How are the Green Lantern Corps Sectors arranged? I know 0001 is Oa, but how are they arrayed through the universe? Are they amorphous shapes like terrestrial geography or is there some uniformity in spatial size?

Despite the name of the Guardians (who call themselves the Guardians of the Universe) the correct name for the regions of our galaxy which their Green Lantern Corp have jurisdiction seems limited to our galaxy proper and has been called 'The Oan Protectorate'.

  • The 3600 sectors they protect are centered on Oa (the center of the Universe, or so the Oans tell us) and are triangular wedges which originate from this location. Sector 0000 is Oa and at the center of the protected regions. This makes Oa the most well-defended region in the protectorate since every sector corresponds with Oa. A Green Lantern is still within his sector even if he is standing on Oa.

  • The sector 0001 is the antimatter universe. (This was likely due to the transdimensional storage of Parallax as a yellow impurity within the Green Lantern battery. Since Parallax has been released, that sector may have been reassigned.)

  • Some regions are teeming with life, others have barely any at all. How they are assigned is undetermined. There are sectors outside of their sector designations which are not protected, nor visited regularly by the Green Lantern Corps. Sector 3601 was the region where their previous vassels, the Manhunters retreated after they were replaced.

To be perfectly honest, DC has never clearly defined the regions effectively even though they have happily assigned sector after sector in different stories eventually having to compile a list of sectors used. See: Sector Guide > Book of Oa.

For the record, I have problems with the Green Lantern Corp only needing 3600 members to patrol the entire Universe (hence my assertion they only patrol our galaxy or local group of galaxies) given that our galaxy alone has 200+ billion stars, it means that each member of the Corp in our Galaxy alone had 5,555,558 stars to patrol!

A correction that I was recently reminded of. In the GLC of the DCnU, there are 2 Green Lanterns per sector making a total of 7200 (give or take, Green Lanterns working for the Guardians) at any given time.

The Oan Protectorate

For a listing to the sectors and the Green Lanterns who patrolled them in the Post-Crisis but not necessarily DCnU universe, you can read the listings at the Book of Oa. They do their best to keep up with the changes in the DCU but it is a never ending task.

  • SO, in short is a largely arbitrary designation based on the whim of the writer? Wonderful.... And aren't two Lanterns assigned to each sector? – Jared Tritsch Nov 25 '12 at 0:59
  • That's right. I remember a recent adjustment to the GLC indicating there are now 7200 Green Lanterns! Now they can split the load! – Thaddeus Howze Nov 25 '12 at 1:03

Imagine a pie that's been cut into 3,600 'slices', and the very center of the pie is Oa.

The back part of each slice may not have a 'crust', meaning that each sector goes on to infinity...or at least the known universe according to the Guardians.

  • Ha! An evocative, and a surprisingly helpful, illustration. Although I'd add that it's three-dimensional, sliced both horizontally and vertically. – Nerrolken Sep 4 '15 at 16:19

In the mini-series Tales of the Green Lantern Corps, writer Mike Barr said the 3600 sectors were arranged "like the spokes of a wagon wheel" each one tenth of a degree of the circle. The problem with that layout, as with the layout depicted above, is that each sector is an ever-widening arc or conic section, extending to the end of the universe, meaning effectively that each sector is infinitely large.

The main conceit of the sectors starting at Oa was that it meant that technically, Oa was in every Corpsman's sector, and as such could be called to report there while still maintaining patrol in their sector.

There was also an assertion for some time that the sectors were of irregular size - some sectors had many planets but were smaller, and vice versa. IIRC, G'nort Esplanade Gneesmacher, when he became an official GL, was given one of the few sectors that was almost entirely empty.

It's fair to assume that the appellation saying they guarded the entire universe is indeed a combination of ego and marketing. "Guardians of the Virgo Supercluster" seems a bit off.

  • While wedge-shaped sectors strikes me as being... stupid, I believe that your assertion (that each sector is infinitely large) is incorrect. The universe that Green Lantern Corps exists in is bounded by the "Source Wall". – This isn't my real name Aug 18 '16 at 19:39
  • A good point, but The Wall's location is never specified, save for it's at the edge of the universe. Considering Apokalips and New Genesis live outside of normal space and time, it could also be someplace outside of "our" universe", depicting only a place past which we may not go. – VBartilucci Aug 18 '16 at 19:42
