The ground moved first.
Not in the gradual, building way of a natural tremor, but all at once, a single violent heave that traveled through every structure in the Chernobyl exclusion zone simultaneously. The pink-tinted air, thick with gamma radiation held visible by Nova's power, shuddered as the shockwave passed through it. Thunder cracked where there were no storm clouds, the compression of displaced air finding no better word for itself. Masonry buildings that had already been weakened by decades of neglect and recent combat finished the process they had been working toward, their walls folding inward, their roofs coming down, dust rising in grey columns from every direction.
Above all of it, the magnetic hum deepened until it was less a sound and more a pressure felt behind the teeth.
The Chernobyl Nuclear Power Plant occupied several square kilometers of ground. Its foundations ran deep, reinforced over decades of construction and modification, the weight of its reactor structures and surrounding infrastructure anchored into the earth by concrete and rebar and the sheer accumulated mass of everything built on top of it. The metal castings that formed the chassis beneath its foundation were not meant to move.
They moved.
An invisible grip closed around the entire structure from above, vast and precise and utterly unhurried, and the plant began to rise. Sand and gravel poured from the underside of the lifting foundations in quantities that would have buried a city block, streaming downward in curtains as the structure climbed. The noise of it was immense, the combined roar of tearing earth and grinding concrete and the deep, low complaint of metal under impossible stress.
From the cavity left behind, something emerged.
Its overall shape was that of an inverted pyramid, its widest point at the bottom and its narrowest pointing upward, a structure the height of a tower block that had been buried with its apex facing the sky. It was pulled free of the earth with the same unhurried, absolute force that had lifted the plant, dragged upward through the cavity in a cascade of wet soil and fractured stone, and then released.
It hit the ground with enough force to level everything still standing nearby.
The shockwave from the impact flattened the last of the intact structures in the immediate area. Dust and debris billowed outward in a ring. The sound arrived a fraction of a second after the impact, a concussive boom that rolled across the entire exclusion zone.
Then the nuclear plant descended.
The vast structure, suspended hundreds of meters above its original position, came down with the same controlled deliberateness, its enormous mass dropping into the open cavity left behind, filling it completely, sealing the underground complex beneath several thousand tonnes of reinforced concrete and reactor infrastructure.
Simple. Final. Overwhelming.
Whatever else one might say about Magneto, the man understood how to close a chapter.
On the Helicarrier's bridge, the old man exhaled.
It was not a quiet sound. The breath came out rough and unsteady, forced past a body that had just spent more than it was comfortable spending, and his hand dropped to the edge of the cockpit with a tremor he did not bother to conceal. The veins across the back of it stood out sharply against the pale skin.
The middle-aged woman with the orange-red hair moved immediately, crossing the bridge toward him with an expression that had shed its earlier composure entirely.
Magneto raised one hand to stop her, palm out, and she halted. He took a moment to gather himself, the color slowly returning to a face that had gone nearly grey, and then he smiled.
"I am getting old," he said, and there was genuine humor in it alongside the admission. "I remember when burying that prison the first time required considerably less effort. Time is not kind." He turned the cockpit to face Bucky, whose expression had cycled through shock and arrived somewhere approximating controlled alarm. "Well, young comrade? Does that satisfy you? Tell your leader that I have extracted the source of this disaster from the ground for him. His people will not need to waste time navigating the underground complex."
Beside Bucky, Thor had both hands on Mjolnir and the look of someone restraining genuine enthusiasm with considerable effort.
Bucky spoke first.
"I am a captain with some biochemical and mechanical enhancements. I cannot match what you just did." He kept his voice level, without deference and without challenge. "But I want to say clearly that the Guardians of Terra and the Inquisition have already extended considerable goodwill toward the mutant community. This disaster occurred on your soil. We chose to enter it and fight on your behalf. If we had not, the cost to your people would be far greater than it already is."
Magneto regarded him for a long moment.
"You are correct," he said at last, and his tone carried no sarcasm. "Which is precisely why I came in person rather than sending a representative. It is a form of respect." He settled back slightly in the cockpit. "I think, however, that this is not the moment for the two of us to discuss what we owe each other. When everything here is settled, I would like to meet your leader Nolan as the representative of the mutant community. Face to face."
Bucky nodded once.
"Lord Primarch will look forward to it."
He was already turning toward the crew stations.
"All servo units, attend. On my order, begin deploying the Automata Corps to the surface."
Nolan came up through the ground.
He pushed through a web of fractured concrete and tangled rebar, the pale gold of his vibranium armor caked in grey dust, and pulled himself out of the collapse hole into the open air. Around him, the others were emerging from the debris in ones and twos: the Stormseer of the White Scars extracting himself from beneath a fallen wall with measured patience, the Raven Guard champions pulling slabs off each other with the efficient cooperation of warriors who had been buried and unburied before. Further out, the two Knight Dominus suits heaved themselves upright from the rubble that had swallowed them to the waist, their engines surging back to full power, sensor arrays sweeping the ruined landscape as the pilots ran damage checks.
Nolan straightened and looked up.
The Helicarrier was a dark shape against the overcast sky, enormous and motionless at a thousand meters, held in place by a force that was absolutely not its own engines.
"You don't even need to guess," he said, and his voice had enough edge to fill the skull helmet. "There are not many mutants on this planet who can move metal at that scale. And if the man insists on an entrance like that, he could at least have warned the people standing below first."
He shook his head once and looked at the devastation around him. A few minutes earlier, the sudden magnetic surge had trapped everyone within range, the collapsing structures and the invisible grip of the field pressing down from above catching them where they stood. Being sealed underground inside a vibranium power suit was an experience he did not intend to repeat.
He let the irritation pass. Irritation was a poor tool for clear thinking.
The calculation was not difficult. An Omega-level mutant with direct authority over every piece of metal technology ever constructed was not an opponent he could overcome with a fleet. Magneto's power was not merely combat-capable; it was inherently superior to any technological response, because the tools used to fight him were made of the very material he controlled. The Carcharodons fleet could be in orbit above this world and it would change nothing for a man who could redirect planetary magnetic fields.
The Emperor's Great Crusade had unified Terra through force, but it had required the combined weight of entire Legions and the will of a being whose power was categorically beyond anything in this universe.
Nolan had neither here.
"With mutants, the only viable path is diplomatic alliance," he thought, watching the dust settle across the ruins. "Force alone would have earned nothing but enemies I could not actually defeat."
He was, he allowed quietly, fortunate that he had already understood that before today's demonstration.
Then the sound reached him from across the debris field.
The inverted pyramid of the underground prison lay where Magneto had thrown it, its vast metal flanks half-buried in rubble, its reinforced walls meant to hold exactly the kind of individuals who were now apparently reconsidering their situation. It should have been quiet. Whatever remained inside had been behind gamma containment systems, reinforced walls, and several layers of specialized structural engineering.
The metal shrieked.
Not the passive sound of a structure settling under its own weight. Something was tearing through it from the inside, working outward with force that made the entire pyramid shudder against the ground, a rhythmic, escalating series of impacts that sent fresh cracks racing across the exposed surface with every strike.
Something in the prison was still alive.
And it was getting out.
