Strangle vines lifted soldiers out of formation and crushed their armor, dropping the mangled remains into the churned earth. Wet thuds. Small pops of satisfaction rippling through the Rootmind. One kill bled into the next until the deaths blurred into something constant — static from a broken speaker nobody could turn off.
Three hours into the combined defense, the empire's mages had stopped wasting fire on the outer kill zones. They'd figured out the range. Pairs working in rotation — one casting a barrier of cold air while the other hurled concentrated fire at the vine clusters. Cold flash-froze the sap. Fire shattered what remained. An entire section of northeast vines went from a writhing carpet of green to blackened, curling husks in under a minute.
He pushed nutrients toward the scorched earth through the Rootmind, directing the surviving vines to spread runners into the ash.
They sprouted. Three inches of new growth before the next volley turned them to cinders.
Waste of energy. He kept doing it anyway. Stopping meant surrender, and his body wouldn't allow it — palms flat against the Ent bark, fingers digging into the wood grain, jaw locked hard enough that his teeth ached.
The centaur cavalry was still hitting and running, but the empire had caught on. Shield walls formed on the flanks — overlapping ranks with shields locked together, iron and oak to any charge. The first squad that hit one of these walls learned the hard way. Impact through the ground: a thousand-pound body hitting a reinforced line at full gallop, bone cracking, hooves losing traction on blood-slicked earth. Three centaurs went down. Two got back up. One didn't.
The centaur elder was shouting from the southern screen in a language that meant nothing to Chris. The riders adjusted — harrying the edges instead of charging head-on, darting in at the corners where the formation thinned, pulling back before the soldiers could turn. Less devastating. More sustainable.
A rat ran across the top of the northern wall, stopped between Chris's knees, and sat there grooming its whiskers for three full seconds before a burst of mage fire somewhere to the east startled it into the smoke. A rat, cleaning itself, in the middle of a siege. It lodged in his exhausted brain and wouldn't let go.
The Ent cracked.
Sera was on the northern wall when it happened.
Sound first — a deep, splintering groan that traveled through the Rootmind like a fracture spreading through ice. Bark split outward in a shower of splinters. A gap opened in the living wall. Eight feet wide, maybe. Enough for soldiers to pour through if they were fast enough.
"Gap! Northern wall, center section!" She was already moving, sliding down from the rampart into the smoke with a half-dozen defenders on her heels.
Pressure of bodies in the breach. Vibrations of combat. Sera's footfalls came through the Rootmind — fast, controlled. She wasn't trying to close the gap. She was buying time for something else to fill it.
Thorn vines closest to the breach surged forward, wrapping around the shattered bark, trying to bridge the gap with a lattice of thorned runners. Ugly work. Wouldn't hold against a determined push. Thirty seconds. Maybe a minute.
Korr was everywhere.
His voice had gone from hoarse to raw to something barely recognizable — a croaking bark that carried further than it should, snapping orders at defenders who couldn't see him through the smoke. "Second rank, hold the angle — Mira, pull your people back from the eastern breach, it's not worth the bodies — Denna, stop throwing those damn things and save them, we're going to need them later —"
Mira emerged from the eastern fog. Defenders trailing behind. Some limping. One being carried between two others, his head lolling at an angle heads don't loll at. Her face had that unreadable set.
"How many?" Korr demanded as she reached the inner wall.
"Four down. Eight wounded bad enough they can't fight." She wiped blood from her jaw — a reflex, like brushing away sweat. "The bamboo there is gone. Mages burned a path straight through. They'll be at the wall in ten minutes if they push."
"They'll push."
Mira nodded. Neither of them said anything else.
The rat came back. Opposite direction this time. Faster. Didn't stop.
Then the empire committed their second wave.
A new rhythm of boots behind the main battle line — faster, fresher than the exhausted troops they'd been grinding against for hours. Reserves. Imperial commanders had been holding them back. Now they poured around the flanks of the spent front line, formations tight, shields clean, footsteps landing with the easy confidence of men who hadn't spent the last six hours watching their friends die in thorn patches.
