Kethra Almanac — Read Me First: Spine and Status#

Approved 19 September 2026 • drafted 18 September 2026 • Written by Claude at Briana's request, using the almanac structure she supplied

This folder answers every section of Briana's almanac structure for the planet Kethra (called Selenne in the capital), and then gives a full country almanac for its capital nation, the Caldren Crown.

This document is the spine. Every number, name and date the chapters rely on is fixed here first. If the spine and a chapter ever disagree, the spine is correct and the chapter needs fixing.

How to read the status of anything#

• CANON: approved by Briana. On 19 September 2026 she approved the whole almanac at once (the Almanac Approval Decision). The table below lists that decision and the points she approved one by one.
• Still open: the few questions the Almanac Approval Decision lists (some left to Briana, three given to Whisperling), and the in-world mysteries the chapters mark (open) on purpose.
• Anything added after 19 September 2026 is a PROPOSAL until Briana approves it. (Before that day everything outside the table was a proposal. Each file keeps its old status line, headed "Status before approval", for the record.)
• A proposal that Briana rejects should be struck out, not quietly rewritten, so that the record stays honest.

What is already canon#

The spine (approved with the whole almanac, 19 September 2026)#

S1. Deep time and the present#

S2. The planet#

S3. Geography#

The Stair. Warm eras raise the seas and cool ones lower them, while Calathe's southern coast slowly rises. The result is a staircase of raised beaches: bands of old shoreline that climb the coasts like steps. The youngest step, from the last hot era, is about 12 m up; the oldest in the Thess estuary are about 140 m up. The Founders built on the Stair. Aletheia, the capital, stands on it. The coming hot era will slowly flood the lowest steps again, with sea level rising about 0.3 m per century now and accelerating.

The Line. The equator, running through the Girdle Sea. It separates the northern heartlands, which say "Selenne", from the southern frontier, which says "Kethra". To "cross the Line" means to go south, or to make a choice that cannot be undone. *(What the book's title means is not settled here. Briana, 19 September 2026: "It's the line between empires." Whisperling, please make a determination and bring Briana the result for approval.)*

S4. Humanity off the planet#

• Light delay: a signal takes about 7 hours each way between Kethra and the Cinderbelt. Every conversation with the belt is a letter, not a call.
• Travel: fusion torch-ships reach the belt in weeks to months.
• No faster-than-light travel. It was lost (see S5), so humanity cannot leave the system.

S5. How humanity came here#

1. Earth-of-the-songs. The songs hold no history of Earth. They hold fragments: a green world under one moon, its creatures and old gods, the Leaving, and the Crossing. Why the ancestors left is lost. The songs say only that they saw something coming and went before it came. Nothing in any song names or describes what they saw. *(Why the ancestors left is not settled for the author either, and must be told without settling the protected mystery of how Earth became the Hive's home. Whisperling, please make a determination and bring Briana the result for approval.)*
2. The Crossing. The ancestors crossed by a means the songs call the Long Door. How it worked was lost in the Silence. Seven ships set out; three reached Kethra: the Patience, the Covenant and the Lodestar. They carried about 214,000 people, most of them in cold sleep, along with seed stocks, embryo banks and Earth soil cultures.
3. The Forgetting. On landing, the Founders sealed every navigation record and swore the Oath of the Unmapped: no one would ever seek Earth, so that whatever they fled could never follow a path back. The records were sealed, not destroyed. They were lost over the following centuries, as the Founders' data-stores failed during the Silence and the last people trained to read them died. Whether any sealed fragment survives, perhaps in Ilyr, is rumour and an open question. The Oath is the oldest law on Kethra and the root of its deepest taboo.
4. Landfall, AL 0. The ships came down on the southern coast of Calathe, at the place still called Landfall.
5. The Gift. The Founders engineered a gut flora that lets humans partly digest processed native foods. It passes from mother to child.
6. The Silence, AL 41–about 400. The ships' fabricators failed. The Grey Cough, a mutated Earth virus, swept the settlements from AL 44 to 61. The population fell to about 58,000 by AL 120. The knowledge behind the Long Door was lost, along with most written records. The songs survived, kept by the first song-keepers, the origin of the Cantorate.

