Dara's face was on the wall of every checkpoint in Blightmire, and she needed to walk through one of them. The poster showed her in the cracked plague mask she wore to hijack the regime's loudspeakers. For three months she had piped forbidden songs across the ruins from a stolen tower. Now she wanted something bigger. The last living musician from before the regime sat in the fortified camp, and she meant to smuggle him to her hidden studio. But the camp gate demanded transit papers she did not have, and any guard who saw her would drag her off in chains. She climbed to the old broadcast tower loft to think. Rust flaked under her boots. Broken glass littered the floor by the dead control panel. That was where she found the old man. He crouched over a roll of yellowed paper spread across a crate. His white coat was stained gray. His hands never stopped moving, smoothing the paper flat, tracing lines with one cracked fingernail. He did not look up. "You're the singer," he said. "You broadcast from my tower. Loud. Sloppy wiring." "Who are you?" "I drew these walls." He tapped the paper. "Every gate. Every guard post. The regime paid me to keep people locked in." His mouth twisted. "They never checked my work close enough." Dara knelt beside him. The paper was a map of the containment walls. Neat ink, careful numbers. Then she saw it. Near the camp, one drainage line ran under the wall and out the far side. It was marked as sealed. A small note in the margin said otherwise. "This tunnel," she said. "It's open." "I built it open." Eli met her eyes for the first time. His were sunk deep and tired. "I always meant one way out. I was too much a coward to use it." Dara's chest went tight. No papers. No checkpoint. No posted face at a gate. "Show me where it opens," she said. He rolled the blueprints and pressed them into her arms. "The mouth sits past the wall, in the wet ground beyond the wire. You crawl in from the outside. It brings you up inside the camp yard, behind the water shed." "You're giving me these?" "I'm coming with you." He stood, knees cracking. "I know the flaw better than any drawing. And I've waited long enough to spend it." That night they left the tower. They followed the blueprints across broken ground to the wall's shadow. Behind a fallen slab, Dara found the tunnel mouth, half choked with mud and reeds. Water trickled from it. The way was open, exactly as Eli had drawn it. She no longer needed papers. She no longer needed the gate. But the tunnel ran under the most guarded ground in Blightmire, and it would bring them up inside the camp, on the wrong side of the wire, with no way back out the way they came.

The tunnel swallowed the last of the outside light. Dara crawled forward on her hands and knees, Eli close behind. Water soaked through her jumpsuit. The dark was total. She could not see the walls, the floor, or her own fingers. One wrong turn would drop them into a side shaft or a flooded pit. She needed light. But above them, the ground carried guards, and the smallest glow would leak up through a crack and give them away. "We can't crawl blind," she whispered. "And we can't light a flame." "No flame," Eli said. His voice came from just behind her boots. "The vents run straight up. A lantern down here is a torch in the yard up there. They'd see it in a breath." They stopped. Ahead, faint and steady, a voice reached them through the stone. A woman, reading. Grain totals. Victory numbers. The same flat words the regime piped out every morning. Dara knew that broadcast. It came from the tunnel entrance overhead, where a thin woman in a red jacket read the daily lies into a crackling microphone. Wren Joss. Dara had heard her voice a hundred times and hated it. Then the reading stumbled. The woman above them slowed. Her voice dropped, close to the vent, as if she leaned toward it. "Sector Seven," she said. "The real number is half." A pause. "I've kept both hands flat on this desk for three months. I'm tired of it." Eli gripped Dara's ankle. "She knows we're down here." Dara's heart slammed. But the woman above did not shout for guards. She kept talking, low and plain, only into the vent. "There's a lamp in the water shed. Blue glass. The guards read it as a signal light. Harmless. It won't give you away." A breath. "Take the left fork. The right one floods." "Why help us?" Dara said toward the ceiling. "Because I finally said one true thing," Wren said. "Now go, before I lose my nerve." Her footsteps moved off. Dara crawled left, one hand tracing the wet wall. The fork split exactly where Wren said. The right passage gurgled with black water. Dara took the left. Twenty feet on, her fingers found a low shelf, and on it a small lamp with blue glass. She struck it. The glow was dim and cold, no bigger than a coin, but it lit the tunnel floor. Eli's face appeared in the blue light, wet and gaunt. "That color reads as regime," he said. "Clever. She's braver than her broadcasts." Dara could see now. She could move. But the light showed her something she had not counted on. Ahead, the tunnel narrowed to a rusted grate, bolted shut across the passage. Beyond it, the way ran on toward the camp. The blind dark was solved. Now a locked iron gate stood between her and Kael, and she had no key.

