Commander Aiko Reyes arrives at Leviathan-Bay, a sprawling under-ice algae farm on Europa, to investigate a case of espionage involving a quantum-entanglement drive schematic. The farm is a bustling hub of activity, with the scent of recycled air and the flicker of neon lights casting an eerie glow on the ice walls. The clang of ore lifts echoes through the corridors, creating a symphony of industrial sounds.

This fragment, a complex algorithm laced with unfamiliar code, raises more questions than answers, hinting at a deeper conspiracy at play.

At sunrise in Valencia, Inspector Juan Ovieda is called to La Lonja de la Seda, where the body of Blanca Ferrán, a young archivist tied to the Generalitat’s heritage projects, lies beneath the coiling stone pillars. Sparse evidence surfaces: a smeared orange oil scent, a salt-crusted scuff, esparto fibers, a tampered camera feed, and a missing phone.

The chapter closes on Juan’s uncertainty as he wonders what the artifact is and who planted it.

Barbra Dender flies to the remote island of Socotra, hungry for an untouristed mystery and a new story for her glass cabinet of artifacts. She takes a whitewashed rental in Hadibu and explores the markets and highlands, where dragon’s blood trees hum in the wind and shattered glass bottles embedded in rock sing a note she cannot explain. An elder hints at a centuries-kept secret—the Dragon’s Blood Covenant—and warns that families guard it fiercely, even as a copper coin and a vial of resin are left at her door with a cryptic line: “Look where trees drink the sea.” A teacher translates a scrap of writing referencing a cave that sings before the monsoon, and night experiments with wind and bottles reveal a coastal blowhole. At dawn, the receding tide exposes a fissure aligned by the markings on the coin, giving Barbra her first concrete clue: a sea cave near Qalansiyah where the trees nearly touch the surf. Just as she steps toward it, someone behind her speaks her name, setting up the next stage of her seven-chapter quest to earn trust, unlock a guarded legacy, and uncover a secret instrument of winds that families have kept hidden for centuries.
