Sennova is a hollow planet — a geode the size of a world. Six layers from surface to core. The deeper you go, the stranger the light. Each civilization built differently because each civilization thinks differently about what light means.
SHELL
The surface. Three moons. True sunlight — and the sunwashed planes stretching ninety percent uncharted beyond the opening, Monster Hunter hostile. Two months of travel to reach Prima Sol. The world above the wound.
FRACTURE
The threshold. Where underground meets sky. Knife-thin beams of surface light cut through cracks in the planetary crust, looking less like light and more like wounds in the ceiling of the world. Lumengarde sits here — the city that belongs to everyone and no one.
BANDED GALLERIES
The Drydalis interior. Veinsclaire threading through stone in tributaries of amber-gold. The planet's deep hum vibrates at frequencies below the threshold of conscious hearing but above the threshold of biological registration. The body hears what the mind does not name. Vel'ori grow larger here. Thal'inae gather at the crystal seams in clouds of pinprick light.
INCLUSION ZONE
Contested mid-deep. Where the Father's crystal grew through the Seminara's neural pathway. Where Obsidienne lost her eye. The mineral colonization that cost her the left side of her face began here — Father's reach extending upward through the stone like a root system looking for purchase.
DRUZE
The wild deep. Ferox territory. Bioluminescent jungles underground. Crystal caverns. Bone galleries where history is written in the only medium the nature gods use. Stone-Strider territorial calls travel through the mineral substrate at the speed of geology. When the soundscape goes silent, something is hunting.
PHANTOM CORE
The deepest place. The Father. Adam's chair. The silence that doesn't answer. Four frequencies broadcast through a crystal network that threads the entire planet. Ownership. Extension. Assessment. Compliance. And a fifth — a hole where sound should be. Structural silence. The shape of what it refuses to say.
🔱 PRIMA SOL
The city descends into the earth in tiers, carved into the walls of the Caelit Hollow. At the rim, the Basilica catches the last light of day while everything below spirals into vastness. The Church sits in true sunlight. Everyone else lives in what light they can afford. Three hundred and twelve steps from street level to the Pontifical chamber. His sons climb the same stairs as everyone else. That is the point.
"The deeper tiers glowed with their own light, veinsclaire deposits threading through stone, amber and gold and soft blue-white. And the music funneled down through the city's bones — God's voice grown thin with distance."
🌊 LUMENGARDE
The threshold city. Two civilizations bolted together at the seam — brass forcing coral into straight lines, the tide dissolving the solder every night. Gondolas shaped like fish glide through water that glows from beneath. Solis townhouses shoulder against Drydalis shell-domes. Tinkari silk lanterns hang between every surface in amber and warm pink, the light pooling on the water below in soft, wavering circles. The seams show if you know where to look.
"Three years of negotiation built this. This marketplace where everyone pretended the knives in their sleeves were just for cutting bread."
🐙 THE AMBER THREAD
The Tinkari trade route that threads every settlement in the hollow like pearls on a string. Timber-frame boardwalks suspended over water channels. Dark-tiled pagoda rooflines curving above counting-house facades. Silk lanterns strung between every surface. Warmth added to cold. Commerce added to stone. Merchant-Provost Kess had his ledger out before the delegation finished descending.
"Everyone's here to negotiate, Commander. The fee applies regardless."
🪷 RADIX
The ocean city. Not built — cultivated. A reef shaped over centuries by Drydalis hands that understood the coral's growth patterns and guided them into galleries and halls and stairways that descend into the luminous water itself. Purple-blue bioluminescent ocean. Nacre flooring carrying the ocean's caustic light — rippling, shifting patterns thrown upward through the mineral surface. Scalloped edges. Organic curves. No straight lines in Radix, because the reef has never needed them.
"The city was intact. The city was occupied. The species that built to hold rebuilt what held."
