DEMONS, BEWARE… …the X-ORCISTS are here! When a demon escapes Limbo and begins terrorizing humans and mutants alike, MAGIK and JUGGERNAUT of the X-Men team up with MADELYNE PRYOR, the Queen of Limbo herself, to take it down. But this demon is unlike anything they've ever seen before, and they're going to need help to stop its ruinous rampage. ASHLEY ALLEN and GERMÁN PERALTA, the all-star writer-artist duo who brought you MAGIK, join forces again to spin a spine-tingling tale!
