Pao'la was a planet in the Klingon Empire, largely covered in dense jungles, and a rich source of dilithium. In addition to a commercial spaceport, Pao'la was the site of a secret prison, populated primarily by beings from outside the Empire. It was administrated by Commander K'zeq from at least 2279 to circa 2281. Following K'zeq's retirement, Commander Korax was made commander. The prison housed approximately a thousand prisoners, and employed over a hundred guards, including Khulr and Moqlah.
