Space sector

A space sector is a region of charted outer space. In DC Comics continuity, the Guardians of the Universe mapped out the entire occupied universe and assigned a member of the Green Lantern Corps as the protector of each space sector. Traditionally, there are 2,300 known space sectors.

Sector 0
Sector 0 exists at the very center of the universe. It includes the So-Oa stellar system, which contains the planet Oa. This is the headquarters of the Guardians of the Universe, as well as the Green Lantern Corps. Sector 0 has routinely been invaded by conquering races and armies including the Sinestro Corps.

Sector 674
Sector 674 contained the planet Bolovax Vik. It's Green Lantern protector was Kilowog. Bolovax Vik was ultimately destroyed, but Kilowog managed to save the souls of six million Bolovaxians by housing their essence inside of his ring.
