A companion to the Almanac of Stars

The Siren Bone Oracle

Arcadian Astrology.

Fantasy lore · Astrology · Myth & prophecy

Twelve stories. Twelve turnings. Four written in light, eight await their time.

Start here

Three signs. One doorway.

In Athea’s system, these four parts work together to form your Star Day. Each adds something different to the reading.

01 · Constellation

Who you are

Your birth date gives you a ruling constellation—the story you were born to tell.

02 · Moon phase

How you feel

Your day within the Arcadian month reveals the feeling beneath the surface.

03 · Rising sign

How you arrive

Your constellation and birth hour combine to describe what others notice first.

04 · House

Your doorway

Your day within the Arcadian month names the house all three signs came through.

For a step-by-step introduction, explore the Almanac’s Star Day guide. The full conversion chart and Rising Shift Table belong to the forthcoming books.

Together, these create the Star Day—a unique configuration that appears in the sky only once in each life, a cosmic fingerprint that reveals not destiny but tendency, not fate but inclination.
— Athea, The Rising Truth

The twelve constellations

Some stars remember. Others wait.

Four constellations already burn in Arcadia’s sky, holding stories that have happened. Eight are still unborn: prophecies waiting to become history.

The four that already burn
The Lovers
Loriven • Eternal Return • Gold, Silver, Black
Two lights circling eternally, one remembering, one forgetting—eternal testimony to Elodias and Senia's cursed devotion. Those born beneath it love so deeply that it transcends reason, time, and even death; they know certain souls on sight.
The Wanderer
Wanderis • Endless Journey • All colors shifting like aurora
Thainos's thousand-year search held in a pattern of stars, his divine essence scattered like seeds across humanity. Wanderer-born souls cannot rest; home is not a place but a state of motion, and the search itself is the answer.
The Hunter
Thornmarch • The Chase • Blood red, Ash gray, Gold of dying stars
The Bloodmarked's tragic corruption writ large across heaven—heroes become horrors in their victory. Hunter-born souls carry the terrible gift of doing what others won't for causes that matter, knowing every hunter eventually becomes the hunted.
The Dragon
Drakonis • Forbidden Knowledge • Deep purple, Stars within darkness, Bone white
The most ancient constellation, older than the gods themselves, imprisoning something that predates even them. Dragon-born souls hunger for secrets that destroy the seeker—keepers of secrets and revealers of truth, guards at doors that must stay closed.
The eight that await their time
The Awakener
Primaven • Transformation • Gold, Pale Blue
"The Awakener shall blaze when silence itself learns to speak. Words shall break from the void to find their vessels, and in their hearing, the unmaking begins."
The Garden
Verdanis • Paradise • Every green that exists, Pearl
"In the Garden's light, mortals shall either reclaim their first innocence or watch it wither beyond all recovery."
The Crown
Solmere • Sovereignty • Gold, Purple, White
"The Crown shall manifest when the true sovereign awakens to their burden. Not born to power but chosen by necessity."
The Guardians
Umbralux • Protection • Silver and Black intertwined
"The Guardians shall stand between light and shadow, and their formation shall mean that something precious enough to die for has finally been found—or is about to be lost."
The Shepherd
Goldmere • Guidance • Warm amber, Soft white
"The Shepherd's crook shall appear in stars when one must choose between saving the many or preserving the few." Not all who are led shall wish to follow.
The Storm
Stormend • Necessary Destruction • Lightning white, Thunder gray
"The Storm shall rage in heaven when the old order must be swept away. Its winds shall carry both destruction and the seeds of what comes after."
The Tower
Frostmere • Isolation • Stone gray, Ice blue
"The Tower rises in stars when one must stand alone against many, or when many unite against one. Its height shall measure the distance between earth and heaven—or the depth of the fall."
The Broken Chain
Veilmorn • Liberation • Rust and Silver
"The Broken Chain shall scatter across the sky when the oldest bond finally breaks. Freedom and catastrophe shall be one word spoken in different tongues."

If you were born under one of the eight, your constellation has not yet formed in Arcadia's sky. You carry the blueprint for stars that hunger to exist; your life becomes the myth that will one day justify their burning. This is not absence. It is potential. Your choices feed or starve your constellation's birth—living as what you are hastens it; denying your nature delays it.

