The Cartographer Who Weighed the Choir’s Song
The water reached Corin’s knees before he found the ledge. Bram’s grip on his arm was iron, the stump of his missing hand pressed tight against his chest, but his legs were steady as he half-carried Corin through the rising current. The workshop behind them was gone—swallowed in a roar of black water that had torn Master Oren’s maps from the walls and sent them spiraling into the dark like drowned birds.
“There!” Sable’s voice cut through the chaos, sharp and clear. She was already on the ledge, a narrow shelf of stone that ran along the tunnel’s ceiling, her hand extended. “Grab hold.”
Corin lunged, his fingers catching the rough edge of the stone. The water tugged at his boots, greedy and insistent, but Bram’s palm slammed into his back and shoved him upward. He scrambled onto the ledge, gasping, and turned to haul Bram up beside him. The ex-soldier moved with a soldier’s economy—no wasted motion, no panic—but Corin saw the way his jaw clenched as he used his one hand to pull himself onto the shelf.
Sable was already moving, her lantern held high, casting long shadows across the flooded tunnel. “We need to keep moving. The Choir won’t stop at one flood. They’ll send hunters behind it.”
“They flooded the Undermarket,” Corin said, his voice hoarse. “There are people down here. Merchants, smugglers, families.”
“There were people down here,” Sable corrected, and the flatness in her voice made Corin’s stomach turn. “The Choir doesn’t do half measures. If they decided to flush us out, they’ve already sealed the exits. Everyone who didn’t get out in time is dead.”
Bram made a low sound in his throat—not a word, but a vibration that Corin felt through the stone. He’d learned to read Bram’s noises in the weeks since they’d fled the surface. That one meant *agreement*, and it was the most terrible sound Corin had ever heard.
They moved in silence for a time, following the ledge as it wound through the dark. The water below them churned and slapped against the walls, and every so often Corin heard something bump against the stone—a crate, a barrel, a body. He tried not to think about the bodies.
The tunnel opened into a wider chamber, and Sable stopped so abruptly that Corin nearly walked into her. She was staring at the far wall, her lantern trembling in her hand.
“That’s not possible,” she whispered.
Corin followed her gaze. The wall was covered in a mural—painted in faded blues and greens, the colors bleeding into one another like watercolors left in the rain. It showed a city rising from the sea, towers and spires reaching toward a sun that was half-submerged in the waves. At the center of the city, a great beast coiled around the foundations, its body wrapped through the canals like a serpent through a garden. Its eyes were painted gold, and even faded and chipped, they seemed to watch Corin as he approached.
“The Sunken Gardens,” Sable said. “I thought this chamber was sealed. The histories said the Gardens were destroyed in the first flood.”
“They were,” Corin said slowly. “But this isn’t a garden. This is a record.”
He stepped closer, his fingers hovering over the painted beast. The mural was old—centuries old, by the look of the pigments—but the details were still sharp. He could see the chains wrapped around the beast’s body, each link painted with a tiny symbol. He recognized some of them from Master Oren’s workshop: tide marks, flood lines, the angular script of the Tideborn Council’s earliest edicts.
“The first Tideborn used the leviathan’s blood to build the city,” Corin murmured, repeating what he’d read in Oren’s notes. “They didn’t fight it. They *used* it.”
“That’s not what the Choir teaches,” Sable said. Her voice was tight, controlled. “They teach that the leviathan is a curse. A punishment for the sins of our ancestors. They teach that the floods are penance.”
“They teach what serves them.” Corin turned to face her. “Sable, you were a priestess. You know the rituals. The songs. What do they actually *do*?”
Sable was silent for a long moment. The lantern light flickered across her face, catching the sharp lines of her jaw, the shadows under her eyes. She looked older than she had when they’d first met, Corin thought. They all did.
“They feed it,” she said at last. “The Choir’s songs aren’t prayers. They’re commands. They tell the leviathan to sleep, to dream, to *grow*. Every flood that drowns a district isn’t a sacrifice to keep it calm—it’s a meal. The water carries the life of the drowned down into the deep, and the leviathan drinks it.”
Corin felt the words land like stones in his chest. “That’s monstrous.”
“It’s worse than monstrous.” Sable’s voice cracked. “I didn’t know. When I was a priestess, I believed the songs were keeping the city safe. I believed the floods were a necessary evil, a price we paid for the privilege of living on the water. But then I saw the records. The *real* records, hidden in the Choir’s vault. The leviathan isn’t a guardian. It’s not even a prisoner. It’s a *weapon*.”
“A weapon for what?” Bram’s voice was rough, unused to speech. He rarely spoke, preferring the language of vibration and gesture, but when he did, his words came out like stones tumbling down a hill.
Sable met his eyes. “For the war that’s coming. The Tideborn Council has been feeding the leviathan for a century, building its strength. They believe that when it wakes, it will be the most powerful force in the world. And they intend to be the ones holding its leash.”
Corin’s hand dropped from the mural. “They’re not trying to keep it asleep. They’re trying to *awaken* it.”
“On their terms,” Sable confirmed. “When they’re ready. When it’s strong enough to do what they want.”
The chamber fell silent. Even the water seemed to hold its breath, the lapping against the walls growing faint, as if the city itself was listening.
Corin turned back to the mural. The beast’s golden eyes stared at him, patient and ancient. He thought of the child who had drowned in the first flood—the one he’d marked as safe on his map. He thought of Bram’s hand, lost to a collapsing tunnel. He thought of Master Oren, broken and drawing the same spiral over and over, whispering about the King who slept in the ink.
