Kol's ship
Kol's ship was a Klingon  warship in the 2250s. This ship was commanded by  of the House Kor. 

In November 2256, this ship visited the grave of wrecked Starfleet and Klingon starships in an unspecified binary star system, where it rendezvoused with the Sarcophagus. Using provisions from the ship's stores, Kol convinced the crew of the larger starship into joining his house. Kol, then, transferred his command to this ship. ()
