The past six weeks had changed everything.
At first, it was just theory, stacks of stitched booklets, diagrams tight as a scribe’s ledger, and the quartermaster’s gravel warning that theory is mercy. Siege engines, fortifications, bridges, mining, beast countermeasures, each subject its own slim volume, twenty or thirty pages that read like the bones of a new language. Most recruits groaned. To me, the pages felt like a locked door with a key already in my hand.
Every drawing was a puzzle waiting to be solved. Trebuchets balanced to the nail, torsion bundles coiled like a giant’s tendons, mantlets turning planks and canvas into a moving lie. The booklets didn’t just tell us what, they told us why. Angles, leverage, load, the hidden mathematics inside carpentry.
I copied plates by lamplight until my hand cramped. Trebuchet arms, ballista frames, trench cross-sections marked A for parapet, B for berm, C for drainage. I’d sketch, catch my mistakes days later, and redraw until the lines finally sat right. It wasn’t duty. It was joy, the clean click of understanding when shape and purpose became the same thought.
But it wasn’t the engines or trenches that seized me. It was the runes.
The Field Runes booklet looked plain, but every mark had teeth. A wood sigil etched shallow let timber stiffen and seal fine cracks, as though the wood remembered itself. A spark rune coughed flame into a priming cup, no fumbling, just heat when needed. A low earth mark kept trench walls from collapsing in the rain. A simple water cleanse kept barrels and canteens pure. They were soldiers’ tools, but to me they were elegance, the bridge between numbers and survival. If steel was the army’s fist, these were the tendons and bones. And somewhere in that balance, I fit.
When theory ended, the real work began.
The first afternoon we marched past the east classroom into the repair yards, it was like stepping into my own sketches made solid. Siege frames slept under tarps. Mantlet ribs leaned in rows. Rope coils hung like coiled serpents. Sawdust, oil, and the rasp of steel on wood hung in the air.
We were handed shovels, ropes, and toolkits. “Lines here, here, and here,” a private barked. “You, gabions. You, stakes. You three, dig me a profile that doesn’t make me weep.”
Most groaned. I hated the digging too, the way your spine forgets it was ever straight. But once we moved to mantlets and torsion bundles, the ache drained away.And when I first circled a trebuchet’s massive arm, rough-hewn and rune-scribed, it felt like standing at a shrine. I wanted to climb it, touch every join, trace the beams.
Which, in hindsight, is exactly what got me in trouble.
I’d only scrambled halfway up the frame when a voice snapped from below, sharp as a thrown nail. “You planning on taking her for a ride, recruit?”
I froze, hand on the sling pin. A stocky private with arms like bundled rope looked up at me, oil rag in one hand, the other already hooked in his belt like a man ready to haul a fool down.
“I, uh, just wanted to see the counterweight join,” I said quickly.
His glare deepened. “You want to see the join, you ask. You climb my engine without leave again, and I’ll tie you to the arm and use you as a test shot. Clear?”
Heat flushed my face as a couple of recruits failed to smother their laughs. “Clear, sir,” I muttered, scrambling down, boots sliding on wood polished by a hundred hands.
His mouth twitched once my feet hit dirt. He jabbed a thick finger toward the very pin I’d been reaching for. “Since you’re so curious, watch. That’s the release. It’s the difference between a stone that kisses a wall and one that fells it. Pin binds the sling; pin frees the sling. Mistime that, and you’ll scatter your own front line.”
I leaned in despite myself, throat tight with a stupid kind of gratitude. “Yes, sir. Thank you, sir.”
He snorted. “Enthusiastic idiot,” he said, but there was a ghost of amusement in it. “Back to your trench before I make you part of the counterweight.”
The others chuckled all the way back across the yard. I didn’t care. Even getting scolded felt like learning. Embarrassment fades quickly enough. The memory of that release pin, what it did, why it mattered, stayed sharp, carved into me like one of the runes on my practice scraps.
The days soon fell into rhythm. Trenches and ropes. Mantlets raised and toppled. Siege frames braced and tested, then braced again after the first joints sagged. We wove gabions until willow wicker left raw grooves across our palms. We bound fascines and learned the trick of twisting a lever-stick through the bundle to draw it tighter, so it wouldn’t unravel when dropped into a ditch. My hands burned, my shoulders ached, and every night I fell into my bunk with muscles humming like struck strings. And still, more often than not, I found excuses to linger in the repair yard.
The privates stopped calling me a nuisance, though they never treated us like equals. Maybe they saw persistence. Maybe they simply liked having willing hands. Either way, they let me stand close. I learned to oil ropes until each strand shone, to chase hairline cracks in beams with a candle flame, to set pegs where the wood had dulled. I discovered that a torsion bundle could be plucked like a harp string and that its pitch told you whether it was too dry. I learned that timber that drank oil too quickly was hiding rot, smiling smooth on the outside while hollow inside. And I learned the quiet satisfaction of a knot that held when weight pulled against it.
