Ch'gran was a great Klingon warrior who lived approximately a thousand years ago. In the wake of the Hur'q invasion and looting of Qo'noS, Ch'gran rose to prominence by urging the Klingon people to take to the stars and conquer all threats before they suffered another invasion. Using captured Hur'q facilities and technology, Ch'gran oversaw the construction of a fleet of mighty warships, numbering seven in total, and on the anniversary of the Hur'q invasion, Ch'gran and the fleet ventured forth into space. The fleet later sent word that they had located a world on which to plant their flag, but were never heard from again.
