​In this, the penultimate chapter of the critically-acclaimed epic "Darkseid War," the fate of the Justice League and the entire universe is on the line! But can even the combined might of the Justice Gods contend with the secret machinations of Grail, the deadly daughter of Darkseid? Death, rebirth and the life of one of the members of the League changed forever!

DC Comics Rebirth catalog hits comic shops tomorrow and few Green Lantern tidbits have hit a day early namely hints at the direction of the story line. Check them out below via Newsarama.

​Batman, Superman, and Wonder Woman comprise the big guns of the Justice League, but some of the other members have some major changes coming their way in Rebirth as well. For example, rookie Green Lanterns Jessica Cruz and Simon Baz will have to deal with a "rogue Guardian" in their new series.

"The Guardians created the most powerful weapon in the DC Universe-the Green Lantern ring," said Green Lanterns writer Sam Humphries. "But a rogue Guardian also created something more powerful and more unpredictable."

The massive “Darkseid War” epic continues to set the stages for the future of the DC Universe as we reveal the secrets behind its newest major player: Darkseid’s daughter, Grail! And if the Justice League is not careful, the spoils of war will all end up with her! See the truth behind Grail's role in this war and the future of the DC Universe as she tears her way across it.
