The Planet Prison was a superweapon developed by the Galactic Republic during the Cold War with the Sith Empire. Created by Doctor Nasan Godera and weaponized by a team of scientists under the leadership of Doctor Tarnis&mdash;in actuality a Sith Lord and the son of the notorious Darth Angral&mdash;the weapon was intended as a way to peacefully blockade a planet. When the project's prototype neared completion, Tarnis attempted to steal the device and use it on the Republic capital world of Coruscant through an elaborate ruse with the help of the Migrant Merchants' Guild and Black Sun criminal organizations. However, Tarnis was killed in the ruins of the Jedi Temple by a young Jedi Knight, and the device was destroyed before it could be fired. The technology would be later combined with several other weapons by Darth Angral into the ship-mounted Desolator superweapon, which the Sith Lord used to devastate the planet Uphrades, although the Jedi Knight defeated Angral aboard his warship above Tython just before the ship was destroyed by Republic fighters.
