The tunnel ahead began to change. The air shifted—cooler now, slightly damp. The suffocating stench of rust and mildew gave way to something almost natural. Not clean, but… older. Fungal. Earthy. The texture of the walls grew more uneven, less concrete, more rock. Echoes bounced off the stone like whispers.
Then came the sound.
Faint at first. A soft trickle. Then a low, rolling murmur—water.
Cass paused, one hand raised.
Wang crept up beside her, crouching low. His voice barely a whisper. "That a stream?"
Cass nodded slowly. "Sounds like it."
They moved forward cautiously, step by step, until the tunnel finally opened into a vast underground chamber. The walls spread wide in all directions, a jagged cavern filled with shadow. Their flashlights flicked left and right, catching glints of mineral deposits and clusters of slick moss growing on damp stone.
But what drew their eyes was the lake.
A wide, black body of water stretched before them. Still. Perfectly still. Too still.
The source of the sound—a narrow stream—emptied into one side of it from above, trickling down over layers of rock like a leaking faucet. Ripples spread slowly across the surface. But something about it was off. The water was too dark. Not like freshwater. More like… oil mixed with blood.
"What the hell is this place?" Wang murmured.
Cass scanned the chamber. "Some old water catchment? Maybe runoff from the mine?"
Then she saw it.
"Look," she said, pointing.
A rectangular glow shone from the cavern wall about a hundred feet ahead, high up—easily thirty feet above the cave floor. A metal trap door had been propped open, a dull yellow light pouring out like a spotlight in the gloom. Just beneath it, something clanged—a metal tray or bin being emptied.
From above, a cascade of garbage tumbled down.
Food scraps. Bones. Grease. A whole bucket's worth of waste fell from the trap door, splattering across the cave wall before tumbling into the lake with a series of wet plops.
And then… the water moved.
It wasn't subtle.
The entire lake surged, like something massive had just shifted beneath the surface.
A second later, the garbage disappeared—all of it—dragged under with shocking speed. The chunks of meat, bone, and food didn't bob or float. They sank like they were yanked by an invisible drain.
Or teeth.
Wang took an involuntary step back. "The fuck was that?"
Cass stared at the water, face unreadable. "That's no ordinary lake."
"You don't say," Wang muttered. "You saw that, right? It ate the garbage."
Cass crouched near the edge, eyes locked on the rippling surface. "Ten seconds. Maybe less. Whatever's in there, it's fast. Efficient."
"Efficient," Wang repeated, baffled. "That's how you describe that thing? Like it's a goddamn Roomba?"
Cass shrugged, still staring. "Could be Red's pet. Or a leftover from before the mine collapsed. Maybe some bio-waste experiment they flushed and forgot."
Wang rubbed his face. "Great. Mutants and now some sewer lake meat-grinder monster. What's next, flying spiders?"
Cass's flashlight beam arced upward toward the trap door. "That hatch. That's gotta be our way in. But there's no ladder. No rope."
Then she spotted it.
To the left of the cavern wall, mostly hidden behind some moss and jagged stone, was a narrow path of natural rock formations—worn and slippery, tilted steeply upward toward the hatch. Almost like steps, if steps had been made by a drunken god with no regard for physics.
"Shit," she muttered. "Those rocks. They might lead up."
Wang followed her gaze, then frowned. "You serious?"
The "steps" were barely wide enough for a boot. Some jutted outward at weird angles. Others looked ready to crumble under a strong breeze. It was more of a vertical obstacle course than anything resembling a path.
"Not a lotta options," Cass said, standing.
"What if we fall?" Wang asked.
Cass pointed to the lake. "Then we get eaten by whatever the fuck lives in there. So, don't fall."
Wang sighed, staring up at the rocky incline. "God, I miss elevators."
She smirked. "Get your ass ready. We'll wait five minutes. Let the last feeding cool off. Then we climb."
Wang walked a few steps closer to the water, cautiously kneeling down. The lake had gone still again. Totally flat, like glass. No ripples. No bubbles. Just the faint glimmer of refuse residue floating on the surface.
"I don't like it," he said softly.
"You're not supposed to," Cass replied behind him. "Fear keeps you alive."
He turned back toward her. "You really think Red's crew dumps food waste in here regularly?"
"Yeah," she said. "Which means they think this thing's on their side."
Wang stood, brushing grit off his pants. "I'm starting to think Red Beard doesn't want visitors."
Cass cracked her neck. "Then he's about to be real disappointed."
They both stared up at the flickering light above the hatch, and the hellish climb that awaited.
Q: Are you good at rock climbing?
