The Seventh Kingdom

The new trilogy · by Cody Mathew

Forthcoming — Coming Soon

The Willing Shadows

A coronation, a fleet at anchor at dawn — and not one shadow on the water.

The War Beneath the War

Every war has the one on the field — and the one fought underneath it, in whispers.

Coming Soon
Book Three

Title Not Final

The World

The Seven Kingdoms

Six crowns signed the truce. The map below — printed in the front of every book — shows all seven kingdoms, the sealed cave, and the sea the seventh kingdom rules.

Tap to enlarge

Faces of the Saga

The Kingdoms, Briefly

King Osric

Osric’s Kingdom

The capital and the great signing hall — seat of the realm, and the place the letter’s journey begins.

King Morthkar

Morthkar’s Kingdom

Ash wastes, the land of the Dead. Its king lies sealed in a tomb by the Witch Queen’s curse — and his armies are not forgotten.

King Ostran

Vessan

The river kingdom, rich on the Silverreach’s trade, with Bendwater at its bend.

King Edmar

Brannock

Horse-plains and open steppe — a kingdom of riders, grass, and long horizons.

King Haldor

Karsk

Mountain and iron. Stone Pass cuts through Karsk — and something very large guards it.

King Loric

Fenmark

The marsh kingdom: swamps, fog, and the weakest of the six crowns — the door others watch.

Across the Sea

Morvane

The seventh kingdom, a sea power ruling its own waters — the name left off the truce, and the subject of the new trilogy.

The Sworn Five

The Five Seals

Kael, Beck, Oda, Brak and Dern — five carriers sworn to deliver the letter to the King, whatever hunts them on the road.

The Binding

The Truce & the Sealing

The letter must be re-signed by all the kingdoms every five years to keep the curse bound. Everything in the saga turns on that.

The full lore — peoples, armies, the true timeline, and the sealing explained — is in the companion volume, The Kingdoms of the Letter, on the shelf above.

Flash Tale · ~5 Minutes

The Ferryman’s Due

The dead pay the ferryman in memories. The living girl had none to spare — so she offered him one she hadn’t lived yet.

Senn had rowed the black river for three hundred years, and the rule had never bent: one memory, freely given, or you walked the bank forever. The dead paid gladly. A first kiss. A mother’s voice. The smell of rain on a harvest field. He took them all and felt none of them, the way a toll-keeper feels no weight in other men’s coins.

The girl was alive. That happened sometimes — the grieving, the curious, the ones who had followed a coffin too far. She stood on the far bank with empty hands and said, “I have nothing yet. Everything I remember belongs to people who are still using it.”

“Then you stay,” Senn said.

“I’ll pay you forward,” she said. “The best day of my life. The one that hasn’t happened. When it comes, it’s yours — I’ll live it and not keep it. You’ll have it whole, and I’ll have the shape of it and nothing inside.”

It was against every rule he had. He rowed her across anyway, because in three hundred years no one had ever offered him the future, and a ferryman, like anyone else, can be bought with novelty.

He waited. Years moved on the far bank the way weather moves. Then one evening the river itself went quiet, and a warmth crossed the water that he had not felt since he had a name — a wedding morning, a child asleep against a shoulder, an old house full of lamplight, all of it arriving at once, all of it his, all of it hers and gone from her in the same instant.

He sits in his boat still. The dead offer their kisses and their harvest fields, and he waves them through without payment, one and all. He is saving room. He does not expect the future to owe him anything twice — but if the river ever goes quiet again, he intends to be ready.

Flash Tale · ~5 Minutes

The Ninth Bell

Eight bells hung in the tower to warn the town. The ninth was cast in secret — and it did not ring for the living.

The town of Brackenholme had eight bells: one for fire, one for flood, one for the fleet coming home, and five for the smaller griefs. Master founder Ansel was paid to cast a ninth, and he was paid in the old way — half in silver, half in silence. No one was to ask what it was for.

He cast it from the metal of the drowned church at the harbour mouth, which had gone down with its own bell still tolling, forty years before. Sailors said on certain tides you could hear it under the water, keeping time for a congregation of fish. Ansel said nothing. He poured, and cooled, and polished, and hung the ninth bell in the dark of the tower where no rope reached it.

“Who rings a bell with no rope?” his apprentice asked.

“The occasion rings it,” Ansel said.

