|K'Par Rinn, an Argrathi female (2372)|
The Argrathi were a humanoid species native to the planet Argratha in the Gamma Quadrant. Their government was known as the Argrathi Authority. As a form of punishment, the Argrathi implanted false memories of incarceration into convicted criminals. As the process was irreversible and tailored to each individual prisoner, the Argrathi claimed it to be more efficient and effective than maintaining a real prison system.
