Princess Lyra floated in the observation dome of the starship Aethelgard, her fingers tracing the cold glass as she watched the nebulae bloom like ink in water. The ship hummed a lullaby of quantum drives and recycled air, a constant reminder that she was billions of miles from any planetary soil. Her daily routine—a meticulous schedule of hydroponic gardening, stellar cartography, and diplomatic correspondence—had been disrupted by a singular, nagging absence: her mother's heirloom locket, a tiny sphere of compressed starlight, was missing. It was not merely a trinket; it was the last physical artifact from a world that had been swallowed by a supernova, and its loss felt like a second death.
Lyra had retraced her steps through the ship's labyrinthine corridors, from the botanical bay where she had pruned the oxygen-producing ferns to the communications deck where she had drafted a treaty with the silicon-based lifeforms of Kepler-442b. Each location yielded nothing but the sterile gleam of polished alloy and the faint scent of ozone. She interrogated the ship's AI, a disembodied voice named Virgil, who reported with infuriating calm that no anomalous object had been logged in the past seventy-two hours. The locket, it seemed, had simply evaporated—a possibility that Lyra, with her rigorous scientific training, refused to entertain.
