Shogun Sanctuary
The Sanctuary of Light was built on Mount Fuji in Honshu, Japan by the Followers of the Light who were on Earth to destroy their ancient foe Maur-Kon. They created three robots and selected three pilots to become the Shogun Warriors to face the menace of Maur-Kon and other threats to the Earth. Eventually Maur-Kon got revenge against the Followers, slaying them all and destroying their Sanctuary. Subsequently the Shogun Warriors brought Maur-Kon to justice.
Later, the ruins of the Sanctuary were discovered by adventurer William McLaughlin who uncovered a fourth unfinished robot in the wreckage. He finished building it and dubbed the robot the Samurai Destroyer. He used it for a series of high scale robberies and stored his stolen loot in the ruined Sanctuary, until he was ultimately stopped the Shogun Warriors and the Fantastic Four.
