The vibrant green labyrinth of the delta ended abruptly, severed as if by a butcher's cleaver.
The humidity dropped instantly, replaced by a dry, salty heat that cracked the lips and stung the eyes.
Behind them lay the breathing, buzzing world of the Land of Rivers. Ahead lay Katabami—a wasteland of grey mud and silence.
Kakashi Hatake stood on the ridge of the last dyke, his vest flapping in the hot, chemical wind. He looked down at the "Gold Mine."
It wasn't a mine. It was a wound.
Miles of grey mudflats stretched out before them, punctuated by the jagged, rot-blackened stumps of ancient mangrove trees.
They looked like broken teeth sticking out of the mud—tombstones for a forest that had been hacked down to feed the sluices.
The river didn't flow here; it stagnated in square, man-made pools, choked with the yellow foam of refining agents.
The water didn't ripple; it sat heavy and oily, reflecting the grey sky like a dirty mirror.
"It smells like rotten eggs," Tenten murmured, covering her nose and mouth with her hand. "And... bleach?"
"Sulfur and mercury," Kakashi corrected, his eye tracking the movement of the workers in the pits below. "Standard extraction chemicals. They've killed everything."
He looked at the ground. The mud was cracked and white-streaked with salt.
Without the tree canopy to regulate the humidity, the water had turned hypersaline.
The glare off the salt crust was blinding, harsh and unforgiving compared to the soft, filtered light of the mangroves.
The salt crystals crunched under their boots—scritch-crunch—like walking on broken glass.
"Movement," Neji whispered, his Byakugan active.
"Central structure. Stone. Fortified."
He pointed to a large, grim building sitting on the highest point of the dykes, overlooking the misery below like a prison warden's tower.
Black banners fluttered from the watchtowers, snapping in the silence.
The fabric of the banners was heavy and wet, making a dull thwup-thwup sound instead of a sharp crack.
"That's Raiga's command post," Kakashi deduced. "And judging by the layout... he's expecting company."
From the tower, a bell tolled once—a low, discordant note that vibrated through the dense air.
"Let's go say hello," Sasuke said, stepping off the ridge.
They descended into the mine.
The silence was absolute.
In the delta, the air was alive with insects and birds. Here, the chemicals had killed the fish, the crabs, and the mosquitoes. The only sound was the mechanical clanking of dredging tools and the suck-pop of boots pulling free from the heavy, grey clay.
SQUELCH-POP.
The mud didn't just grip; it sucked, pulling with a vacuum pressure that made every step a battle against the earth.
Workers—emaciated, sun-burned men and women—paused to watch them pass.
They didn't speak. They didn't ask for help.
They just watched with hollow, terrified eyes.
Their skin was stained yellow from the sulfur, peeling in patches like old paint.
"Halt!"
A figure stepped out from behind a pile of lumber.
He was young, skinny, and shaking.
He wore a mismatched set of worker's clothes that were too big for him, and he held a spear that wobbled in his grip.
The spear shaft rattled against his oversized belt buckle—clack-clack-clack—betraying his shaking hands.
Karashi. Sanshō's son.
"You..." Karashi stammered, looking at the Konoha headbands.
"You're Leaf Ninja. You can't be here! This is... this is private property!"
"We're looking for Raiga Kurosuki," Kakashi said calmly, stepping forward.
"And a missing person report."
"Nobody is missing!" Karashi squeaked, backing up.
"We're all... happy here! We're a family! Raiga-sama protects us!"
Behind Karashi, a shadow moved.
A man stepped out of the stone mansion.
He was tall, draped in a grey hooded mantle. Waist-length green hair spilled out from under the hood, framing a face that was handsome but deeply, unsettlingly sad. Bandages covered his neck and arms.
Raiga Kurosuki.
On his back, strapped in a nest-like carrier, was a small bundle. A child with purple hair and red eyes peered out.
Ranmaru.
Kakashi froze.
The image hit him like a physical blow. The rogue swordsman.
The delicate, androgenous child protector.
The bond that radiated between them—not master and servant, but two halves of a whole.
