The Chamber of Secrets had never been so alive.
For centuries it had been a tomb of stone and silence, a monument to secrets and serpents, to ambition buried beneath Hogwarts itself. Now it hummed—literally hummed—with power. Ancient runes embedded in the walls glowed in layered colors: silver, violet, deep sapphire. The air vibrated faintly, like the moment before a storm breaks.
At the far end of the chamber, the starship rested.
It no longer looked like a relic.
Panels that had once been dull and cracked now shone with a smooth, dark sheen, reflecting torchlight and rune-glow alike. Lines of alien script pulsed along its hull, awakening one by one as if the ship itself were stretching after a long sleep. From within came a low, steady thrum—deep, resonant, alive.
Harry stood at the base of the loading ramp, hands clenched at his sides, staring.
He had done it.
After years of frustration. After failed equations, collapsed alchemical circles, and fuel prototypes that either evaporated, exploded, or tried to eat fuel tank itself—he had finally done it.
Behind him, Dobby let out a sound somewhere between a laugh and a sob.
"Master Harry," the house-elf whispered, eyes impossibly wide. "The lights… they are listening."
As if in response, the ship's interior lights brightened, responding to Harry's presence. Consoles flickered to life, holographic displays unfolding into three-dimensional projections of star maps Harry had never seen before. Constellations bloomed in the air like frozen fireworks.
Winky clapped her hands so hard she nearly toppled over.
"It works!" she squealed. "Winky told Dobby it would work! Master Harry is genius! Bigger genius than all the wizards with silly hats!"
Dobby barely heard her.
He was already scrambling up the ramp, toolkit floating behind him, ears twitching with excitement as panels hissed open along the ship's interior.
"Dobby must oil hinges!" he announced seriously. "And recalibrate power conduit! And tighten gravity stabilizer—oh, this ship has been neglected terribly!"
Harry laughed softly despite himself.
It felt strange—this moment. He had imagined it so many times. Alone. Silent. Victorious in solitude.
Instead, the Chamber rang with life.
He stepped forward, placing his palm against the ship's hull.
He closed his eyes, remembering the breakthrough.
Voldemort's memories had been the key—the Dark Lord had understood something most wizards never even considered: magic was not infinite. It flowed. It obeyed laws. And if those laws could be mapped…
His own knowledge had provided the missing restraint. Where Voldemort had tried to force reality to bend, He had learned how to let it move.
Harry had stood between those two philosophies and fused them.
The fuel was not a substance in the traditional sense.
It was a reaction.
A stabilized alchemical matrix that converted ambient magical radiation, Force resonance, and kinetic movement into sustained propulsion. It fed on motion, on existence itself—without draining the world dry.
A closed loop.
Sustainable.
Harry exhaled shakily.
"I really did it," he murmured.
A familiar cold-blue light shimmered near the center of the chamber.
The holocron activated.
Darth Bane—Salazar Slytherin—materialized, his spectral form tall and imposing, hands clasped behind his back as he surveyed the ship.
"Impressive," the Sith Lord said slowly. "You have surpassed even my expectations."
Harry didn't look at him. His eyes were fixed on the ship.
"I used your knowledge," Harry said. "And Voldemort's."
Bane's lips curved faintly. "You used your brain. The knowledge was always there. You merely lacked the discipline to apply it correctly."
Dobby popped his head out of an access hatch. "Master Slytherin! The ship likes Master Harry very much!"
Bane's gaze softened—just a fraction.
"As it should," he said. "He is its master now."
The holocron flickered and dimmed, leaving the chamber quieter—but not empty.
Harry climbed the ramp slowly, boots echoing against metal that had not felt a living step in millennia. The interior smelled faintly of ozone and ancient alloys. Consoles responded instantly to his touch, interfaces shifting to accommodate his understanding.
Navigation. Life support. Shields.
All green.
He sank into the pilot's chair, fingers hovering over controls that felt… familiar.
And that was when the doubt hit him.
The excitement faded, replaced by a tight ache in his chest.
He leaned back, staring up at the curved viewport where the stone ceiling of the Chamber reflected faintly.
"This is it," he whispered.
Winky and Dobby froze.
"Master Harry?" Winky asked carefully.
Harry swallowed.
"I can leave now," he said. "The ship is ready. The fuel works. Navigation is stable."
Dobby's ears drooped slightly. "Leave… Hogwarts?"
"Leave Earth," Harry corrected quietly.
Silence fell like a weight.
The reality of it pressed down on him harder than any curse ever had.
