For the regular universe counterpart, see Husnock (planet).

In the mirror universe, Husnock was a planet which came under the control of the Terran Empire some time during the mid to late 23rd century.

Under imperial control, the entire planet served as a containment camp for the native and psychotically violent species of the planet who were also known as the Husnock. The empire maintained several bases on the planet where scientists used behavior-modification techniques with the intention of disciplining the Husnock and subsequently forcing them to serve the empire's needs as ground troops.
