The first thing Logan understood was that the sound wasn't natural.
It wasn't thunder.It wasn't wind.
It was mechanical.
A grinding roar tore down through the trunk of the ancient tree, vibrating the underground chamber with bone-deep force. The braided roots overhead tightened like muscle under strain. Splinters rained down in fine, sharp bursts.
"They've brought equipment," Logan said through clenched teeth.
Above them, metal bit into living wood again.
The impact rang like a scream.
Juno didn't flinch.
But the green light inside her eyes brightened.
"They're cutting through the outer ring," she said quietly. "They can't see what's beneath."
"Yet."
The chamber shook violently. A deep fracture split along one side of the root dome. A blade long, steel, industrial punched through, carving a jagged line across the ceiling before retracting.
Logan felt rage flood his chest.
Not just his own.
The forest's.
It surged through him like heat.
"They're killing it," he muttered.
"They're trying," Juno corrected. Her voice layered again with that deeper resonance. "It won't die quietly."
The roots around them began to move.
Not randomly.
Strategically.
Thick cables of living wood shifted, weaving tighter across the chamber walls. The central trunk trembled again as something heavy crashed against it from above.
A second breach split open overhead.
This time, light poured through.
Harsh white beams stabbed downward, cutting through spores and green glow alike.
Logan shielded his eyes.
Silhouettes appeared at the opening.
Helmets.
Shields.
Weapons.
Not loggers.
Tactical.
"They found it on purpose," he breathed.
Juno's fingers tightened around his.
"Yes."
A metallic object dropped through the opening, hitting the chamber floor with a hard thud. It bounced once.
Rolled.
Stopped between them.
Logan recognized it instantly.
Gas canister.
"Down!" he shouted.
He tackled Juno as the canister ruptured with a violent hiss. Thick gray smoke flooded the chamber in seconds, heavier than air, sinking fast.
The forest reacted.
Roots snapped downward from the ceiling, smashing the opening shut, but more canisters followed three, four clanging against wood and stone.
The chamber filled with chemical haze.
Logan coughed, pulling his shirt over his mouth.
Juno didn't cough.
She inhaled sharply instead, and the green light beneath her skin pulsed brighter.
"The toxins," she whispered. "They're meant to weaken it."
"Can you fight it?" he demanded.
Her gaze lifted upward toward the fractured dome.
"Yes."
The roots beneath their feet surged.
Logan barely had time to brace himself before the ground shifted violently, lifting them both as a thick platform of woven roots rose from the chamber floor.
Above, the breach exploded inward as armed figures dropped through the opening.
They hit the ground hard but not clumsily.
Disciplined.
Organized.
Masks sealed.
Thermal optics glowing faintly red in the dim green light.
"Targets confirmed," one voice crackled through a comm unit.
Logan's blood ran cold.
"They're not here for lumber," he said.
"They're here for integration subjects."
Juno's eyes snapped toward him.
"Subjects?"
A spotlight locked onto her face.
"Visual match," another voice reported. "Secondary confirmed."
Logan stepped in front of her instinctively.
The first shot wasn't a bullet.
It was a dart.
It struck his shoulder with a sharp sting.
He ripped it out instantly, but warmth spread fast through his bloodstream.
Sedative.
The forest felt it too.
Rage exploded outward.
Roots burst from the chamber floor like spears, slamming into armored figures and throwing them back. One soldier fired upward into the ceiling, but the rounds ricocheted uselessly against living wood.
"Contain the girl!" someone shouted.
Two figures advanced through the smoke, moving fast, coordinated.
Logan lunged forward, tackling one before he could reach Juno. They hit the ground hard. The soldier's visor cracked against stone. Logan drove his elbow into the man's throat before ripping the weapon from his grip.
More darts fired.
One struck his thigh.
His vision blurred.
The forest surged through him again, countering the drug with raw adrenaline and something deeper something ancient and furious.
Juno stepped forward.
And the chamber answered her.
The green light flared blindingly bright.
The braided root column in the center of the chamber unwound violently, snapping outward in thick coils that wrapped around two advancing soldiers mid-stride. Armor groaned under crushing pressure.
Juno lifted her hand.
The roots obeyed.
Logan stared.
"You're controlling it," he said hoarsely.
"I'm helping it," she corrected.
Another breach split open above.
More figures dropped through.
Too many.
"They'll burn it," Logan said. "If they can't cut it, they'll burn it."
Juno's gaze flickered with something like fear.
"If they ignite the chamber"
The thought didn't need finishing.
The forest might survive axes.
It would not survive sustained fire beneath its heart.
Logan forced himself upright despite the sedative clawing through his veins.
"Then we don't let them," he said.
He grabbed a fallen rifle and fired not to kill, but to force them back from their positions. The shots echoed violently through the chamber.
One of the soldiers raised a launcher.
Logan's eyes widened.
"Juno!"
Too late.
The projectile fired.
It wasn't explosive.
It was incendiary.
The round struck the root wall and erupted in bright orange flame.
The chamber screamed.
Not metaphorically.
The sound ripped through Logan's skull a deafening, layered howl of something ancient in agony.
Flames licked along resin-rich bark.
The green light flickered erratically.
Juno cried out, dropping to one knee as if struck physically.
"They're burning the network," she gasped.
Logan grabbed her shoulders.
"Can you stop it?"
"Yes but not alone."
Another incendiary round hit.
Fire spread faster this time.
Smoke thickened.
The soldiers advanced behind shields.
Logan made a decision in that split second.
"You said it wants me," he said.
Juno's glowing eyes locked onto his.
"Yes."
"Then let it."
Her expression changed instantly.
Fear.
"Logan, no"
"Do it."
The flames climbed higher.
The chamber trembled violently as more roots collapsed inward.
Logan stepped into the center of the chamber and pressed his palm against the exposed trunk.
The wood was hot.
Burning.
"Take it," he said through clenched teeth.
The forest did not hesitate.
Pain exploded through him.
Not burning expansion.
His senses shattered outward. The chamber dissolved into a web of light and root and vibration. He felt every flame licking at bark. Every blade cutting above ground. Every footstep of every intruder.
And he pushed back.
The roots surged with renewed force, slamming upward through breaches and wrapping around equipment above. Metal screamed as machinery was ripped sideways. Outside, something massive crashed to the forest floor.
Below, the soldiers faltered as the ground shifted violently beneath them.
Juno rose to her feet, green light blazing fully now.
Together, they moved.
Not speaking.
Not planning.
The forest flowed through both of them.
Flames extinguished as roots smothered oxygen.
Weapons were torn from hands.
The chamber sealed itself around the intruders like a closing fist.
Within seconds
Silence.
The fire died completely.
Smoke thinned.
The green light steadied.
Logan collapsed to one knee, breath ragged.
The connection loosened but did not disappear.
Juno stepped toward him slowly.
"You crossed," she whispered.
He looked at his hands.
Faint green veins pulsed beneath his skin.
"Not all the way," he said.
Above them, the trunk remained scarred but intact.
The immediate threat was gone.
But Logan could still feel it
Beyond the basin.
More engines.
More footsteps.
This had not been a lone team.
This was only the beginning.
And now
They knew exactly what lived beneath Black Hollow.
