See its issues like this why I like Taylor's writing, because he remembers that he's writing in an entire interconnected universe. Because Taylor utilizes specific aspects of the marvel universe to not only enhance this story but subvert apocalyptic expectations and tell a good story.
So the issue starts off with the power being gone and the world goes mad...but its our heroes that we all know and love who get the world to chill out, especially the X-men. That our heroes showed them the way that it doesn't have to be bands of raiders in leather or scattered gear and create a world that is nothing like say Old Man Logan, because with the help of telepaths like Jean Grey and Professor X even without Power there can still be a way to connect the world. And with the world connected the hidden innovative nation of Wakanda steps up to the plate and with some of the smartest minds of the marvel universe create new ways to expand human kind and help meet everyday needs in a five year time jump. While the geniuses innovate others protect, with heroes establishing systems to detect vampires and werewolves who have only risen in these dark times. It's a true utopia they managed to build for themselves showing only the best of our heroes.
Unfortunately there is always someone trying to destroy the world, and that someone is Apocalypse. In the end times he's managed to take Europe as his own, and only done so much worse. He's aligned with Dracula and his vampiric army and he's used Killgrave to enslave people to his will people such as Magneto, Riri Williams, Reed Richards, and now Tony Stark. And his goal you ask? To gain the power of the unmaker, the very thing that caused the end of the world.
I honestly really like this issue, because Taylor just uses ideas that are just so inherently marvel to tell a story that could have been generic wasteland of the apocalypse and instead showed that a world filled with good heroes can save it even when the world is falling around them. I don't even recommend it if you are a Tom Taylor fan, if you simply like Marvel comics you should read this.
