Morning came without ceremony.

  The gold had been delivered the day before, hauled under armed watch into the Fort’s stone belly and sealed away behind runes Otwin did not trust. The transaction itself had been clean. Receipts issued. Signatures stamped. No sudden betrayals. No alarms. If the bank had been involved in the ambush, it had paid a real price for it. Dead guards had been carried out under sheets. The courtyard stones still bore scorch marks where explosives had gone off too close to the walls. Banks did not like losing men or having their property damaged. Otwin took some comfort in that. Not much, but some.

  The Ol' Five Seven sat inside the Tower Drome like a caged animal, squat and broad and scarred already despite having never left the city walls. Her hull plating was a patchwork of recovered iron and bronze sheets, riveted and welded with care that bordered on affection. The lift stones hummed faintly in their housings. Steam lines ran warm along the flanks, venting in slow, cautious breaths. This was her first real day. Her maiden voyage, if one wanted to be poetic about it.

  Otwin did not feel poetic.

  He stood on the drome floor with his helmet tucked under one arm, watching mechanics crawl over the fort’s hull like ants. Engineers shouted measurements back and forth. Someone swore loudly when a wrench slipped and cracked knuckles against plating. The air smelled of oil, hot metal, and old stone. Familiar smells. Honest ones.

  Grump stood near the forward access ramp, arms folded, face set in the stubborn expression Otwin remembered from their Army days. He looked older now. They all did. Years of scavenging and compromise had a way of carving lines into men that no amount of rest ever quite erased.

  “You should have tested her,” Otwin said.

  Grump glanced over, then back at the fort. “We did.”

  Otwin shook his head. “No. You assembled her. You powered her up. You rolled her around a bit. That’s not a test.”

  Grump’s mouth twitched. Not quite a smile. “She runs.”

  “That’s not the same thing.” Otwin stepped closer, lowering his voice. “Cocoa Road isn’t a shakedown run. It’s not forgiving. You don’t take a first build onto that stretch unless you’re desperate or stupid.”

  Grump finally turned to face him fully. “Which one do you think I am?”

  Otwin held his gaze. “Desperate.”

  Grump nodded once. “Good. Then you’re paying attention.”

  He gestured toward the open side bays of the drome, where cargo was still being loaded. Crates of dried food. Barrels of treated water. Medical chests stamped with old Army sigils. Spare valves. Reinforced steam piping. Replacement drive components. More than Otwin had expected.

  “I sank everything,” Grump said. “Everything. Sold off the last of my private salvage. Took loans I’ll be paying until I’m dead if this goes bad.”

  Otwin frowned. “The warehouse.”

  Grump’s eyes flicked away for a fraction of a second. “Mortgaged it.”

  Otwin let out a slow breath through his nose. “You didn’t tell me that.”

  “I wasn’t asking permission.”

  Otwin looked back at the cargo. The warehouse had always been Grump’s anchor. A place to fall back to. A holdfast. Half full now, he realized. Half emptied to make this run possible.

  “You understand what that means,” Otwin said.

  “I do.”

  “If this goes wrong, you don’t just lose the fort.”

  “I know.”

  “You lose the warehouse. Your people lose work. You don’t get a second try.”

  Grump’s jaw tightened. “That’s why there isn’t time to test her out on some gentle stretch of rail. That gold doesn’t sit. Not now. Not after yesterday. If we wait, someone else moves. Or someone bigger takes notice.”

  Otwin studied him for a long moment. He saw the fear there, buried deep and kept under control by habit and pride. He saw resolve, too. The kind that only showed up when the bridges were already burning behind you.

  “You should have said,” Otwin said quietly.

  Grump met his eyes again. “You would have walked.”

  Otwin did not deny it.

  They stood there in the noise and heat of the drome, old soldiers facing a problem with no good solutions left. Finally, Otwin nodded once.

  “Alright,” he said. “Then we do this clean.”

  Grump’s shoulders loosened just a fraction. “I knew you’d say that.”

