While other vessels owe their unique designs to endless iteration, fastidious research, or ingenuity, the Kos’Karii is unique in that its interesting design came about as an accident. During the Battle of Kaisu, while Sela’s forces bombarded the Klingon Imperial Fleet, a Bortas class vessel called Kor’Thau attempted to break the enemy’s line in order to rescue its trapped sister vessel. This risky maneuver resulted in the Kor’Thau losing the majority of its aft hull and the bulk of its neck, leaving it with a thin, jagged needle supporting its bridge. In the midst of battle, with no resources to spare, the crew managed to secure the remains of the ship’s neck with Dilithium pylons. It certainly was not a pretty sight, but it was sufficient to keep the vessel together on its return journey to Kronos. Oddly enough, the captain of the ship was rather proud of the reputation it garnered after this incident, as well as the somewhat eerie image the protruding spikes gave to the ship’s silhouette. He rechristened the vessel Kos’Karii, after the wraith-like eels that prowl the blood rivers of Fek'Ihri, and devoted his vessel and crew to the rescue and transport of wounded allies.