The blue lamp lit the grate, but the air had turned foul. Dara's mask filter had clogged with tunnel damp. Each breath came slow and wet. She sucked hard, and only a thread of air came through. The cracked rubber pulled tight against her face. Her chest burned. Beyond the bolted grate lay Kael. She could not reach him if she choked here first. "My filter's dead," she said. Her voice rasped inside the mask. "I can't breathe." Eli grabbed her shoulder. "Take it off." "The air down here is worse than the tunnel above." She coughed. "It'll drop me." He pointed at the clogged filter with a shaking finger. "Then clean it. The damp packed the mesh. Scrape it out." Dara pried the filter loose. Her fingers slipped on the wet rubber. Inside, the mesh was choked with black sludge. She dug at it with her thumbnail. It smeared but did not clear. Her lungs screamed for air. Spots swam in the blue light. Eli tore a strip from his stained white coat. "Wrap this over the housing. Cloth breathes. Sludge doesn't." She held her breath and worked fast. She scraped the worst of the sludge onto the tunnel floor. Then she stretched the coat strip across the empty housing and pressed the filter back over it. Her hands were black to the wrist. She fit the mask to her face and pulled in a breath. Air. Thin, but clean. It moved. She dragged in another and another. Her vision cleared. The burn in her chest eased. "It holds," she said. "For now." Then a voice came down through the vent. Not Wren's. A man's, flat and clipped, giving orders to guards above. "Check the shed. Lamp's not on its hook." Boots crossed the stone overhead. "Somebody moved it. I want to know who." Dara froze. She knew that voice from the checkpoint line. Garn Kessler. The broad enforcer who barked at the crowd outside Iron Regime Hall. His words came right through the vent, close enough to touch. "Nobody passed my post," Garn said. A pause. His voice dropped, harder. "Nobody. That's what the report says." A door slammed above. Dara heard him stop, half a breath, before he spoke again. "Search the tunnel mouth. If it's flooded, good. If it's not, you go down." Eli pressed against the wall. "They're coming for the tunnel." Dara stared at the bolted grate. The sludge from her filter lay in a black smear on the floor, plain as a footprint. Guards with lamps would read it in a second. She could breathe again. But now the blue lamp was missed, and a search was moving toward them. The grate was still locked, and the enemy was closing from behind.

The black smear on the tunnel floor would betray them. Dara pressed her back to the cold stone and listened. Boots moved above, but she could not count them. One set? Four? She could not tell how many Kessler had sent, or how close they were. Guess wrong, and she would crawl straight into their lamps. She needed his position, and she needed it now. Eli gripped the blueprints against his chest. "We can't move blind," he whispered. "We pick wrong, we die." Dara looked up at the vent slit. Sound came through it clean. She had heard Kessler's orders through that gap. If she could hear him, she could track him. She pressed her ear to the metal and held her breath. Kessler's voice dropped down, flat and clipped. "You. Shed. You two, the mouth." A pause. "I stay on the line." So he sent them in two directions. Not one search. Two. And the enforcer himself stayed above, near the tunnel entrance. Then the metal doors of the hall slammed shut somewhere behind him. Dara heard it clear. And she heard Kessler stop. A half breath. His voice cut off mid-word. She knew that flinch. She had watched him at the checkpoint, barking at the crowd, going still every time the doors banged. Half a second where he saw nothing. "He freezes," she breathed. "When the doors slam. Just for a moment." Eli stared at her. "You can't use that. You can't hear his doors from down here." "I can hear the guards' boots." She traced the two paths in her mind. One set moved toward the shed, right. One set moved toward the mouth, left. The mouth path crossed above the smear. "Two men going left. That's the direction we can't take." She pointed the other way, past the shed side. "We go where he sent one man, not two." She waited. The boots split. Two pairs faded left. One pair scraped toward the shed and stopped, searching a corner. That was the gap. Dara pulled Eli by the sleeve, low and fast, along the wall away from the mouth. They passed under the shed vent while the lone guard rattled the empty lamp hook above. They reached a bend the boots had not touched. Dara stopped and listened again. No lamp light spilled down. No shout came. She had counted them right. Three guards, split, and none in front of them now. But the bend did not open toward Kael. It curved back to the bolted grate, the same rusted grate that still stood locked between her and the musician. She had dodged the guards. She had not dodged the iron. Dara knelt at the grate and drew the slim lock pick from her sleeve. The guards were behind her now, moving the wrong way. She had bought minutes. She fit the hooked tip into the lock. This time nothing stood at her back.

