The trench smelled like shit and blood, but Carlos didn't care. He'd been in it for three days and his nose had given up somewhere around day two. Plasma bolts cracked overhead like ugly green lightning, and every time one hit the parapet it showered them with dirt and hot rock.
"Suppressive fire, SUPPRESSIVE FIRE," somebody screamed down the line. Carlos couldn't see who. He just poked his rifle over the top and squeezed the trigger until the magazine clicked empty. The Kuthara were out there, moving in the smoke like a tide of knives. He'd seen them up close once. Never again if he could help it.
Jen was next to him, face streaked with grime, teeth bared. She wasn't screaming. She was just shooting, calm like she was at a range. Carlos always thought that was the scariest thing about her. When she got quiet, shit was about to get bad.
Mike tumbled into the trench from the left side, nearly landing on Carlos's legs. "They're on the flank," he gasped. "They're fucking on the flank, we gotta go now now now."
"Go where?" Carlos shouted.
"I dunno, the LT said something about a rally point. Gamma Four. Gamma Seven. I can't remember, my ears are ringing."
"Gamma Seven," Jen said without looking at him. "It's a comms station about two klicks back. Old pre war bunker. Sam's already there, I heard on the squad channel."
"Two klicks," Carlos said. He looked at the open ground behind their position and his stomach did a slow roll. Two klicks of dirt and craters and no cover. Kuthara drones would pick them off like targets in a shooting gallery. "That's a lot of open ground."
"Yeah well the alternative is we stay here and die," Mike said. "So I'm gonna start running."
Jen slapped Carlos on the helmet. "On your feet. Let's move."
They went. The three of them scrambled out of the trench and pelted across the broken earth. Carlos's legs pumped and his lungs burned and his brain shut off everything except the sound of his own breathing and the thud of his boots. Somewhere behind them the world was ending but he didn't look back.
Plasma bolts stitched the dirt around them. Mike yelped and stumbled, clutched his arm. "I'm hit, I'm hit!"
"Walk it off," Jen barked. "It's a graze, you're fine, keep moving."
Mike swore at her, a long creative string of words that included some stuff about her mother, but he kept moving. Carlos almost laughed. Almost. The adrenaline was doing weird things to his brain.
They made it to a low ridge and threw themselves behind a burned out troop carrier. Carlos risked a look back. The trench line was a smoking scar in the ground. Kuthara walkers, big spindly things like praying mantises made of black glass, were stepping over the defenses like they were nothing. The bugs moved in waves behind them, chittering and clicking, too many to count. It looked like a bad dream.
"Fuck me," Mike breathed. "They're everywhere."
"Don't watch," Jen said. "Run."
They ran again. The ground sloped down toward a cluster of prefab buildings that had been a colonial settlement once, before the bugs came. Now it was just rubble and shattered concrete and a few walls still standing, leaning like drunks. The relay station was supposed to be past that, dug into a hillside. Carlos could see it, a low gray hump with a single blinking light.
They crossed the settlement in a dead sprint, weaving through wreckage. A Kuthara scout drone buzzed past, its sensor eye flickering. Carlos dove under a collapsed roof and held his breath. The drone hovered, turned, zipped away. Probably had bigger targets.
"Close," Mike whispered.
"Yeah," Carlos said. "Real close."
They reached the hillside. The relay station door was a heavy blast hatch set into the rock, and it was cracked open just enough for a body to squeeze through. Light spilled out. Somebody was inside.
Sam's voice came from the gap. "Get in get in get in, hurry up."
They squeezed through one by one. Jen last. The moment she was inside Sam spun a manual wheel and the hatch groaned shut, sealing with a thud that Carlos felt in his chest.
The interior was a single circular room, maybe twenty meters across. Consoles lined the walls, most of them dark, a few blinking with status lights. Sam was there, looking like he hadn't slept in a week. His uniform was rumpled and he had a bandage wrapped around his left hand. He was sitting at the main console with a half eaten ration bar in one fist.
"Oh thank god," Sam said. "I was starting to think I was the only one left in this sector."
