The M'rok were a species from the planet M'rokta'ra. They were descended from an arachnid-like creature and were tall and spindly looking. They had two pairs of black eyes and short purplish fur-like hair that covered their entire body. They had three fingers on each hand and long arms that made them excellent climbers. In 2366, the M'rok entered into an alliance with the Romulan Star Empire. They have since adopted many items of Romulan culture with Romulan aesthetics becoming a fad during the late 2360s and 2370s.
