Besides resurrecting the X-Men, Roma gave them a mysterious jewel called the Siege Perilous. The magical gem could enlarge to a giant portal. All who entered would be judged by higher powers, their good acts and ill deeds weighed, and be reborn in a new life without remembering their past lives. The X-Men found no use for the jewel during the Inferno, against the alien Brood, or when returning to the Savage Land. Curious, Dazzler used her powers to take a look inside the illuminated gem. She saw various alternate versions of herself before they were all murdered and merged into a single being that warned Dazzler everyone dies sometime.
Later the same day, a merged Nimrod/Mastermold attacked the X-Men. With only herself and Rogue left standing, Dazzler threw the Siege Perilous behind the Sentinel hoping her enemy would be sucked into the portal. While the portal appeared, the Nimrod/Mastermold anchored itself to the ground and grabbed Rogue as she tried to push it through. With no other choice, Dazzler blasted both of them into the gateway.
With Rogue presumed dead, and other members leaving the team, the X-Men were down to only Havok, Dazzler, Colossus and Psylocke. Back in the Savage Land to rescue Polaris, Psylocke had a precognitive vision of the X-Men dying back in the Australian Outback and a bound Gateway pointing to the Siege Perilous. Worried about her vision, Betsy wasn't able to warn the others before Gateway teleported them back to the Outback.
Immediately sensing the Reavers approaching when they returned to Australia, Psylocke suggested using the Siege Perilous to escape as the X-Men were in no condition to face the deadly cyborgs. After a brief discussion, and telepathic convincing of Havok, all four mutants entered the gateway. As the portal collapsed back into a gem, Donald Pierce arrived and smashed the jewel to pieces.
Weeks after entering the gateway, Rogue returned to the empty Australian base with her memory intact. At first believing the cosmic judging was a joke, she realized the memories she contained belonging to Carol Danvers were gone. She was then attacked by Ms. Marvel, and discovered the Siege Perilous had given both personalities within Rogue a body connected to a single life force. Rogue was prepared to die, but Magneto intervened and killed Danvers. The two spent time in the Savage Land, allying themselves with Ka-Zar against Zaladane, and began to become attracted to one another. Their relationship ended before it had a chance to blossom once Magneto killed Zaladane, which Rogue opposed.