Hermione's sharp voice, lecturing him about attendance. Neville's quiet determination. Sirius's reckless grin. Remus's calm, steady presence. Even Hogwarts itself—the corridors, the staircases, the Great Hall at sunrise.
All of it would be behind him.
"There is no guarantee," Harry continued, voice steady but low. "I might travel for years and find nothing. Dead worlds. Empty systems. Ruins."
Dobby climbed down slowly, standing in front of him.
"But Master Harry always wanted stars," Dobby said simply.
Harry smiled sadly. "I did. Before I had people."
Winky stepped closer. "People will still exist, Master Harry. Even if you are far."
He closed his eyes.
The decision had been made long ago—before Hermione, before Neville, before Sirius had become family. Before Hogwarts had started to feel like something he might actually belong to.
If he stayed now, it wouldn't be choice.
It would be fear.
"I'm going," Harry said at last.
Not loudly. Not dramatically.
Just truth.
Dobby straightened instantly, resolve returning. "Then Dobby will make ship perfect."
Winky nodded fiercely. "Winky will pack everything!"
Harry laughed softly, a real laugh this time.
"Thank you," he said.
Building the means to leave the world had been easier than preparing to survive without it.
The romance of the stars faded quickly when reality set in. Space was not a storybook sky filled with wonder and destiny. It was emptiness—vast, uncaring, and lethal to the unprepared. Harry had learned that lesson well from Slytherin's holocron.
"You will not find civilization simply because you wish it," Slytherin had said once, his spectral image pacing slowly around the Chamber. "Most worlds are dead. Many are hostile. Some are beautiful but barren. You must assume nothing."
Harry had taken that lesson to heart.
That was why the second phase of his plan mattered just as much as the first.
Supplies.
Lots of them.
The muggle world was… overwhelming.
Harry stood in the middle of a massive supermarket, fluorescent lights buzzing overhead, aisles stretching endlessly in every direction. Shelves were stacked floor to ceiling with food—more food than most wizarding villages saw in a lifetime.
And it was all so mundane.
No enchantments. Just sheer industrial abundance.
"This," Harry muttered under his breath, pushing a trolley forward, "is why Muggles survived without magic."
He moved methodically, like a general preparing for a long siege.
Canned food first—non-perishables that could last years without spoilage. Beans. Soups. Vegetables. Meat sealed in tins. Rice by the sacks. Flour. Sugar. Salt. Entire shelves emptied quietly into his cart.
Then dried goods.
Nuts. Dried fruits. Jerky. Protein bars designed for hikers and soldiers. Emergency rations meant to last decades. He read labels carefully, calculating caloric density and nutritional balance in his head.
He was planning for years.
Every few aisles, he slipped into a corner, murmured a quiet incantation, and vanished the contents of his trolley into an enchanted trunk linked directly to the Chamber of Secrets. The trunks were masterpieces—expanded internally to the size of warehouses, temperature-regulated, time-stabilized.
Food that went in fresh would remain fresh indefinitely.
Water came next.
That was more complicated.
He couldn't rely on finding drinkable water on another planet, and even if he did, he had no guarantee it wouldn't be toxic. So he bought filters—dozens of them. Portable purification systems. Chemical tablets. Entire crates of bottled water, all vanished discreetly when no one was looking.
Later, he would do better.
Back in the wizarding world, he commissioned specialized trunks from Diagon Alley—custom-made, outrageously expensive, and absolutely worth it. Each one was charmed with self-refilling reservoirs linked to a sealed internal lake Harry had conjured himself. The water within was enchanted to remain pure, constantly refreshed through a cycle of alchemical transmutation.
It wasn't infinite.
But it would last a very long time.
Gold, it turned out, was useless.
"Metals are abundant among the stars," Salazar had explained, his tone almost dismissive. "Gold, silver, platinum—these are common elements. Their value is cultural, not universal."
Harry had frowned at that. "So what do people trade with?"
"Energy. Knowledge. Rare compounds. Technology. Life."
That had settled it.
Harry did not bother hoarding wealth for the journey.
Instead, he invested in self-sufficiency.
Potion ingredients filled three trunks on their own—carefully sorted and preserved. Dried asphodel roots. Powdered moonstone. Bundles of dittany. Phoenix-feather substitutes. Blood-replacement compounds. Antivenoms. Healing draughts. Nutrient elixirs.
He brewed what he could in advance.
Strengthening potions. Bone-regrowth salves. Antidotes for poisons he might never encounter but refused to be unprepared for. Long-term health tonics meant to slow aging and resist disease.
Then came seeds.
That idea had come from an old movie he saw.
"If you find soil," the voice inside his head said, "life will follow."
