The Imperial Anti-Terrorism Watchline, also referred to as the Imperial watch-line, functioned as a service provided by the Galactic Empire that focused on maintaining the security of the galaxy. Individuals could reach out to this service to report instances of terrorism. During the period spanning from 3 ABY to 4 ABY, Deathstick, a Crimson Dawn assassin, utilized the watchline to relay information regarding a rebel base located on Panisia. This base was the location of the Second Division belonging to the rebel fleet. Subsequently, the watchline communicated this report to the Imperial Security Bureau, who then notified Commander Ellian Zahra about the division's presence on Panisia. Consequently, Zahra dispatched her Star Destroyer, known as the Tarkin's Will, to Panisia with the objective to destroy the division.
