Between 3 ABY and 4 ABY, the Crimson Dawn assassin Deathstick contacted the watchline to inform them of a rebel base on Panisia, which housed the Second Division of the rebel fleet, The watchline informed the Imperial Security Bureau of the report, who then alerted Commander Ellian Zahra of the presence of the division on Panisia. In response, Zahra had her Star Destroyer, the Tarkin's Will, travel to Panisia to destroy the division.