⚓ CARMYR
Ward's settlement. Three habitation tiers carved into a granite shelf, connected by steel catwalks he welded himself. Crimson lotus floats on dark water — the deep's blood-flowers, roots threading through still water that reflects the Father's amber glow from below. Nobody planted them. They grow because the wound grows them. Close enough to the surface opening that night crews can hunt on the plains after dark. Far enough inside that sunlight never reaches the habitation tiers.
"The sound arrived through the fissure as a whisper carrying the smell of cold soil and dry grass and the vast, indifferent atmosphere of a world that did not know one hundred and eighty-six people lived inside its bones."
🏔️ THE SUNWASHED PLANES
Ninety percent uncharted. The surface world above the hollow. Grasslands rolling under wind. Tusked boar. Ridge-cats. Carrion hawks whose wingspan blocks the moonlight. The three sister moons — jade-green, silver-white, massive amber — and where they align, the planetary rings catch their combined glow and refract it into curtains of aurora. Green and silver and gold cascading across the dome of night. Nox is out here. Six years of walking through territory that wants him dead.
🦈 THE PHANTOM CORE
The deepest place. Where Adam sits. Where Father's four frequencies broadcast through the crystal network. The hive-mind at the bottom of the world — a presence that doesn't ask, because the absence of the question is the engine. Three thousand years of the same signal. The same ownership. The same silence that Elara spent her dissolving mind trying to translate.
🧜🏻♀️ DRYDALIS
Underground. Scaled. Bioluminescent throat-bands that broadcast emotion as color — cantellae don't lie, which means the body files every report the mouth refuses to give. Deep-readers who press their palms to crystal and hear the planet's frequency. Cannot survive sunlight. They pray at water shrines — sel'ithra a'neri, hand-to-tide — and their language follows tidal patterns, rising clauses for questions, falling for assertions. The whole language moves like water. Authority grows from skin, not from flags. The body is the banner.
"A Drydalis woman gliding through the crowd, boneless and precise, her throat-bands flickering colors he couldn't read but could feel. Half-heard music in a language his bones almost recognized."
☀️ SOLIS
Surface dwellers. Brass and steam and the Church of Sol. They worship the Artificer — an invented god — and plant sun-sigils on every vertical surface: gold on white, stamped into customs booths, cast into drainage grates, etched into lamp housings. The flag is the first sentence of every conversation, and the sentence says: we are here, and here is ours. Four layers of fabric between skin and world because that's what breeding demands. Beauty is another form of control. Prima Sol doesn't have silence. It has degrees of noise.
"Music was the only thing the Basilica gave away for free."
❤️🔥 SANGUIS
Created by the Father as missionaries — fallen shepherds designed to spread worship who fell in love with the flock instead. Bite infection. Cold hands, golden eyes that catch light and throw it back brighter. They don't have a religion; they ARE the religion. Infection is corrupted communion. Blood is sacrament. The hive is the congregation. When Eve births a fledgling, she presses her lips to their forehead and whispers welcome, and the two hundred watch with patient reverence, remembering their own transformations.
"His fingers brushed hers. Cold. Ice cold. Like touching marble in a cathedral."
🦈 FEROX-CTHON
Nature gods in bodies the planet imagined. Stag-gods, panther-hunters, jaguar-warriors with gold medallions. The planet is their goddess — a womb, a mother. Gold regalia is the mother's livery. They speak in mating calls, not theology. The Hunt is not war; the Hunt is labor — the planet's body contracting to expel infection. Indiscriminate, because the immune system doesn't check identification. Stone-Strider territorial calls travel through the mineral substrate. When the soundscape goes silent, something is hunting.
"The hollow's fauna had drawn a line somewhere above and refused to cross it."
🐙 TINKARI
Anthropomorphic merchants. Chaos-thriving. Ears angle toward interest, never flatten in fear. They calculate, file, profit. Waistcoats of organic-fiber weave stitched with tool loops and pockets at every seam, trade-guild tokens in brass and bone clustered at the collar like a merchant's medals. They love chaos the way other species love stability — because chaos creates opportunity and opportunity creates margins. The respect for the old ways and the selling of the old ways are not contradictions.
