THE SUNKEN VAULT

There was a stair.

It began just beyond the crack, and it went down in a long slow curve through stone that was no longer the red stone of the Gorge. The walls here were gray, dressed and squared by tools. The treads were deep, worn in the middle, wide enough for two to walk abreast. Every twenty steps, set into the wall, a bracket of black iron held a dead torch. I lit one with a flick of Cinder, and it caught with a wet pop and burned with a low, steady, orange flame. Whatever had been in the oil had not gone bad in sixty years. Or six hundred.

Nimbus rode on my shoulder, balanced on the unwounded side. He had refused to be carried. He had also refused to walk. The compromise, arrived at without discussion, was that he would ride, and that this was somehow my idea.

"The air is old," he observed.

"It's dry."

"It is old. It has been breathed before."

I stopped on the stair and listened. There was nothing. A faint ticking, perhaps, as of cooling metal. But in the dry air there was a sense of presence, a held quality, like a room in which someone has just stopped speaking.

I went on.

…

The Fourth Tier was not a tier at all.

It was a city, or the bones of one.

We came out of the stair onto a wide gallery that ran along the edge of a vast sunken hall, and I stopped dead with the torch in my hand. The hall ran away into the dark: a floor of paved stone, a hundred yards across, studded with pillars as thick as oaks. The ceiling was lost in shadow. Along the walls ran arcades, galleries, balconies. A great stair rose on one side to a platform where a statue stood, headless, in robes. There were doorways everywhere, and broken carts, and the stumps of what had once been banners. On a long marble table, a row of tin plates still stood in their places, dusty, set for a feast that had never been served.

On the wall above the stair, in bronze letters three feet high, was a name.

FIRST FORT.

"Founders' First Fort," I said slowly.

I had read of it. Everyone in Halvern had, in the first-year history. The first stronghold of the Republic, built by the Founders in the year of the Compact, where they were said to have made their stand against the Northern Marauders. It had fallen. It had been lost. Some said it had been sacked, others that it had been swallowed by an earthquake. No living scholar had ever found its ruins.

I was standing in them.

It had been buried deliberately. That was clear to me within the hour. There were no quake-cracks in the vault, no collapsed arches. The roof was whole. Only the way in had been closed. The Founders had built their fort at the bottom of a canyon, and then somebody had filled the canyon.

Why bury your own fort?

The answer, as it turned out, was written on the walls.

…

They had not left it plain. Every few yards, along the lower stretch of the main gallery, in a hand that was small and square and tireless, someone had cut words into the stone. Not carvings. Not inscriptions. Writing. A personal record, scratched with the point of a knife, line after line, in the old Founders' script that no one at Calloway could read fluently.

I could.

I'd learned it at fifteen, for sport, because a set of crumbling letters in the college archive had defeated every scholar in the faculty. I had thought it a harmless eccentricity. In the last life it had cost me nothing and gained me little. In this life, with a torch in my hand and a cat on my shoulder, it was the most valuable thing I owned.

I began at the first panel, and read.

The fourth day of the Third Month, in the year the Iron March ended. I am Hale, keeper of the East Wall. I write this because I am not certain, any longer, that anyone will believe us.

The General has been taken.

I moved my torch along.

It was not the Marauders. We told the people it was the Marauders. It was the Council. They came in the night with eleven Wardens and a warrant, and the General went without a word, because he is the only one of us who understood from the first what they meant to do. He said: it will be worse if I fight. He said: they need the Heart.

We asked what Heart.

He said: you will find out.

I stopped. My eyes had begun to burn, from the smoke or from something else. I read the next line twice.

The Tithe is a lie. It was always a lie. The Founders did not make it to keep the people safe. They made it to keep themselves in power.

The word was cut larger than the rest, and deeper. Tithe.

I had heard it before. Every child in Halvern had, the way every child knows the name of a bogeyman. The Tithe had been, in the oldest tales, a sacred obligation: a portion of every soul's gift, offered up at the Founders' Altar to keep the realm safe. A pious fiction. A relic of a savage age. It had been abolished three hundred years ago.

They did not abolish it, wrote Hale, in his tireless hand. They hid it.

They take it from the unmarked. The weak, the poor, the gifted without House. They draw it by night, a little at a time, so that the people grow sick and tired and do not know why. They feed it to the Houses. It makes the High Houses strong. It makes the Council strong. It keeps the Realm in their hands, and it takes the gift from everyone else.

The General found the Engine. He swore to break it.

They have sealed him in the Vault. I will not say where. If I live, I will go to him. If I do not, let whoever reads this know: the General is not a traitor. He is the only honest man the Republic ever had.

They call him the Sealed General. They will call him worse.

I took my hand off the wall. It was shaking.

