Kuhrrat was a Klingon in charge of a miltary post of the Klingon Empire on Aquila 3. He attempted to help the crew of the USS Enterprise find a terrorist vessel in the Aquila system - he was an eyewitness to an apparent attack on the Asteroid C-21 Khulli base.
Previously, he had been the governor of the planet Cossina 3. According to Denning, during Kuhrrat's reign on Cossina 3, the planet ran low on gear lubicrant, and so Kuhrrat had some of the natives turned into gear lubicrant. Kuhrrat also referred to humans as "Earth creatures" and "Earthlings"; he had a disdain for what could be a lack of manners on the part of the Enterprise crew.