The moon keeps her own calendar, independent of constellation or season. She moves through eight faces, eight ways of feeling that cycle endlessly through every soul born beneath her light or shadow. Where your constellation marks the story you were born to tell, your moon phase reveals the hidden architecture of your soul—that private self you show to no one, not even yourself.

The guide maps all 96 combinations of constellation and moon phase—the Lovers under a New Moon whose devotion operates in secret even from themselves, the Awakener under a Dark Moon who is the awakening from awakening itself—and, in The Lunar Dance, all 36 pairings of phase with phase, from two New Moons (The Secret Sharers) to the Dark Moon meeting its own kind.

Twelve houses emerged from the marriage of earth and sky, each governing a different realm of mortal experience. The house is fixed by the day of the month within your constellation's reign: it does not move with the hour, and it does not follow from your rising sign—the house is the doorway the date opened, and the date opens it for everyone born that day. Athea is blunt about what they are: not fixed addresses but rotating possessions. We die through all twelve houses every month, and are reborn through them.

The houses gather into trinities—Fire houses of Being (Threshold, Crucible, Horizon), Earth houses of Having (Foundation, Ritual, Throne), Air houses of Relating (Messenger, Eternal Dance, Community) and Water houses of Feeling (Sanctuary, Abyss, Void Temple)—and into doors, rooms and corridors: souls who came through a door make visible marks on the world and begin things others must finish; those who came through a room consolidate and preserve; those who came through a corridor are always partway somewhere.

Six skies · finding your rising sign
Birth hours and the skies of Arcadia
Hour of birthSky ascendantWhat that sky wants
00:00 – 03:59The Crimson TundraSouls who arrive with authority already attached and distance already established
04:00 – 07:59The Azure ExpanseCatalysts—those who move conversations, people, situations that had settled and should not have
08:00 – 11:59SolaraSouls who arrive warm and arrive certain; things grow near them that had no business growing
12:00 – 15:59The Verdant VeilThose who carry something the rest of us lost. People assume they know things; people are usually right
16:00 – 19:59KavakRevolutionaries and hermits, who are more alike than either would admit
20:00 – 23:59The Godscarred WastesSouls looked at differently, whose bearing suggests they have already seen the ending

Why are two souls born on the same day not the same soul? The answer is the hour. The world turns while you are being born, and six times in a day the sky over Arcadia changes hands. Your rising sign does not tell you where you were born. It tells you which country's heaven was awake—"the least true thing about you and the first thing anyone learns."

Your constellation's row meets that region's column in the Rising Shift Table—twelve constellations by six skies, seventy-two cells—and where they meet is your rising. There is no arithmetic; each region pulls toward what it loves. Some skies reinforce a constellation instead of shifting it, so that you rise as what you already are and the world gets no warning. Others produce the interesting cases: the Hunter born in the Veil's hours rises as the Dragon, the hunt gone underground and arriving as ancient patience.

The twelve rising signs, in a sentence

Guardians Rising
"I am the wall between chaos and those I protect."
Wanderer Rising
"I am already halfway gone."
Shepherd Rising
"Let me guide you home."
Hunter Rising
"I have already marked you as prey or predator."
Storm Rising
"I am the necessary destruction."

The Celestial Concordance

Where different natures meet.

The guide explores 78 constellation pairings, from harmony to opposition. These readings explore how people interact, rather than deciding whom they should love.

Awakener + Storm
Perfect Harmony
Revolution meets revelation in a union that reshapes reality itself. When Awakener and Storm unite, old gods tremble and new ages dawn.
Wanderer + Dragon
Perfect Harmony
Endless journeys guarding infinite mysteries—the eternal spiral of seeker and secret, question and answer that leads only to deeper questions.
Wanderer + Tower
Cosmic Opposition
Ultimate motion meets absolute stillness—the eternal river meeting the mountain. Harmony requires discovering that the mountain shapes the river's course while the river carves the mountain's face.
The six kinds of connection
  • Perfect Harmony
  • Explosive Passion
  • Challenging Growth
  • Difficult Lessons
  • Cosmic Opposition
  • Mirror Souls · two people sharing one sign
The stars incline, they do not compel. Even the most opposing natures might discover a third path, writing new constellations in their wake.
