“There's Something Awful on Muir Island!”

In "There's Something Awful on Muir Island!", the X-Men are pulled back to the site of their past battles when Moira uncovers a terrifying truth: Proteus has escaped. As Jean grapples with unsettling visions tied to her Phoenix powers, and Mastermind’s illusions begin to blur reality, Beast tracks down the team with urgent news—Moira needs them, and Muir Island is no longer safe. Written by Chris Claremont and brought to life by John Byrne’s dynamic art, with Terry Austin’s inks and Glynis Wein’s colors, this 1979 issue delivers a tense, character-driven mystery. The cover by Dave Cockrum and Terry Austin captures the eerie tension of the island’s secrets.