The lock gave under the pick with a soft click. Dara pulled the grate open and slipped through. Beyond it, the tunnel opened into a low room of gray stone. Cold air pressed against her mask. She had crossed under the wall. She stood inside the camp now. But the camp was a maze of cells and corridors, and she did not know which held Kael. She could not search every door. One wrong turn would drop her in front of a patrol. She crouched in the shadow and listened. Boots. Not marching. Light steps, steady, the sound of someone who belonged here. Then a woman came around the corner with a clipboard in one hand. She wore a stained kitchen apron. She stopped when she saw Dara, and her mouth opened, but no cry came out. "You're not a guard," the woman said. Her voice stayed low and flat. "Guards don't hide." Dara did not move. "I'm looking for the musician. Kael Prent." The clipboard dropped an inch in the woman's hand. Something changed in her face. "Why." "To get him out." The woman crossed to Dara fast and gripped her sleeve. "Elara," she said. "I bring him food. I've been trying to find a way out for a month." She glanced back down the corridor. "He's below. In the cellar. Not this floor." Dara's chest tightened. She had crawled all this way and Kael was one floor down, behind a locked steel door she had not seen yet. "Take me to him." Elara shook her head. "Not now. Shift change is coming. Two guards walk this hall in minutes." She named it plainly, without fear in her voice, though her hand shook against Dara's arm. "You go back through your hole. Wait." "I can't wait. I'm this close." "You're this close to a cell of your own." Elara pressed the clipboard flat against her own chest, the way a person steadies a thing that won't stay still. "I feed him at dawn. No one questions me in the cellar. I check the root vegetables." A thin smile. "Come at dawn. I'll leave the cellar door unbolted. You'll walk right to him." Dara heard the boots then, far off, growing. Two sets. The shift Elara had warned of. She backed toward the grate. "Dawn," Elara said. "The door on the low level, black steel, red light above it. I'll kill the bolt." She turned and walked toward the boots, clipboard raised, already the trusted woman with a task. Dara pulled the grate shut behind her and pressed low in the tunnel. She knew where Kael was now. She had a way in. But the way in belonged to someone else's hands, and the guards would change again by dawn. She had traded blind wandering for a locked steel door and a promise she could not test until morning.

Dara waited in the tunnel until the dark thinned to gray. Then she crawled forward and pushed the grate open. Elara had promised the cellar door would be unbolted at dawn. If it was, Dara would walk to Kael. If it stayed locked, she would stand in an open corridor with no shadow to hide in, her wanted face plain to any guard who passed. She climbed out and dropped into the stone room. Cold air pressed her mask. Ahead, the corridor ran straight to a low stair. She took it down. At the bottom waited the door Elara had named. Black steel. A red light burned above it. That light meant the bolt was thrown. Dara's stomach dropped. She crossed to the door and pushed. It held. Locked. She pressed her ear to the metal and heard nothing. Somewhere above, boots scraped. A shift starting. She had no cover here, and the promise had failed. Then a key turned on the far side. The door swung in. Elara stood there, clipboard against her chest, apron stained. Her hand shook, but her face was calm. "They changed the lock last night," she said. "New cylinder. My key still fits." She stepped back to let Dara through. "The light stays red. That's the trap. Everyone thinks it means locked." Dara slipped inside. Elara shut the door soft behind them. The cellar dropped away in cold stone lines. Down a short passage, behind a grate, a man sat against the wall. Thin. Gray-faced. His head lifted at the sound. "Kael," Elara said. She knelt at the grate. "This is the one I told you about." Kael looked at Dara. His voice came out cracked. "You played the trumpet. Across the whole city." A weak smile. "I heard it down here. That bent note at the end." Something tightened in Dara's throat. "I came to get you out." She pulled the lock pick from her sleeve and set the hooked tip into the grate's lock. Her hands stayed steady. Elara held the clipboard flat, watching the stair. The pins gave one by one. The lock clicked. The grate swung wide. Kael tried to stand and could not. Dara caught his arm. He weighed almost nothing. Then a bell rang above them. Sharp. Three strikes. Elara went white. "Morning count," she said. "They count the prisoners at first light. I forgot the new schedule." She stared at the empty cell, then at Kael in Dara's arms. "His cell reads empty in four minutes. They'll seal the camp." Dara looked at the stair, then the tunnel far behind, then the frail man she could barely lift. The door was open. Kael was free of the cell. But the count had started, and she could not carry him back through the tunnel before the whole camp locked down around them.