Zabuza and Haku, Kakashi thought, a phantom pain throbbing in his sharingan eye.
It's the same pattern.
Raiga looked down at them. His blue eyes were filled with tears.
"Visitors," Raiga wept softly.
"Are you here for a funeral? We have so many graves to dig today."
"Raiga-sama!" Karashi jumped in, waving his hands frantically.
"I'll handle them! They're just... lost! I'll tell them to go away! You don't need to—"
"Karashi," Raiga interrupted, his voice thick with emotion.
"You are such a coward. It is tragic."
He wiped a tear from his cheek.
"Speak to them," Raiga ordered, turning his back.
"Tell them to leave. Or tell them to pick a plot in the garden. I do not care."
He walked back into the mansion, the child on his back glowing faintly red.
A smell of ozone and rain drifted from the child, cutting through the chemical stench—a clean scent in a dirty world.
Karashi spun around, sweating profusely.
"You heard him!" Karashi hissed, trying to look tough.
"Go away! Before he buries you! He... he loves funerals! He cries for everyone he kills! It's super creepy!"
Sweat dripped from Karashi's nose, sizzling faintly as it hit a hot stone—tsss.
Kakashi looked at the terrified boy. He looked at the mansion.
"We aren't leaving," Kakashi said.
"But we'll look around. Sasuke, Neji, check the perimeter. Tenten, stay with me."
Sasuke walked away from the main group, heading toward the western edge of the mine.
He hated this place. It smelled of weakness.
The mud sucked at his boots with a greedy, wet sound, trying to pull him down into the filth.
The tunnel walls wept condensation, slick and cold, smelling of trapped gases and old rust.
Hiss. Throb.
His hand flew to his neck.
The Curse Mark.
It wasn't burning. It was... buzzing.
It felt like a compass needle spinning near a magnet. It pulled him toward a tunnel entrance cut into the side of a dyke.
Something is down there, Sasuke thought, his eyes narrowing. Something compatible.
He walked into the tunnel.
It was cooler inside, but the smell was worse—stagnant water and fear.
The air here was still and dead, amplifying the sound of his own breathing until it sounded like a roar.
A man was working in the gloom, swinging a pickaxe against the wall.
He was shirtless, his skin covered in sores from the chemical exposure. The sores wept a clear fluid that mixed with the grime on his skin, glistening in the low light. His ribs counted themselves against his skin.
Tsurai.
"Hey," Sasuke said.
The man jumped, dropping the pickaxe. He spun around, his eyes wide and bloodshot.
"Don't sneak up on me!" Tsurai gasped, clutching his chest. "I thought you were... him."
"Him?" Sasuke asked, stepping closer.
The Curse Mark itched harder.
"The shadow," Tsurai whispered, looking past Sasuke into the dark. "Don't travel alone in the tunnels, kid. Something watches. I feel it."
He rubbed his arms, shivering.
"I hear hissing," Tsurai said, his voice trembling. "Deeper in the caves. Like a snake. But... bigger. And sometimes... sometimes the shadows move when there's no light."
Slither.
A faint, dry rasping sound echoed from deep in the rock, too rhythmic to be water.
"Hissing," Sasuke repeated.
He looked down the tunnel. The darkness seemed to stretch forever.
"You're hallucinating," Sasuke dismissed, turning away. "It's the fumes. Go get some water."
"It's not fumes!" Tsurai pleaded, grabbing Sasuke's arm. His grip was weak, his hand clammy. "Help me... please... it's agony..."
Help me, Tsurai. Help me, Agony.
Sasuke pulled his arm free. He looked at the man with cold indifference.
"I'm not here to help you," Sasuke said. "I'm here for the source."
He walked back out into the blinding salt glare, leaving Tsurai in the dark.
But as he walked, Sasuke touched his neck again.
The mark was quiet now. But he knew what he had felt.
Snake, Sasuke thought. Orochimaru isn't here. But something is..
He looked up at the mansion where Raiga and the red-eyed child waited.
The Curse Mark gave a sharp, hot throb—thump—syncing perfectly with the distant beat of a drum starting up in the mansion.
