Warning: The following contains SPOILERS for Crisis on Infinite Earths Giant #2

A comic book tie-in to the Arrowverse Crisis on Infinite Earths crossover has offered up the first in-depth look at the world of the HBO Max Green Lantern show. The short story also confirmed the existence of several popular Green Lantern Corps members in the reality of the upcoming HBO series, while detailing an untold tale from the event.

One character who was notably absent from the Crisis on Infinite Earths crossover was Felicity Smoak; Team Arrow’s resident hacker and Oliver Queen’s widow. Despite this, Felicity was said to have played a major role in the crossover, having located an artifact called the Book of Oa. It was through this book that Felicity found the first clues needed to start tracking down the Paragons; seven beings who were destined to rebuild the multiverse in the wake of the Crisis.

The details of how Felicity came to read the Book of Oa were revealed in Crisis on Infinite Earths Giant #2; the second of two comic book specials based on the television event. The comic revealed that Felicity (along with The Ray and Nyssa Al Ghul) traveled to Earth-12; the world later designated as the setting of the upcoming HBO Max Green Lantern show. From there they went to the planet Oa; home of the Guardians of the Universe and keepers of the Book of Oa. Unfortunately, the Guardians refused to allow Felicity to have access to Book of Oa, claiming that for a mortal to even gaze upon a single page of the Book of Oa would liquefy their brain and leave them begging for the release of death.

Thankfully, it was at that moment that the Anti-Monitor and an army of shadow demons attacked Oa, having followed Felicity while seeking to stop her from learning more about the Paragons. Soon every Green Lantern on Oa was moving to defend the Guardians from the shadowy invaders. During the confusion, the Guardian Ganthet (who had been the only Guardian to show any sympathy to Felicity) transported Felicity to the archive where the Book of Oa was kept and safe-guarded her as she attempted to utilize the cosmic artifact.

As the battle with the Shadow Demons raged on, several faces familiar to fans of the Green Lantern Corps comics beside Ganthet made an appearance. Chief among these was Thal Sinestro, once known as the greatest of Green Lanterns. Sinestro was seen fighting alongside the Green Lanterns Kilowog and Tomar-Re, with the three allies agreeing to a wager as to who could slay the most Shadow Demons. The battle scene which followed was reminiscent of the Battle of Helm’s Deep from The Lord of The Rings: The Two Towers, with the Green Lanterns calling out the count of how many Shadow Demons they had vaporized as the fighting continued.

While it’s not much of a shock that the upcoming Green Lantern show should include such popular Corps members as Tomar-Re and Kilowog (who both also appeared in the 2012 Green Lantern movie), it is a bit of a surprise that Sinestro, the most famous of Green Lantern villains, is still numbered among the Green Lanterns. Presumably the upcoming show will tackle Sinestro’s fall from grace as an on-going subplot, showing how paranoia about his homeworld falling into chaos inspired him to become a tyrant, ruling his planet with an iron fist until his crimes were revealed to the Guardians by an idealistic newbie Green Lantern. Perhaps John Diggle will be the Lantern to do this in the newly reborn Arrowverse.
