Sarah Burks spread the medical files across the command office table and made her case before anyone could talk her out of it. She was a Reilly's Ranger, sent to Calico Flats to build a trade post and, if the rumors held, a medical facility stocked from Vault 141. The rumors named a prize: a G.E.C.K. buried inside. She tapped the top folder. "If it's real, we can turn this whole valley into something that lasts. But I need to know what else is down there first." Zelda Verada stood across from her, medic's bag still on her waist belt, red beret pushed back. She had already spent every favor she owned securing a field hospital near the vault. She read the files the way she read a wound. "You're not asking me if I want a G.E.C.K.," she said flatly. "You're asking me what it might cost. Say it plain." "Sublevel three," Sarah said. "The construction manifests list experimental biological preservation. That's not first aid. That's the kind of research that goes wrong quietly." Zelda didn't flinch. "I've patched people the wasteland tried to erase. I know what wrong looks like." She set the folder down. "If there's a machine down there that grows clean water and soil, I want it. But I won't build a hospital on top of something that eats the people it's meant to save. Prove which one it is." The door opened. Sinclair Feldman came in shaking dust from his radio backpack, a recon officer from Red Hills Traders who mapped ruins for a living. He and his team were allied with the Rangers on this vault. He'd been quiet since arriving, but now he pulled a folded sheaf of his own from his jacket. "Heard my name and the word cost," he said. "Both usually find me." He dropped his pages beside Sarah's files. "Vault 141 intel. I've been sitting on it because I wasn't sure this alliance would hold. It's holding. So here." Sarah scanned his notes fast. Decrypted door logs. A camp layout drawn in his careful cartographer's hand. "Someone breached the door before we got here," she said. "An unknown party. Set up inside." Sinclair's voice went short and hard. "They knew what they wanted. My decrypts point them at the medical labs. Same floor your manifest calls preservation." Zelda looked between the two stacks of paper. "So we're not the only ones who read the rumor." "No," Sinclair said. "And a G.E.C.K.'s a lousy thing to fight over in the dark." Sarah pulled the G.E.C.K. manual from her pouch and laid it on top, faded blue and yellow, her own notes crowding the margins. The three intel sources now agreed on one floor and one danger. "Then we don't wait a week," she said. "We go for sublevel three. Before they clear it out." Zelda snapped her bag shut. "I'll ready the hospital." The plan was set. Someone was already inside, and now it was a race.

The race was on, but Sarah refused to walk in blind. Before anyone touched the vault door, she needed to know who was already inside. She took Corporal Desior, a grey tabby breach specialist Brad had pulled off another job for this mission. They climbed to a hill above the ruined Vault-Tec garage. Its double doors hung wrecked, punched through with jagged holes. Sarah crouched low and studied the wound in the metal. Desior was quiet and precise. He raised his night vision monocular and swept the entrance. "Movement," he whispered. "Four, maybe five. Armed." He passed her the scope. Sarah looked. The figures below wore mismatched armor, spiked and scavenged. One dragged a crate toward the doors. "Raiders," Desior said. "Not a research crew. They came to strip it." Sarah's stomach tightened. Raiders in the vault meant the G.E.C.K. wasn't just a race anymore. It was a fight. She unpacked the long-range thermal camera and set it on its tripod. The lens hummed and locked onto the doorway. Heat blooms marked each body in orange. She started recording, counting, mapping their patrol. "Five confirmed," she murmured. "Two stay at the door. Three go in and out." She logged the timing between trips. Data was her weapon. If she knew their pattern, the team could time a breach. Then she pulled her radio, the compact shortwave unit with its worn dial, and keyed the frequency for the garage base. "Sinclair, come back." Static, then Zelda's flat voice answered instead. "Sinclair's on the roof antenna. What did you find?" Sarah remembered Zelda's warning from the command office. Zelda had spent every favor she owned on the field hospital. She had no cushion left if this went wrong. Sarah chose her words with care. "Not researchers. Raiders. Five of them, working the entrance." The radio went silent a beat. "Raiders don't decrypt door logs," Zelda said. "Someone hired them, or someone let them in. Either way they'll gut the medical labs for scrap and sell what they don't understand." "I've got them on thermal," Sarah said. "I can build their patrol pattern. Send the backup team. We hit them on a gap." "Funny what survives when no one knows what they're looking at," Zelda said. "They could smash the G.E.C.K. thinking it's junk." A pause. "Backup's coming. Sergeant's group is closest. Hold your hill and keep filming. Don't let them see that lens shine." Desior tapped Sarah's shoulder. Below, one raider stopped and stared up the slope. Sarah killed the camera's glow and pressed flat. The raider watched, then turned back inside. "Close," Desior breathed. Sarah exhaled. She had her answer, and it was worse than a rival crew. The vault held a machine that could heal the valley, and the people inside would tear it apart for parts. The survey was done. Now she had to beat them to sublevel three.