  “Don’t flatter yourself,” Otwin replied. “I don’t like it. I don’t approve of it. But I won’t half-ass it.”

  “That’s all I’m asking.”

  Otwin turned away, slipping his helmet on and sealing it with a practiced motion. The Stormtrooper armor settled around him, weight familiar and wrong at the same time. He pushed the thought aside.

  He began his final security checks.

  Love this novel? Read it on Royal Road to ensure the author gets credit.

  He walked the perimeter first, boots ringing against the drome’s stone floor. He checked sightlines from the open doors. He memorized shadows. He noted the positions of drome guards and where they were not standing. He ran through fields of fire in his head, marking where an ambush would hurt the most and where it would fail.

  Inside the fort, he inspected crew stations, checked restraints, and tested comms. Humbert and Jordy acknowledged him with curt nods. Doke was elbow-deep in a maintenance panel, grease smeared across his cheek. Paul checked medical stores with methodical care, inventorying twice without being asked.

  Otwin paused at the rear access hatch, resting a hand against the hull. He could feel the vibration of the engines idling low, the lift stones pulling gently against gravity. The DAC’s readouts flickered at the edge of his vision, silent unless called upon. He ignored them for now.

  This was not the moment.

  He climbed back down to the drome floor as engineers finished their work. Final bolts were tightened. Panels sealed. Tools cleared away. One by one, mechanics retreated from the hull, some patting the plating as they went, a superstition as old as moving machines.

  Grump stood at the command hatch, hands resting on the rail. He looked smaller there, framed by iron and steam and stone. Otwin took up position near the forward guns, scanning the widening gap as the drome doors began to move.

  The doors were massive slabs of reinforced stone and steel, etched with old sigils meant to discourage sabotage. They opened slowly, grinding aside with the sound of weight being persuaded rather than forced. Cold morning light spilled in, cutting through steam and dust. Beyond the threshold lay the rail. Beyond that, the road.

  Engines spooled higher.

  The Ol' Five Seven breathed in, steam venting in controlled bursts. The lift stones brightened. The fort settled into balance, ready.

  Otwin squared his shoulders.

  The doors finished opening.

  The engines roared.

  ***

  The Ol’ Five Seven rolled forward with a low, gathering rumble, iron treads biting into the stone apron beyond the Tower Drome doors. Steam vented in controlled bursts along her flanks, white clouds catching the morning light before being torn apart by motion. The massive doors stood fully open now, framing the Wild Lands beyond like a wound cut into the world.

  Otwin stood near the forward interior station, one hand braced against a support rail, feeling the machine come alive under him. There was a difference between engines spinning freely in a drome and engines committing to movement. He felt it in his boots, in the vibration carried up through the deck plates, in the way the hull seemed to settle into itself once the treads found purchase.

  They crossed the threshold without ceremony.

  Outside the walls, the land opened up into broken stone and scrub, scarred by old track marks and half-buried wreckage. The Ley-Rail cut through it all in a broad, rune-carved band of dark stone, faintly luminous where the energy coursed beneath the surface. The Ol’ Five Seven aligned with it smoothly, the lift stones adjusting automatically as the fort’s weight shifted. Power flowed in, steady and unbroken.

  Otwin glanced at the internal readouts. The power stone remained fully charged.

  “That still feels wrong,” he muttered.

  The engineer assigned to the forward systems station, a lean man named Keller with oil-stained gloves and a permanently furrowed brow, looked over. “What does?”

  “Running full draw without depletion.”

  Keller snorted. “That’s the Rail doing its job. We’re not burning stored charge right now. We’re sipping straight from the source.”

  Otwin watched the numbers hold steady as the fort gained speed. The Ley-Rail pulled at them gently, like a current in deep water. Southward. Toward the Hegemony.

  Not where they were going. But it'll get them where they're really headed.

