The demon lord Belasco has pulled the Xavier Institute into Limbo, but he's not after the X-Men... he's come for the New X-Men. With their leaders cut off, most of the team captured, and a group of students thrown into the demon infested wastelands, all hope seems lost. But the kids aren't alone in Limbo... and things are about to get much, much worse. Collects New X-Men #37-43.
