I agree with the flame war part.
Let me make it clear that we are discussing everything that occurs between a few years before The Reckoning, The Reckoning itself, and after (unless we wish to amend that as well).
So, as we all know, F-Klak (clone of the original Klak) eventually rises to power and forms his own empire. He is competing against F-Blackout for complete control of the universe, apparently because the Users gave him the right to do so. He has also begun time traveling to the past to ensure that the original Klak is of the proper mental state once he is cloned on the Cadmus facility on Korasa.
However, Ynot awakens from his slumber, and, on his way to kill the Users, takes down F-Klak's flagship, rendering him unconscious. When he awakens, He finds that F-Blackout has gained the upper hand, and that most of his empire was exiled to a region of space known as the Dark Area (forgot the name).
In order to retake his chunk of the multiverse, F-Klak creates a group known as the Dark Green Lanterns, along with taking over both the Sinestro Corps and the Red Lantern Corps. He also takes control of all his remaining forces, and begins his assault. The Reckoning begins.
Meanwhile, a Mysterious Masked Stranger, along with F-Zev and F-Kakamu, has formed a Resistance movement aimed at fighting both F-Klak and F-Blackout. The Resistance aims to restore peace to a multiverse shattered by war. However, their fight has not been going well. Both empires are strict, tyrannical, and powerful.
Eventually (after a few years of war and conquest), F-Klak leaves to the past, and does not come back. The empire gets worried, and eventually, fighting begins to break out amongst different factions. F-Klak's entire empire is in civil war. This leads to the Resistance wondering whether or not it should make a large scale strike (even though the empire is fragmented, it is still much more powerful than the resistance). The Mysterious Masked Stranger tells Wareshu XV, an elvin historian and archaeologist, to look for the tomb of a familiar hero. This hero will be awakened, and will eventually help the Resistance take down all of F-Klak's generals, and restore peace.
I also want to fit Raziel into all of this.
And that's as far as I am on my end.