"What's the situation?" Jen dropped her pack and immediately started checking her rifle, her hands moving on autopilot. "Command's been feeding us garbage all day. They said something about a counter offensive but that was twelve hours ago and I haven't heard jack since."
Sam finished his ration bar and wiped his mouth on his sleeve. "Yeah, well. There is no counter offensive. That was a lie."
Mike froze. "What do you mean a lie?"
"Sit down," Sam said. "All of you. I got a recorded message from Fleet. I been sitting on it for a couple hours, waiting for someone to show up. You're gonna want to hear it."
Carlos felt something cold settle in his gut. He didn't sit. He leaned against a console and crossed his arms. "Just play it."
Sam tapped a key. A holographic face flickered into the air above the console. Fleet Admiral, no name, just a rank and a face that looked like it had been carved out of old leather. The Admiral's voice was flat, no emotion, like he was reading a grocery list.
*"Soldiers of Gamma Seven Relay. What I am about to tell you is classified beyond all clearance levels. You are receiving this message because you have been designated as the final activation authority for Operation Emberfall. Over the last three standard years, High Command has seeded every major planetary body in this system with deep crust planet cracker warheads. The Kuthara main fleet, responding exactly as our strategic models predicted, has now assembled in orbit around those worlds. They believe they have won a decisive victory. Gamma Seven is the only remaining trigger station with a direct hard line connection to all warheads. Remote detonation is impossible due to Kuthara jamming. You are to detonate the warheads at the moment of maximum enemy fleet concentration. Once initiated, the chain reaction will annihilate the fleet and render the system uninhabitable for the next several thousand years. There is no extraction. There is no escape. Thank you for your sacrifice. Terra remembers. Morven."*
The message clicked off.
Nobody moved.
Carlos stared at the dead holo emitter. The cold feeling in his gut spread up into his chest and down into his legs. He felt like he was floating a little. His head was still ringing from the run and now this thing was sitting in his brain like a chunk of ice.
Mike broke first. "What the fuck," he said, and it wasn't a question. It was just a sound, pushed out of him like a punch. "What the actual fuck."
Jen was very still. She had stopped checking her rifle and her hands were just resting on it, not moving. "They left us here on purpose," she said. Her voice was quiet and flat, almost like the Admiral's. "They let the bugs overrun the whole sector. They let us fight and die and hold the line, and the whole time they knew it was a trap. And we were the bait."
"That's about the size of it," Sam said. "The whole retreat was a feint. All those transports leaving, the civilians getting evacuated for that fake plague outbreak eight months ago. They cleared the worlds first. Then they let the bugs walk right in."
"I remember the plague outbreak," Mike said. He was pacing now, two steps back and forth, his wounded arm hanging limp. "My sister was on the evacuation list. I thought she was dead. You're telling me she's alive?"
"Far as I know," Sam said. "High Command shipped millions of people out on transport convoys, told everyone it was quarantine. Nobody asked questions because nobody wants to ask questions during a war. You just do what you're told."
Carlos finally found his voice. It came out rougher than he expected. "So all of this. The trenches. The dead squads. The bugs chewing through the colony. It was all just theater."
Sam nodded slowly. "Theater to keep the Kuthara focused. The bugs don't understand deception. They don't lie. They don't bluff. They see a defense, they think it's real. They see a retreat, they think they're winning. So we gave them exactly what they expected. A desperate last stand. A broken human line. And the whole time, they were walking onto a bomb."
Jen set her rifle down carefully, like it was made of glass. "How long do we have?"
Sam pointed at a countdown on the main display. It read 11:42 and ticking. "The Kuthara mind that controls the fleet, it's called Aramathku. It's not stupid. It's spreading its ships out to claim all the real estate, taking its time. We wait until the concentration is optimal. Then we light the fuse."
"And after that?"
"After that, twelve worlds crack open and the whole system turns into a fireball. Us included."
Mike stopped pacing. He looked at the countdown, then at the door, then at his own hands. "So I'm never gonna see my sister again."
"No," Sam said quietly. "But she's gonna live. That's something."
"That's something," Mike repeated. He didn't sound convinced.
Carlos pushed himself off the console and walked over to the door. He put his hand flat against the cold metal. Outside, he could hear the faint thumping of artillery and the high thin screeching of the Kuthara. They were landing troops. They'd be here soon.