The occasion came in the third winter, when the ice took eleven ships in a single night and the town stood on the harbour wall listening to men die within earshot, too far to reach. At midnight, with no hand near it, the ninth bell sounded — low, green, patient — and on the black water the lights began to move. Eleven ships’ worth of the drowned stood up out of the ice and walked home across the harbour, leaving wet footprints on the frozen shore, and took their places at their own tables, and would not speak, and would not leave.

They are there still, most of them. The town has learned to set the extra plates without being asked. And Ansel, who is very old now, tells his apprentice’s apprentice the only useful thing he knows about his trade: a bell is not finished when it can ring. It is finished when you know what it will answer.

The Cartographer of Lost Roads

He was hired to erase a road from every map in the kingdom. Being a thorough man, he walked it first.

The commission came sealed, with money enough to buy a small house: find the road to Aldermere on every chart, atlas, and itinerary in the royal archive, and remove it. Scrape the ink. Burn the plates. The road was to have never existed.

Mapp was the best cartographer in the capital precisely because he finished things, so before he erased the road he did what no one had thought to forbid: he walked it, to confirm what he was destroying. It took four days through country that grew quieter by the mile, where the signposts faced away from him and the milestone numbers counted down instead of up.

Aldermere was a village of perhaps two hundred souls, prosperous and ordinary, except that its people looked at his map-case the way other folk look at a loaded crossbow. The elder heard him out by the well and was not surprised. “Every generation they send one of you,” she said. “The kingdom keeps remembering us, and we keep paying to be forgotten. We are taxed in the king’s ledgers as a garrison town. We send grain for soldiers who do not exist, to a war three valleys off. It is a good arrangement. The day the road is found by the wrong eyes, the tax men come in person — and the recruiting men behind them.”

Mapp scraped the road from forty-one maps. He burned the plates. He did the finest work of his life making a real place into a rumour, and the archive paid him the rest of the house money without a question.

Only one copy remains, and it is not on paper. On quiet nights in the capital, the kingdom’s best cartographer walks the four days north in his sleep — past the turned signposts, down the counting milestones — and wakes with his boots wet from a road that does not exist, in a village that is very careful to keep it that way.

The Prompt Forge — For Writers

One prompt, drawn at random, whenever the page goes blank. Story sparks, characters, and worldbuilding — take it, write the thing, and it’s yours.

Story Spark

A truce must be re-signed every five years to keep an old curse bound. This year, one of the signatories arrives — and refuses to say why his shadow is missing.

Worldbuilding

Invent a kingdom whose whole economy runs on one strange export — and decide what its neighbours would go to war to steal.

Character

Write the villain’s childhood best friend, who still sets a place for them at the table and isn’t wrong to.

Story Spark

The letter your hero is carrying was written by the person they’re delivering it to kill. They don’t know. The letter does.

The Name Forge — Who Are You in the Kingdoms?

Every carrier, captain, and harbour town in the saga needed a name before it needed a fate. Draw one from the forge — a character to write, or a place to send them — and it’s yours to keep.

Character Name

Corvin Ash

A Karsk iron-name; the Ash line has kept the Stone Pass tolls for six generations.

Which of the Five Seals Are You?

Five carriers took the letter out of the capital. Five questions stand between you and the road — answer honestly, and find out which of the Five you’d have been.

Dark Words — Sayings of the Kingdoms

Grim little truths, collected from signing halls, harbour walls, and the mouths of people who carried the letter. Take the one that follows you home.

Every truce is a war taking a breath.
A saying of the signing hall
The dead do not want vengeance. The dead want company — and they are patient.
Attributed to Sella, village elder
A king’s shadow is the first thing he sells, and the last thing he misses.
A shrine scribe’s margin note
We carried the letter across the world. Nobody ever asked what the letter was carrying.
Kael, of the Five Seals
Count the ships at dawn. Then count their shadows. Pray the numbers match.
A Morvane harbour saying
Mercy is a rich man’s oath. The poor swear by the gate holding.
A Brannock rider’s proverb
She never comes in person. She watches — through every shadow she ever bought.
Of the Witch Queen
The grave is the only court where kings and carriers get the same hearing.
Capital gallows humour

About the Author

Cody Mathew writes dark epic fantasy: sacred letters and broken truces, hunters who come up just short, and kingdoms whose wars are never quite the wars they seem. The Letter of Kingdom trilogy is complete, its world book stands beside it, and a second trilogy — The Seventh Kingdom — is on its way. Nightvellum is where all of it lives.
