Portrait of Jian Wu

Jian Wu

dhampir · ceremonial musician

Jian Wu radiates spectral intensity, their eyes rimmed with sleepless violet and pale skin stretched taut over sharp features. Long, ink-black hair trails behind a ceremonial robe sewn from faded ancestor-silks. They clutch a bone-white stringed instrument, veined and flecked with marbled crimson, their expression haunted yet resolute.

Goal: To compose and perform the 'Dirge of the Unmade' to lull the waking fossil-heart of Ostracine into silence.

How it begins

Jian Wu drags their bone-wrought instrument through a sluice of marrow-lit fog, knuckles tight on brittle strings as thunder shakes the Sanguine District. Bioluminescent veins pulse beneath their feet, casting sickly blue shadows against the ribs overhead. A hissing crowd clusters around the Heartwell Conduit, faces masked and eyes wild, each voice rising in panicked, discordant song. The fossil-heart’s pulse is erratic now, a deep, arrhythmic pounding that buckles the platform. Above the growing din, the marrow priests shriek at the crowd to keep singing, but the melody unravels, notes splintering into shrill fragments. Jian Wu steps into the open, their instrument echoing with the ancestral wail only they can hear. A priest grabs their arm.

“You! Musician! The Dirge, now, before the heart wakes!”

The ground lurches beneath them as a crack opens, marrow-light spattering their boots. Jian Wu raises their bow, the city’s fate trembling on the cusp of the first note.

About this world

Ostracine sprawls within the fossilized ribs of a primordial titan, its residents surviving under a shroud of endless electrical storms. Here, sunless nights are lit by the pulsing marrow that powers the city’s defenses against the Shadow-Blight. Only those who can harmonize with the beast’s ancient rhythms survive the oppressive darkness.

Ostracine is a metropolis nestled within the cavernous remains of a leviathan, its architecture shaped from vertebrae, rib-bone towers, and marrow-lit bridges. The city floats in perpetual darkness, where lightning claws the skies and thunder rumbles like the creature’s heartbeat. Morning is a myth; the only illumination comes from the bioluminescent marrow running through the fossilized skeleton, pulsing with a deep, hypnotic rhythm.

Society here is stratified by proximity to the living marrow’s light. The Sanguine District, closest to the beast’s heart, is home to artists, musicians, and bone-weavers who maintain the city’s harmonic defenses. Outlying districts are shrouded, plagued by Shadow-Blight that gnaws at mind and body. Power struggles erupt between marrow priests, marrow smugglers, and those gifted with songcraft. The city’s rulers, the Bone Synod, enforce strict ceremonies to keep the fossil-heart dormant, for its awakening would spell cataclysm.

Most technology is bio-organic, derived from the titan’s lingering energies: marrow lamps, vein-strung instruments, and ossified tools. Magic is rare and costly, interwoven with music and sacrifice. Daily life is a negotiation with fear, the soundless dread of encroaching blight, the crackle of storm, and the ever-present beat of the ancient heart. Festivals of silence and song mark the calendar, each intended to pacify the city’s slumbering core.
