The Battle of Grimdock, additionally referred to as the blockade of Substation Grimdock, transpired in orbit above the prison moon known as Substation Grimdock. This event was triggered after Sergeant Magernon extended amnesty to a significant number of prisoners. Subsequently, starships from various pirate groups converged on the moon to retrieve the released convicts, prompting the New Republic Defense Fleet to enact a blockade, effectively trapping the pirates and thwarting their attempts to flee. Ultimately, Fyzen Gor, a Pau'an gangster aboard the pirate frigate Radium Destrobar, executed a maneuver where his ship collided with another pirate flagship, facilitating his escape amidst the ensuing chaos. With the loss of their two primary warships, the remaining pirates conceded defeat and surrendered.
