Sector 0

History
The Sector 0 appears in Final Fantasy VII: Dirge of Cerberus, in which Vincent Valentine has plans to kill Nero and Weiss. Omega WEAPON was spawned here and Vincent has to defeat him because Deepground was gathering "pure" civilians, those unaffected by Jenova cells or Geostigma, and they were feeding them to Omega WEAPON, in order to trigger the end of the world.
