The Last Oracle of Rust She reads trash prophecies—and four lords may burn her city alive. #9
Julian’s, almost silent except when it broke around the name he had just read.
Elian Vale.
Mara held the matchbook in her shaking hand.
DO NOT SAVE THE CITY.
SAVE THE MEN.
THEY ARE THE LOCK.
YOU ARE THE FIRE.
The words did not fade. They burned brighter in the dark, written in her sister’s hand, impossible and intimate and cruel enough to be true.
Ronan came to her first.
Not grabbing. Not ordering.
He stopped close enough for his heat to reach her and held out one hand.
“Mara.”
Her name sounded different now. Not like a command. Not like a warning.
Like an oath he was afraid to make badly.
She stared at his hand. “If I take it, do you drag me somewhere safe?”
His mouth tightened. “There is no safe.”
“No.”
“No,” he agreed. “But I can stand between you and whatever comes first.”
She wanted to laugh. She wanted to cry. Instead, she slipped her hand into his.
His fingers closed around hers with devastating care.
Silas exhaled from behind them. “Hate to interrupt an emotionally devastating moment, but the tunnel in front of us is glowing like a murder invitation.”
Dacre turned toward the passage ahead.
The air beyond it shimmered orange, hot enough to make moisture bead on the tiles. Far above, through pipes and vents and unknown chambers, Hollowgrave roared. Not the monsters this time.
People.
Riots.
The city had heard the prophecy broadcast. It had seen Mara’s face. It had learned the monster gates were open, the Heart Engine was dying, and the last oracle stood at the center of all of it.
Now factions were turning on one another.
Mara heard the violence through the bones of the city.
Iron Dredge shields slamming against Wiremarket barricades.
Archivist lanterns shattering. Tunnel fighters howling warnings no one understood.
The council shouting for containment, for sacrifice, for possession, for anyone with enough courage or stupidity to seize the oracle and force salvation from her body.
Hollowgrave was not dying quietly.
It was trying to survive the only way it had ever known how.
By choosing someone else to feed the dark.
Julian stepped beside Mara, the offering tag clenched in his gloved hand. His voice was hoarse. “The old records were not warnings. They were instructions.”
Silas’s eyes narrowed. “For sacrificing oracles?”
“For repeating success.” Julian looked sick. “Every generation that reached collapse found a woman with enough prophecy in her blood, bound her to enough power, and fed the result into the Engine. They called it divine exhaustion. A necessary ending. The cost of keeping Hollowgrave alive.”
Ronan’s rustblood flared so hot the tunnel walls reflected red. “Who knew?”
Julian did not look away. “The Archive knew pieces. The council knew more. The Heart Engine priests knew everything.”
“And you?” Mara asked.
The question hurt him. She felt it through the bond before it touched his face.
“I knew there were missing histories,” he said. “I knew names had been removed. I knew your sister’s death report had been sealed by more than law.” His voice nearly broke. “I thought uncovering the truth later would be enough.”
Mara’s grief was a blade. His guilt did not dull it.
But she could see him now. Not the composed archivist with velvet voice and careful gloves. A man standing under the weight of every truth he had failed to save in time.
“Later is where Hollowgrave buries everything,” she said.
Julian bowed his head. “Yes.”
Dacre moved first.
His claws scraped the tile as he stepped into the orange-lit tunnel. “Then we stop burying.”
They followed him down.
The tunnel sloped beneath the city, past walls where old advertisements peeled in strips and every smiling surface face had been scratched out.
The heat thickened with each step. Rust dust floated in the air, glowing like fireflies.
Mara tasted ash, salt, and prophecy. The matchbook in her hand warmed until she tucked it against her heart.
The rust mark had spread across her chest, over her shoulders, down both arms. It did not feel like a wound anymore.
It felt like a fuse.
At the end of the tunnel stood a door made of welded subway gates, bones, and iron chains.
Dacre placed his palm against it.
The door shuddered.
From the other side came a low, wet breath.
Silas swallowed. “I would like to officially register my preference for not opening that.”
Ronan’s hand tightened around his blade. “Noted.”
Julian whispered a word in the old archive tongue.
The chains unlocked.
The door opened inward.
The Heart Engine chamber waited beyond.
Mara had seen it in visions, but visions were merciful. They left out the scale. The heat. The smell.
The chamber was a vast underground cathedral, so large its ceiling vanished into smoke.
Pipes climbed the walls like organ tubes.
Gears turned slow as planets. Chains thicker than men stretched from iron pillars to the thing suspended in the center.
Bones were built into the architecture—not scattered, not hidden, but placed with reverence.
