The red glow behind the sealed shelter grew brighter when JJ put her hand on the ice.
She kept her palm flat against the block and held still. The heat behind it pushed back, trapped and angry, but the ice between them stayed thick enough to turn the glow into a smear. The lever inside twitched once, then stuck in the same halfway position.
Ty kept his wrapped hand lifted and his good hand on the case frame. The front wheels had started to climb the softened ridge. Every inch scraped through the rail and into his shoulder.
"The case is going to force the ridge before the last line opens," Ty said. "If it climbs wrong, the glass tips toward the right shelter."
"Then the case will wait like a civilized coffin with unresolved manners," JJ said. "Blue, tell me where this door hurts before it teaches us."
Blue ran her fingers over the carved complaints. Meltwater had filled some of the cuts, making the words easier to read. Heat debt. Double shift. Locked rest. Docked rations. Each complaint had a small notch beside it, deeper than the letters, shaped for a tool strike rather than a key.
"These marks are more than worker writing on the ice," Blue said. "They are strike points around the emergency heat lever."
"Worker complaints are being used as a repair code here," JJ said. "That is either clever or unforgivable by design."
"Both remains a popular answer in this hall," Ty said. "How many strikes before the lever opens for us?"
Blue counted the notches with Marcus’s bit and touched each one.
"Four complaints, four strikes, then the lever should drop," Blue said. "The block is still too thick, so we hit the outside marks and let the shock carry through."
JJ looked at the complaint marks again. Her jaw worked once. The anger in her face stayed controlled, which made it worse. She aimed herself at the part of the room that deserved steel.
"Read them before I hit anything with the bit set," JJ said. "I want the room to know which debt is getting paid."
Blue nodded and set the bit into the first notch.
"Heat debt is first, workers charged for staying alive," Blue said.
JJ struck the end of Marcus’s bit with her sword pommel.
The ice block cracked around the first notch. The red glow inside brightened. The lever trembled, then held. The central pipe above them knocked once as heat tried to move and failed.
The case pushed harder against the ridge, and Ty planted his shoulder against the frame.
"The first strike woke the line, but the ridge is taking the pressure," he said. "Do the next one before the wheels choose for us."
Blue moved the bit to the second notch.
"Double shift is second, same cold and longer hours," Blue said.
JJ struck again before the heat could fade.
The second crack crossed the block and ran toward the viewing slit. Warm air leaked through the cut and touched JJ’s cheek. She stepped back half a foot, then returned her blade to the mark.
"I am giving this room very specific anger," JJ said. "It may appreciate the professional standard before I break it."
"Your professional standard is terrifying and currently useful," Ty said. "Please continue improving the workplace for everyone’s benefit."
Blue set the bit into the third notch.
"Locked rest is third, sleep turned into another trap," Blue said.
JJ hit the bit harder than the first two strikes.
The third crack broke into the viewing slit. A tongue of heat pushed through and melted a wet line down the front of the block. The lever inside dropped by a finger width, then caught again with a dull clank.
The case jolted hard enough to shake the straps.
The front wheels rode up onto the ridge. The right side lifted. Glass clicked against metal straps. Ty threw his good hand over the frame and shoved down with his forearm, keeping his injured palm high.
Pain ran through his shoulder into his teeth.
"The case is climbing right, and I need that last line now," Ty said. "I can hold the frame, but the rail is done waiting."
JJ looked at the fourth mark with the blade already moving.
"Docked rations is fourth, food taken after the cold," Blue said.
For the first time since they entered the hall, JJ smiled without humor.
"That one gets the edge because I can reach it," she said. "Move your hand away from the bit before I hit the mark."
Blue pulled back and kept Marcus’s bit clear.
JJ drove the sword point into the fourth notch and twisted.
The ice around the mark split open. Heat rolled out of the crack and shoved frost from the door in dirty sheets. The lever inside dropped the rest of the way with a heavy sound that traveled through the floor.
The sixth line woke angry, and every roof pipe knocked at once.
The ridge ahead collapsed into slush under the case wheels. The rail lurched forward. Ty slipped, caught the frame with his good arm, and dragged his weight backward to keep the case from running.
Blue grabbed the rear guide and skidded through meltwater.
JJ yanked her sword free and ran to the front.
"Slow the case before it learns enthusiasm from the heater," JJ said. "I refuse to be killed by labor reform."
"The rail is hot under the wheels now," Ty said. "It is pushing from all six shelters under the case."
"Can you ask it for less enthusiasm without using the bleeding hand?" Blue asked. "I enjoy that hand being wrapped and still attached."
Ty pressed his good palm to the rail beside the case. The heat came through fast. The mark in his wrapped hand pulsed anyway, tugging across his chest as if it wanted contact. He kept the bandaged hand high and made the other one listen.
