July 21, 2557
Core of Requiem
The light bridge held beneath their boots as if solidity were a suggestion it had chosen to humor.
John crossed first.
Lauren followed half a step behind and left, close enough that he could hear the uneven catch under her armor’s filters whenever the path dipped or the bridge hummed underfoot. The hardlight surface gave nothing back. No flex, no grit, no familiar scrape of metal under Mjolnir soles. Just blue-white light stretched across empty air, steady above a canyon that dropped too far into Requiem’s hollow dark.
Below them, machinery breathed.
Or something close enough to breathing that Lauren did not like it.
The sound rose through the gorge in slow pulses, too deep for ordinary hearing, felt more in the armor than in the ear. Far above, the first pylon cut into the manufactured sky, its beam burning upward in a clean line toward the satellite at the world’s center. The beam did not flicker. It did not waver. It looked calm in the way a blade looked calm before it was used.
Lauren kept her eyes forward.
Looking down was not the problem. Heights had never bothered her. Falling into Requiem had done a great deal to offend her personally, but fear of distance was not one of the injuries it had left behind.
The problem was the bridge.
It felt too much like a decision made for her.
“You’re quiet,” John said over private TEAMCOM.
She adjusted her grip on the lightrifle. The weapon floated around its own frame in her hands, hardlight components shifting by tiny degrees as if it were breathing too. She hated how well balanced it was. That felt rude.
“I’m having a disagreement with the bridge.”
“Is the bridge winning?”
“It refuses to debate openly.”
Cortana’s voice came through John’s suit and Lauren’s damaged bridge, faintly doubled at the edges. “Forerunner infrastructure is notoriously poor at customer service.”
Lauren looked toward the pylon. “Everything here is poor at customer service.”
“That pylon is our complaint department,” John said.
“Good. I brought a rifle.”
Cortana gave a tiny laugh. Not clean. Not broken either. It flickered and survived.
They reached the far side.
Stone accepted them again, red-gray and worn smooth in places where Forerunner metal had grown through it in precise black ribs. The path angled up through a cleft in the canyon wall. Beyond the cleft, the terrain opened into a wider valley littered with Forerunner ordnance crates and pale, inert weapon racks folded into the rock. The first pylon loomed ahead and above, far closer now, its lower structures embedded in a cliff face surrounded by smaller support buildings. Hardlight shields shimmered across the upper entrance in stacked planes.
They were not alone.
Crawlers moved over the rocks like spilled knives.
The first pack scattered when John stepped into the valley. Blue spines flashed across stone. Metal claws clicked. Several disappeared into cracks along the cliff wall, too fast and too low, their gun-heads swinging back for quick looks before vanishing again.
Lauren raised the lightrifle. “They’re doing the horrible little retreat thing.”
“They’ll come back,” Cortana said.
“They always do.”
The path narrowed around a central stone pillar. John moved right. Lauren took left. The first Crawler came over the top of the pillar and opened fire before its feet hit the ground. John shot it mid-leap. It broke apart in blue fragments and vanished before the pieces could land.
Then the walls moved.
Crawlers poured down both sides of the canyon. Not many at first. Then too many for the space. They came in quick, angular bursts, leaping between rock shelves, jaws splitting into weapons, boltshot fire cracking blue-white across the valley. John stepped forward to draw the centerline. Lauren slid behind a Forerunner block, took one breath that hurt too much, then started picking them off as they crossed his flanks.
The lightrifle kicked strangely.
Not recoil. Something cleaner, sharper, a pulse traveling up through the gauntlet and into her shoulder. The first shot caught a Crawler in the head and tore it apart in a burst of orange-white energy. The second clipped another along the spine. The third punched through the exposed core when it turned toward John.
Lauren stared at the weapon for half a second.
“I hate that this works.”
“Continue hating productively,” Cortana said.
John’s assault rifle snapped in short bursts. A Crawler tried to get behind him along the right wall. He shot another in front of him, pivoted, and caught the flanker with his sidearm before it cleared the ledge. Lauren dropped two more on the left, then shifted back when a Watcher unfolded from a high niche above the valley.
The drone spread its wings.
A shield bloomed around three Crawlers below it.
Lauren exhaled. “That thing first.”
“I have it,” John said.
“No, I have it.”
The Watcher darted sideways as she aimed, too fast, too clever. She tracked it through the lightrifle’s sight and waited one fraction longer than the weapon wanted. The drone paused to repair a Crawler whose broken body had begun to reassemble in hardlight. Lauren fired.
The shot hit the Watcher’s center.
The drone snapped backward, wings flaring, shield collapsing. John’s next burst finished it. The half-repaired Crawler died under Lauren’s follow-up before it found its legs.