"Those amber eyes didn't blink. Didn't waver. They assessed. Catalogued. Priced."
🪸
CANTELLAE
Bioluminescent throat-bands. The Drydalis body's broadcast system — emotion rendered as color, legible to anyone trained to read it. Rose-gold for desire. Diplomatic silver for control. Grief-violet for what the mouth won't say. Citrine's have been dark for six months. The bands don't lie, which is why the darkness terrifies.
🐠
VEINSCLAIRE
Crystal. The planet's living tissue. Threads through stone in tributaries of amber-gold and soft blue-white. Base of the food web. The hollow's sun. The only material — besides Ferox themselves — that kills Sanguis. Drydalis strategic asset, Solis mining target, Tinkari commodity. The rock is the sun, and everyone is fighting over the light.
🪼
THE COMPACT
The treaty between the Solis Church and the Drydalis Sovereignty. On paper: diplomatic stewardship. In practice: you can't plant the orange tree without permission, and the yield is never yours. The first layer of the system.
🦪
THE FATHER
Hive-mind at the Phantom Core. Four frequencies broadcast through the crystal network: ownership, extension, assessment, compliance. It doesn't ask. That's the architecture. The absence of the question is the engine. Three umbilical cords: the ecology, the Drydalis, the Sanguis. All of it seeded. All of it tended.
🪷
THE HUNT
The Ferox immune response. Not war — labor. The planet's body contracting to expel infection. Seven hundred bodies moving through stone with the indifferent pressure of a mass that treats architecture as terrain. Indiscriminate. The immune system doesn't check identification.
🪸
VEL'ORI
Crystalline organisms with luminous tendrils that hang like drowned hair. Jellyfish-shaped, moth-light. Grow larger with depth — torso-sized in the deep galleries. Their membrane-flutter arrives as subsonic pulse. Go dark near predators. Their dimming is the first warning.
🌊
THAL'INAE
Living dust. Pinprick bioluminescent organisms that gather at every junction between crystal and stone. Clouds of them surge toward veinsclaire in waves. The accumulated glow gives exposed rock an ambient luminescence that pulses independently of any lamp. They follow the crystal. They like Nox.
🫧
TIDALECT
The Drydalis mother tongue. Grammar follows tidal patterns — rising clauses for questions, falling for assertions. Etched into ship prows in prayers or curses no Solis can distinguish. The whole language moves like water. Neri'thael vosce: the tide that does not return. Rameses knows the word. Rameses lives the word.
💧
SEL'ITHRA A'NERI
Hand-to-tide. Drydalis prayer. Palm to water for three seconds. The water accepts whatever the cantellae offer. No shrine required. No veinsclaire shard. The hand is the only offering the practice needs.
🫧
SEMINARA
Ruling title of Radix. Not a surname — a station. The matriarch who holds the ocean city. The veinsclaire-threaded throne in the deep gallery, the deep-reading interface that lets the Seminara press her palm to the stone and hear the planet speak.
🗡️
THE AVAR
Veinsclaire trident. Seminara ancestral weapon. Tide-splitter. Three prongs. Nox's birthright. Citrine retrieves it from Radix. The weight settles into the palm as if the palm had been carved for it.
🪻
LITHOSYNTHESIS
The hollow's photosynthesis. Veinsclaire converts geothermal heat into usable energy through its symbiont microbes. The rock is the sun. The entire underground ecology — the vel'ori, the thal'inae, the fungal forests, the crystal gardens — runs on light that never came from a star.
🌙
CONVERGENCE
Triple moon alignment. Jade-green, silver-white, massive amber. Where they align, the planetary rings catch their combined glow and refract it into curtains of aurora. Triggers thal'inae blooms, vel'ori migration, Leviathan songs. The night the sky made the gala seem small.