Harry acquired seeds obsessively.
Wheat. Rice. Corn. Potatoes. Beans. Medicinal herbs. Magical plants too—carefully chosen varieties that could adapt to alien conditions with minimal assistance. He enchanted them lightly, enough to survive harsh environments without becoming invasive nightmares.
Entire greenhouses were packed away into trunk-spaces, complete with soil beds, irrigation charms, and artificial sunlight arrays powered by the ship's core.
He wasn't just preparing to leave.
He was preparing to survive.
The Chamber of Secrets slowly transformed.
Trunks lined the walls in precise rows, each labeled and cataloged. The ship's cargo hold filled steadily, its internal systems adjusting automatically to balance mass and energy distribution.
Dobby worked tirelessly.
"Master Harry must not forget emergency repair kits!" the elf declared one night, dragging a crate twice his size across the floor. "Hull breaches are very rude!"
Winky supervised inventory with near-militant precision, clipboard in hand, muttering numbers under her breath.
"We are short six nutrient packs," she said sternly. "Winky does not like shortages."
Harry smiled at them both, even as something heavy twisted in his chest.
They were excited.
He was… afraid.
Not of space.
Of what he wasn't telling anyone.
Hermione noticed first.
"You're avoiding us," she said one evening in the common room, arms crossed, eyes sharp. "You're here, but you're not here."
Harry didn't look up from the book he was pretending to read.
"I've just been busy."
"With what?" Neville asked quietly.
Harry closed the book.
"I can't tell you yet."
Hermione's jaw tightened. "That's not fair."
"I know."
He finished loading the ship.
Ten massive trunks. Food. Water. Medicine. Seeds. Tools. Spare parts. Clothing. Books—thousands of them, magical and muggle alike. Knowledge copied from wizarding libraries and muggle networks, translated and indexed by the ship's systems.
Fuel cells stacked neatly in reinforced containment units.
Everything ready.
All that remained was the hardest step of all.
Saying goodbye.
Harry stood alone in the Chamber one night, the ship looming before him, silent and patient.
He rested his hand against its hull.
"Soon," he whispered.
The ship's lights pulsed softly in response.
Beyond Hogwarts, beyond Earth, the stars waited—indifferent, vast, and full of possibility.
The Chamber of Secrets was always asleep until someone lit the torches—but tonight, it breathed alone.
Dobby, curled asleep near one of the cargo conduits, twitched as the hum deepened. Winky stirred as well, her ears flicking as if she sensed something old and powerful stretching itself awake. Neither of them rose.
Because something else had.
At the very front of the ship—inside the command cabin—something suddenly pulsed with crimson light.
The holocron.
Placed carefully beside the pilot's chair by Dobby's small hands, the angular crystal rotated slowly in midair, its facets glowing from within. No one had touched it.
Yet it activated.
A column of red light burst upward, flooding the cabin, and a towering spectral figure coalesced above it—solid, sharp-edged, unmistakable.
Darth Bane.
Salazar Slytherin.
Or rather… both.
The figure inhaled deeply, as though drawing breath for the first time in centuries. His eyes—burning, intelligent, hungry—swept across the cabin, lingering on the control panels, the navigation arrays, the star-maps now faintly flickering into existence.
A slow, reverent smile curved his lips.
"At last," he said, his voice echoing with layered resonance—one voice ancient and cold, another sharp with ambition. "At long last."
This holocron was not merely a repository of knowledge.
It had never been.
It was an anchor.
A vessel.
A prison that Salazar Slytherin had willingly entered, biding his time, waiting for a successor worthy enough to finish what he had begun.
And now… the ship was ready.
He extended a translucent hand, brushing it over the pilot's chair, over the controls that answered his presence with a subtle increase in power output.
"The stars," he murmured, almost reverently. "I had nearly forgotten how they call."
The ship responded.
Navigation glyphs flared brighter. A three-dimensional map of nearby star systems bloomed into the air, rotating slowly, ancient hyperspace routes lighting up like veins of fire across the void.
Salazar's expression shifted—from satisfaction to something far more dangerous.
Anticipation.
"For centuries, I ruled through shadows," he continued, pacing the cabin like a conqueror surveying a battlefield. "I shaped empires, bent bloodlines, forged doctrines that still echo in the marrow of this world. And yet…"
His gaze sharpened.
"This planet was always a cage."
A memory flickered behind his eyes—Hogwarts rising stone by stone, the basilisk bound beneath it, the slow realization that magic alone could not take him where he wished to go. That the galaxy—the true arena of power—remained beyond his reach.
Until now.