The valley quieted.
John reloaded.
Lauren lowered the rifle just enough to breathe.
Her chest had gone from fire to something deeper, a steady bruising pressure under the damaged plate. Cortana’s medical bridge shifted softly along her suit’s inner architecture, adjusting support through the spine and shoulder lock instead of cinching the chest. Better than before. Still not enough.
John looked at her.
She lifted one hand before he asked. “Six. Maybe seven if the planet insults me again.”
“It will,” Cortana said.
“Rude but fair.”
John looked toward the path climbing out of the valley. “Those weren’t the same things we saw in the Terminus.”
“Similar cortical footprints as the Tower AIs,” Cortana said. “They’re connected, all right.”
Lauren glanced at the blue fragments fading from the last Crawler. “Cortical footprints.”
“Yes.”
“That’s a brain word.”
“It is.”
“They’re machines.”
“Apparently, Forerunners enjoyed making categories difficult.”
The answer sounded like Cortana. It also sounded like Cortana choosing a useful puzzle because useful puzzles did not ask her whether she was dying.
John heard that.
He moved on.
The next path curved upward along the cliff, passing beneath arches of black Forerunner metal. At the top, the valley broadened again, and the first relay structure came into clearer view. The pylon’s base rose in layers of stone and metal, shielded by hardlight barriers that blocked the main ramp. Smaller buildings sat around it like anchors, each one feeding power into the shield system through bright energy lines under the ground.
Lauren saw the lines.
Not with the HUD.
With something lower.
A pressure moved under her chest plate, tracking the energy through the stone. It was not language. Not direction exactly. But when she looked left, she knew there was power there before Cortana marked it.
She stopped.
John stopped with her.
“What?”
Lauren looked toward the nearest structure, half-hidden behind a rock shelf. “Power source.”
Cortana paused. Then a marker appeared in the same place.
“How did you know that?”
“I saw the line.”
“I didn’t send the schematic yet.”
“I know.”
John’s visor stayed on Lauren for one beat too long.
She did not look at him.
The energy under the ground pulsed again, and the old Spark wound answered with a cold ache that made her fingers tighten around the lightrifle. She wanted to say she was fine. She did not. Progress, apparently, looked like silence with better manners.
Cortana’s voice came low. “That’s the target, but it looks like the entrance is shielded. Let’s figure out how to take it down.”
John started toward the smaller structure.
Lauren followed.
The first Knight appeared on the far ledge.
It did not drop this time. It watched.
Tall, angular, blue-lit, with a weapon held low and its face sealed into that smooth mask that looked almost merciful until it opened. Two Crawlers crouched near its feet like hounds. A Watcher hovered behind its shoulder.
John raised his rifle.
The Knight tilted its head.
Then it vanished.
Lauren hated that more than a charge.
“Where?”
“Left,” Cortana snapped.
The Knight reappeared beside a Forerunner pillar near the power structure and fired. Hardlight rounds tore across the path. John took the first volley on his shields. Lauren moved right, using the rock shelf for cover, and fired at the Watcher before it could shield the Knight.
The Watcher darted upward.
Lauren missed.
The shot struck the pylon wall and vanished in a flash of orange.
“Bad start,” she muttered.
“You’re breathing too shallow,” Cortana said.
“I’m aware.”
“Then breathe differently.”
“I am accepting suggestions from people with lungs.”
Cortana went silent for a fraction.
Lauren cursed herself before the silence finished forming.
“Sorry,” she said quickly.
The Knight fired again.
John pushed forward under fire, giving Lauren the moment she needed to correct the shot. She inhaled carefully, pain clawing under the chest plate, and took the Watcher as it dipped to project a shield. The lightrifle round punched through one wing. John finished it with a burst from the assault rifle.
The Knight snarled.
Its face split open.
That blue skull-shape glowed underneath, disturbing not because it was human, but because it was close enough for the mind to notice the resemblance before rejecting it.
Cortana’s voice came thin. “From that peek under the hood, I’d say these constructs must be mimetic in nature.”
Lauren fired at the exposed light. “Meaning what?”
“Meaning they may be modeled after something living.”
The Knight teleported.
John pivoted.
It appeared behind Lauren.
Not on her injured side. Worse. Directly behind.
John moved before the machine fully reformed. Lauren saw his motion and dropped to one knee without asking why. The Knight’s blade swept through the space where her helmet had been. John hit it from the side and drove it into the wall hard enough to crack its shield.
Lauren fired upward from the knee.
One shot into the cracked shield.
Another.
The third hit the glowing seam at its waist.
The Knight staggered, vanished, and reappeared on the high ledge where it had started.