Forty years. That was the number I had always known from the histories, and the name of the man was one of the few the textbooks had been unable to omit: Declan Marrow, the Warlord of the Iron March. A general who had turned on the Republic and marched on the Capital; sealed by the Senate for treason, forty years before I was born. A name to frighten children.

The dates on Hale's wall matched. The tone did not. Hale did not write like a man guarding a monster. He wrote like a man who had watched a friend be buried alive.

The Sealed General. Not the Warlord of the schoolbooks. Something else entirely.

The torch hissed. Nimbus's claws had gone into my shoulder, hard enough to prick.

"The Heart," he whispered. "It is singing."

I could feel it. For some time now, without my noticing, it had been rising: a slow warm throb in my chest, almost a pull, as of a tide. It pulled toward the deep end of the hall, where a black archway stood beneath the headless statue. Like a hound that has caught a scent.

"It knows this place," said Nimbus.

"So do I," I said, and did not know why I said it.

…

The first gate was made of light.

It stood at the end of a long, narrow antechamber behind the arch, a curtain of white radiance that hung from lintel to floor, so bright that it left shapes on my eyelids. Anyone who walked through it would be seared blind. I knew this because a man lay at its foot, long dead, a mummy of leather and bone in a Founders' coat, his eye sockets burned black.

I studied it for a minute. It was elegant. It was a Ward of Penetrating Radiance, an old working, pretty and simple: a lattice of mirrored runes cut into the lintel, each one reflecting its neighbor, building up the glare. The principle was a feedback loop.

I put my palm to the nearest rune, and let the Cinder flow.

The light guttered. It sagged like a sheet in the wind, bright and then dull, and then went out in a rush of cold, and the antechamber was dark. I took my hand away, and the stone under it was faintly warm.

"One," I said.

The second gate was a doorway of nothing. It looked like an ordinary arch, but a weight lay on it: a heavy dark pressure that bent the very light. When I took a step toward it, I felt my knees give. When I took a second, I went to my hands and knees on the floor. It was gravity, bent and turned, ten times the ordinary. The skeleton of a man in armor lay crushed flat inside the arch, like a pressed flower.

I crawled to the wall, found the rune with my fingertips, and burned it.

The weight lifted. I lay on the stone for a minute breathing, and Nimbus, who had been flattened to my back like a mat, climbed off and shook himself with outraged dignity.

"I dislike this place."

"You're welcome to wait outside."

"That is not what I meant."

The third gate was a whisper.

It was not a doorway, exactly. It was a corridor, long and straight and absolutely black, and as I stepped into it I heard my name.

Tamsin.

It was a woman's voice, soft, close behind my ear. It was my mother's. I had been four when she died, and I did not remember her voice. But I remembered this.

Tamsin. Come home.

I stopped. My heart was pounding. In the darkness I could feel the Heart in my chest, hot as a brand, and under it the cold small thread of a doubt.

Come home, little love.

"No," I said aloud.

The whisper hesitated. Then it changed, as a river changes, and it was Alden's voice, warm, and low. Tamsin. I'm sorry. I'm so sorry. Please come back.

"No," I said again, and laughed, and was astonished at the sound. I had expected it to hurt. "You're not even good at this." I found the rune on the wall. It was a ring of tiny interlocking ears, carved in the stone. Clever. "A Ward of Whispers feeds on what you most want to hear. It is quite effective, I'm told, on people who want things."

I burned it.

The whisper broke off in the middle of a word.

In the silence afterward I realized that I was smiling, and that my face was wet.

…

At the end of the corridor stood a door.

It was low and heavy, banded with black iron, and it had no handle. It had no ward. It had no rune. It stood in the stone like something that had grown there, and when I laid my palm against it I felt a hum run up my arm, a deep slow vibration, as of a great engine turning at the bottom of the world.

"Do not," said Nimbus. It was the first time I had heard fear in his mind-voice. "This one is not a door."

"I know."

"Then why—"

I did not answer. I could not have said. It was the Heart, perhaps, or it was something older: the fever of the dead girl I had been, who had died in a stadium without ever knowing what she had held. I pressed my hand flat to the iron and pushed.

It swung open without a sound.

The room beyond was huge and round and bare. The walls were black glass. A high dome roofed it, cut with a single round window, through which a shaft of moonlight fell, pale and cold, onto the floor. In the center of the floor, in the moonlight, stood a figure.

He was tall. He was impossibly tall, bound upright in a lattice of glowing chains that ran from his wrists and ankles and throat and chest to bolts in the walls: nine of them, each as thick as my wrist, bright as lightning, humming. They wound around him in loops and coils, binding his arms to his sides, cinching his chest. They glowed white-gold where they touched his skin.

His head was bowed. His hair, black and long, hung over his face.

I stood in the doorway and did not breathe.

Then the head lifted, and the hair fell back, and a pair of eyes opened in the dark: gray as the edge of a knife, and as awake as a blade.
