History[]
On stardate 54642.8 (2377), a hitherto secret Cardassian fleet destroyed the Federation main reserve fleet, stationed at Starbase 109 in the Pearl Nebula. With Starfleet otherwise occupied, it fell to the Klingons to defeat the Cardassian uprising. Chancellor Martok himself came to the Zarush system. The IKS Sword of Kahless, flagship of the Empire, boarded the derelict Starfleet facilities and ships, and led the defense of Zarush against further Cardassian attacks.
