The whole innovation of the Silver Age reinvention of the Green Lantern was to model it after the E.E. Smith novel series "Lensman", about interstellar heroes who are granted a device by a group of benevolent aliens to police the galaxy. In the very early days of the Green Lantern comics, Hal actually never spoke in person with the Guardians. They would bring a projection of his unconscious mind before them, but he wouldn't actually remember the meeting, just their instructions. So it wasn't until Tomar Re, an alien lantern from a neighboring Sector, showed up that Hal started to get a concrete sense of the organization he was working for... and a few issues later, Hal started to meet the weird alien lanterns from all corners of the galaxy, and the Green Lantern Corps as we know them had arrived.

The Green Lantern Corps Comic History

For a long time the Green Lantern Corps would appear in the pages of the Green Lantern Comic, often as an authority for Hal Jordan to defy, although the members of the Corps all seemed to be roundly in support of him. In the broader sense, The Corps was just the framing device for the hero's origin, like Krypton exploding, in practice it actually proved to be fertile ground for new stories in it's own right. We would meet new Lanterns during the course of Hal's story, but just as often characters would be introduced in their own standalone short stories, showing just how prolific the concept of these space police was. The anthology books telling short stories about the Lanterns are some of my favorites.

It's noteworthy that while Green Lantern was a huge part of starting the Silver Age of comics, it's popularity wasn't always consistent through the years. Often the book would read as if it's trying to revitalize itself. Through it all, while the individual narratives at play were a bit hot or miss, the framing device of the Corps itself remained consistent.

The 80's began with a massive crossover book, Tales of the Green Lantern Corps. it effectively upped the ante in the story of the Lanterns, bringing thousands of characters together at once, introducing new ones. The Corps fought in huge crossover battles during the Crisis of Infinite Earths, but afterward, the organization was broken up. The individual Lanterns were free to choose where they made their home, and in a move that I never personally thought was adequately explained, a bunch of them chose to come and live on Earth.

It was pretty clearly a move to attempt to make the Green Lantern Corp more like the bestselling X-Men, but the characters were a little too same-y and the writing just not good enough to carry the book. This is an odd period for the Green Lantern Corps; unique in that it might be the only time when it's not meant to describe a galaxy-spanning police force with thousands of members, but rather a group of a half-dozen or so individuals all living under one roof and arguing over who needs to take out the trash. The book was cancelled in 1988.

In 1990, a new Green Lantern series began with Hal Jordan starting to recruit a new Corps, grabbing veterans from the original series and introducing new ones. This is the series that included the destruction of Coast City and Hal's insane attack on Oa and the destruction of the Corps... but it's noteworthy that the Corps he was destroying wasn't in fact the one that had been around for 30 years of comics, but one that had been rebuilt in the last three.

After a decade of Kyle Rayner being the sole Lantern in the Galaxy, Geoff Johns came onboard and restarted the Green Lantern Corps proper, making it even bigger as each sector now had TWO Lanterns (clearly to accommodate the fact that Earth has so many). Johns wrote a massive amount of content stretching over multiple series... It's a good read, but of course this is basically where we stop following along with the continuity of the comics because his ideas broke away from existing canon so severely.

Our Green Lantern Corp Story

To begin with, some of the best Green Lantern stories are the individual one-off short tales that have happened over the years, so a lot of our story is going to be built from all those little tales coming together. The overall timeline of the Corps is built from the major battles it's dealt with, which include the attack on Oa by Legion during Hal's first year as a Lantern, the various attacks by Sinestro, or the Manhunters, and most importantly, the fall of Oa and the Corps at the hands of Hal Jordan..

Kyle is going to serve for several years as the lone surviving Green Lantern, but we're manufacturing a story where he discovers that Sinestro is amassing forces, and travels across space finding certain former Lanterns, each with pieces of what he needs to relight the Oan Battery. In the end he's able to re-assemble the Corps as surviving lanterns from all across the Galaxy have their rings re-powered, and they are able to come to help him defeat Sinestro's forces, and begin the Corps again.

In our timeline, the distinction between the Corps before Hal's attack and after is more pronounced. In the comic, Geoff Johns brough almost everyone back from the dead, even ones Hal hadn't personally killed. In our timeline, the loss of life from each of the battles the Corps fights is tragic, and those Lanterns who fall... fall. Which means that we're constantly seeing the induction of new Green Lanterns. This isn't just one of a half dozen Lantern Corps scattered across a galaxy that doles out power rings like candy... this is a singular group of unique heroes serving as a beacon of righteousness for the whole Galaxy.
