Synopsis for "Where No X-Man Has Gone Before!"
X-Men #107
Transported to another galaxy via stargate, the X-Men (including the Phoenix) find themselves on the ancient and mostly barren planet in the heart of the Shi’Ar Empire. They are in pursuit of their enemy, Erik the Red, who has abducted the alien, Lilandra Neramani.
The Shi’Ar Empire spans its entire home galaxy. Currently, it is ruled over by the insane Emperor D’Ken (Lilandra’s brother). Erik the Red is revealed to be Davan Shakari, a high-ranking Shi’Ar official loyal to D’Ken. Although mostly barren, this world does contain the M’Kraan Crystal, a mammoth and legendary jewel that contains unimaginable power. D’Ken has come here with an entourage of about twenty members of the empire’s Imperial Guard in order to access the power of the Crystal. Legend states that when the stars are aligned in a particular way (as they have just recently done), then the Crystal can be penetrated and its power unleashed.
Shakari has brought Lilandra to be an offering to the demonic “Soul Drinker” beast which lurks upon this world. Cyclops demands that D’Ken hand over Lilandra to the X-Men. D’Ken dismisses him and orders his Imperial Guard to kill the X-Men. A ferocious battle commences. The X-Men hold their own against the Guard, despite the latter team’s much larger number of combatants.
Emperor D’Ken unleashes the Soul Drinker on Lilandra, but Nightcrawler teleports to her rescue and spirits her away to the X-Men’s side of the battlefield. The Soul Drinker therefore takes an unnamed member of the Imperial Guard in her place as its sacrifice. Elsewhere in the war zone, Wolverine’s uniform gets shredded. He finds an Imperial Guardsman named Fang with a similar build to his, knocks him out, and takes his uniform.
Lilandra reveals that D’Ken intends to use the M’Kraan Crystal to gain absolute power. She opposed him and became his enemy and a fugitive of the empire. She explains further that she was first psychically connected to Professor Xavier when he used his mental powers to thwart an alien invasion by the Z'Nox; she journeyed to Earth to seek his aid in the hope that he could aid her resistance efforts.
Inexorably, the X-Men are being overwhelmed by the sheer number of their opponents. But the tide of the battle is turned by the arrival of the Starjammers, a group of interstellar pirates who join the X-Men in battle against the Guard. Phoenix mind-probes their leader Corsair and is shocked by what his thoughts reveal.
Suddenly the M’Kraan Crystal pulsates… and for a fraction of a second, reality ceases to exist! Back on Earth, Peter Corbeau warns the Fantastic Four that should reality suffer more cosmic “blinks”, the universe will be destroyed.

Synopsis for "Armageddon Now"
X-Men #108
Emperor D'Ken threatens to destroy the universe by utilizing the power of the M'kraan Crystal. The X-Men and the Starjammers hurriedly compare notes and determine that when specific stars (actually distant galaxies that appear to be single points of light from the planet’s surface) come into alignment, the crystal can be penetrated. D’Ken intends to enter it so as to access its full power.
On Earth, Peter Corbeau teleconferences with President Jimmy Carter, the Avengers and the Fantastic Four. He relates some grim news: a strange force in another galaxy is threatening to destroy the universe. The Wasp remarks on how helpless she feels when faced with a crisis even Earth's mightiest heroes cannot stop.
On the M'Kraan world, the X-Men approach the crystal and are confronted by its defender, a small android named Jahf, who tells them that, as long as the gate is open, no one may approach the crystal and live. Wolverine mocks the small android, but one punch from Jahf launches him into orbit! Only quick thinking by the Starjammers’ robot pilot Waldo saves him. He teleports Wolverine aboard the ship and into the medical bay. Jahf battles both the X-Men and the Starjammers, easily thrashing them with his superior strength. Brute force doesn't work, so the X-Men pool their abilities to fight the creature. Storm clouds Jahf in a pea-soup fog, allowing Banshee to get close enough to unleash the full fury of his sonic scream. While he manages to destroy Jahf, he strains his vocal chords to such an extent that he can barely talk.
The two teams are immediately attacked by a second guardian of the crystal, a giant robot named Modt, who states that his power is a thousand times greater than Jahf's and that, if he falls, the intruders will face a guardian whose power is a thousand times his. During the fight, the Starjammer Raza finds Emperor D'Ken and assaults him. He inadvertently tosses the despot into the M'kraan Crystal, causing both groups to be transported within.
Inside the crystal, everyone find themselves in a large vacant city. At its center is a sphere of pure light that Phoenix finds herself drawn to. Upon touching it, everyone present is struck by a bolt of energy that awakens in their mind their greatest fears. Phoenix manages to shake off the effect and when Cyclops goes berserk as a result of his hallucinations, she renders him unconscious. The sphere begins to crack, so she channels the full extent of the Phoenix force into it and learns that it is keeping the birth of a neutron galaxy at bay. Should that barrier break, the galaxy will collapse into a black hole large enough to consume the whole of this universe (including the 616 reality and all other timelines and dimensions), destroying it utterly to make way for a new universe.
Phoenix attempts to repair the damage, but even her power is not enough; she needs additional life force energy to help repair the damage. Aside from Phoenix, only Storm and Corsair have been able to fight off the sphere's hallucinatory influence. She convinces them both to give her a portion of their life forces. Phoenix also reveals to Corsair that she knows he is Christopher Summers, the presumed-dead father of Scott (Cyclops), a revelation Storm overhears. Phoenix uses the full extent of her powers to repair the damage. As she works, Corsair approaches an unconscious Cyclops and is shocked to realize he is his son. Slowly, Cyclops is coming round and vaguely hears his words, but doesn’t consciously register them.
With the repairs completed, Phoenix instantly transports all the X-Men back home to Earth via the stargate. Professor X, Misty Knight and the Greys are still there waiting for them. They are also confronted by Firelord, but he explains that he has no quarrel with them anymore after Xavier explained how he was manipulated by Erik the Red. Everyone is surprised, however, when Empress Lilandra comes through the gate as well. The stargate then burns out entirely, ensuring that Lilandra must remain on Earth. She explains to Charles and the X-Men that her brother was consumed by the M'kraan Crystal, and she is now the ruler of the Shi'Ar Empire. However there will be bureaucratic matters to sort out before she can ascend to the throne. Until then, she wants to spend time with Charles on Earth.
