Broadsword F-41, beneath Mantle’s Approach’s shields
The Broadsword did not fly so much as survive forward.
John kept the fighter tucked beneath Mantle’s Approach’s shield envelope with both hands locked on the controls and every warning light in the cockpit arguing with him. The Didact’s ship filled the canopy above them, not like a vessel, not even like a city, but like the underside of a continent made of black armor and old judgment. Orange light moved through its seams in slow, deliberate pulses, the glow crawling across impossible plates and recessed structures as if the whole warship had a nervous system and had just begun to notice the insect beneath its skin.
The Broadsword was that insect.
A dangerous one.
But still very small.
Lauren sat in the rear weapons station, harness locked across her lavender armor, hands over the targeting controls. The station had been a field modification, probably meant for a weapons officer in an emergency, not a Spartan-II in full Mjolnir managing cannons and missile locks while the ship screamed through the wake of ancient Forerunner engineering. The cockpit lights threw hard reflections across her purple visor. The repaired scar on her chest plate remained visible only when the console glow hit it at the right angle, a dark thread over lavender, no longer a wound and no longer a thing anyone needed to check.
It was just there.
Part of her silhouette now.
Part of the story metal told after bodies had gone quiet.
Cortana’s voice lived everywhere inside the Broadsword: navigation, shields, weapons, comms, reactor feed, the ragged interface between human fighter and Forerunner warship. She sounded steadier when she had systems to hold. Not better. Steadier. Like a breaking hand gripping a rail.
“Broadsword’s hull integrity is stable,” she said. “We’ll be safe as long as we stay below the Didact’s shields.”
Lauren looked at the shield-stress readout screaming yellow at the edge of her board. “Your definition of safe is wearing a fake mustache.”
“It’s relative.”
“Relative to what?”
“Exploding.”
John angled the fighter down through a channel between two enormous armor ridges. The Broadsword’s shields brushed the upper edge of the Forerunner hull and flared white-blue across the canopy. Warning tones shrieked.
Lauren did not move except to kill the first turret that unfolded from the right wall.
The cannon burst punched into a glowing orange node, and the defense turret vanished in a blossom of hardlight and metal.
“Relative,” Cortana repeated tightly.
John said, “Where’s the Composer?”
“Close,” Cortana answered. “I should be able to guide us to it.”
The Didact’s voice entered the cockpit.
Not through speakers.
Not over the Broadsword’s comm.
It was simply there, pressing through the hull, through the shields, through the altered places the Librarian had left inside John and Lauren both.
“You have not been Composed. Such inoculation should not have been possible.”
Lauren’s hands tightened once on the weapons controls.
John’s course did not waver.
Cortana’s avatar flickered across the center display, small, blue, and furious. “Locking onto his transmission.” A burst of static tore through the panel. “He’s at the Composer. We can take them both out at once.”
A target marker appeared far ahead, buried somewhere inside Mantle’s Approach’s superstructure.
Lauren stared at the distance indicator.
It kept changing.
Not counting down cleanly. The Forerunner ship’s internal geometry was shifting under them, recalculating paths, closing corridors, opening false routes, trying to make distance into a weapon.
“That number is lying,” she said.
“Yes,” Cortana said. “So am I, technically. The ship is too large and too dynamic for the Broadsword’s sensors to model accurately, so I’m making educated threats.”
John pushed the throttle.
“That works.”
“It better.”
The first trench opened ahead.
It was not a trench in any human sense. It was a canyon cut through the armor of Mantle’s Approach, wide enough for a squadron of Longswords at the mouth and narrowing in jagged, shifting segments as it descended toward the ship’s interior. Its walls were alive with defense emplacements, beacon nodes, moving armor slabs, and hardlight fields that flickered into existence and vanished again with no visible pattern. Streaks of slipspace residue still stretched across the far reaches of the hull, blue-white scratches in the sky beyond the ship’s shields.
John drove them into the trench.
The world became walls.