One sodden afternoon, they took us to a clay bank where a trench wall had slumped after a storm. The same private who’d barked at me on the trebuchet pointed with his stick. “Edge collapsed. Why?”
“Profile’s too steep,” someone called.
“Drainage channel’s blocked,” I added, hearing the booklet’s words in my head.
He gave a curt nod. “Both. Fix either and you last the night rain. Fix both and you might last until something steps on you.”
So we worked. Broadened the V, shaved the walls, scored a drainage line, packed it with brush. Then he made us pour buckets down the slope, watching where the water ran, where it lied. Clay lies often. You have to remind it of the shape you need.
Another day it was sound lines: shells and bone strung on wire at ankle height. A crude, ugly music. “Tier Ones don’t care,” the private told us. “But you will. Because sleeping and not sleeping are both better than dead.”
Bridges came after. Nothing grand, only rope-and-log crossings that groaned beneath your boots. Wet wood lied one way, dry wood another. They both lied. We tied knots until our fingers remembered before our minds did, square, clove, bowline. When someone used their teeth to snug a hitch, a stick rapped down. “Teeth rot,” the private said. “Knots don’t care.”
If you stumble upon this narrative on Amazon, it's taken without the author's consent. Report it.
And then came fire. A shallow oil ditch, a spark rune scratched into ceramic. A single touch and the trench whoomped to life. Not an explosion, but a sudden crawling line of flame that licked forward on a ripple of smoke. Heat kissed my face, warning more than hurting. Wind bullied it, trench shape steered it, and I stood transfixed. The fire was small here, but in my mind it stretched across a field, a wall of warning against something with too many teeth.
It was the same lesson in every disguise: the world will burn, fall, rot, or lie, unless you learn how to persuade it otherwise.
Evenings belonged to the fire in the yard and the comforting chorus of men talking themselves back down from the day. Leif, Henry, Erik, and Farid would find me without needing to look, same as always. Bowl in hand, back to the stone, legs gratefully remembering what it meant not to stand.
The talk ran in familiar grooves: Leif timing his sprints and cutting seconds until he wore the look of a boy measuring himself taller on a doorway, Vanguard or bust, always. Henry recounting some disaster in Supply where beans had been counted as barrels or barrels as beans, and how he would make sure the ledger sins stopped once he was the man holding the quill. Erik swore he’d never run a step more than required, then casually revealed he’d run two extra laps to keep up with Leif. Farid kept needling us all, trying to laugh off the nerves that showed in the way he talked about his coming Awakening, half excitement, half unease, as though the moment couldn’t arrive fast enough and yet not soon enough either.
And me? Sometimes I talked. More often, I carved.
One evening, I had a scrap of timber in my palm, small enough to hide, big enough to matter. Knife, shallow angle. Circle, line, hook. The simplest form of a spark rune. I didn’t hear Erik until his hand came down on my shoulder.
“BOO!” he barked in my ear.
I jumped so hard the knife kissed my thumb. The lines on the wood jerked into nonsense.
Leif nearly spilled his stew, laughing. Henry smirked without looking up. Farid gave a ridiculous half-bow that made me want to hit him with the spoon I didn’t have.
“You bastards,” I muttered, sucking my thumb. “I could’ve cut myself.”
“Could’ve?” Erik’s grin flashed. “Looked like you were about to anyway. Saints, Ed, you get so lost in those scribbles you forget the rest of us exist.”
“They’re not scribbles,” I said, more hotly than I meant to. I held up the ruined piece. “It was a spark rune. Used in boulder throwers to light pitch.”
Henry raised his brows. “So you’re trying to burn down camp with a stick.”
“Small spark,” I said quickly. “Enough for kindling. Safer than flint in a pinch. The manual-”
“The manual,” Farid echoed in a tone of deep wisdom. “Beware the man who cites the manual at suppertime.”
Leif leaned back, grin widening. “Careful, Scholar of Oxspell. Next thing, you’ll be building trebuchets out of soup spoons.”
I dug another scrap from my pouch, cheeks warm and hands steadying as they made their jokes. “Laugh all you want. You know those mantlets we were sweating under? There’s a wood mark you can add to the frame. Draws ambient mana into the grain, slows cracking. Half the reason the older ones haven’t fallen to splinters is because someone with patience sat and scratched lines where lines belong.”
“Behold,” Erik intoned, eyes closed. “Ed the Carpenter. Protector of Splinters.”
“Lord of Firewood,” Henry added.
“Goblin-slayer of Toothpicks,” Farid said, then dodged the pebble I flicked at him, the smug grin never leaving his face.
