Following the foundation of the mutant state of Krakoa, Charles Xavier established a group of mutants known as “the Five” (Tempus, Proteus, Hope Summers, Elixir, and Egg) with the goal of resurrecting all the fallen mutants.
The five combine their mutants powers in order to resurrect deceased mutants. During this process of mutant resurrection, Egg produces a number of nonviable biological "eggs," equal to the number of mutants the Five have to resurrect. The eggs are then injected with mutant DNA from Mister Sinister’s genetic catalogue, and then made viable thanks to Proteus’ reality-altering powers. Elixir biologically gives the eggs life starting a new cellular replication process and husk growth, and then Eva Bell uses her time manipulation powers to maturate the husks to the age the mutants were when they died. Hope Summers uses her powers to empower everyone else’s abilities in the process. Hope's powers allow the Five to operate at both their peak and in unison. A telepath the copies over the mutant's conciousness, recorded by Cerebro, from a copy made at the time of their deaths, onto the husk. Through this process, the Five are effectively able to make new clones of deceased mutants, restoring their bodies, their powers, and their minds as they were at the time of their deaths.
The more the Five practiced their resurrections, the easier the process became. Also, these five mutants appeared to become an inseparable family unit and were almost never seen apart from one another. Their connection appeared to have extended beyond the union of their powers, reaching the mutants themselves. On Krakoa, the Five were considered sacred and were to be proteced at all costs.
Because the powers of Proteus were directly associated with the destruction of his own body, The Five had a backup mutant husk prepared for Proteus to inhabit when he burned out his old one. Depending on the frequency with which he used his powers, a Proteus body normally lasted one week, or even a single day during periods of excessive power use.
Due to the complexities of making sure who is dead, missing, or simply displaced, so there won't be multiple versions of the same mutant alive at once, the formation of X-Factor was approved. X-Factor Investigations would confirm the whereabouts and status of missing and potentially deceased mutants, and inform the Five on their findings so they could start the resurrection process.
The resurrection protocols were briefly shut down when Rockslide was brought back from his death on Otherworld with his mind scrambled. It was concluded by The Quiet Council and X-Factor Investigations that mutants who die on Otherworld can't be brought back. After Saturnyne's Ten of Swords tournament ended resurrections where resumed.
- The Quiet Council and the Five agreed that clones such as Madelyne Pryor can't be resurrected due to the similarities to their progenitor. The Five broke this rule by resurrecting Gabby Kinney and afterwards filed a formal request to the Council to change this ruling, arguing that Cerebro registered these "clones" as individuals separate from their genetic originals, and that they therefore deserved resurrection. 
- Due to Otherworld's connection to the entirety of the Multiverse, mutants that die there cannot be restored to their original selves. The first attempt to do so resulted in the resurrected mutant being transformed into an amalgamation of their multiversal counterparts, drawing on enough energy to temporarily shut down all five Cerebros and the Five's connection, and corrupting the copy/essence of the mutant's mind in Cerebro.
- The Five need a telepath and Cerebro in conjunction with the resurrection process to implant the essence of the newly created husk to complete the process.
- If a member of the five dies themselves, Sync and Mimic are on reserve to fill their role during their resurrection.
- If a mutant dies on Amenth they will be brough back in an evolved form, with their powers and skills improved and their personality slightly altered.