🦋
MOTHLINGS
Deep archivists. Beautiful dark-fae moth people. No mouths — they communicate through visuals and resonant thought. Neutral. No enemies. They care for Elara in the deep, tending the woman whose mind is dissolving while her hands keep writing. The archive endures.
🔥
THE DIMMING
Sun-worshippers hiding from the sun. When infection spreads through the Solis faithful, sunlight becomes lethal to the converted. Shuttered windows. Candlelit dinners. The faith dismantling its own light one curtain at a time.
🪼
VEL'THIRA
The blanching. When veinsclaire's symbiont microbes die, the crystal goes dark. Coral bleaching underground. The hollow's ecosystem failing at the foundation.
🦴
BONE GALLERIES
Ferox territorial archives. Ribcages as doorways. Skulls at entrances. History written in the only medium nature gods use. The deep's record-keeping — older than language, more honest than paper.
Tidalect is the Drydalis mother tongue — the language that predates the Compact, predates Common, predates everything the surface built on top of what the deep already knew. It moves like water: action before subject, the doing mattering more than who does it.
ENDEARMENTS & BLESSINGS
nox'eth
Dark-child. The name Citrine gave her son. An endearment that carries the deep's warmth — not absence of light, but the specific warmth of a place where light is grown, not given.
sira'ith
Little crystal. Obsidienne's private name for Nox. The diminutive of sira (crystal) — used for children, for precious things, for the small formations that grow in crevices where nobody is watching.
mira'ith
Little-sister. The blessing spoken before departures.
vel'itha, lume'ith, vel'itha
Softly, little-light, softly. A lullaby. The words Citrine's mother hummed before the politics came.
dari'ael nai dari'vel
Never do I drift from you. Obsidienne's oath over Nox at the naming ceremony. The deepest Tidalect commitment — the tide promising not to leave.
rith thael'ae
Stone holds deep. A blessing spoken over departures. The grandmother's prayer.
WORLD & NATURE
vel'ori
The translucent jellyfish-like organisms that drift through the hollow's galleries. Living lanterns. They dim near predators, contract near danger, and attend the dying. The reef that reads the world's mood.
thal'inae
Living dust. Pinprick bioluminescence at the crystal seams. The airborne plankton drawn to cantellae frequency. They surge toward Wendy. They scatter from the Hunt. The ecology's smallest witness.
thael'vael
The deep-voice. The planet's speech conducted through veinsclaire at frequencies below conscious hearing. The body hears what the mind does not name.
vel'karis
The slow threading. The process by which veinsclaire grows through stone — the planet's own circulatory system building capillaries through millennia of mineral deposition.
neri'thael vosce
The deep-voice. The crystal network conducting the planet's speech through stone.
a'neri siphael
Auspicious rain. The Vel-Siphae water dancers' cascading light-cords — rainfall made from light. The rain the hollow has never known, built from crystal and silk and the memory of water.
TITLES & GOVERNANCE
Seminara
Title, not surname. The ruling house of Radix. Three centuries of governance carried in the name. The matriarch IS the Seminara.
Vel-Syndic
Head of the Drydalis council. Currently Rhodonite. The governance title that predates the Compact.
Kor-Provost
Administrative title. Vesparian's rank. The bureaucrat who keeps the machinery turning.
Dyn General
Drydalis military rank. Velthorne's title at Border Garrison Twelve.
A'Seminara
The vocative. The formal invocation the L'ordo still uses because the L'ordo remembers what the Council agreed to forget.
THE SONG
thael'iri nosa vel, thael'iri nosa khem
The tide remembers what the stone forgets. A lullaby sung during communal meals in the dark. The history the checkpoints cannot confiscate because it lives in the throat. When Harren's widow sang it in the box, the children's dim cantellae flickered — the melody doing what the supplements could not.
