Mr. Sinister has managed to drag the Hellions into his mess after a back-alley deal with Mastermind ended with him being double-crossed and kidnapped by Arcade. Using Sinister as bait, Mastermind falsified a mission from the Quiet Council that led the Hellions into an ambush and trapped them in their own individual fantasies. Separated from their teammates and cut off from Krakoa...it can't get any worse, right?
