History[]
In the year 2409, Ambassador Kas represented the Klingons in the abortive peace negotiations with the Federation on Regulus IV. The diplomatic effort had been setup to fail by a rival of Kas's Great House, Admiral B'vat. When B'vat arrived in his Negh'Var-class flagship, Ambassador Kas returned to his battlecruiser and joined forces with a Starfleet starship defending Regulus IV. Together, they fought off B'vat's escorts and forced him to retreat. Kas's battlecruiser remained in orbit of the planet. (STO - Klingon War mission: "The Kuvah'Magh")
