Mutantkind has never had a greater fall. From the highs of Krakoa-their own glorious nation, a place where they were safe and happy-to the lowest of lows. Outlawed, hunted, killed, most of their kind missing or dead, and now, one their greatest leaders, Cyclops, is on trial facing a death penalty. Ready or not, the time has come for the X-Men to make their final stand against the forces that have struck them low. The day is now. The place is here. The tale of the house Xavier built will long be told...and few will forget this darkest chapter.