John threw a grenade.
The blast caught the edge of the ledge, forcing the Knight back. Lauren fired as it moved. The lightrifle round struck center mass. The shield failed. John switched to the Forerunner suppressor he had taken from the previous basin and poured hardlight fire into the exposed core.
The Knight collapsed.
This time, as it dissolved, a flash of blue-white data flared out from the body.
Cortana reached for it.
John felt her do it through the neural interface: a sharp pull, hungry and involuntary, like a hand snapping toward falling glass.
“Cortana.”
“I’ve discovered something interesting about our new friends,” she said, too focused to hear the warning yet. “When the big ones explode, that momentary flash we’re seeing is actually a data purge.”
A schematic opened across John’s HUD.
Knight anatomy. Hardlight frame. Core housing. Something like neural architecture.
Lauren saw part of it through Cortana’s bridge and immediately wished she had not. The diagram did not look like a machine. Not entirely. It had too many echoes of body inside it. Too many choices shaped around a ghost of musculature and rage.
John’s voice stayed even. “Can you tap into it?”
“So far, I’ve pulled multiple strings referring to the big ones as Promethean Knights.” Cortana paused. “Beyond that, though, things get a bit dense.”
Dense.
The word arrived wrong.
Lauren heard it catch. “Cortana?”
“I’m fine.”
“No.”
Cortana did not answer.
John entered the first power structure.
The inside was small, circular, and lined with floating panels. At its center hovered an energy sphere, bright orange-white, bound in place by rotating hardlight rings. Power ran from it through the floor, out toward the shield blocking the pylon ramp.
Lauren stopped at the threshold.
The sphere pulsed.
Her chest answered.
This time the pain was not cold.
It was recognition turning hot.
She stepped back.
John saw. “Lauren.”
“Power core,” she said, too fast. “Take it out.”
Cortana’s voice sharpened. “One of the shield’s power cores. Take it out.”
John fired.
The core shattered in a burst of light.
The building shook. Outside, one layer of hardlight shielding over the pylon flickered but did not fall.
Cortana marked two more structures. “I read two more cores on our level. Hit them before you climb all the way up.”
Lauren looked toward the second marker. “Of course there are three.”
“Forerunners liked symmetry,” Cortana said.
“They liked making people walk.”
John stepped out of the structure. “Move.”
The second core sat across a depression filled with broken stone and Forerunner ribs. Crawlers swarmed the lower floor before the Spartans reached the first ramp. They came in two packs, one low, one high, moving with irritating coordination. John took the upper wall. Lauren took the lower path, using the lightrifle for precision and the battle rifle when anything got too close for patience.
Halfway across, purple static slashed through John’s HUD.
Then Lauren’s.
The world tore sideways for a fraction of a second.
Not visually. Internally.
John saw the canyon and then a white room. Halsey’s observation glass. Small hands. Lauren’s name on gray fabric. His own. The image snapped away before he could catch it.
Lauren staggered.
Her shoulder hit a Forerunner pillar.
John turned instantly. “What was that distortion?”
Cortana did not answer.
Purple static crawled across the lower half of his visor, then cleared.
“Cortana.”
“…that’s me,” she said.
The honesty landed bare.
No joke first. No deflection.
“Something about moving through those portals is increasing the load on my systems.”
John kept his rifle raised but shifted closer to Lauren. “Are you going to be all right?”
Cortana laughed once.
It had a bad edge.
“Don’t worry. I’ve held off rampancy this long, haven’t I?”
Lauren’s helmet turned toward John.
He heard everything beneath the line. The fear wrapped in bravado. The word rampancy placed in the open, then immediately stepped around. A wound named like naming it might make it behave.
“Cortana,” Lauren said.
“I said don’t worry.”
“That has never worked once in human history.”
“I’m not human.”
“No,” Lauren said softly. “But you’re still very bad at that sentence.”
The next Crawler leaped before Cortana could answer.
John killed it.
Lauren pushed off the pillar and fired at another climbing down from the right wall. The moment passed because combat took it. Combat was very good at stealing emotional conversations and leaving the receipts buried in blood.
They cleared the depression and entered the second core structure.
This one reacted to Lauren before John touched anything.
The rotating rings around the energy sphere slowed.
The light inside compressed toward her, narrowing as if focusing.
John raised his rifle at the core.
Cortana’s bridge in Lauren’s armor flared bright enough to show through the damaged chest seam.
“Back,” John said.
Lauren obeyed for once.
That worried him more than argument would have.
She retreated two steps through the doorway. The core’s light loosened. Its rotation resumed.
