POWERS OF ESSEX! It's the end of the world as we know it, and at least Sinister feels fine. For now. Can that last? Especially when we discover that he really is his own worst enemy... The universe-melting X-event begins here, in a horror timeline that makes Age of Apocalypse look like the X-Men Swimsuit Special. Join Kieron Gillen (IMMORTAL X-MEN, AXE: JUDGMENT DAY) as he kicks off the X-Men crossover Sinister has been planning since the beginning and is going to have to see through to the bitter end.