Four minutes. Dara held Kael against her chest and did the math. She could not carry him through the tunnel before the count ended. When the guards reached the empty cell, every door would seal. She needed the count stopped, and she could not do that from the cellar. But she had one thing the regime still trusted. The stolen broadcast keycard hung inside her jumpsuit, warm against her ribs. "The broadcast desk," Dara said. "Above the tunnel mouth. Who reads the morning count?" Elara's eyes went wide. "Wren. She calls the numbers over the speakers so the whole camp hears." She gripped the clipboard tighter. "If the count doesn't come, the guards wait." Dara knew the name. Wren Joss, the thin woman in the red jacket who read the regime's lies every dawn and pressed her shaking hands flat to keep them still. Wren had once steered Dara toward a hidden lamp when it cost her everything to do it. She was scared. She was also on their side. "Get Kael to the grate," Dara said. She set him in Elara's arms. "Wait for me there. Don't move until you hear the speakers." Dara ran. Up the stair, down the cold corridor, into the stone room where the tunnel opened. She climbed. Her filter rasped with each breath. At the top waited the broadcast desk, wedged into the dark mouth of the entrance. Wren sat there, red jacket bright against the rock, a microphone crackling under her hands. Wren looked up and did not flinch. "They're counting," she said. "I read the numbers in ninety seconds." Dara pulled the keycard free and set it on the desk. "I have the last musician. He's below. If you call the count, they seal the doors and we die down there." Wren stared at the card. Her hands lay flat on the wood. They shook. "If I read a false count, they'll know it was me." "I know," Dara said. She did not soften it. Wren pressed the microphone switch. Her voice went out over every speaker in the camp, steady and clear. "Morning count complete. All prisoners present. Cells secure." She read it fast, the way she always read the things she could not bear. Then she lifted her thumb. Above ground, boots that had been moving toward the cellar stopped. The camp settled back into its dawn routine. No lockdown bell rang. Wren picked up the keycard and pushed it into Dara's hand. "Take it. When they check the tape, my voice is on it. I can't broadcast here again." She stood and shed the red jacket. "I'm coming with you now, or I'm caught alone." Dara understood. The count was dead. The doors stayed open. But Wren had burned her cover to buy it, and now three of them had to reach the tunnel before anyone reviewed that tape.

The count was dead and the doors stayed open. Now three of them had to run. Dara half-carried Kael down into the stone room where the tunnel opened. Elara waited at the grate. Wren followed, her red jacket gone, her thin arms bare in the cold. Beyond the grate ran the tunnel, black and low and narrow. Kael saw it and stopped. His eyes went wide. "No," he said. "I can't." Dara turned. Kael was the man she had climbed towers for, the last real musician, the one who had heard her trumpet cross the city from inside his cell. Now he stood shaking at the tunnel mouth. His breath came fast and shallow. His hand gripped the wet stone. "I haven't seen out in a year," he said. "That's smaller than my cell. I can't go in there." Dara understood. If he froze inside the grate, his body would plug the only way out. All four of them would die behind him. She had picked that lock to reach him. He was about to seal it with fear. Elara stepped close. She took his face in both hands. "Look at me," she said. "Not the hole. Me." Her voice stayed flat and low, the way she talked to him through the grate every night with bread in her hand. Kael looked. His breath slowed a little. But his feet did not move. Wren knelt at the grate. "It's narrow for twenty feet," she said. "Then it opens. There's a cart on rails at the far end." She said it plain, no comfort in it. "I read the maps for a year. I know the numbers." Dara pulled the mask filter she had spared and pressed it to Kael's chest. "Hum," she said. "You told me you heard my trumpet from the cellar. So sing. One note. Keep it going and crawl to the sound of it." Kael stared at her. Then he hummed. It was thin and cracked, a bent note that dipped at the end, the same shape her old trumpet recording made. Dara went in first. "Follow my boots," she said. "Don't stop the note." She crawled. Behind her the humming came, ragged, breaking, starting again. Elara pushed at Kael's feet. Wren came last. The note wobbled. Twice it stopped, and Dara froze, waiting, until it started once more. Stone scraped her shoulders. The dark pressed close. Then her hands hit open air. The tunnel widened. Dara stood and pulled Kael out by the wrists. He came free of the grate and dropped to his knees on the rock, still humming, tears on his face. Ahead sat the pedal cart on its rails, waiting to carry them under the wall. Kael had not frozen. The way out stayed open behind them. But dawn was over the camp now, and somewhere above, a guard would soon feed Wren's false tape into a machine and hear her voice.

