John Stewart: The Emerald Knight #1 bridges the end of Green Lantern and the start of Dark Crisis

gamesradar.com:

The last volume of the Green Lantern ongoing series ended with something of a cliffhanger and the promise of the return of not only the new Godstorm-powered, sword-wielding 'Emerald Knight' version of John Stewart but the return of the Emerald Knights (plural) as well.

Is that the Green Lantern Corps rebranded?

DC doesn't say it outright, but their promised return will happen in November in John Stewart: The Emerald Knight #1, a 48-page one-shot by the last Green Lantern series' creative team of writer Geoffrey Thorne and Marco Santucci.

According to the publisher, John will have to "become something greater" to save his fellow Green Lanterns and escape the Dark Sector where the Green Lanterns have been trapped for "months" as he faces Esak, the mad New God, in the special.

Although DC also doesn't come outright and say it specifically, the special seems to take place after the events of April 12's Green Lantern #12 (opens in new tab) but before the events of April 26's Justice League #75 (opens in new tab) and subsequent Dark Crisis on Infinite Earths event where John participated in the battle against Pariah and the Dark Army and appeared to be killed (but was instead whisked off to a happiness prison) along with his Justice League teammates.

Hal Jordan has also been a major presence in Dark Crisis so the Emerald Knight special seems designed to wrap up the Dark Sector Green Lantern storyline and catch things up to the beginning of Dark Crisis continuity.

For those of you late to the ballgame, here's an explanation of what Stewart's Godstorm powers are, and what happened in the final issue of Green Lantern as well as Justice League #75.
