Formally known as the Justicars' Brigade, this militia was formed in the years after the Sacking of Coruscant, when a crime syndicate began seizing control of Coruscant's lower regions. The Republic Senate lacked the resources to challenge the syndicate‒later called Black Sun‒and withdrew its security forces.
Outraged at Black Sun's treatment of the local citizens, a group of ex-military individuals formed the Justicars, intending to retake their neighborhoods. However, eliminating Black Sun and regaining control proved more difficult than the Justicars had expected. They took extreme measures to restore order, beginning with a simple curfew and culminating in the imposition of martial law.
The Justicars have now instituted checkpoints and armed guards throughout their territory, acting with lethal force against anyone lacking “proper clearance.” Their unshakeable belief that this is necessary to keep people safe only makes the Justicars more dangerous. Coruscant's government has declared the Justicars a threat to be dismantled, and the Justicars have cut off all communication with outsiders.
