Extraordinary X-Men #16

"The epic conclusion of 'KINGDOMS FALL'! • Magik's protégé, Sapna, has become possessed by THE WORLD-EATER, an extradimensional entity whose sole purpose is to live up to its name. • And Magik's brother, Colossus, is under the thrall of one of the X-Men's greatest adversaries, APOCALYPSE. • As the World-Eater bears down on Limbo, everything Magik cares about is on the line - her ward, her brother and the world's surviving mutants. • What will it cost to save them all?
