Elara Voss, an archival historian in the neon-drenched megalopolis of New Polaxis, harbored an irrational but paralytic dread of darkness. It was an atavistic reflex, she knew, a remnant of the sealed blackout bunker where she had spent six years as a child during the Crowning Storms. Her colleagues dismissed it as a personal quirk, but for her, darkness was not the mere absence of light; it was an animate, predatory presence. This phobia made her an anomaly among the vault-divers who routinely plumbed the city's forgotten substructures.
Her current assignment, however, forced a confrontation with this primordial fear. The city council commissioned a chronicle of the "Dragon of the Vault-City," a legendary automaton said to have guarded the geothermal catacombs of the First Renewal era. According to fragmentary data, the Dragon was a colossal, fire-breathing sentinel built to protect the city's last clean energy reserves from scavenger clans. Historians had long debated whether the creature was myth or machine, but all accounts agreed on one unsettling detail: it lived in total darkness.