The canopy filled with black Forerunner plating to the left, to the right, overhead, beneath. Open space disappeared behind them. Earth vanished for the moment. The only sky left was the narrow slit between upper armor ribs and the warped shimmer of Mantle’s Approach’s shield above.
Turrets unfolded along both walls.
Cortana flooded the HUD with markers, then immediately stripped half of them away. “Too many. Lauren, I’m routing priority targets to your station.”
Lauren’s display snapped into focus: beacon nodes, turret clusters, moving plates, shield locks. She selected the first beacon glowing orange at the trench mouth.
“Target.”
John leveled the fighter just long enough.
Lauren fired.
The Broadsword’s cannons hammered through the beacon’s outer shell. It cracked, flared, and detonated. The hardlight gate ahead rippled and went down.
John slipped through the opening before the ship could decide to close it again.
“First gate down,” Cortana said. “Another ahead. Moving walls.”
Armor plates shifted across the trench, sliding from either side in great black slabs. They did not slam shut all at once. They moved with horrifying precision, leaving gaps that opened and closed like a sequence of jaws.
Lauren tracked another beacon on the left wall.
The fighter tilted hard as John threaded through the first gap. Her targeting reticle slid off the beacon. She waited. Let the ship roll. Let the next wall pass close enough to paint half her display in collision warnings. Then fired.
The beacon burst.
The second gate collapsed.
A turret on the upper right came alive and fired a hardlight stream across the Broadsword’s nose.
John dipped beneath it.
Lauren killed the turret with missiles.
The explosion washed the trench wall in white light. Debris scattered across the fighter’s shields, pinging like rain made of knives.
“Clean,” John said.
Lauren’s mouth twitched behind the visor. “That sounded almost enthusiastic.”
“It was accurate.”
Cortana cut between them, sharper than necessary. “Third gate. Lower beacon. Please save the flirting for a corridor that is not trying to mulch us.”
Lauren found the lower beacon, tucked beneath a lip of armor with barely enough angle for a shot. John rotated the Broadsword by a fraction, just enough to expose the underside of the fighter to the trench floor.
The reticle turned red.
Lauren fired.
The beacon ruptured.
The gate opened.
Then the trench dropped.
The fighter plunged into a vertical descent between two Forerunner plates so close that Lauren’s proximity alarms became one continuous scream. John kept the nose down. Mantle’s Approach’s internal lights streamed past them in orange lines. For one breath the Broadsword seemed less like a ship and more like a bullet falling through a barrel.
A defense craft rose from below.
Not Covenant. Not exactly Promethean. A sleek Forerunner drone, blade-shaped, with a hardlight core and weapon fins unfolding as it climbed. Then another. Then six.
Cortana’s voice tightened. “Automated interceptors. Fast.”
Lauren took over the weapons board fully. “Mine.”
The first interceptor came straight at them.
She fired the cannons in a short, brutal burst. The craft split apart before it reached the nose. The second cut left. John rolled the Broadsword, giving her a line. She fired missiles. The explosion hit two interceptors and threw fragments into a third. A fourth slipped behind them.
Rear warning.
Lauren switched to aft pulse fire and killed it on instinct.
Cortana said, “I’m updating your profile to include unreasonable multitasking.”
Lauren tracked another target. “Put it next to charming.”
“There is no charming category.”
“Make one.”
John pulled the Broadsword out of the descent and into another trench.
This one was wider and worse.
The walls bristled with particle cannons, not full-sized ship killers, but enough to tear the fighter apart if they held a lock. Blue-white beams lanced across the corridor, some fixed, some sweeping, some pulsing in patterns too clean to be random and too fast to be comfortable. The Broadsword’s shields flashed every time a near miss brushed the envelope.
John flew through the gaps like he was reading a language written in violence.
Lauren watched his course while killing everything Cortana marked. It was an old, almost unfair rhythm. John moved the fighter into angles that should not have existed, and Lauren made sure those angles stayed unoccupied by anything alive or automated enough to disagree. Cortana mapped what she could, lied to the ship where she could not, and held their systems together with blue-threaded teeth.
A beam crossed too close.
The right shield quadrant collapsed.
