The Planetary Superweapon Non-Proliferation Treaty or PSNT, was a treaty signed by several galactic powers following the Galactic Civil War, in 21 ABY. It's objective was to prevent the spread of superweapons with the ability to destroy or devastate a planet or planetary body, mainly after the Galactic Empire and its successor states developed the Death Star's, the Galaxy Gun, the Sun Crusher, and the World Devastator, and the Besadii Hutt clan developed the Darksaber.