S6. Eras (full history in Chapter IV and the country almanac)#

S7. Where the approved factions sit on Kethra (proposal)#

These are native Kethran institutions with Kethran names. They are not inherited from songs.

| Concord Fleet | Not yet formed in AL 2314. In the saga, it is the joint fleet raised when alien contact comes, in era 2. Its seed may be Homeguard Command's small orbital arm. Coalition politics over command and contributions follow the register. |

Not placed on Kethra: the Varkhesh, Orravan Empire, Ithryx, Helion and Distant Systems factions, Crossgate Exchange, Hollow Compact, Wayfarer Exchange, Farwatch Service and Noetic Directorate. Some may enter in later eras of the saga (alien contact, expansion, the fracture, the Reckoning). Their casting is Briana's to decide, except one question she gave to Whisperling on 19 September 2026: which faction is the "alien empire" of sagas 1–2. Whisperling, please make a determination and bring Briana the result for approval.

S8. Technology in the present day#

• Frames. Piloted fighting and working machines, the VectorZ machines. The law of the Frame Accord requires a human hand in every frame: "No frame without a hand." This dates from the Iron Winter.
• Energy. Fusion power, thorium fission and tidal power.
• Space. Fusion torch-ships within the system. Orbital spin-habitats.
• No faster-than-light travel. No outward signalling. The Quiet Sky Accord limits powerful broadcasts aimed out of the system.
• The Mending Accord (AL 2163), called the Mending Ban in everyday speech. Heritable human genetic editing is banned. Therapies that are not inherited are licensed.
• Listeners. Ilyr trains a small number of "Listeners" using Founder neural technology. Whether their abilities are real psionics is an open question.

S9. The Caldren Crown in brief (full detail in the country almanac)#

• Area: 5.9 million km²
• Population: 214.3 million
• Capital: Aletheia, metropolitan population 11.2 million
• Government: constitutional monarchy. The current monarch is Elisande II of House Halden, reigning since AL 2289.
• Currency: the crown (Cr), divided into 100 marks
• Religion: the state church is the Cantorate, the Church of the Song
• Motto: Keep the Song

Guidance for AI actors (applies to every chapter)#

1. Names mark origin.
   • Capital people and officials say Selenne, Theia, Hyperion, Pandia, Ersa, Kronos, Notia.
   • Frontier people say Kethra, Sól, Surtr, Máni, Hati, Ymir, Eldvang.
   • Choosing the other side's name is a deliberate act: a sneer, a sign of respect, or a person who has moved.
2. Nobody knows where Earth is. Nobody may try to find out. Merely suggesting it is shocking.
3. The songs are not history. They hold fragments: a green world, the Leaving, the Crossing, the Founders' warning. Characters treat them as scripture, poetry or unreliable memory, depending on who they are.
4. Nobody on Kethra has heard of the Varkhesh. There is no Kethran word for them. The Founders' warning names nothing; popular imagination calls it "the Dark that listens". Never connect the Dark to anything specific. How Earth became the Varkhesh Hive's home is a protected mystery, and no character, scene or document may hint at an answer.
5. The red nights are getting brighter. Everyone over 40 has noticed. What it means is a political and religious fault line.
6. Earth-descended food is life. Most native plants and animals are useless or dangerous to eat. Farmland is precious; the Wild is vast.
7. The almanac is approved (19 September 2026), so what it says is fact in play. Anything added later is a proposal until Briana approves it. Where a chapter marks something (open), do not invent an answer in a scene; flag it instead.

Files in this almanac#

Name checks for new names in this almanac#

These are informal checks against well-known fiction and games; they are not trademark clearance.

• Kronos is used for the Klingon homeworld in English-language Star Trek material.
• Ymir is a moon of Saturn.
• Aletheia is a Greek word for "truth" and has been used in some minor works.
• Calathe resembles Calathea, a genus of houseplants.
• Nifl echoes Niflheim in Norse myth. This is deliberate: it is the frontier's name.

No prominent clashes were found for Oreth, Aelos, Notia, Eldvang, Vardenhold, Ilyrion or Saltline.
