The abandoned factory site is a factory on Talvania that was created by the machine race. Since their disappearance, the site was abandoned, until the Space Pirates appeared. They used the site to conduct research on camouflaging technology, which they used to conceal the Doomseye.
In Metroid Prime: Federation Force, the titular Federation Force is deployed to this site during M13: Phantom. Their objective is to recover three Space Pirate data storage devices called Architects. The Force unwittingly activates the Architects, and are forced to chase them through the facility. The site is well guarded by Space Pirates, and the largest chamber (pictured to the right) has a cylinder in the center that releases Talvania Gas at regular intervals.