Cortana’s voice went quiet. “It’s reading the residual Forerunner energy in the wound.”
“Spark’s beam,” John said.
“Partly.”
Lauren stood outside, hand tight around the lightrifle. “Partly?”
Cortana did not answer fast enough.
John destroyed the core.
The second shield layer flickered and failed.
“Well done, Chief,” Cortana said, and her voice sounded nearly normal again. “One to go.”
Lauren stepped back into the open.
John did not move until she did.
“I’m okay.”
He stared.
“I am not okay,” she corrected. “But I’m not worse.”
“Your standards are moving.”
“So am I.”
He accepted the answer because he had to.
The last core was guarded.
Two Knights this time. One on the upper platform, one near the core building. Watchers circled between them like spiteful little surgeons, repairing Crawlers, projecting shields, throwing grenades back whenever John used them. The fight became slower and uglier than the others.
John took the upper Knight first.
It teleported every time he broke its shield, reappearing behind stone or above him on ledges. Lauren watched its pattern for three cycles, then stopped shooting at the Knight entirely and shot where it was going to arrive. The lightrifle round hit it as it reformed, staggering it out of phase. John followed with suppressor fire and drove it backward into the open.
The Watcher moved to shield it.
Lauren shot the Watcher.
This time she did not miss.
The drone broke apart.
The Knight died badly.
The lower Knight rushed Lauren.
Not John.
Lauren saw it choose her.
So did John.
The choice put cold into him.
The Knight teleported once, twice, closing distance in jagged blue flashes. Lauren fired until the lightrifle overheated. She switched to the battle rifle, backed up, and deployed the hardlight shield with her left hand. The shield unfolded just as the Knight’s blade struck.
The impact shattered the hardlight plane.
The force drove Lauren backward into the core building wall. Her damaged chest plate hit first.
Pain erased the room.
For half a second she heard nothing but her own body protesting too loudly to be processed as sound. Cortana’s medical bridge seized around the injury, then loosened before Lauren could gasp against it. John was there before the Knight could strike again.
He did not fire first.
He hit it.
The blow drove the Knight sideways. It turned on him, face splitting open in a scream of blue light. John stepped into the scream and slammed the butt of his rifle into the glowing faceplate hard enough to crack the exposed inner structure. The Knight tried to teleport. Lauren fired one-handed from the wall and struck its core as it began to phase.
The teleport failed.
The machine flickered.
John planted a grenade in its chest.
“Down,” he said.
Lauren dropped.
The Knight exploded.
Blue-white fragments sprayed across the structure. The data purge flashed bright enough to wash the walls. Cortana reached for it and stopped herself halfway, a sharp restraint John felt like a flinch inside his armor.
Good, he thought.
Then hated that there had to be a good.
Lauren stayed on one knee.
John crouched beside her. “Report.”
She lifted her head.
The purple visor reflected him, the core, the pylon beam, and a little of the blue light Cortana had left along her damaged armor.
“Bad,” she said.
He waited.
“Eight. Actual.”
Cortana spoke softly. “She needs less movement.”
Lauren made a small, pained sound that might have been a laugh. “I need a lot of things.”
“Can you destroy the core from here?” John asked Cortana.
“No. Physical damage to the energy sphere.”
John stood and entered the last structure alone.
The core inside pulsed faster than the others. The energy line beneath it ran straight toward the pylon ramp, bright and thick. He fired until the sphere cracked, then drove a final shot into the exposed center.
The core burst.
The last layer of shield over the pylon ramp failed in a cascade of light.
Cortana’s voice returned, urgent. “Great, that’s all the cores. Head for the top of the pylon.”
John came back out.
Lauren was already standing.
He did not comment.
That was mercy.
She knew.
They climbed.
The main structure rose in wide, angular ramps around the pylon’s base. Hardlight strips lit under their boots, one by one. Requiem’s hollow sky opened above them with the satellite still hanging at the center, one beam from this pylon still burning upward while the second shone from far across the core. The closer they got to the top, the worse the interference became.
Del Rio’s transmission fought through static in broken pieces.
“This is Captain Andrew Del Rio, hailing any survivors of the UNSC Forward Unto Dawn…”
The signal stuttered.
The image appeared on John’s HUD for a second: a man’s face, command frame, UNSC feed distortion. Then the orange glyph flashed over it.
The same symbol from the Cartographer.
The one that made the room go cold.
Lauren’s chest wound flared.
John reached for her before she fell.
She did not fall.
Barely.
“Did he say Forward Unto Dawn?” John asked.
“They must have intercepted our distress beacon,” Cortana said.
