Sector 0

Sector 0 is a location in Midgar in Final Fantasy VII. Aboveground, it is the space on which Shinra Headquarters stands. Below, it is the main base for Deepground in Dirge of Cerberus -Final Fantasy VII-. The area seems to be a war-torn city with burned ruins of buildings. Though it is entirely underground, there is enough space above for helicopters to fly. Above, there is no sky, only an empty blackness that looks similar to night. The Sector 0 Reactor is located here.

Storyline
Vincent Valentine enters Sector 0 to defeat the Tsviets and stop the coming of the Omega Weapon during the Battle of Midgar.
