Using skin grafts from Domino, XENO mercenaries were able to infiltrate Krakoa's defenses and successfully assassinate Professor X, destroying Cerebro in the process. Before Professor X was resurrected, Magneto reshaped the broken shards of Cerebro into the Cerebro Sword.
While examining the corpses of XENO's enhanced soldiers in the Healing Gardens, Beast, Sage, and Cecilia Reyes were all shocked to discover that the soldiers were biologically engineered to have smaller agents nested inside them. One of these small soldiers was able to steal the Cerebro Sword, murder Kid Omega with it, and use his dying body to access a Krakoa Gateway to Russia to deliver the sword to Mikhail Rasputin. Mikhail then presented the sword to The Man with the Peacock Tattoo and XENO. In an effort to decrypt the information held within the Cerebro Sword, Mikhail attempted to procure a load of Shi'ar logic diamonds. This plan was inadvertently thwarted by Solem, who stole the logic diamonds for his own use.
X Lives and X Deaths of Wolverine
Using a combination of his own reality warping powers and the Cerebro Sword, Mikhail sent Omega Red's consciousness into the past to kill Professor X and/or his ancestors. To counter this attack, Professor X and Jean Grey used another Cerebro to send Wolverine's consciousness into his past bodies to stop Omega Red from murdering anyone in the Xavier line and changing the timeline. After finally defeating Omega Red in the present, Wolverine brought the Cerebro Sword back to The Pointe. However, as soon as Wolverine arrived back on Krakoa, he was dispatched to stop the Phalanx-possessed Omega Wolverine from infecting the Cerebro Cradles. While Wolverine, Laura, Daken, and Scout tried to stop Omega Wolverine, Sage programmed the Cerebro Sword with nanites meant to counterprogram the Phalanx virus. Sage was able to rush the sword to Wolverine who stabbed Omega Wolverine's skeleton with it, purging the Phalanx virus and ending the threat. During the encounter, the Cerebro Sword was completely broken in half (seemingly destroyed).
- The sword is meant to represent Xavier's dream, once broken, but now forged anew and refined.