The cart carried them under the wall and out. Dara pedaled until her legs burned, Kael slumped against her side, Eli hunched over his blueprints in the back. When the rails ended, they climbed and ran. The old broadcast tower rose ahead, rusted and empty, its ladder bolted to the frame. Dara had made her studio in its loft a year ago. She helped Kael up the rungs one at a time. He was breathing wrong now, too fast, too shallow. She had freed the last musician in Blightmire. She might carry him home dead. Inside the loft, she laid Kael on the battered cot. Its patched blanket smelled of mildew. His skin had gone gray. He touched his own ribs and winced. "They kicked me," he said. "Weeks ago. It never healed right." Each word cost him air. Dara pressed her hand to his side and felt the heat under his shirt. Something was wrong deep in his chest. "Eli." She turned. "I need supplies. Anything." Eli set down his roll of blueprints. He crossed to a dented cabinet in the corner and pried it open. Inside sat a white case marked with a red cross, its shelves neat with rolled bandages, small bottles, and a strip of pills. "Left here before the towers emptied," he said. He did not soften it. "I can't fix a lung. I can slow the fever." He knelt by the cot and worked with steady hands. He cleaned the bruise, wrapped the ribs tight, and shook two pills from the strip. "For the pain and the swelling," he said. "He needs a real doctor. This buys days, not more." Dara lifted Kael's head. He swallowed the pills with a sip of water. His breathing eased, slow by slow. The gray in his face pulled back a little. She held his wrist and felt the pulse steady under her fingers. "You'll live," she said. It was half a question. Kael opened his eyes. "You're the trumpet," he whispered. "I heard you through the stone. I thought I made you up." A small breath, almost a laugh. "I want to play again. Before I can't." Dara held his hand until he slept. Then she stood and looked at Eli. He was rolling the strip of pills closed, counting what was left. "How many days?" she asked. "Four. Maybe five." He met her eyes. "After that the fever comes back and I have nothing for it." The loft went quiet but for Kael's breathing. She had gotten him out of the camp and out of the wall. He was alive on her cot. But alive was borrowed now, measured in a handful of pills. Dara looked at the sleeping musician she had climbed towers to save. To keep him, she would have to find a doctor in a city that wanted them both dead.

Kael slept through the night, but his breath went ragged again by dawn. Dara counted the pills. Four left. She needed a doctor, and she needed one today. She pulled the checkpoint list from her jacket, the fresh poster Eli had torn from a wall on the way in. Her own face stared up at her. Beside it now: Eli's, Wren's, Elara's, Kael's. The regime had named her whole group. She could not walk one street to find help without a guard knowing every face. Eli spread his blueprints on the floor. "You can't go out that door," he said. "None of us can. They'll have your route memorized by noon." He tapped a thin line at the map's edge. "But I built more than one way under this city. There's a trail past the old rail cut. It runs behind the checkpoints, not through them. A doctor keeps a shelter at the end of it. Holt Prine. He owes me." "Then I take the trail," Dara said. "Alone you'll walk right past his door. You've never seen it." Eli rubbed his jaw. "He hides it well." A small voice broke in. "I know the trail." Dara turned. In the corner sat the girl who had followed them from the tunnel and then vanished into the dark. She had come back in the night. Her shaved head caught the gray light, the barcode dark on her neck. Her feet were still caked with swamp mud. She had not spoken a word since the tunnel. Dara had thought she never would. "Calla," Dara said softly. Calla did not look at Kael. She looked at her own muddy feet. "They marched us down it. To the shelter. I remember the turns." Flat, plain, each word set down like a stone. "I watched people cry on that trail. I did nothing." She stopped. "I can walk it with you." Dara knelt in front of her. "You don't have to." "I want to." They left through the tower's base drain, out of the guards' sightlines, and found the trail past the rail cut. It wound through packed earth and dead leaves, roots crossing it like ribs. Calla led. At each fork she paused, then chose. Her bare feet made no sound. Twice they heard boots on the road above and froze against the stones until the sound passed. The trail ended at a low mound of earth. Calla pressed a root aside. A door showed behind it, and Dara knocked the pattern Eli had made her memorize. A hollow-eyed man opened it, took one look at Dara's masked face, and went pale. "Eli sent me," she said. "A man is dying. Bad ribs, bad lung." Holt Prine looked past her at Calla, at the trail, at the empty road. Then he grabbed a bag. "Show me," he said. Dara had her doctor. But he had seen her face, and the trail ran both ways now.