“How long?” he asked. “How long until they’re ready?”
“I don’t know.” Sable’s voice was barely audible. “Months, maybe. Years. But the signs are there. The floods have been getting worse. The Choir has been singing more often. They’re accelerating the process.”
Corin’s gaze swept the mural, searching for something—a clue, a key, a way out. His eyes caught on a detail he’d missed: at the base of the city, where the beast’s tail curled around the foundations, there was a small door. It was painted in the same faded blues as the rest of the mural, but it was distinct, its edges sharp and deliberate. Above it, in the angular script of the Tideborn, was a single word.
*Throne.*
“Sable,” Corin said, his voice suddenly tight. “What do you know about the Dry Throne?”
She frowned. “The Dry Throne? It’s a myth. A legend about a chamber beneath the palace where the first Tideborn could control the city’s floodgates. Most scholars think it’s a metaphor.”
“It’s not a metaphor.” Corin pointed at the mural. “It’s there. In the painting. The door is marked with the same symbol Master Oren used in his workshop. The spiral with the dot at the center.”
Sable stepped closer, squinting at the faded paint. “That’s just decoration. The artists of the old city loved their flourishes.”
“It’s not decoration.” Corin’s voice was firm. “I’ve spent my life reading maps, Sable. I know a coordinate when I see one. That door isn’t part of the city—it’s *under* it. Beneath the palace, beneath the canals, beneath everything. If we can find it, we can control the floodgates. We can stop the Choir.”
“You want to find a mythical chamber based on a painting in a flooded ruin?” Sable’s laugh was bitter. “Corin, we’re trapped in a tunnel with the Choir hunting us and the water rising. We don’t have time for legends.”
“We don’t have time for anything else.” Corin turned to face her fully. “The Choir is going to keep flooding the city until they’ve flushed us out or drowned us. The only way to stop them is to take control of the system they’re using. The Dry Throne is the key. I know it is.”
Bram made a sound—a low hum that vibrated through the stone. Corin looked at him. “What?”
Bram’s eyes were fixed on the mural. He raised his one hand and pointed at the door, then at the beast’s golden eyes, then at the chains wrapped around its body. He made a gesture Corin had learned to recognize: *connected*. *The same.*
“The door is chained to the beast,” Corin said slowly. “The Throne isn’t just a control room. It’s a lock. The same mechanism that holds the leviathan also powers the floodgates.”
Sable’s eyes widened. “If that’s true, then the Choir isn’t just feeding the beast. They’re using the Throne to do it. They’re the ones holding the chains.”
“And if we can reach the Throne,” Corin said, “we can break them.”
The water below them had stopped rising. It lapped against the ledge, patient and waiting, as if it too was curious to see what they would do next. Corin pulled out his charcoal and a scrap of parchment from his satchel—the satchel he’d somehow managed to keep dry through everything—and began to sketch.
“The mural gives us the layout,” he said, his hand moving quickly. “The door is beneath the palace, but it’s not directly below. It’s offset, angled toward the east. That matches the spiral Master Oren drew. The center of the spiral isn’t the palace—it’s the old harbor.”
“The old harbor is underwater,” Sable said. “It’s been flooded for fifty years.”
“Exactly.” Corin’s charcoal scratched across the parchment. “The Choir would never think to look there. It’s the one place they’ve written off as lost. And it’s the one place where the water is deepest—which means it’s the one place where the leviathan’s chains are closest to the surface.”
Bram grunted. He pointed at the sketch, then at his own chest, then at the tunnel ahead. *I’ll lead.*
“You can’t,” Corin said. “You’re hurt.”
Bram’s eyes were flat. He pointed at his missing hand, then at the water, then at Corin. *I can feel the currents. I can find the path.*
Sable touched Corin’s arm. “He’s right. Bram’s sense for vibration is the only thing that’s kept us alive this long. If anyone can navigate the flooded tunnels, it’s him.”
Corin looked at Bram—at the scarred face, the missing hand, the quiet certainty in his eyes. He thought of the map he’d drawn that had predicted the ambush, the map he’d ignored because he’d been too afraid to trust it. He thought of all the ways he’d failed the people who trusted him.
“Okay,” he said. “We go to the old harbor. We find the Dry Throne. And we break the chains.”
He folded the sketch and tucked it into his satchel. The water below them had begun to stir again, a slow current pulling toward the tunnel mouth. The Choir was still singing somewhere above, their songs vibrating through the stone like the pulse of a dying heart.
Sable extinguished her lantern. “We’ll need to move in the dark. The Choir can sense light.”
“Then we move in the dark,” Corin said. He reached out and found Bram’s shoulder, then Sable’s hand. “Together.”
They stepped off the ledge and into the water. It was cold, colder than it had been before, and it pulled at them with a hunger that felt almost personal. But Corin kept his grip on the others, and they kept moving, following the current toward the old harbor, toward the Throne, toward the truth that waited beneath the drowned city.
Behind them, the mural faded into the dark, the beast’s golden eyes watching them go. And for just a moment, Corin could have sworn he heard a sound—not the Choir’s song, but something deeper, older, rising from the depths of the sea.
It sounded like a chain, shifting in its sleep.
“There!” Sable’s voice cut through the chaos, sharp and clear. She was already on the ledge, a narrow shelf of stone that ran along the tunnel’s ceiling, her hand extended. “Grab hold.”
Corin lunged, his fingers catching the rough edge of the stone. The water tugged at his boots, greedy and insistent, but Bram’s palm slammed into his back and shoved him upward.
