Margh was a male Klingon and member of the Klingon Defense Forces. In 2373, Margh was selected to join the Order of the Bat'leth and attended the initiation ceremony in the Hall of Warriors on Ty'Gokor. When Odo attempted to place a polaron emitter only to have it knocked out of his hand, Margh picked up the emitter. Worf approached Odo and Margh and claimed that the device was a Vulcan toy called a tinghamut that had been taken from Archanis for "Kodrak's" son. (DS9 episode: "Apocalypse Rising")
