The planet Dathomir has a long history of use as a penal colony. The Galactic Republic had used the planet as a place to send various criminals and outcasts of society. These people were left on the planet with no possible means of escape to live out the rest of their lives in solitude.

The Imperial prison is overseen by the Imperial Inquisitor Olof. Prisoners kept here are some of the most dangerous to the Empire, and as such were left in this remote facility to be forgotten about. The prison is guarded by a regiment of stormtroopers.