Cortana rerouted instantly. “Right shield compromised.”
John banked left.
A turret opened directly ahead.
Lauren fired cannons.
The turret shield flared and held.
“Shielded,” she snapped.
“Beacon below,” Cortana said.
John dropped the fighter a meter.
That was all Lauren needed.
She fired a missile into the beacon beneath the turret cluster. The shield failed. Her next cannon burst tore the turret apart. John pulled up through the falling debris as it scattered across the trench floor.
The Broadsword scraped a hardlight field.
The cockpit flashed blue.
For one split second, Lauren’s console filled with something that was not targeting data.
Ivanoff.
Orange light.
Tillson’s face coming apart into fragments.
A coffee mug with a cracked handle.
A voice asking whether someone named Mara had made it to Bay Seven.
Then the display snapped back.
Lauren’s finger had frozen a fraction above the trigger.
A turret survived long enough to fire.
John jerked the fighter sideways. The shot burned across their left wing shield and tore plating from the edge.
“Lauren,” he said.
Not sharp.
Here.
She fired.
The turret died.
Cortana’s voice came small through the noise. “That was me.”
Lauren swallowed once. “I know.”
“I’m trying to keep the Composer residue dampened.”
“Keep trying.”
“I am.”
The next gate was closing.
John pushed the Broadsword faster.
A beacon sat at the center of the gate mechanism, protected behind three rotating hardlight rings. Lauren fired. The outer ring took the first burst. She switched to missiles, but the lock slipped as the gate shifted. Cortana adjusted the targeting envelope manually and held it in place.
“Now.”
Lauren fired.
The missile punched through all three rings and struck the beacon core.
The gate shattered open.
John took them through.
The streaked slipspace residue outside the shield vanished abruptly.
Stars returned.
Earth filled the upper gaps in the armor.
Blue. White. Green. Alive.
The trench opened into a broader channel, and the planet hung beyond Mantle’s Approach’s hull, enormous and close enough to make every warning light feel petty. Orbital defense platforms moved in formation beyond the Didact’s shields. UNSC ships swarmed in the distance, their drive flares bright against the dark. MAC rounds streaked toward Mantle’s Approach and burst uselessly against the exterior shield in orange-white blooms.
Cortana’s voice dropped. “We’ve arrived at Earth.”
No one said what all three of them already knew.
The Didact had made it.
Now everything became about whether they could stop him before the Composer fired.
Earth Orbital Defense traffic flooded the comms.
“Hostile inbound! Proceed to Condition Red!”
“MAC defense ineffective against enemy vessel!”
“It’s still approaching.”
“FleetCom, we are reading a massive Forerunner signature above North America.”
“Civilian evacuation orders pending confirmation.”
“Pending? Look at the sky, damn it!”
The comms overlapped until words became a crowd.
Cortana carved through them with a hard blue line. “I’m trying to raise Infinity.”
John kept the Broadsword low in the trench. “Do it.”
Lauren’s targeting board refreshed. “More defense nodes ahead.”
The next section was less open trench and more corridor inside the outer hull, broken by windows of exposed shielded space where Earth flashed above and vanished again. Laser gates moved in vertical rows, rising and falling across their path like hardlight guillotines. Each gate carried a bright orange node at its base, but some were tucked behind moving armor plates, forcing shots at bad angles.
John threaded the first two gates without firing.
The third moved too quickly.
Lauren destroyed the node.
The gate collapsed.
The fourth and fifth came together, one rising, one falling.
John rolled the fighter on its side and passed between them.
Lauren felt the left wing shield kiss the edge of the upper gate. It flared bright enough to flood the cockpit. The Broadsword bucked. John corrected.
Cortana’s voice snapped, “Please do not do that again.”
John said, “Route was clear.”
“The route was suicidal.”
“Clear.”
Lauren fired on the sixth gate node. “You’re both right.”
“I dislike that,” Cortana said.
The sixth gate died.
The Broadsword shot through into a wider tunnel filled with defense craft and turret nests. Lauren’s board lit red.
She exhaled.
