Ghosts don't have hearts.
Arin repeated the words to herself like a mantra, a shield against the memory of Zev's face. The hurt in his eyes had been a blade, and it had cut deeper than she would ever admit. Now, standing before the gaping maw of the old aqueduct, the only thing that mattered was the cold, hard shell she had built around that wound.
The air that breathed from the tunnel was ancient and foul, a stench of decay and forgotten things. Above, the sky was a tapestry of deep indigo, punctured by the first indifferent stars. The distant sounds of Caelvoryn—a faint, festive melody, the far-off roar of a dragon settling in its roost—were from another world. A world they were about to tear open from the inside out.
Zev stood beside her, a shadow made of silence and coiled tension. He hadn't spoken a word since her rejection. He simply moved with a stark, brutal efficiency. He was a tool for the job now, and she was its wielder. It was cleaner this way. It was safer.
It was a lie, and it was eating her alive.
"Ready?" His voice was a rasp, devoid of any warmth.
Arin didn't answer. She pulled the silver moth mask over her face. The cold filigree was a shock against her skin. The world shifted, viewed through the delicate prison of the mask's eyeholes. She wasn't Arin anymore. She was the ghost.
She gave him a sharp nod. Together, they slipped through the grated entrance and descended into the veins of the beast.

The darkness was absolute, a physical pressure against the skin. The only sounds were the drip, drip, drip of water from the vaulted stone ceiling and the slick, unnerving echo of their footsteps in the shallow, stagnant stream. The beam from Zev's shuttered lantern cut a weak, trembling path ahead.
The silk of the midnight blue dress, hidden beneath her dark, practical tunic and leggings, felt like a joke. A noblewoman's gown in the guts of the city. Silas's maps were clutched in her hand, the parchment already feeling damp.
"The third junction, bear left," she murmured, her voice unnaturally loud in the oppressive quiet. "It should open into the main cistern tunnel."
They moved in tandem, a dance they had perfected over years of navigating the Gutter's treacherous rooftops. He would point out a loose stone; she would signal a patch of deeper water. There was no emotion in it. Only instinct. Survival.
Then they saw it. The tunnel Silas had marked was gone. A mountain of collapsed rock and rubble blocked the path, the stones slick with algae. A cave-in, decades old by the look of it.
Silas's maps were fifty years out of date.
"Damn it," Arin hissed, the curse swallowed by the dark. She ran her hands over the rubble. It was impassable.
Zev shone the lantern beam around the small cavern. His light caught on a smaller opening to their right, a maintenance pipe barely wide enough for a child to crawl through. A dark, viscous liquid oozed from its mouth.
"There," he said, his voice flat. "It might connect to the cistern farther down."
It might. Two words to build a death sentence on.
Arin stared at the pipe. Her throat tightened. She wasn't afraid of heights, or knives, or men with dead eyes. But tight, enclosed spaces made her breath catch, her heart hammer against her ribs like a trapped bird.
She gave Zev a curt nod. There was no other choice.
He went first, pushing their satchel of tools ahead of him. Arin followed, forcing herself into the cold, narrow pipe. The stone was slick with slime and scraped against her back and shoulders. It was a tight fit, the space so confined she could feel the stone press in on all sides. Panic, cold and sharp, pricked at the edges of her control.
Ghosts don't have hearts. Ghosts don't have lungs. Ghosts don't suffocate in the dark.
The pipe was half-submerged in icy, foul-smelling water. It soaked through her leggings, the expensive silk of the hidden gown turning heavy and cold against her skin. It felt like the palace was trying to drown her before she even reached it.
They moved inch by painful inch, the only sound their own ragged breathing and the scrape of their bodies against the stone. For ten agonizing minutes, they were worms in the earth, blind and buried.
Then, light. Zev kicked open a rusted grate at the other end, and they tumbled out into a much larger tunnel, gasping for air that was only marginally cleaner than what they had left.
They were under the palace now.
She knew because the sound was clearer here. Through the thick stone ceiling, a faint, ghostly melody drifted down to them—a waltz. The muffled, rhythmic pulse of drums and the hum of a thousand noble voices, laughing, gossiping, scheming.
They were dancing on her grave, and they didn't even know it.
The injustice of it was a bitter pill. The people up there, draped in jewels worth more than her life, more than Finn's life—they floated through the world, protected by their names and their dragons. Down here, she and Zev fought through filth for a single breath.
