Ziggurat Industries is a corporation in the Xenosaga universe that specialized in cybernetic and bio-mechanical technology.
It was this company that created the Life Recycling Act-era Ziggurat series cyborgs, of which there were only eight. Ziggurat 8, also known as "Ziggy" and Jan Sauer was the corporation's last produced cyborg model. After a dwindling pool of cyborg body donors, the replacement of lost tissue in accident victims and other critical patients being taken over by procedures incorporating Realian technology (formerly covered by cyborg surgery), as well as the passing of the Species Preservation Act by the Galaxy Federation Parliament, which repealed the Life Recycling Act, Ziggurat Industries could no longer legally produce cyborgs, or at the very least reanimated corpses for use as cyborgs like Ziggurat 8.
With cyborg technology no longer profitable Ziggurat Industries shifted its focus to the upcoming field of nanotechnology, with a special commitment to nanomaterials research. It has made major contributions to science and health care, including the refinement of highly conductive, durable materials and the development of medicines that suppress the proliferation of dangerous viruses.
"Ziggurat" is a reference to the ziggurats that once stood in Babylon, which is now a part of modern-day Iraq.
