
