  They would follow the rail for a time. Everyone did. It was safer. Faster. Predictable. Then, when the terrain and timing allowed, they would peel west onto the Cocoa Road and let the real danger begin.

  Otwin shifted his weight and looked around the station. Crew were settling in, voices low, movements efficient. No one was relaxed, but no one was panicking either. Veterans, all of them. He found his gaze drifting back to the power readouts.

  He cleared his throat. “Hey. Keller.”

  “Yeah.”

  “I know the basics. Army-level basics. But I was never an engineer.”

  Keller raised an eyebrow. “You want the short version or the long one.”

  “Short,” Otwin said. “I’m on duty.”

  Keller nodded and tapped the side of the console. “So. The power stone doesn’t run the engine directly. It powers the heat stones.”

  Otwin nodded slowly. “So the power stone powers the heat stones, which heat the boilers, which push steam to the engine and powers it. That about right?”

  “Sort of,” Keller said.

  He leaned back slightly, clearly settling into the explanation despite himself. “The stones heat the boilers, which boil the water to create high-pressure steam. That steam pushes pistons back and forth in cylinders. That linear motion gets converted into rotational power through connecting rods and cranks. That rotation drives the tread assemblies and any other machinery tied into the shaft. Valves control the steam flow, so the push-pull action repeats instead of just blowing everything apart. In essence.”

  Otwin blinked once. “Oh.”

  “Yeah.”

  “Yeah, that’s more than I ever knew.”

  Keller smirked faintly. “Don’t worry. Most people don’t understand it. If it wasn’t for the power stones, we’d need a furnace and coal or something else to burn for the boilers. That’s what the old designs used. Messy. Heavy. Slow.”

  Otwin nodded, eyes still on the Rail sliding beneath them. “So why doesn’t steam armor actually use steam power. I know they use power stones and that the steam boilers would be bulky. But the STVs use a small boiler system.”

  Keller laughed, a short bark of genuine amusement. “Because that would be a nightmare. Steam Armor really shouldn’t be called that. It’s not steam at all.”

  Otwin looked over. “Yeah, I know that. But what's so different about the armor than how the engines of the fort work?”

  “Well, inside the armor is a series of magically artificed muscle fibers under the plating,” Keller continued. “The power stone feeds into a converter that sends electrical pulses through those fibers. They contract and relax like real muscle, just stronger and faster. That’s what moves the armor. No pistons. No boilers.”

  “Huh.”

  “It’s power-intensive,” Keller added. “Which is why you don’t see Steam Armor operating far from Ley-Rails or Ley-Wells for long. You drain the stone dry otherwise.”

  Otwin exhaled. “Ah. I figured it was something like that, but never really had the clearance within the Army to ask for more information.”

  “Yeah,” Keller said. “I was an Army armor tech. This stuff isn’t really a secret anymore. Just not spread around much.”

  “Gotcha.” Otwin nodded once. “Thanks.”

  “No problem.”

  Keller turned back to his instruments, conversation apparently finished. Otwin let it sit. The explanation had filled in gaps he had never bothered to question before. Machines were machines. You trusted them, or you didn’t. Knowing why they worked did not always make them safer.

  The Ol’ Five Seven continued south, her pace steady, treads humming as the Ley-Rail carried them onward. The Wild Lands slid past on either side. Sparse vegetation. Cracked earth. The occasional rusted carcass of something that had failed to make the journey.

  Otwin moved away from the station and climbed toward an observation point, pausing to look out through reinforced glass. The Rail curved gently ahead, disappearing into the haze. Somewhere beyond that horizon lay the Hegemony, with its old laws and older machines. They would not reach it. Not this run.

  West lay the Cocoa Road. Broken. Lawless. Hungry.

  The fort did not know that yet.

  The power stone remained full, its draw perfectly balanced by the Ley-Rail beneath them. For now, the Ol’ Five Seven did not need to consume herself to move. For now, the road was generous.

  Otwin rested his hand against the bulkhead and felt the steady thrum of motion.

  They were underway.
