Prologue

My sister disappears from the royal genealogy at three minutes past midnight.

I know the exact moment because I am holding the brush that erases her.

The Hall of Ancestral Names is closed to everyone except the dead king’s bloodline, three senior archivists, and me. I am present because reputations must be prepared before bodies are buried, and King Yeong-su has left behind more stains than a lifetime of incense can hide. Outside, carpenters hammer together his funeral dais. Inside, a hundred lacquered cabinets breathe dust into the candlelight.

On the table before me lies the Han family register.

Han Seo-yeon, Royal Ritual Director, remains written in black.

Han Min-ji, younger daughter, is becoming a pale scar in the paper.

“Press harder,” says Minister Gwon.

He stands across the table in mourning white, his hands folded inside immaculate sleeves. He is old enough to have served three kings and careful enough to have loved none of them. The black bead on his official hat trembles whenever the funeral drums test a new rhythm in the courtyard.

I stop the brush.

“The fibers will tear.”

“Then mend them.”

“A repaired register invites questions.”

“Only if someone remembers what was removed.”

He places two fingers on the page and slides them over my sister’s fading name. The ink lifts into his skin like smoke. For a heartbeat, he wears Min-ji’s final memory across his knuckles: her hand reaching through prison bars, her mouth shaping my name, the red cord around her throat.

Then the image sinks beneath his cuff.

My stomach turns. I keep my face still.

Faces are the first instruments of power. A royal court can forgive treason more readily than an uncontrolled expression.

“The late king’s final decree was explicit,” Gwon says. “Your sister conspired with mountain rebels. Her name is to be removed before the funeral, so her shame cannot contaminate His Majesty’s ascent.”

“The late king’s decree was dictated while he was fevered.”

“His fever is not part of the public record.”

Of course it is not. I wrote that record.

For six years, I have made the royal household look inevitable. I chose which omens were auspicious, which affairs were patriotic sacrifices, which executions were merciful necessities. When a prince struck a servant, I arranged a donation to the servant’s village. When a concubine drowned, I transformed the lake into a memorial garden. I understand the distance between truth and belief better than priests understand prayer.

But I cannot create a story in which Min-ji deserved the rope.

I set the brush down.

Minister Gwon’s gaze settles on my hand. “Do you refuse?”

The correct answer is immediate obedience. Hesitation is a crack, and cracks become rumors.

Before I can speak, something knocks inside the northern wall.

Once.

Twice.

Three times.

The archivists freeze.

The wall is solid stone. Behind it lies the sealed mirror gallery, abandoned since the treaty with the dokkaebi court failed thirty years ago. No human is permitted to open it after moonrise.

Another knock sounds, lower this time, followed by the scrape of a claw across silver.

Minister Gwon’s composure slips. It lasts less than a breath, but I see it.

“Continue,” he orders.

I pick up the brush.

The candle flames bend north.

In the polished black inkstone, a reflection appears behind me: a man too tall for the archive, dressed in robes the color of storm clouds. One horn curves from his dark hair. Obsidian scales climb the side of his throat. His eyes are entirely black.

Mu-jin.

The Dokkaebi King.

I do not turn. Reflections are doors for his kind, and acknowledgment is an invitation.

His reflected mouth curves.

You trade names cheaply, Director Han.

The words do not enter through my ears. They unfurl behind my eyes in a voice that tastes of rain on iron.

My brush touches the page.

What will yours cost?

I drag the wet bristles across Min-ji’s final syllable.

The character blurs. The paper drinks. Somewhere in the palace, a bell rings once though no hand pulls its rope.

My sister is gone.

Not dead. Death leaves a shape in memory. This is worse. The register’s magic reaches outward through every family altar and ancestral tablet in the kingdom. By dawn, cousins will forget her laugh. Servants will forget which room was hers. The women who braided her hair will remember only that their fingers once moved for some unnamed purpose.

I grip the table until my nails ache.

In the inkstone, Mu-jin watches me as if my restraint is a delicacy.

Minister Gwon closes the register. “You will direct the king’s funeral at sunrise. The generals intend to use the mourning rites to contest the succession. You will ensure they kneel.”

“And if they do not?”

“Give them a reason.”

The archivists gather the brushes and sealing wax. No one looks toward the northern wall. No one mentions the claw marks now appearing across its silver inlay.

Gwon pauses at the door.

“One more matter. The Dokkaebi King has demanded attendance.”

The inkstone goes dark.

“At a human funeral?” I ask.

“He claims the dead king owed him a reputation.”

“Reputations are not property.”

Gwon gives me the thin smile of a man who has just watched me erase my own sister. “Everything is property if a court agrees upon the price.”

He leaves.

I remain alone with the closed register. Through the shutters, the eastern sky begins to pale. Funeral smoke pools over the courtyard, carrying sandalwood and fear into the archive.

I open the book again.

Where Min-ji’s name once lay, a new line has written itself in silver:

HAN SEO-YEON — LOT ONE.

Beneath it gleams the seal of the Dokkaebi King.

The letters vanish when I blink, but their weight remains against my throat.

I wash the brush, straighten my mourning robes, and practice the expression I will wear before the court. Serene. Loyal. Unbreakable.

By sunrise, I must force two enemy factions to grieve as one body.

And somewhere beyond the courtyard, a monster is coming to bid on my face.