"You know," he said, "I woke up this morning and I was so hungry I could eat a horse. I had this protein bar that tasted like sawdust. I was bitching about it to myself. And now I'm never gonna eat anything again."
Jen snorted. It might have been a laugh. "You're an idiot, Carlos."
"I know." He turned around. "But I'm an idiot who's about to win a war. So there's that."
Mike shook his head, but something cracked in his expression. A tiny smile, bitter and sharp. "You always gotta find the bright side, don't you."
"Somebody has to."
The station trembled. A closer impact this time, maybe within half a klick. The consoles flickered and stabilized.
Sam checked the countdown. "Nine minutes. The Kuthara have landed a swarm around the entrance. They'll breach the door in maybe six or seven."
Jen stood up and walked over to a weapons locker in the corner. She pulled out a heavy rifle, the kind with a thick barrel and a magazine the size of her forearm. She hefted it like it weighed nothing. "Then we hold them off for six or seven. Buy Sam time to do whatever he needs to do."
"The sequence is mostly automated," Sam said. "I just need to input the final command at T-zero."
"Great. So we just gotta not die for nine minutes."
Carlos joined her at the locker and grabbed a second heavy rifle. "I always wanted to go out in a blaze of glory. Feels cliche, but what the hell."
Mike picked up a rifle too, his movements slow and deliberate. "My sister's name is Elena. She's fourteen. She likes drawing pictures of starships and she's terrible at math." He chambered a round. "I want you guys to know that. In case there's some kind of record somewhere."
"We'll remember," Jen said. "Elena. Starships. Bad at math."
Carlos nodded. "Got it."
The next few minutes passed in a strange, stretched kind of silence. They took positions behind whatever cover they could find, consoles and crates and a tipped over maintenance droid. Sam stayed at the main console, fingers moving over the keys, muttering to himself about signal relays and optimal timing. The countdown ticked.
Outside, the screeching grew louder. The Kuthara were at the door. Carlos could hear their claws scraping on the metal, could feel the vibration through the floor.
Three minutes on the clock.
The door sparked. A thin line of green light traced across the seam, cutting through the blast hatch. The metal began to glow.
"They're plasma torching the door," Mike said. "That's gonna go faster than we thought."
"Then we shoot the first thing that comes through," Jen said. "Simple."
The door buckled inward with a scream of twisting metal. A gap appeared, wide enough for a Kuthara warrior to jam its head through. It was a nightmare thing, all chitin and mandibles and too many eyes. It let out that screech, the one Carlos had heard in his dreams for weeks.
Jen fired. The heavy rifle kicked and the bug's head vaporized in a burst of blue light. The body slumped and clogged the gap for a precious few seconds.
"Good shot," Carlos said.
"I know."
More bugs pushed through, climbing over the dead one, tearing at the edges of the door to make the hole wider. Mike fired burst after burst. Carlos joined him. The air filled with the shriek of dying Kuthara and the ozone stink of plasma discharge and the overlapping thunder of gunfire.
One minute on the clock.
Sam shouted over the noise, "I'm arming the sequence. When it hits zero, I press the button."
"Do it," Carlos yelled back. He didn't look. He was too busy shooting.
The Kuthara were pouring through now, a flood of armored bodies. One lunged at Jen and she smashed it in the face with the butt of her rifle before putting a round through its thorax. Mike was laughing, a wild unhinged sound, spraying fire into the mass.
Thirty seconds.
Carlos's rifle clicked empty. He dropped it and pulled his sidearm, a dinky little pistol that felt like a toy. He shot a bug in the mouth and it kept coming. He shot it again and it stumbled. The third shot killed it.
Fifteen seconds.
The room was a chaos of screeching and gunfire and the red glow of emergency lights. Sam was standing at the console now, his hand hovering over a single large key. He looked back at them, and for a second his face was just tired, just human, just done.
"We did our job," he said.
Ten seconds.
Carlos ran out of ammo again. He threw the pistol at a bug. It bounced off its head. He laughed and the laugh felt good and insane and free.
Five seconds.
