Scarlet Witch as Carrie
Scarlet Witch as Firestarter
America Chavez and an alternate version of Dr. Stephen Strange are chased by a demon in space between universes while looking for the Book of Vishanti. This Strange is killed and Chavez accidentally creates a portal that transports them to Earth-616,[N 1] where this universe’s Strange rescues Chavez from an octopus demon chasing her by killing it with help from Sorcerer Supreme Wong.[N 2] Chavez explains that the demons are hunting her because she has the power to travel through the multiverse.
Recognizing runes of witchcraft on the demon and the alternate Strange’s corpse, Strange consults Wanda Maximoff, only to realize that she is responsible for the demons hunting Chavez. Since acquiring the Darkhold and becoming the Scarlet Witch, Maximoff believes that controlling the multiverse with Chavez’s power will allow her to reunite with Billy and Tommy, the children she created during her time in Westview.[N 3] When Strange refuses to surrender Chavez, Wanda attacks Kamar-Taj, killing many sorcerers. Chavez accidentally transports herself and Strange across the multiverse to Earth-838. Maximoff uses the Darkhold to “dream-walk” into the body of her Earth-838 counterpart, who lives a suburban life with her own Billy and Tommy.
While searching for help, Strange and Chavez are arrested by Earth-838’s Karl Mordo and brought before the Illuminati, which consists of Mordo himself, Captain Peggy Carter, King Blackagar Boltagon, Captain Maria Rambeau, Doctor Reed Richards, and Professor Charles Xavier. They explain that through reckless use of his universe’s Darkhold, Earth-838’s Strange triggered, and barely averted a universe-destroying “incursion” and had to be killed before he caused more harm; Mordo believes Earth-616’s Strange is similarly dangerous. Before they can pass judgment, Maximoff arrives and kills the Illuminati, except Mordo. Strange and Chavez escape with help from the Earth-838 counterpart of Strange’s ex-fiancé Christine Palmer, an Illuminati scientist.
Fleeing from Maximoff, the trio enters the space between universes to find the Book of Vishanti, but Maximoff appears and takes over Chavez’s mind, using her powers to send the others to an incursion-destroyed universe. On Earth-616, Maximoff begins the spell to take Chavez’s powers. Strange fights the destroyed universe’s Strange, who has been corrupted by the Darkhold. Strange uses this Darkhold to dream-walk into the corpse of the alternate Strange which remained on Earth-616 and save Chavez. Unable to overpower Maximoff, Chavez instead transports her back to Earth-838, allowing Billy and Tommy to witness her evil. They recoil in fear, crying for their real mother, Earth-838’s Wanda.
Realizing the error of her ways, Maximoff sacrifices herself and uses her powers to destroy all copies of the Darkhold throughout the multiverse. Before Palmer returns to Earth-838, Strange tells her that he still loves his universe’s Palmer but has always been too scared to have a real relationship. Chavez begins training as a sorcerer at Kamar-Taj. Sometime later, Strange develops a third eye as a result of using the Darkhold and is approached by a sorceress,[N 4] who warns him that his actions have triggered an incursion as both enter the Dark Dimension.
