Sector Four is shown under siege by the Confederacy.
Sector Four was one of the districts located on the planet of Coruscant. During the Clone Wars, specifically during the Battle of Coruscant, Captain Fordo and his squad were tasked with defending the plaza from incoming droid fire. However, they were eventually overwhelmed by the enemy forces. Fordo then gave the order for his troopers to retreat, but Master Yoda intervened shortly after, rescinding the prior order. Additionally, Mace Windu was able to pilot a captured droid starfighter to provide aerial assistance to the rapidly diminishing forces.
