A vibration climbed through the soles of Chris's boots — something deeper than marching feet or mage fire, starting below bedrock and moving up through his skeleton. His hands were still in the dirt at the base of the world tree, fingers curled into soil that was cold and slick, streaked with fluids he had no name for. The Rootmind pulsed against his palms, different from the frantic combat throb. Recognition.
The ancient Ent moved.
Chris had understood on some level that the old tree-spirit was aware. The bark warming beneath his touch. The way it shifted its root-anchors to brace the wall. It had been rooted here longer than the village, longer than the Barrens being dead, longer than whichever empire had first stuck a flag in this soil. Patient. Now, for the first time since Chris had connected to it through the Rootmind, it chose to act.
Uprooting was not fast. The sound came first — a grinding groan of wood fused to bedrock for centuries being torn free. Cascades of soil poured from the Ent's base. The wall shuddered as root masses the size of drainpipes pulled out of the earth, leaving a gap in the northern perimeter that Korr was going to have opinions about.
The Ent rose, trunk wide enough to shelter a family of six beneath its canopy, swaying as it found balance on legs that hadn't borne weight in Chris's lifetime. Branches interwoven with thorn vines and ghost plants spread wide, scattering defenders and dead growth alike. A dead crow tumbled from the crown, wings stiff, hitting the ground with a sound like a dropped glove. The fighting to the north went quiet as soldiers on both sides looked up at the thing that had just decided to get up and walk.
It turned east, toward the cliffs and the entity pulling itself free.
Chris pressed harder into the soil, trying to read the Ent's intent through the Rootmind. What came back was older than language. The entity was an offense against the shape of the world, and the Ent had known it since before the dungeon rotted, since before the land died. Had been waiting. Now it was going to do something about it.
The first step knocked Chris sideways. His shoulder cracked against the world tree's trunk. He caught himself, gagging, vision swimming with bright spots. The Ent's foot came down between the inner wall and the eastern approach, a mass of root and bark and heartwood old enough to predate any flag — the impact sent shockwaves through the Rootmind that made every connected plant flinch. Another step followed. Then another. Slow. Thunderous.
The smaller Ents followed.
Seven of the wall Ents peeled away from the northern and eastern defenses, roots tearing free with protests the Rootmind relayed as a cross between pain and stubbornness. Saplings by Ent standards, barely a century old, trunks slender compared to the ancient one's girth. They uprooted and fell into line behind their elder anyway.
"Chris." Korr was at his elbow, red eyes tracking the march east. His voice had been ground to gravel. "What the hell is happening?"
"They're going after it."
"Going after what? The—" Korr's gaze swung east toward the dark mass pulling itself free from the cliffs. His jaw set. "They're going to fight that thing?"
"I don't think they're going to fight it." Chris pulled his hands free and stood, one hand braced against the world tree. "I think they're going to slow it down."
"Slow it down." The muscle beneath Korr's jaw jumped. "With what, exactly? Good intentions?"
The Ents crashed into the entity's outer tendrils before he could answer.
The ancient Ent reached the leading edge of the black-green growth and began tearing — massive branches sweeping down through the thorned runners, ripping, pulling, snapping. Smaller Ents flanked the main body, each grabbing fistfuls of tendrils and pulling in opposite directions. Splinters of black growth sprayed across the churned earth.
The entity answered. Tendrils reversed course, curling around the Ents' trunks, climbing, constricting. One of the smaller Ents shrieked through the Rootmind as a cluster of thorned runners wrapped its base and began squeezing. Bark split. Sap ran black, steaming where it hit the ground. The Ent twisted free. The ancient one reached over and tore the tendrils away with a single branch-sweep that sent a shockwave rippling through the soil.
Too many tendrils. Too much mass. Too deep in the cliff stone. The growth the Ents destroyed pushed back through the broken remains in seconds, new black-green runners replacing what had been ripped away. They were buying time, the same way every defender in this battle had been buying time all night. Chris didn't know what the time was for.
Through the thinning smoke, officers clustered on the northern horizon. Some pointed east at the entity. Others jabbed fingers toward the village. Nobody had briefed the Imperial formation on what to do when an ancient horror crawled out of the cliffs behind their target and started fighting the trees.
Korr made the call without asking.
"Northern wall is too weak to hold if they push now." He was already moving, his ruined voice carrying to the nearest defenders through sheer lung power. "But they won't push. Look at them — they're arguing. We pull back from the north and reinforce the east. Mira!"
Mira materialized from the smoke, her face a controlled mask over exhaustion. "What do you need?"
"Everyone who can hold a weapon on the eastern approach. Between the Ents and the village. If those tendrils break through, we're the last thing between the entity and everyone we're trying to protect."
She nodded and vanished, shouting names as she moved through the defensive positions, pulling fighters from the northern wall and redirecting them east. Some of them were barely upright — blood-soaked, ash-grey, running on spite and whatever reserves a body dredges up when it has nothing left. They went where Mira pointed.
The centaur shaman was at Chris's side before he noticed her, which was unsettling given that she was the size of a warhorse. Her dark hair was plastered to her skull with sweat and the symbols painted on her flanks had smeared into shapelessness. Her eyes were clear.
"Your network is dying," she said. "Not fast, but steadily. Without the whisper-thing to process the signals, your mind is doing the work of something far larger."
"I know."
"You don't." She crouched, her human torso folding forward, and pressed both palms into the earth. The same low resonant hum from the battle filled the air. The Rootmind shifted — cleaner, sharper, the static thinning. "I can amplify what's left. Bridge some of the gaps. But I can't replace what you lost."
"Then why are you helping?"
She looked at him.
"Because that thing in the cliffs has been eating the land for longer than my herd has been alive. When it finishes with you, it'll move to the grasslands. After the grasslands, the forests." She stopped. One hand rose and fell — a shrug that looked almost human on a creature that was mostly horse. "You see the pattern."
She pressed deeper into the earth. The Rootmind sharpened enough to track the Ents' battle with the entity, enough to read the imperial forces regrouping north, enough to monitor the thorn vine patches on the eastern approach, their growth stunted but their thorns still needle-sharp.
Chris reached toward the eastern edge of the network.
The entity reached back.
The contact hit like brushing against something vast and cold at the bottom of a dry well. Not a thought — the entity didn't think. Just hunger. Directionless, patient, accumulated over years in the dungeon's depths, consuming everything that fell into it. Chris was there, and the entity's awareness found him through the Rootmind — a warmth in a cold place. It was reaching for him. Not the village. Not the Ents.
The shaman yanked her hands from the earth and staggered, catching herself on one foreleg.
"It's coming for you. Through the ground, through the roots — it's probing the network's edges. Testing for a way in."
The Ents had been driven back fifty yards. Two smaller ones dragged themselves clear, trunks cracked, sap weeping. The ancient one still stood, still tore at the tendrils, but each branch-sweep came slower than the last.
Mira's fighters filed into position between the Ents and the village. A ragged line of battered defenders holding weapons taken from dead soldiers, standing in the path of something older than any of them. Mira at the center, sword drawn. The entity's tendrils crept closer through the black-green runners carpeting the ground between the Ents and the defenders, inching forward.
It wants me. Not the village. Not the plants. Me.
Through the thin, ragged pulse of the Rootmind, Chris traced the entity's probing touches at the edges of the network.
Korr stood beside him.
"We need a plan."
"Yeah." Chris stared east at the dark shape pulling itself free from the cliffs, at the Ents being driven back, at the tendrils crawling toward Mira's line. "I'm working on it."
The horns blew from the north.
The empire had stopped arguing.
