On September 5, 2019, the unthinkable happened in the lives of the X-Men: their leader and mentor, Professor Charles Xavier, disappeared. Not only that, his former friend and colleague-turned-super villain, Erik Lehnsherr, disappeared as well. Where either of these men went is anyone's guess. No trace of either has been found.
Scott Summers has taken over as interim headmaster of the Xavier Institute for Higher Learning, a position he is not comfortable in.
The Brotherhood have disbanded without their leader and Mystique refuses to step in but that usually means she has another plan, one called Freedom Force.
Sebastian Shaw and the Hellfire Club appear completely unperturbed by any of this. Do they know something about the disappearances?
Where they go from here is YOUR story. Do you want to join the X-Men in searching for their beloved mentor? Do you believe that Mystique and Freedom Force has a better option? Or perhaps you would like to play in the big leagues and the Hellfire Club is more suited for your tastes.
Wherever you end up, play your part well. You might not survive the consequences otherwise.
