KRAKOA HAS JUST BEGUN TO FIGHT! 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. From writer Gerry Duggan (X-MEN, MARAUDERS, UNCANNY AVENGERS) and artist Lucas Werneck (IMMORTAL X-MEN, TRIAL OF MAGNETO) comes half of the story that will bring the Krakoa Age to its conclusion!

WHO IS TRAITOR X? In the aftermath of the greatest betrayal in X-Men history, the Quiet Council in exile must act. They have a plan. Can anyone, or anything, survive the experience? As the Krakoan Age barrels toward its conclusion, the two series that are one converge on an act that will live in infamy!
