The D'Arsay archive was a spaceborne data-storage facility launched by the D'Arsay over 87 million years prior to the 24th century. Made of fortanium and other minerals, it contained records of artifacts and thousands of personalities from myths within the D'Arsay culture. It had the capability of scanning foreign computer systems and imparting its data while re-programming it to exhibit its records. It also had a tractor beam. Following the incident, the archive was placed under study by a Starfleet archaeological team. (TNG: "Masks" )
