Well, it's been like 8 hours since I posted the last the page and the Imperial War one-shot still hasn't been ripped yet. So we'll just continue with the Avengers issue.
But yes, the Avengers title is also joining us again in this thread. Cyclops' X-Men are making in guest appearances this arc following up on the promise back in Issue #21, so I'll just cover it here just to be sure.
Last issue was mostly a recap of the main plot of the series and shuffled some stuff in order to accelerate the story. Basically (from what I understand since I haven't kept up with the series to be honest), there exists a moment in time where no time traveler is able to access known as the "Missing Moment". Inside it is "the Grail", which allows its wielder to create a new iteration of the multiverse at the cost of destroying the current one. The only way to enter the Missing Moment is for a group of heroes (ie. the Avengers) to go through a series of apocalyptic threats known as the "Tribulation Events". But another pursuer of the Grail known as Myrddin has instead cheated the system by tearing open a giant worm hole that is supposedly going to lead straight to it. Not only that, the Missing Moment happens to just be the creation of the Eighth Cosmos in Secret Wars!