Then started killing.
Cannons for drones. Missiles for turret nests. Rear fire for anything that tried to fold behind them. John lined the fighter up for every shot without needing to be asked. Once, a Forerunner interceptor crossed beneath them and she had no angle. John inverted the fighter for half a second, giving her the target against the upper wall. She killed it, and he rolled them back before the next laser gate cut the space they had occupied.
Cortana’s comm window flickered.
A voice came through, broken at first, then clearer.
“Chief? Chief, do you read?”
Lauren’s head lifted.
John’s answer came immediately. “Lasky.”
The channel stabilized. Thomas Lasky’s voice carried the strain of command under fire, older now than it had been even a few hours before. “Chief, the battlegroup’s moving forward to engage, but at the rate the Didact’s ship is advancing, he’ll reach the wire in T-minus two minutes.”
John flew under a particle beam and let Lauren clear the node beyond it.
“Commander,” he said, “direct all your ships to the Composer.”
“Copy that, Chief.”
A second voice entered behind Lasky, muted but urgent. “Sir, Infinity has firing solution, but the shields are holding.”
Lasky came back. “We can’t punch through unless you clear us a line.”
Cortana’s avatar flickered on the center display. “He’s sealed off the direct approach. We need to take out the particle cannons around the aperture.”
A new area opened ahead.
The trench spilled into a circular space carved into Mantle’s Approach’s hull, a vast armored basin surrounded by four massive particle cannons. At the center, a tunnel led deeper toward the Composer’s main weapon assembly, but as the Broadsword approached, plates began to close over it. The entrance sealed layer by layer, Forerunner armor folding shut over their only direct route.
Lauren stared at it. “He’s closing the door.”
John keyed the comm. “Infinity, the Didact just closed off our entrance to the Composer.”
Lasky answered fast. “We could try punching a hole in that hull plating, but Infinity won’t be able to get a clear shot with all that flak.”
John banked around the basin as the first particle cannon locked onto them. “We’ll take care of the guns.”
Cortana marked the four cannons. “Each cannon has a central energy source. Destroy the beacon at the middle of the weapon, then hit the exposed core.”
Lauren switched to missile priority. “First cannon.”
John drove toward it.
The cannon woke like an eye opening.
Its outer ring spun, gathering light. Turret nests around it came alive, hardlight beams and anti-air bursts filling the approach. Lauren took the smaller turrets first, firing in short bursts to clear a path. John kept the Broadsword low enough that the particle cannon’s main beam fired over them and struck the far side of the basin in a white flare.
Cortana shouted, “Beacon exposed!”
Lauren fired missiles.
The beacon cracked but did not die.
“Again,” John said.
“Reloading.”
The cannon started to charge a second shot.
John flew directly toward it.
Lauren got missile lock at the last moment and fired.
The beacon detonated.
The cannon’s outer shielding collapsed.
Lauren switched to cannons and poured fire into the exposed energy source. The core buckled, surged, and exploded inward. The particle cannon died in a storm of orange-white fragments that scattered across the basin.
Lasky’s voice cut through. “Whatever you’re doing’s working! Clear up the approach and Infinity could drop in to punch a hole for you.”
“One down,” Cortana said. “Three to go.”
John already had them moving toward the second.
The basin became a whirl of geometry and fire.
Covenant escort craft tried to follow them inside Mantle’s Approach’s shield envelope and died for the attempt, either to Infinity’s distant fire or the Didact’s own defense systems that did not care about ally-shaped inconveniences. Forerunner interceptors poured from vents near the remaining cannons. Laser grids flickered across sections of the basin floor. The Broadsword’s damaged wing dragged against shield turbulence every time John pushed too close to the hull.
Lauren killed the second cannon’s turret nests faster.
Not because it was easier.
Because she understood the rhythm now.
Turret cluster. Beacon. Shield flare. Core.
She fired missiles into the beacon, cannons into the core, and watched the second particle cannon fold in on itself.
“Two cannons neutralized,” Cortana said. “Two to go.”
Static crawled under her voice.
