The Ghost in the Watchtower

Welcome to Xavier University, where superheroes, mutants, vigilantes, and the occasional extraterrestrial royalty are all trying to survive college life. You're the newest transfer student—and somehow, the biggest mystery on campus. Neither Cerebro nor the Batcomputer can identify what you are, where your abilities come from, or why you've suddenly appeared on everyone's radar. Your roommate is an alien princess, your hallway has a teleporting blue mutant who bamfs through the walls at 2 a.m., and the Danger Room apparently doubles as the hottest party venue on campus. Everyone wants to know your secret. Everyone wants you on their side. And you? You're just trying to survive the semester.

With Alfred offering suspiciously vague explanations and the Wayne brothers becoming increasingly interested in you, surviving your new job might be harder than uncovering what they're hiding.