A flicker of torchlight ahead.
"Down!" Zev whispered, pulling her into a shallow alcove carved into the wall.
They pressed themselves back into the damp stone, their bodies flush against each other. Arin's heart leaped into her throat. She could feel the heat of his body, the solid presence of him just inches away. The ghost and her ghost. The memory of his kiss was a phantom pressure on her lips.
Two cellar guards trudged past, their armor clanking. They weren't the elite Dragon Guard, just palace grunts assigned to the dregs.
"Can you believe it?" one of them grumbled, his voice echoing in the tunnel. "The whole court gets wine and roasted boar, and we get to patrol the bloody sewers for river rats."
"Better than patroling the Dragon Roost," the other countered. "Heard Prince Therain's beast screamed for an hour straight last night. Gave one of the handlers a heart attack."
The guards passed, their voices and their torchlight fading down the corridor. Arin let out a breath she hadn't realized she was holding. She was still pressed against Zev. For a moment, neither of them moved. It was the closest they had been since the rooftop.
She pulled away first, the cold air rushing into the space between them. "Let's go."
***
The base of the dumbwaiter shaft was exactly where Silas had said it would be. A tall, black chimney of stone disappearing into the darkness above. Set into the wall was a series of rusted iron rungs, ascending into nothing.
"The easy part," Zev murmured, a hint of dark irony in his tone.
Arin went first. The rungs were slick with moisture and God-knows-what else. Each one groaned under her weight. She tested every hold before trusting it, her fingers aching from the cold and the strain. She was a spider, climbing a black thread toward the heart of a web.
Halfway up, she heard a sharp crack from below, followed by a grunt of pain from Zev.
She looked down. He was dangling by one hand, his feet scrabbling for purchase against the slick stone. The rung beneath him had broken away, plummeting into the darkness with a distant, clattering splash.
"Zev!"
"I'm alright," he grunted, his voice strained. He swung his body, his free hand searching blindly for the next rung up. His fingers scraped against the stone, finding nothing.
Without thinking, Arin descended two rungs, bracing herself. She reached down, her hand outstretched. "Grab on!"
He looked up, his face pale in the gloom. He reached, his fingers brushing against hers. For a terrifying second, she thought he would fall. Then their hands locked, her grip like a vise. She pulled, muscles screaming in her arm and back, as he found a new foothold.
He was safe. He clung to the ladder, his breathing heavy. Their hands were still clasped together. A real, solid connection. Not a ghost's touch.
She let go as if burned. "Be more careful."
"My apologies," he said, his voice flat, and they continued their ascent in silence.
***
The top of the shaft ended in a small, cramped platform. Before them was a heavy stone door, sealed with a lock that looked as ancient as the palace itself. This was it. The final gate.
Zev pulled out his tools, his movements once again economical and precise. Arin held the lantern, its narrow beam focused on the complex lock. She could hear her own heart, a frantic drum against the silence. The muffled music from the masquerade was louder here, a constant, taunting reminder of the world just beyond the stone.
Minutes stretched into an eternity. Zev worked, his brow furrowed in concentration. The only sound was the delicate, metallic click and scrape of his picks inside the lock.
Click.
Scrape.
Click.
Then, a soft, final thunk.
He did it.
Zev looked at her, his dark eyes unreadable in the lantern light. He nodded. Arin took a deep breath, holstering the lantern. She drew the slim, wicked-looking knife from her boot. Just in case.
Zev put his shoulder to the stone door and pushed. It moved silently, a testament to ancient engineering, swinging inward on perfectly balanced hinges.
They were in.
But the space beyond was not the dusty, forgotten alcove Silas had described.
It was bathed in a soft, pulsing blue light. The light emanated from a series of glowing runes carved into the floor, forming a shimmering, ethereal barrier that blocked the path. A ward. One Silas hadn't known about. It hummed with a low, magical energy that made the hairs on Arin's arms stand on end.
It was a trap. A new, unexpected layer to the cage.
And then she heard it. A sound from the other side of the Reliquary wall—the wall they were supposed to break through.
It wasn't the clank of a guard's armor or the murmur of a patrolling priest.
It was a quiet, rhythmic scraping. A delicate, metallic whisper.
The sound of a lockpick.