Chris's nails dug deeper into the Ent bark.
Hundreds. Pushing into the gaps the centaurs had carved. Filling the spaces where the outer defenses had been destroyed. The bamboo groves triggered and killed, but the soldiers behind the dead ones stepped over the bodies and kept coming. Cattail patches grabbed ankles and held, but the soldiers behind the trapped ones cut the stalks down and kept coming. Everything the defenses threw at them absorbed, processed, discarded. An assault force with enough depth to treat casualties as overhead.
The inner kill zones were still working — deaths still rippling through the Rootmind — but the weight was too much. Every plant that killed a soldier drew mage fire from the fresh casters behind the advance. Cycling through in rotations, maintaining a rate of fire the defenders couldn't match. Ghost plants flared until their glow guttered and died. Thorn vine patches thickened and then burned. Scream flowers shrieked until their voices cracked and went silent.
Somewhere behind the main Imperial line, a younger female centaur had started about an hour ago. Dark-haired, lean, with symbols painted on her equine flanks in a red pigment that smelled like iron oxide. She wasn't fighting. Pressing her hands into the soil around the base of the Ent wall, humming in a low, resonant tone that cut through the chaos. The plants nearest to her responded — not dramatically, not the way they did when Chris pushed a command, but subtly. Growth quickening. Connections strengthening. Dying sections clinging to life a few seconds longer than they should have.
Nature magic. Centaur shamanic tradition, maybe. Something older. Whatever it was, it resonated with the Rootmind — the signal clearing, the static fading, like a radio finding its frequency.
The shaman found him on the wall. She'd climbed the Ent-root steps on all fours, hooves finding each one without hesitation.
"You're burning out." Quieter than the elder's voice. Softer. An accent from somewhere far from the Barrens.
He didn't look up. "Noticed that, did you."
"The green feels thinner where you touch it." She crouched beside him, her human torso folding forward, and pressed a hand against the bark near his. "I can ease some of the strain. Not replace what you're losing. Just smooth the edges."
A gentle current moved through the Rootmind — softening the jagged edges where plants had died, filling in the gaps with something steady and cool. Not much. Enough that Chris could think clearly for the first time in what might have been hours.
"They're going to commit their heavies soon." Her eyes stayed on the Imperial lines. "The ones with the glowing weapons. Handlers have been pulling them forward."
Through gaps in the smoke, shapes moving behind the main battle line. Taller. Heavier. Armor catching the firelight in ways normal steel shouldn't. Handlers clustered around them, postures tight and controlled.
"They're called heroes." He spat the word into the smoke. "Bad name for them. Summoned by the holy empire. Dropped into whatever war they're told to fight."
The shaman's expression didn't change. "They don't fight like soldiers. They fight like things that have been told they cannot lose."
Horns. Different from the advance signal — longer, lower, a sustained note that vibrated in his ribs. Siege engines. The creak of wheels on dead earth, axles grinding under too much weight. The ground's vibrations changed character through the Rootmind. Heavier. More rhythmic. Machines built to break things.
The heroes began to move. Walking forward through the smoke in a loose group. The whole Imperial line adjusted — soldiers pulling back, mages redirecting fire, the formation reorienting itself around these figures like iron filings around a magnet. Handlers stopped at a line maybe a hundred yards from the wall. Let the heroes keep walking. Whatever controlled those things had decided the leash was long enough.
"Here they come." Korr stood at the wall's edge, sword drawn, his voice barely above a whisper — ruined, raw. The demon's red eyes tracked the heroes' advance. "About time. I was starting to think they didn't want to play."
The heroes picked their way through the remnants of the outer defenses. Stepping over burned cactus. Pushing through tattered thorn vine mats. Weapons caught the light and threw it back in bright, clean slices.
Through the Rootmind, they didn't exist.
Gaps. Absences. Blank spaces in the network where nothing reached.
The screaming started again. Human this time, not flowers.
The night swallowed it whole.