The raiders were gone. Sergeant's team had hit them clean during a patrol gap, and now the ruined garage belonged to Sarah's crew. She stepped through the broken doors and swept her light across the scarred metal. The place still smelled of raider camp. But it was theirs now, and that meant she could finally search for the way down to the medical labs. A sealed door blocked one wall. Logan crouched at its panel, the Atomic Cats tech who read machines by what was broken in them. He had guided the Rangers scouts through these ruins for weeks, quiet unless the work earned words. He pried a cover loose and studied the wires. "Lock's mechanical," he said. "Raiders never cracked it. Lucky them." His two-fingered hand worked a tool into the seam. Metal groaned. The door slid back. Sarah expected a hallway to sublevel three. Instead her light found shelves. Rows of sealed food, stacked crates, and a tall glass cabinet against the far wall. Not the labs. A storeroom. She stared at the crates of sealed rations, more food than the whole team had rationed in a month. Then her light hit the cabinet. Behind the glass sat small metal containers on every shelf, each labeled in faded print. She stepped closer and read one. Preserved tissue samples. Her stomach tightened. She keyed her radio. "Zelda, come back. We cleared the raiders and opened a side room." "Say what you found," Zelda answered. Flat, direct, the way she said everything. "Food storage. Sealed rations, crates of them. Enough to feed the guard station a long time." Sarah paused at the cabinet. "And a preservation unit. Tissue samples behind glass. Prewar." The radio went quiet a beat. When Zelda spoke, her sentences stretched, the way they did when medical tech was on the line. "Rations keep my staff fed without spending favors I don't have. That's real. The samples matter more. If the cooling still holds, that's viable prewar biology. My hospital could use it, if it's clean." A shorter beat. "Is the seal intact?" Sarah leaned to the cabinet's edge. A thin frost lined the door. But one hinge hung wrong, cracked by the same blast that had scarred the garage. Cold air leaked from the gap. "Seal's broken," she said. "Cooling's failing. If those samples are worth anything, they won't be for long." "Then they're not stored. They're dying," Zelda said. "Get Mary to me. Now." Sarah looked at the crates and the failing glass. The food was a clear win. The samples were a clock already running. She had wanted the labs below. Instead she'd found a prize that would rot before she reached them. She keyed the radio again and called for the tech to bring the medic. The way down would have to wait. Something up here was already slipping away.

