X-Men: The Onslaught Revelation (2021) #1

YOU HAVE STRAYED FROM THE WAY OF X. THE ONSLAUGHT IS UPON YOU! The X-Men’s greatest foe, mutantkind’s primal evil, slithers in the minds of its most senior leaders... The kids whisper of the CRUCI-BALL: a party to end all parties. A party to end everything. The seals are broken, the trumpets have sounded; only a small band of eccentric mutants can hope to break the fall... Can Nightcrawler light the spark that will drive out the shadows... or will Krakoa slip into the abyss...?