Jen grabbed his arm and pulled him back behind a console. She was bleeding from a cut on her forehead and her eyes were blazing. "We're all here," she said. "Right here."
Four.
Mike stopped shooting and just stood up. "Elena," he said. "You better draw a lot of starships."
Three.
Sam pressed the button.
Two.
The Kuthara screamed.
One.
Carlos closed his eyes.
Zero.
The signal traveled along buried cables, ancient infrastructure that the colonists had laid down decades ago and then forgotten about. It shot through relay nodes hidden in sewer systems and power grids and old mining tunnels. It reached receivers bolted to the cores of twelve planets, twelve worlds that had once been human homes.
The warheads woke up.
On the bridge of the Kuthara hive mind, Aramathku perceived a sudden spike of energy from the relay station. It was a minor anomaly, a flicker of coherent signal in the middle of static. The Mind dismissed it at first. Humans were desperate creatures, always sending out distress calls and final messages. This would be no different.
Then the data cascaded. The warheads were not just conventional explosives. They were deep crust crackers, devices designed to split continental plates. And there were thousands of them. On every world. Beneath every landing zone. Under every captured city.
Aramathku tried to pull its fleet away, tried to scatter, tried to jam the signal, tried to do anything. But the signal was already moving at lightspeed through hardlines that could not be jammed, and the warheads were already firing, and the planets were already breaking apart.
The Mind had one final moment of clarity. It understood, then, the shape of the trap. The humans had not been defending these worlds. They had been inviting the swarm to stand on them. They had sacrificed their own nests. They had spent millions of their own lives like bullets from a gun. The thought was so alien, so utterly monstrous, that the Mind could not process it. There was no equivalent in the Kuthara consciousness. They did not burn their own homes. They did not use their own soldiers as bait.
The first planet cracked. The second. The chain reaction swept through the fleet at the speed of light, and the Mind of Aramathku, along with every ship and every warrior and every drone, ceased to exist.
In the relay station, Carlos felt nothing. One moment there was noise and heat and the stench of battle. The next moment there was light, bright and clean and total, and then there was nothing at all.
On the bridge of the fleet carrier Resolute, half a light year from the detonation zone, the Admiral stood at his tactical display and watched twelve star systems go supernova. The screen was a wash of white and violet and harsh ultraviolet. The computer struggled to render the scale of the destruction.
The ops officer next to him spoke in a voice that cracked slightly. "Sir. The entire Kuthara main fleet signature is gone. We're reading total annihilation. The Aramathku mind presence has flatlined. No survivors."
The Admiral nodded. "And our own losses?"
"All bait colonies, all stationed personnel. The ground forces left behind. The relay team at Gamma Seven." The officer swallowed. "Confirmed KIA."
"Get me a count. Then send a burst message to Terra."
"What should the message say, sir?"
The Admiral turned away from the screen, which was still burning with the funeral pyre of a hundred billion enemies and a few million humans. His face was unreadable.
"It's done," he said.
The officer hesitated. "Sir. The people we left behind. The relay team. They did it. They held out and they pushed the button."
"I know."
"Should we put them in for commendation? I can start the paperwork for posthumous honors."
The Admiral walked to the door of the bridge and paused with his hand on the frame. He didn't look back.
"Put them in for whatever makes you feel better. They're dead. They don't care about medals."
He left.
The ops officer stood alone for a moment, staring at the empty doorway. Then he looked back at the display, at the roiling clouds of plasma and debris that had once been twelve worlds and a billion nightmares. He thought about a relay station buried in a hillside, and a handful of soldiers who had sealed their own death warrant without hesitation.
He started the paperwork anyway.
Somewhere, across the vast dark between stars, a fourteen year old girl named Elena sat in a cramped transport cabin and drew a starship on a scrap of ration packaging. She didn't know why she was crying. She just felt, for a moment, a strange warm pressure in her chest, like someone had said her name from very far away.
She finished the drawing. The starship had three engines and a lot of windows and a name scrawled on the side in shaky letters.
She named it The Promise.
And the transport carried her onward, into the dark, away from the burning graves of twelve worlds that humanity had given up without a second thought, because that was how you won a war.