I couldn’t help it; I grinned too. “Mock me now. When your spear shaft snaps mid-charge and you’ve a choice between woodwork or getting eaten, I won’t be listening to any of you cry.”
“Don’t pretend you won’t fix it anyway,” Leif said, gentle where his words were usually iron. “You’ll fix it, and then you’ll give us a speech about lever arms until a sergeant finds you and makes you explain it again, standing on a crate.”
“I’ll need the crate,” I said innocently. “Not all of us are aiming to be seven feet tall with a polearm for a spine.”
That earned me a shove and a grin that lived in my chest longer than the push.
Their laughter ebbed to a comfortable murmur. I set the knife again. This time I didn’t hurry. Carving is a kind of listening. The blade wants to run with the grain, not fight it. The mark wants to be shallow where stress is high, deeper where it must drink. Circle intake. Triangle conversion. Upward hook for activation. The lines met the way the plate showed them meeting.
I pressed my thumb over the groove and let a pinch of mana dust trickle along the cut, the grains settling into the etched lines like fine sand into cracks. It wasn’t the right medium, not really, mana dust burned too hot, too fast, but for a heartbeat it was enough.
A faint hiss answered me. Then, pop. A spark leapt, a bright needle of heat, and the scrap smoked in my hand without truly catching.
Farid flinched. Erik swore. Leif froze, then laughed so hard he folded over his knees. Henry didn’t spill a drop but his eyes widened as if he’d seen a coin stand on edge and refuse to fall.
“Saints, Ed,” Erik said, half-scolded, half-awed. “Warn us before you start throwing fire around.”
I blew across the smoking scrap, pleased in a way I couldn’t hide. “See? Not just squiggles.”
Leif shook his head, still chuckling. “Scholar of Oxspell and fire-breather. You’ll be running the whole camp by next week.”
“Call me sir,” I said, lifting my chin.
Three pebbles hit me in three different places. Worth it.
Henry leaned over and nudged the scrap with his spoon. “Put that away before a sergeant sees and volunteers us to demonstrate ‘fire safety’ by digging a new water trench to the latrines.”
I tucked the wood into my pocket, obedient for once. The thrill sat bright behind my ribs, not only from the spark but from the clean fact of it: a mark carried from a page to a palm, behaving the way it had promised. Theory, then proof.
Around us, the yard’s sounds settled into the music of a garrison at night: a hammer somewhere in the blacksmith wing hitting a softer metal, a mule arguing under its breath, a chain clinking, men whose laughter had run out turning quiet because bed and morning had agreed between them to come early.
“Show me that wood mark tomorrow,” Leif said, eyes on the fire. “The one that stiffens the grain. If it keeps a spear shaft from splitting when I drive it, I’ll pretend to salute you.”
“Pretend?” Erik said. “You heard the man. Sir Ed.”
“Sir Ed,” Farid echoed gravely, then ruined it with a grin. “Savior of Toothpicks.”
“Go sleep,” Henry told us, but there was warmth in it, not command.
Not everything shone. Yet even in the misery, I began to notice something. The dirt complained, but it also taught. If you pay attention, the world pays back. A trench that drains is a promise kept. A knot that bites saves a life you’ll never meet. A pin that frees at the right breath can topple a wall and end an argument without shouting. Those weren’t just lessons in manuals, they were truths etched into every blister, every aching joint.
In quiet snatches I tested the Field Runes booklet wherever I dared. A faint wood mark along a tool handle, nothing official, nothing anyone had told us to do, yet it stiffened a split I’d seen creeping near the ferrule. The tool stopped biting wrong in the grip that held it. No one noticed. But I felt it each time weight met wood, an echo of the line I’d carved.
Once, walking back late past the sheds, I caught a private checking a ballista arm with a candle stub. He held the flame close, watching the reflection along the grain. When the light struck a hairline crack, the glow doubled and broke apart, a trick I’d have missed a month ago. I lingered longer than I should have, memorizing the tilt of his wrist, the patience of the test. When he finally looked up, I braced for curses. Instead, he snuffed the flame and jerked his chin at the door. “Lights out. You break your neck out here, I have paperwork.” The closest thing to kindness I’d heard in weeks.
Fifteen days of booklets hadn’t made me a hero. A month of practice hadn’t either. But day by day, something stubborn set its teeth in me. Where others saw grind, I found rhythm. Where they saw walls, I saw joints wanting hands with the right shape.
Later, lying on my bunk after the fire was stamped to coals, the day replayed itself: trenches and ropes, the trebuchet pin, the oil ditch whoomp, the spark that leapt because I asked. My friends’ futures already bent their way, Leif’s spear toward Vanguard, Henry and Erik’s quills toward Logistics, Farid’s boots toward the road. Mine wasn’t drawn. That should have frightened me. It didn’t. Between smoke, stone, steel, and sparks, I’d found a place with room for me.
