Chapter Text
The storm had rolled in faster than Monarch anticipated.
The sky above the jagged cliffs was a bruised, heavy purple, and the freezing wind whipped salt spray directly into their eyes. Monarch gritted their teeth, struggling to tie off the last mooring line on the old wooden dock. The waves were getting violent, crashing against the pylons with a deafening, hollow boom that vibrated right through the soles of their boots.
Just one more knot, and they could go inside to the warmth of the fire.
Monarch yanked the heavy, waterlogged rope tight. As they bent down to secure it, the wind seemed to drop for just a fraction of a second.
In that unnatural pocket of silence, a sound drifted up from the churning black water.
It wasn’t a word. It was a melody, a sharp, piercing, and entirely wrong for the chaos of the storm. It vibrated in Monarch’s skull, a low, thrumming hum that made their vision blur and their limbs suddenly feel like lead.
Monarch blinked hard, stumbling back a step. Their instincts screamed at them to run, but a heavy, terrifying curiosity forced them to look down over the edge of the dock, peering into the dark, churning foam.
Nothing. Just the violent sea.
Monarch exhaled a shaky breath, chalking it up to exhaustion. But as they turned to leave, the water erupted.
It happened too fast to even scream. Something impossibly cold and violently strong clamped around Monarch's ankle. It felt like a vice grip made of ice and sharp, painful ridges.
With a single, effortless yank, the world tilted.
Monarch hit the freezing water with a concussive shock, the air instantly punched from their lungs. Panic flared as the freezing ocean swallowed them whole. They kicked and thrashed, desperately clawing upward toward the fading grey light of the surface, but the grip on their ankle was immovable. It was dragging them down, fast and deep.
Through the stinging saltwater and the rush of bubbles, Monarch finally saw what had them.
It wasn't a shark. It wasn't a riptide.
A face emerged from the murky darkness, hovering just inches away. Dark, unnatural skin gleamed in the dim light. A pair of wide, glowing, predatory eyes locked onto Monarch’s terrified gaze, utterly unblinking. As Monarch let out a muffled, bubbling gasp for air, the creature smiled.
The smile stretched entirely too wide, revealing rows of needle-sharp, translucent teeth.
The siren tilted his head, watching the sheer terror in Monarch's eyes with a look of pure, unadulterated amusement. Then, with a flick of a massive, shadowed tail, he dragged his new prize down into the crushing dark.
-----------------------------
Monarch woke to the sensation of crushing cold and the taste of salt and copper.
Their lungs burned, violently expelling seawater as they rolled onto their side, coughing until their throat was raw. The ground beneath them was merciless, slick, jagged rock that tore at their soaked clothes and scraped their skin. It was pitch black, save for a faint, unnatural bioluminescent glow pulsing beneath the surface of a deep pool just a few feet away.
Every muscle screamed in protest as Monarch forced themselves to their hands and knees. The air was thick, damp, and freezing.
Where am I? The panic was a living thing in their chest. They scrambled backward, their hands sliding on the slime-coated rocks until their spine hit the solid, freezing wall of the cavern. There was no sky. No wind. Just the oppressive, echoing sound of water lapping against stone.
Then, the water in the center of the pool began to churn.
Monarch froze, their breath catching in their throat.
The Siren rose from the surface, completely silent. Water cascaded off his pale shoulders and the dark, iridescent scales dusting his ribs and jawline. He didn't swim to the edge; he glided, predatory and effortless, until his chest was flush with the rocky shoreline. He folded his webbed hands on the stone and rested his chin on them, watching Monarch.
He looked exactly like a cat observing a trapped mouse.
"You're remarkably durable," The Siren mused. His voice echoed off the cavern walls, melodic, layered, and dripping with cold amusement.
Monarch pressed themselves harder against the wall, eyes wide, shivering violently as the freezing air bit through their soaked clothes. "What-... what are you?"
His’s eerie smile returned, those translucent, needle-like teeth glinting in the faint bioluminescent light. He didn't answer. Instead, he reached a hand out, his long, clawed fingers tapping a slow, agonizing rhythm against the wet stone.
"Stand up," he commanded.
It wasn't a request. The words carried a subtle, thrumming vibration that dug directly into Monarch's brain. Monarch's body betrayed them, muscles twitching and forcing them to their shaky feet against their own will.
His’s eyes tracked the violent, uncontrollable tremors racking Monarch's body. He seemed fascinated by the frailty of it.