John looked toward the open core around them. “The beacon was pulled into Requiem with us. If they try to follow it…”
“They’ll get caught in the gravity well.” Cortana’s voice sharpened toward panic. “I’ll keep trying to warn them. You just get that beam down.”
Two Knights phased into existence on the ramp above them.
No time.
John and Lauren moved.
The first Knight brought a scattershot up. John slid behind a Forerunner block as the blast chewed glowing scars through the edge. Lauren took the right, slower but precise, lightrifle raised. Her first shot hit the Watcher emerging from behind the second Knight. It staggered but did not die. The Watcher projected a shield. Lauren fired again into the emitter point. The shield broke. John threw a grenade through the gap.
The second Knight teleported away from the explosion.
It reappeared beside John.
Lauren shot its weapon arm before it fired.
John finished it at close range.
The first Knight rushed her.
John was too far.
Cortana made a sound of alarm and pushed through Lauren’s suit bridge, not locking the armor this time, but feeding the movement compensation along the lower spine and hip joint. Enough for one step. Enough for Lauren to pivot without tearing the chest wound wider.
Lauren felt the support arrive and trusted it.
She stepped inside the Knight’s swing, not away.
The blade passed behind her shoulder.
She put the lightrifle against its torso and fired.
The shot punched into the cracked shield.
John’s next burst broke it.
The Knight dissolved under combined fire, data purge flashing and vanishing before Cortana touched it.
Lauren turned toward the last ramp.
“Good save,” she said.
Cortana’s answer came quiet. “You told me not to replace the compensation.”
“You didn’t.”
“I wanted to.”
“I know.”
The elevator waited at the top of the ramp.
John stepped onto it first, then turned back.
Lauren came up beside him. She was moving more carefully now, not pretending it was anything else. That honesty had edges. It helped. It hurt too.
The elevator rose.
The beam chamber emerged from below like the inside of a weapon.
At the top, the pylon’s emitter dominated the space: a rotating mechanism projecting the energy beam upward through a circular aperture, all orange-white light and controlled violence. The beam struck the satellite far above. A console stood directly in front of the emitter, built around a metal shaft set vertically into a hardlight housing.
Cortana’s voice cut through the interference. “That’s the beam control.”
John moved to it.
The chamber trembled under the beam’s force. Up close, the energy made every armor system complain. Lauren hung back near the elevator entrance, rifle up, watching the doors and the beam and the way John’s outline blurred against the light.
He seized the metal shaft inside the console.
It resisted.
He pulled harder.
The mechanism tore upward with a heavy metallic grind. He rotated the shaft horizontal, then drove it back down into the console.
The beam died.
Not all at once. It fractured. The column of light broke into segments, each one collapsing into the emitter until the pylon’s top went dark. The whole structure shuddered. Far above, half the energy field around the satellite dimmed.
Cortana’s voice came through, brighter with relief. “It’s working. The signal from the relay is starting to clear up.”
Del Rio’s transmission sharpened.
“FLEETCOM Actual, we’ve detected a UNSC beacon coming from somewhere inside the planet…”
John looked toward the core.
“They haven’t hit the gravity well yet.”
A portal opened on the far side of the chamber.
Cortana’s urgency returned immediately. “There’s still too much interference to warn them. We’ve got to disable that other beam before they’re pulled in like we were.”
Lauren stepped toward the portal, then stopped beside John.
For one second, the chamber was almost still.
The first beam was down.
Infinity was not safe.
Cortana was not safe.
Lauren’s chest burned under broken armor, and the word Shadow still had Halsey’s fingerprints on it.
John looked at her.
She knew the question before he formed it.
“Yes,” she said.
“You don’t know what I was going to ask.”
“Yes, I do.”
“Say it.”
Her shoulders rose and fell once, carefully. “I can keep moving.”
John’s visor held hers.
“Actual.”
She paused.
“Barely,” she said.
That was the truest thing she had given him since the fall.
John stepped closer. He lifted one hand and set it against the side of her helmet. Not the mouth. Not the Spartan kiss. Not here, not now, not with the mission clawing at them and Cortana between their systems like a blue nerve. Just his palm against her helmet, steady enough to be a wall, brief enough to remain Spartan.
Lauren did not lean into it.
She did not need to.
Her hand came up and closed once around his wrist.
Cortana watched.
No file opened this time.
No Halsey note. No clinical tag. No poisoned label.
Just two armored figures standing in the dying light of a relay chamber, touching because the world had tried to make touch impossible and failed.
Cortana let herself see it without translating it.
That hurt too.
But it hurt differently.
John lowered his hand.
Lauren released his wrist.
“Second beam,” he said.
“Second beam,” she answered.
Cortana marked the portal.
“Go,” she said.
They went.