Human bones. Monster bones. The bones of sacrifices and saviors and all the people Hollowgrave had renamed necessary.
Molten orange light poured from below, rising through grates in the floor. It licked Mara’s skin. Sweat slid down her spine. The sharp smell of burning wire mingled with old blood and hot rust.
And there, hanging beneath the city like a living furnace, was the god.
The Heart Engine.
The chained rust god was enormous, its body fused from pipes, teeth, gears, scraps, and memory.
Its skin was layered with trash prophecies: receipts, torn letters, coffee cups, ration cards, wedding vows, children’s drawings, funeral notices, love notes never sent.
Every discarded thing trembled as they entered.
Its many eyes opened.
Mara’s knees nearly gave.
Ronan caught her from behind, his arms locking around her as the chamber shook.
The god smiled with its stitched mouth.
LITTLE ORACLE.
The voice moved through the pipes, the bones, the chains, the trash, her teeth.
YOU CAME BURNING.
Mara pressed back against Ronan’s chest because if she did not lean on something, she would fall.
His heartbeat thundered through the bond like a hammer.
“Do not listen alone,” he said against her hair.
Something inside her ached at that.
Not because he sounded possessive.
Because he did not.
Silas staggered as dead consoles lining the chamber sparked to life. “The grid is still connected down here.”
Julian stared upward, horror and wonder on his face. “The Engine is tied to every memory vault.”
Dacre’s claws flexed. In the shadows around the chamber, dozens of eyes opened. Tunnel creatures. Monsters from the unlocked gates, drawn by the god’s hunger. Long-limbed things clung to pillars. Pale mouths opened in the dark. Bone-backed beasts crawled along the grates.
Dacre stepped between them and Mara.
One monster hissed.
Dacre answered with a roar.
It shook dust from the ceiling.
The creatures went still.
The god laughed through the pipes.
YES. brING ME TEETH. brING ME IRON. brING ME LIGHT. brING ME MEMORY.
Its chains strained.
Outside the chamber, the riot above surged louder. Mara heard the city screaming for her. Save us. Burn her. Bind her. Use her. Crown her. Kill her.
The trash layered over the god’s skin began to write.
LOVE THEM ALL, AND HOLLOWGRAVE BURNS.
REFUSE THEM, AND SHE DOES.
The old prophecy.
The trap.
Mara stared at it until the letters blurred.
All her life, she had believed visions were fixed.
A prophecy came written in trash because trash was what remained after choice.
It was the receipt after hunger. The letter after abandonment.
The cup after thirst. The wrapper after sweetness.
The proof that something had happened and could not be undone.
But standing there beneath Hollowgrave, with her sister’s final message burning against her heart, Mara understood.
Trash was not only what was left behind.
It was what people decided they no longer needed.
Abandoned choices.
Hidden truths.
Rejected love.
Broken promises.
Futures thrown away before anyone had the courage to salvage them.
Prophecy was not a clean road.
It was a pile of wreckage.
And wreckage could burn.
The god’s stitched mouth opened wider.
LOVE THEM, it whispered.
The chamber showed her visions.
Ronan, consumed first. His rustblood ripped from him in molten strands, his body turned into a shield around the Engine until nothing remained of the man beneath the weapon.
Silas, plugged into the grid, his clever mind burning bright enough to power a district for one final night before going dark forever.
Dacre, chained among monsters, his feral heart used to command every hungry thing beneath Hollowgrave.
Julian, emptied of memory after memory, whispering names until he forgot his own.
And Mara, alive above their ashes.
Spared.
Worshiped.
Alone.
OR REFUSE, the god said.
The vision changed.
Mara fused into the Engine. Her bones becoming pipes. Her blood becoming heat. Her mouth stitched open forever so prophecy could pour through her until every word belonged to Hollowgrave and nothing belonged to her.
The god leaned closer.
CHOOSE.
Mara shook.
Not from fear.
From fury.
“No.”
The god’s eyes narrowed.
NO?
“No.”
The chamber groaned.
Ronan’s arms tightened around her. “Mara.”
She turned within his hold and looked up at him. Really looked.
At the scar through his brow. The iron glowing under his skin. The fear he carried that he would only ever be useful as a weapon.
“You are not my shield because they made you one,” she said.
His breath caught.
“You are not a thing to spend before me.”
Ronan’s face hardened as if the words hurt more than the poison blade had. “I would let it take the rustblood first.”
“I know.”
His eyes burned.
“That is why I won’t.”
She touched his chest.
The bond flared.
Then she turned to Silas.
He stood by the central console, the dying grid already reaching for him in blue-white arcs. His smile trembled at the edges, but he offered it anyway.