The rail felt different warm, less stubborn and more reckless under Ty’s hand.
The heat had loosened old grease, old ice, and old restraint together.
"The six lines are uneven, and the sixth is burning hot," Ty said. "The last shelter is pouring too much heat into the rail."
"Of course anger overheats when nobody regulates it," JJ said. "That is why I usually give mine a job."
Blue splashed back to the sixth shelter and looked through the cracked door. The lever hung down inside, but a red-painted wheel sat behind it, turning too fast. The heat share had opened all the way because the old lock had been jammed for years and released in one ugly burst.
"There is a regulating wheel behind the lever," Blue said. "I can reach it through the cracked slit if I enjoy losing knuckle skin."
"I need the case held center while she bleeds less than I did," Ty said. "JJ, take the front left side before it climbs."
"I heard the part where my job is preventing expensive glass tragedy," JJ said. "That description suits my mood better than the alternative."
JJ took the front left corner with her shoulder low and sword flat across the guide. Ty held the right side with his good palm on hot rail and his elbow against the case frame. Blue shoved Marcus’s bit through the cracked slit and hooked the red wheel.
The wheel fought her through the cracked shelter slit.
Heat poured through the opening and reddened her knuckles. She kept hold. Her lips pressed into a hard line, and the muscles in her wrist stood out.
"The wheel is turning like it wants the whole hall paid at once," Blue said. "I need a count that does not sound hopeful."
"Four teeth back on the regulator wheel, then stop," Ty said. "The rail pressure drops every tooth from here."
"That was almost a useful answer from a wounded man," Blue said. "I will complain about the timing afterward with feeling."
She pulled the wheel one tooth back, and the rail slowed.
The second tooth settled the case under their hands.
The third tooth lifted steam from the ridge slush and made the ice shelters creak around them.
The fourth tooth stuck inside the old regulator.
Blue’s bit slipped. Her hand slammed against the cracked slit. She swore through clenched teeth and tried again. The case began moving faster before she caught the wheel.
JJ shoved against the front corner with both feet sliding.
"Blue, I believe in your hand for emotional reasons now," JJ said. "Do something rude with it immediately before the wheel wins."
Blue hooked the wheel with the bit and yanked.
The fourth tooth moved, and the heat line settled.
The case rolled off the collapsed ridge and onto clear rail. It continued forward, but at a pace that allowed Ty to walk beside it rather than fight it. The white shelters gave off little threads of warmth now, each pipe knocking in its own rhythm.
The sixth shelter door cracked farther open beside JJ.
Inside was a narrow bunk, a burned cup, and a wall covered in more complaint marks. Some had dates. Some had names. Many had only tally cuts where someone had run out of room or strength for letters.
JJ stood in front of it and lowered her sword.
"This room called it anger because grievance was too honest," she said. "I hate the person who named it less than the person who needed it named."
Ty looked from the shelter to the old body in the case.
The rail carried them forward through the meltwater. The old skull faced the sixth shelter until the curve of the track forced it ahead. Ty wondered how many rooms in this place had been built around people losing the right to say something simple.
The words stayed small in his head, cold, hungry, locked in, and he kept them there without turning them into a speech.
"We should keep moving before the ceiling joins in," Blue said. "The heat is balanced, but I do not trust the ceiling after that release."
The ceiling agreed by dropping a thin sheet of frost onto the rail behind them. It shattered where the case had been a few seconds before. JJ looked up and gave the ceiling a flat stare.
"I am taking that as consent to leave," JJ said. "The ceiling has made its workplace culture clear."
The far end of the hall opened into a straight white corridor. The heat from Igloo Nation faded behind them, and the air ahead sharpened again. The rail ran through the center, clean and narrow, toward a wall that looked smooth enough to be carved from one piece of ice.
The case slowed before the wall and settled on the rail.
Ty felt the change through his good hand. The rail under the wheels had stopped pushing. It waited, but not for heat, pressure, weight, or tags.
Something on the other side touched the wall.
A line appeared in the ice from floor to ceiling.
It was thin, clean, and almost too straight for machinery. No heat bled through it. No crack wandered away from it. The cut simply existed, as if the wall had accepted a decision from a sharper place.
Ty knew that kind of cut before anyone named it.
He had seen Rusuf make openings through things that were supposed to stay closed.
JJ saw his face and shifted her grip on the sword.
"Tell me that wall sliced itself because it felt left out," she said. "I would love that answer more than your expression."
The line widened by a hair as everyone held still.
Cold air moved through the slice and carried a voice from the other side.
"Ty, keep the case exactly where it is," Rusuf said from beyond the ice.
