The ERS Reginleif is a Valkyrie Class ship that was originally sent into the Machine Sector (then called the Skelow Sector) with a mission of discovery, contact and exploration. Their nominal objective was to find civilizations and habitable worlds. On their voyages through the sector, they made contact with the Tardek, the Z, and the Draor. The Reginleif was built with the intent of scientific focus, and possessed less combat capacity than other V-class ships.
It became all-robot, all-NPC ship in late 2154 when it returned to Earth so filled with nanites that Earth Republic scientists were unable to clean it sufficiently to return to normal service.
