The Vein-Split Eclipse & the Emergence of the Resonant Marrow

Celestial Body: The Thirn-Veil Moon

A tertiary moon that orbits Comhlaidir only once every 111 years, veiled in flickering auroral filaments and trailing faint harmonic emissions detectable only by resonant-sensitive species. Its surface appears cracked like marrowed bone, glowing softly with internal light — believed to be a relic of the primordial harmonics that shaped the world.

• The Transformation Event: The Vein-Split Eclipse
• Date: 3E 199
• Duration: 5 hours, 7 minutes
• Observed from: Sradag Isle only

During its rare alignment with the sun and Crystal Lake, the Thirn-Veil Moon created a total eclipse unlike any before or since. When the light faded, the tonal veins beneath the Crystal Lake began to hum audibly, vibrating with alien cadences. The subterranean tonal lattice pulsed erratically, and every living being within proximity experienced one of three phenomena:

1. The Bone-Hollowed (Hollowkin): A small percentage of inhabitants experienced the spontaneous evacuation of their skeletal mass, their bones dissolving and reforming into tonal crystal-like structures. They became lighter, more resonant, but physically fragile. Their voices echoed strangely, and they began to hear the “future tones” of possible choices. “We have become flutes for the world’s breath,” said one. Effect: New resonance-based navigation and tonal foresight. Cultural Result: Viewed as both oracles and omens. The Order later hunted many of them.
2. The Marrowbound: Others developed marrow that glowed faintly with harmonic light, allowing their blood to conduct resonance like a tuning fork. This made them extremely valuable to alchemists and resonance engineers.
3. The Dissonant-Split: A tragic transformation. Some beings had their inner harmonic core fracture in two, developing dual tonal personalities. They often lost control over their body when the secondary tone became dominant. Effect: Unstable resonance casting, memory loss, and tone-polarity shifts. Cultural Result: Feared, isolated, sometimes recruited into military tone experiments by fringe Order factions.

Origin Myth:

A Láenthelin myth claims that the Thirn-Veil Moon is the skull of the first singer, cracked and hollowed by betrayal. Each eclipse is a moment when the singer mourns the disharmony of the present world and in that mourning, fragments of truth (and curse) are released into reality.

Aftermath & Legacy:

• The Chorus of Threaded Hands developed an entire ward dedicated to "Moon-Harm afflictions."
• A secret society within The Songbound Circle known as The Lament of Veins believes the next eclipse will trigger mass resonance awakening.
• Ancient harmonic instruments once thought inert began to react violently during the eclipse. Now housed beneath protective veils and tended by the Ir-Shael.
• Since then, lunar charting has become sacred among crystal-diviners and tonal navigators, especially those tracing pre-Fracture melodies.