"Run," he whispered, his glowing eyes flashing with cruel excitement.
Monarch didn't need to be told twice. The compulsion broke, and pure adrenaline took over. They bolted, slipping and stumbling over the jagged rocks, heading blindly into the deeper, darker recesses of the cave.
Behind them, a low, melodic laugh echoed off the stone walls, followed by the terrifying sound of something massive and wet sliding out of the water.
The game had officially begun.
Monarch's boots slipped on the algae-coated stone, sending them crashing down hard onto their knees. Pain flared, hot and sharp, but the adrenaline smothered it instantly. They scrambled up, hands slick with their own blood, and kept pushing into the suffocating dark.
The cavern was a labyrinth of jagged stalagmites and freezing puddles. Every ragged breath Monarch took felt like inhaling shattered glass.
Slap. Drag. Slap. Drag.
The sound of Harvey moving behind them was deliberate. He wasn't rushing. He was pacing them, letting the heavy, wet slither of his massive tail against the stone act as a terrifying metronome for Monarch's panic.
"Left," The siren’s voice echoed, though it sounded like it was coming from inside Monarch's own head, melodic and teasing.
Monarch veered right, driven by sheer defiance. They squeezed through a narrow fissure in the rock, the rough stone tearing their soaked jacket, and burst out into a smaller, pitch-black chamber.
They hit a solid wall. A dead end.
Monarch spun around, chest heaving, pressing their back against the cold stone. They strained their eyes against the absolute darkness, waiting for the monster to breach the gap.
Silence.
For a long, agonizing minute, there was nothing but the sound of Monarch's own frantic heartbeat drumming in their ears. They held their breath, praying that somehow, they had lost him.
Then, a faint, blue bioluminescent glow flared to life directly above them.
Monarch snapped their head up. The Siren was clinging effortlessly to the cavern ceiling, his long, scaled tail wrapped securely around a thick stalactite. His glowing eyes stared down at them, his head tilted upside down, that impossible, needle-toothed smile still plastered across his pale face.
He dropped, landing with a heavy, wet thud right at Monarch’s feet.
Monarch tried to scream, but the siren’s icy, webbed hand snapped out, wrapping around their throat. He didn't squeeze hard enough to strangle, just enough to effortlessly pin them to the rock wall, lifting them until the tips of their boots barely scraped the floor.
He leaned in close, the smell of salt and deep-sea ice rolling off him.
"I said left," he whispered, his breath freezing against Monarch's trembling skin.
With a casual flick of his wrist, he tossed Monarch aside. They hit the stone floor hard, tumbling over the slick rocks until they slid right back to the edge of the freezing underground pool they had just desperately tried to escape.
The siren followed, slithering past them and sliding back into the water with a satisfied, echoing splash. He sank beneath the surface, leaving nothing behind but the ripples, the biting cold, and the horrifying realization that there was absolutely nowhere to run.
Monarch lay there, limbs tangled and aching, waiting for the killing blow.
But the cavern remained agonizingly still. The water smoothed out, turning back into a flat, black mirror. The only sound was Monarch's own ragged, hyperventilating breaths bouncing off the damp walls.
Minutes bled into hours. The adrenaline crashed, leaving behind a profound, bone-deep cold. Monarch’s teeth began to chatter so violently it hurt their jaw. They pulled their soaked jacket tighter around themselves, curling into a miserable ball on the unforgiving stone. They didn't dare close their eyes. Every time their heavy eyelids drooped, a faint, taunting splash would echo from the pool, or a single claw would scrape deliberately against the rock underwater, snapping them awake in blind terror.
He was still there. Waiting. Watching.
Deep beneath the surface, a faint, sapphire light pulsed in rhythm with Monarch's shivering. Then, the humming started.
It was a slow, hauntingly beautiful melody that vibrated through the water and seeped into the rock itself. It wasn't a lullaby meant to soothe; the pitch was just slightly off, designed to dig under their skin, keeping their nerves raw and their mind fracturing. It was a constant, auditory reminder that they were not alone, and they were not safe.
Monarch squeezed their eyes shut, burying their face in their bleeding hands as another violent tremor wracked their spine. As the freezing dark pressed in from all sides, the horrifying truth finally settled over them.
Harvey wasn't going to kill them tonight. He was just going to make sure they stayed awake to feel every agonizing second of it.