The samples were saved. Mary, the trained tech who worked Zelda's field hospital, had raced up with cold packs and sealed the dying tissue into a hard case. Now she stood beside Sarah in the ruined garage, clutching her folder of medical files. The storeroom was clear. But Sarah still needed the way down to sublevel three, where the medical labs and the G.E.C.K. waited. She swept her light past the dead ghoul at the door, the one the guard officer had shot when the vault opened. "Weapons ready," Sarah said. Logan moved up first. The Atomic Cats tech had guided the Rangers scouts through these ruins for weeks, reading broken machines like other people read faces. He crouched at the far wall and studied a stairwell mouth choked with rubble. "Right entrance to the lower level's collapsed," Logan said. He pointed at a beam bent flat across the stairs. "That's not raider work. Old blast brought it down. We're not digging through that today." He said it plain, the way he said everything, no wasted breath. Sarah's stomach sank. One route to the labs, gone. She turned, searching the dark for another door. A panel on the opposite wall clicked. Something behind it stirred. A rounded white shell rolled out on stiff limbs, a red cross painted on its chest, one arm ending in a needle. A medical robot, dormant for centuries, now waking. Its instrument arm swung toward Mary. Sarah stepped between them and raised her pistol. "Doctor," the robot said. Its voice crackled. It stopped, waiting. Mary froze. The needle hung inches from her folder. Sarah's finger tightened on the trigger. If she fired, the shot might bring more ferals from the vault. If she waited, the machine might inject Mary with whatever it held. Sarah lowered her gun a hair. "I'm a doctor," she said. The robot's lens flickered blue. "Present identification." Sarah reached into her jacket pouch, past the tech tools, and drew the card she had carried since the bunker archives. A prewar physician ID. Her own name, printed on institutional white. She held it flat to the lens. A thin light scanned the barcode. Seconds stretched. Mary didn't breathe. "Dr. Sarah Burks. Access approved," the robot said. The needle arm folded back. "Standing by for medical orders." Mary let out a shaking breath and stepped clear. Sarah kept the card up. Her mind was already racing. This machine had run these halls before the war. It knew the layout. It answered to a doctor's credentials. "Med-Serve," Sarah said, testing the word. "The right stair is blocked. Is there another route to sublevel three?" The robot rotated, lens fixed on her. "Affirmative. Alternate access exists. Doctor clearance required at the inner checkpoint." Sarah pocketed the ID. She had lost one road down and gained a guide who would only obey her. Now she had to follow a centuries-old machine deeper, on trust she couldn't verify.

The medical robot led them down a service shaft, past the collapsed stairs, to a rusted door marked MEDICAL 141 EXPERIMENTS. The panel above it flickered. Cracked glass framed the lab beyond. Sarah held her physician ID to a scanner, and the door ground open. Inside, computer stations still glowed. Records lay scattered across the floor. Zelda's tech, Mary Long, stepped in behind her, glasses catching the blue light, folder clutched to her chest. "Secure it," Sarah said. Logan and the scouts swept the corners. Nothing moved but dust. "Clear," Logan said. He pulled off his hat and studied a live terminal. "This one's still running. Somebody kept it warm." He crouched and read the screen, fingers hovering. "Preservation lockers, back wall. Some coolant lines held. Med supplies in there could still be good." Mary moved fast. She and Zelda's kit worked the lockers, checking seals, sorting vials into a hard case. "Stimpaks. Antibiotics. Blood expanders," Mary called, voice steady. "Most of it's usable." Zelda had spent every favor she owned to stock the field hospital. This lab would refill her shelves. Sarah watched the case fill and felt the trade post's future grow more solid. "Sarah." Logan hadn't looked up. "You need to see this log." His voice stayed flat, but he'd gone still. "System restart timestamps. Whole facility rebooted, over and over, right before the collapse. Something drove the power crazy." He tapped the screen. "Reactor readings spiked, then flatlined. That's what brought the stairs down. Not a raider blast. An accident." Sinclair Feldman came through the door then. The Red Hills recon man kept his rifle slung, but his yellow eyes swept the room like he priced every corner. He was the one who'd sealed the lower levels tight, the man who read danger before it read him. He knelt by an overturned desk and lifted a battered laptop. It still ran. "Found the whole story, gal," he said. He turned the screen toward her. A med-tech incident report. Exploded pressure valve. Radiation exposure. F.E.V. contamination. "Reactor leak set off a chain," Sinclair read. His voice dropped, short and hard. "Then the vault AI triggered the G.E.C.K. as an emergency fix. It went wrong. Mutated everything on levels five and six." Beside the laptop lay a worn notebook. Sarah picked it up. Cramped handwriting filled every page, growing shakier as it went. Fear in ink. The last lines named the fungi, the burns, the screaming below. "Whoever wrote this watched it happen," she said quietly. Sinclair closed the laptop. "Your G.E.C.K.'s down there. So's whatever it made." He nodded at a sealed door across the lab, its lock panel dark, marked LEVEL 4. "That's the only way deeper. And it's locked to level four clearance, not a doctor's card." Sarah stood among the salvaged supplies she'd won and the door she couldn't open. The lab was hers. The way down was not. She looked at the sealed panel and knew the next fight waited behind it.

