Invictus

The Invictus jumpship was the crown jewel of Emperor Taurelian's fleet.
In her day, the most powerful weapons platform the Empire had ever built - a world-killer.

The disappearance of the Invictus was some 700 years prior to Salvor Hardin 's capture by the Anacreon Grand Huntress, Phara Kaean . Hardin was captured circa 12,102 E.I.
