For the first time since Thornrock's walls had first risen from raw stone, the fortress stopped sleeping entirely.
From the moment grey light touched the eastern ridge until long after the last torch burned low each night, the sound of hammers rolled continuously through every street and courtyard — a rhythm that had, within days, become as much a part of the fortress's heartbeat as the wind moving through its watchtowers. Blacksmiths worked in rotating shifts at Old Ferrin's forges, hundreds of fresh arrowheads taking shape under hands that no longer needed to think about each strike before making it. Carpenters shaped thick wooden stakes by the hundred, sharpening points that would soon be driven deep into hidden trenches. Stonecutters hauled boulder after boulder toward the walls, their backs bent under labor that would, within days, become the fortress's first line of answer against anything foolish enough to test it.
No hand went unused. Children too young for the walls bundled arrows into neat, countable sheaves. Women braided bowstrings and stitched leather into armor that would need to hold against blades sharper than anything Titanblood had faced before this season. The elderly repaired broken tools and kept the cook-fires burning long past dark, feeding the exhausted workers who had, without needing to be told twice, understood exactly what fifteen days truly meant.
Titanblood had stopped being a village that happened to have walls.
It had become a single, enormous workshop, every hand inside it turned toward the same unspoken purpose.
The Archer Corps
Dean walked the new recruits' ranks each morning with the particular scrutiny of a man who had learned, the hard way, exactly how little raw courage mattered against an enemy that didn't panic.
Two hundred refugees had passed the careful screening Kael had insisted on — desperate people, mostly, fleeing exactly the kind of devastation the west had already visited on four tribes before this one. Very few had ever held a proper weapon in their lives.
Kael found he did not care.
"A sword takes years to master," he told them, standing before the assembled recruits on their first morning of training. "A bow can kill from a wall after months. We don't have years. We have fifteen days to make you dangerous enough to matter, and every day after that to make you dangerous enough to survive."
Every morning began with drawn strings and steady breath. Every afternoon ended the same way, until the muscle memory of release replaced the trembling uncertainty most of them had arrived with. Within a week, the sky above Thornrock had begun to fill each day with the steady, whistling arc of practice arrows, and the walls themselves seemed to take on a different character entirely — no longer simply stone standing watch, but something that had, quite suddenly, learned to bite.
Walls That Bite
Kael oversaw every fresh defensive addition personally, moving from one section of the perimeter to the next with the same restless attention he'd once given every problem the ancient ruins had thrown at him.
Deep trenches opened along the fortress's most exposed approaches, their bottoms lined with the sharpened stakes Lysa's carpenters had spent the week producing, all of it concealed beneath careful layers of brush that would look, to any unwarned eye, like nothing more than ordinary undergrowth. Heavy logs waited at intervals along the steepest slopes, ready to be released down into any advancing formation careless enough to climb within their reach.
And at the wall's widest section, the first of Kael's stone-launching channels stood finished and ready for its first true test.
The release, when it finally came, sent a boulder tearing through the air in a long, brutal arc that struck the distant hillside with a crack loud enough to echo across the entire valley — nearly two hundred meters from the wall, far beyond anything a thrown weapon or even a strong bow could have hoped to reach.
Even Dean, who had watched Kael build strange and useful things all season without much visible surprise, stared at the scorched crater the stone had left behind.
"If fifty of these fire together," he said slowly.
"Their front line disappears," Kael finished, "before they've come close enough to see our faces."
Angelika's Calculations
Angelika arranged her wooden markers across the war table with the same patient precision she brought to every count that mattered, the valley's narrow terrain sketched carefully beneath them.
"They outnumber us nearly three to one," she said, sliding one cluster of markers forward. "Fifteen hundred trained warriors against everything we can currently field, even counting Ironjaw's strength and Windclaw's riders both."
Then she moved a second marker, narrower and more deliberate, into the pass leading toward Thornrock's gate.
"But they can't attack all at once. The valley narrows here, and here again, before it ever reaches our walls. However large their army becomes, only a limited number of soldiers can advance through that ground together at any one time."
"Our walls remove their greatest advantage," Kael said, studying the arrangement.
"Exactly," Angelika said. "If they want this fortress, they'll pay for every single step of ground between the valley's mouth and our gate. Numbers stop mattering the moment they can't bring more than a fraction of those numbers to bear at once."
Kael nodded slowly, the shape of the coming battle finally settling into something he could plan around rather than simply dread.
A Visitor from Ironjaw
Borr returned three days later, and this time, no warband rode at his back.
Instead, wagons rolled down from the northern pass in a slow, deliberate line — iron ore stacked heavy against splintering wood, timber cut and bundled, tanned leather rolled in careful bundles, and sacks of preserved food that Lysa's grain-stretched stores would clearly welcome without complaint.
Dean watched the wagons roll through the gate with an expression that mixed surprise with something close to reluctant respect. "I never thought I'd see Ironjaw supplying us instead of testing our walls."
Borr's gaze drifted toward the western mountains, his weathered face carrying none of its usual hard edges. "If Thornrock falls," he said quietly, "Ironjaw is next. There is no version of this war where my people survive by watching yours fall first."
"That's not the same as friendship," Kael observed.
"No," Borr agreed, his voice as flat and cold as it had always been. "I'm protecting my own tribe. Nothing more sentimental than that."
Kael allowed himself the faintest smile. "The reason doesn't matter, Borr. The supplies do."
Smoke Without End
The Windclaw riders returned that evening carrying news that settled over the war hall with considerably more weight than the day's earlier progress had earned.
"The smoke," one of them said, still catching her breath from the hard ride. "The entire western horizon is black now. Not columns anymore. A wall of it, stretching further than we could ride in a single day."
"No villages remain," another added quietly. "Nothing between us and wherever their fortress now stands. Every settlement that once slowed their advance is gone."
Silence spread through the hall. Harlan closed his eyes slowly, the particular grief of a man who had already lost his own homeland settling fresh across his weathered features.
"They've reached the Empty Plains," he said.
Everyone gathered understood, immediately and without needing further explanation, exactly what those words meant. There was nothing left standing between the western army and Thornrock's walls. No tribe left to slow them. No settlement left to absorb another day of their advance.
Nothing at all.
Except Titanblood.
The Final Report
Just before midnight, Dane entered the war room carrying a sealed report, his expression carrying none of the earlier urgency that had marked every previous message this season. This time, something quieter and considerably heavier had settled over him instead.
He placed the report before Kael without a word.
"No rumors this time," he said. "Our scouts confirmed everything themselves. Firsthand."
Kael broke the seal slowly, and read the single sentence written within.
The western army has crossed the Empty Plains. Estimated arrival: fifteen days.
The hall fell into absolute silence, no one willing to be the first to speak against the weight of that single line.
Fifteen days.
That was all the time Titanblood had left to finish becoming something more than a growing tribe that had survived one lucky season — to finish becoming a fortress capable of standing against the largest war these mountains had witnessed since the ancient empire itself had fallen beneath something no wall, however tall, had ever managed to stop.