Not Composer residue this time.
Rampancy.
John heard it.
Lauren heard it.
No one had time.
The third cannon was protected by moving armor ribs that rose from the basin floor like black fins, blocking shots and forcing John into a corkscrew approach. The Broadsword’s left wing screamed on every turn. Lauren’s targeting solution kept slipping behind the ribs. Cortana forced predictive markers into place, overcorrected, and briefly gave Lauren a target that was not there.
Lauren did not fire.
Cortana caught it half a second later.
“False marker. Sorry.”
“Corrected,” Lauren said.
The real beacon exposed itself as the ribs rotated.
Lauren fired.
The missiles struck dead center.
The shield collapsed.
The core flared.
John held the ship steady through a hail of turret fire. Lauren destroyed the core.
The third cannon died.
“Only one gun left,” Cortana said.
Lasky’s voice followed instantly, bleeding through the same channel. “Copy, Cortana. Weapons, prepare firing solution. We promised to get John inside that ship, and I am not about to let that man down.”
For one second, the cockpit changed.
Not safer.
Warmer in a way that had nothing to do with heat and everything to do with someone outside the ship choosing to stand with them.
Lauren looked at the comm display. “Good man.”
John did not answer.
He did not need to.
The fourth cannon began charging before they lined up.
This one had learned from the previous three, or the Didact had adjusted the defense system manually. Shield plates locked tighter around the beacon. Interceptors swarmed the approach. Turrets focused fire not on the Broadsword’s nose, but on its wings and engines, trying to cripple instead of kill.
Cortana’s voice went razor-thin. “He’s adapting.”
John dove beneath a swarm of interceptors. Lauren fired upward and destroyed two before they crossed behind. A third clipped the Broadsword’s rear shield and burst against it, throwing the fighter sideways. John corrected before they hit the basin wall.
Lauren’s display flashed.
ENGINE TWO FLUCTUATION.
“Engine two is getting worse,” she said.
“I know,” John answered.
Of course he did.
They cut across the cannon’s underside, too low for the main beam, too close for comfort. The beacon was shielded behind two moving plates. Lauren waited. The plates opened for less than a second.
She fired.
One missile hit.
The other struck the closing plate and detonated harmlessly.
Beacon damaged, not destroyed.
The particle cannon began to turn toward them.
Cortana’s markers flickered. “You’ll need another pass.”
John did not pull away.
He rolled the Broadsword under the cannon housing and climbed along its side, flying so close that the fighter’s shields scraped against the weapon’s outer shell. Lauren’s reticle aligned with the beacon from below.
It was a terrible angle.
It was the only one.
She fired cannons instead of missiles, holding the trigger until the barrel heat warning screamed.
The beacon ruptured.
John pulled hard away as the cannon’s shield collapsed.
Lauren’s cannon overheated.
Missiles reloaded one heartbeat later.
She fired the entire rack into the exposed core.
The fourth particle cannon exploded.
The blast caught the Broadsword from behind and threw it across the basin. John fought the controls, engine warnings screaming, shield readouts collapsing and rebuilding in ugly strips. Lauren’s station went dark for two seconds, then rebooted with half the weapon systems offline.
“That’s the last one,” John said. “Infinity, you’re clear.”
Lasky’s reply came back steady and immediate. “Roger that, Chief. You might want to back up a little. Main battery, fire.”
John banked away from the sealed Composer entrance.
Space beyond the shield lit.
Infinity moved into firing position outside Mantle’s Approach, impossibly smaller than the Didact’s ship and still somehow the most beautiful thing Lauren had seen all day because it was human and angry and alive. Its forward batteries charged, blue-white light gathering along the bow.
Then Infinity fired.
The twin shots struck the hull plating over the Composer aperture.
For one violent instant, Mantle’s Approach absorbed the impact.
Then the armor gave.
A molten hole punched inward through the Forerunner plating, a burning tunnel carved into the sealed entrance. Debris blasted outward. Hardlight shields flickered, failed, and left a jagged opening into the ship’s interior.
Lauren stared through the canopy.
