[Source] Null Cannons were a type of superweapon developed by the Galactic Republic by the time of the Cold War. It functioned by firing energy blasts that completely disabled enemy technology such as starships. A prototype was present amongst the Republic Navy fleet at Hoth before they crashed on the planet during the battle against the Sith Empire. There they remained until a Republic Military initiative on the planet led by Admiral Revald sought to reclaim the weapon for use against the Sith. This operation was aided by a notable Republic citizen but faced opposition from the local White Maw pirates that intended to claim the weapon for themselves. Pirate Captain Sero was involved with making numerous replicas of the Null Cannon during this time with the intention of distributing them amongst his forces. Sero attempted to negotiate trading the cannons to the Republic, but a surprise back up strike team made him believe the negotiators had betrayed him and attacked but was defeated.
