During The Fall of X, the X-Men have seen their whole existence turned upside down, with the anti-mutant organization, Orchis, practically eliminating mutants from the entire planet, with over a hundred thousand mutants currently lost within the White Hot Room, other mutants sent to different parts of the Marvel Universe, and the remaining mutants on Earth forced underground by Stark Sentinels that can detect mutant powers from a distance. One of the mutants who has taken these developments the hardest has been Kate Pryde, who has adopted the codename Shadowkat, and essentially gone on a murderous rampage against Orchis.