The lab was theirs, but the door to Level 4 stayed dark. Sarah stood over the salvaged supplies and studied the dead lock panel. The G.E.C.K. waited past it. Her physician ID meant nothing to that clearance. She turned to the team. "We can't force it yet. Let's clean this place first. Every terminal, every record. Something in here tells us how to open that door." The scouts hauled broken chairs aside. Sarah pulled records off the floor and stacked them. In a fallen cabinet she found a blue and yellow data pad marked with Vault-Tec logos. Its screen still lit. Dense text scrolled under a warning triangle. She read a line, then another, and her tail went stiff. "This is the operations manual," she said. "For the G.E.C.K." Mary Long stepped close, folder held to her chest, glasses catching the blue light. She had joined Zelda's team as the field hospital tech, and she read fast. "Give me a minute." Her eyes moved down the screen. "It says the kit terraforms a whole area at once. Water, soil, power. And a warning. Never run it near a failing reactor." She looked up. "That's what killed this place." Logan crouched at a live terminal, hat pushed back, missing two fingers curled against the keys. He read machines by what wasn't there. "Got something," he said, flat. He held up a scuffed disc, cracked at one edge. "Accident footage. Levels five and six." He fed it to the terminal. The screen flickered to gray video. A pipe burst. Men in vault suits ran. One in a captain's uniform shouted an order, then keyed a wall panel. "That's the sealing procedure," Logan said. "He locked the lower levels from the inside. Before it spread." The room went quiet as they watched the captain die on screen. Then Sinclair Feldman came through the door. The Red Hills recon man kept his rifle slung and swept the room with his yellow eyes. He carried a weathered instrument, a repaired radiation analyzer, its needle already climbing. "You'll want this reading, gal," he said. He set the device on the desk. The needle jumped past level five, then level six. "That's coming up through the floor. From below four." He tapped the dial. "Whatever the G.E.C.K. mutated, it's still hot down there. You crack that door without suits, you cook." Sarah looked from the manual to the disc to the climbing needle. Three answers, one hard truth. "So we seal the lower levels tight," she said. "Same as the captain did. We hold this lab and stage from here." She met Sinclair's eyes. "Nobody goes past four until we have explorer suits and a way through that lock." Sinclair nodded. "Smart. Guilt won't dig you a grave, but radiation will." Logan pulled the disc and pocketed it. Mary logged the manual's warnings. They agreed, first they set level 3 lab, command station & supply room. Then plans can be made the explore level 4 and retrieve the used G.E.C.K. to find others.