“Clean hit.”
John repeated it over comm. “Clean hit. We’re proceeding to insertion.”
Lasky answered, quieter now. “Acknowledged. We’ll be on station if you need us. Make sure you give the Didact our regards. Infinity out.”
Cortana brought up the new route.
The opening was already starting to close.
Forerunner armor plates moved around it, trying to heal the wound Infinity had made. The edges glowed molten, hot enough to make the Broadsword’s sensors scream before they even approached.
John pushed the throttle forward.
Lauren checked weapons.
Half offline. Enough dead that it mattered. Enough alive that it still counted.
“Go,” she said.
The Broadsword dove into the hole.
For a moment, everything became fire-colored. The fighter passed through molten hull plating, shields flaring under heat and debris. Then the light vanished, and they were inside Mantle’s Approach’s deeper structure.
Darkness swallowed the canopy.
The tunnel beyond the breach was narrow.
Too narrow.
Cortana’s voice sharpened. “Chief, look out!”
A wall moved across the passage ahead.
John rolled the Broadsword, and the wall scraped past beneath them, close enough to tear sparks from the already damaged wing. Another wall slammed down from above. Then another from the side. The ship was closing the wound around them from the inside, folding its own architecture into their path.
Lauren’s station flashed proximity warnings faster than she could read them.
John threaded the first moving wall.
Then the second.
The tunnel narrowed ahead.
Cortana’s avatar flickered across the cockpit display, red at the edges, blue in the center. “I don’t think this is going to end well.”
John said nothing.
Lauren looked past his shoulder at the closing tunnel.
The Broadsword’s damaged engine coughed.
The left wing struck the wall.
The fighter spun.
John fought the controls.
The Broadsword slammed sideways into the tunnel, shields collapsing in a white-blue burst. Metal tore. The cockpit jolted hard enough to black Lauren’s vision for half a second. The fighter bounced off the wall, struck something below, and skidded along a Forerunner deck in a shriek of wreckage and sparks.
The canopy cracked.
The weapons console died.
The whole world became impact, metal, and the sound of the Broadsword stopping by destroying everything beneath it.
Then silence.
Not true silence.
The kind after a crash, full of cooling metal, hissing hydraulics, failed alarms, and the distant pulse of a machine that had not been inconvenienced enough to stop.
John moved first.
Lauren’s eyes opened behind the visor.
Her restraints had locked. Her armor reported bruising she did not care about, shield collapse, recharging, no breach. The cockpit around her was half-dark, half-lit by red emergency strips and the orange glow beyond the cracked canopy.
John turned his helmet slightly. “Lauren.”
“Here.”
“Can you move?”
“Yes.”
Cortana’s voice came from the cockpit speakers, thin and annoyed with survival itself. “Now what do we do?”
John unlatched.
The canopy was jammed.
He shoved it upward with both hands. It resisted, then tore free and clanged onto the Forerunner deck outside. Air rushed in, metallic and cold. John climbed out first onto the ruined nose of the Broadsword.
Lauren released her harness and followed through the shattered cockpit frame. Her boots hit the deck beside him.
The Broadsword was done.
Its wings were shredded, one engine torn open, nose crushed against a Forerunner support strut. The HAVOK delivery casing underneath had survived, locked in its armored cradle beneath the fighter’s central body.
John dropped to the lower hull.
Lauren moved with him.
Together they forced the damaged casing open.
The HAVOK warhead sat inside, intact.
Cortana transferred back into John’s armor in a soft, broken flicker. “The fighter is not going anywhere.”
John released the warhead from the missile housing.
The nuke dropped into its portable frame with a heavy metallic clunk.
He locked the frame onto his back.
Lauren picked up her rifle from the wreckage, checked the magazine, then looked toward the tunnel ahead.
Promethean signatures moved in the dark.
John grabbed his assault rifle.
“Plan B,” he said.
Lauren stepped beside him.
Cortana opened the route deeper into the ship.
And behind them, the Broadsword cooled in pieces, its work done, its last flight carved into the belly of Mantle’s Approach.
