Crystal teleports him to the Inhumans' home for medical attention, believing he had become suicidal upon the loss of his powers and unaware of his true connection to the events.
Deciding that he can not stand life as a human, Pietro asks Black Bolt for permission to undergo Terrigenesis, exposure to the Inhumans' power-granting Terrigen Mist.
Pietro's request is denied since he is of human blood, and Terrigenesis is reserved only for those of pure Inhuman stock to decrease the chance of a detrimental mutation.
The older Pietro explains that the Mists did give him powers — he has time-jumped fourteen days into the future, but the time-travel has a degenerative effect on him, hence his haggard state, and he can only move forward in time and only remain there for short periods before he is pulled back.
Manipulated by his older self, Pietro begins working to take the Terrigen Crystals back to Earth and restore the mutant population.
Pietro manages to get a container full of Terrigen Crystals to the past, and uses Lockjaw to take him and Luna back to his apartment in New York.
Pietro explains the basis of his plan concerning the Terrigen Crystals, and tells Luna he is going to give back her birthright, exposing her to the Mists.
Shortly after, it begins to rain, and each drop feels like a needle piercing Callisto, as her powers have been augmented to a much higher level than before.
He believes that the Inhumans have grown weak and dull with their luxurious, unchallenging lifestyle, and that by losing the Terrigen Mists they will grow strong again through adversity.
During the fight with the Inhumans, Unus the Untouchable loses control of his forcefield and suffocates himself to death, proving that the Terrigen Mists are unhealthy for non-Inhumans.
The fallout of Quicksilver's theft of the Terrigen Mists is examined directly in the six-issue follow up mini-series Silent War, in addition to being touched upon throughout X-Factor vol.