The lab was sealed and stocked. Sarah left the vault at dawn to check the new field hospital herself. The G.E.C.K. still waited past Level 4, but suits and a breach plan would take time. For now she needed eyes on the road and a count of who could walk. She climbed into the patrol truck and keyed the radio. Brad's voice came through over the engine noise. He ran the campaign against the ghoul raiders from a weathered board of patrol orders and a ten-day timeline. "Road's clean as of last check," he said. "But heh, stay sharp. Scattered ghouls still work your route. Information's currency out here, and mine says they move at first light." Sarah thanked him and watched the ridgeline. The truck's roof radar swept the dust. Then six shapes rose from a culvert and rushed the road. Ghouls. They moved together, not wild, flanking both doors. One slammed the hood. Sarah fired through the window and hit two. The driver swung the wheel. A ghoul tore the side mirror off. She grabbed the radio and pressed hard. "Distress call. Six ghouls, patrol road, taking fire. Need backup now." Her voice stayed level, but her tail lashed the seat. "Copy. Three minutes." The reply was clipped and flat. Fredrick Carr. The former special forces soldier never wasted a word. Brad had summoned him to help build the trade center, and now he ran its security. "Hold the vehicle. Do not dismount." Three minutes felt like thirty. A ghoul clawed the door handle open. Sarah kicked it shut and shot through the gap. The driver bled from one arm. She pressed her hand over the wound and kept her pistol up. Then a second truck roared over the rise. Carr leaned from the window and fired his .45 in short bursts. One ghoul dropped. Then another. He stepped out, walked forward, and finished the last two on the ground without hurry. He holstered the pistol and looked at Sarah through the broken glass. "You're hit?" he asked. "The driver. Not me." She climbed out, legs shaking. "Then drive him in," Carr said. "They'll come again. These ones plan." At the base, Sarah worked the field hospital bench herself. She cleaned the driver's arm and closed it with a stimpak. Two scouts from Carr's escort had claw cuts. She stitched one and dosed the other for radiation. Her hands stayed steady now that the fight was done. Brad found her washing blood from her gloves. He studied his timeline board, then tapped a date. "Parks needs nine days to finish the pancake house job," he said. "Until then, no spare guns for your vault road. We hold what we've got." Sarah nodded. The lab was secure, the hospital running. But the road between them bled, and she had nine days to wait before real help came. She pinned the driver's chart to the board and started counting the days.

Nine days still hung over the vault road. Sarah couldn't just wait them out. Brad's team was striking St Alphonse's that night, far to the north. If the raiders there panicked, they might run supplies to their smaller base southwest of the ridge. Sarah took the armored transport and drove to the high ground above that forward base. Donovan rode in the gun seat, headphones on, radio backpack humming at his feet. She parked the armored truck behind a low rise and cut the engine. The mounted cannon sat quiet above them. Donovan tuned his set and leaned close to the speaker. He was the Rangers' communications man, and he read the air like a map. "Oh man, listen to that," he said. He tapped his watch. "2:21. That's artillery. Brad hit the pancake house right on time." The far booms rolled over the hills. Below, the forward base woke up. Sarah lifted her thermal scope and counted heat. Raiders ran between tents. Headlights flared. "They're loading," she said. "Three trucks." She pulled her field pad and wrote it down, time and count, her hand steady. "They're running the panic straight to us," Donovan said. His voice stayed flat, like reading a report. "Three cargo trucks, headed out the south track. Hell if they know we're sitting on it." Sarah keyed the radio to Captain Hills. He commanded the small crew Fredrick had hired for the trade center, an orange tabby in a green beret who never rushed. "Hills, this is Sarah. Three trucks leaving the southwest base, loaded, your direction. Cut the column." "Copy," Hills said. "Holding the track." The first truck crested the rise. Hills's crew opened up from the rocks. Sarah swung the armored transport's cannon onto the lead vehicle. The 20mm tore through its hood. The truck slewed and stopped. The second rammed it from behind. Donovan worked the gun and raked the third as it tried to reverse. It caught fire and spilled raiders into the dark. A ghoul in torn army fatigues climbed from the wreck, backpack strapped tight, moving with grim order instead of madness. It raised a rifle. Hills dropped it with one shot. The firing thinned. Then it stopped. "Column's down," Hills radioed. "No losses here." Donovan pulled his headphones off and grinned. "Three trucks, zero to us. That tends to get around." He switched to the long set and raised HQ. "Base, this is Donovan. Southwest forward base supply run intercepted and destroyed. Three vehicles. Report to follow." Sarah climbed down and crossed to Hills's wounded. One scout had a gashed arm. She cleaned it and closed it with a stimpak. Her gloves came away red, then she wiped them clean. The raiders' southwest base had lost its trucks and its cargo. The road home was emptier now. Sarah pinned the count to her pad and started planning the next drive.
