Beyond the arcology's walls, the Thames Barrier Cities sprawled like bloated sentinels along the flooded estuary, their massive floodgates groaning under the weight of relentless waves. Salt spray mingled with the fog, creating a haze that blurred the line between sea and sky, and Elara could almost taste the brine on her tongue as she imagined venturing out—though few did without Sovereign approval. These were the outposts of Britannia Prime, retrofitted relics from the 20th century now augmented with anti-grav stabilizers and laser defenses, housing the laborers who maintained the barriers against the encroaching ocean.
In her workstation at the Data Sift Sector, Elara sank into her gel-chair, the material molding to her form with a sticky embrace. Screens bloomed around her in a holographic cocoon, data streams flowing like luminescent rivers: population metrics, weather anomalies, thought-pattern analyses harvested from millions of Mandate Chips. The air here was drier, filtered through HEPA vents that whispered constantly, but it carried the faint, acrid scent of overheating circuits—a reminder that even in this digital sanctuary, decay lurked.
Her fingers danced over the interface, neural links amplifying her speed until her mind blurred with the code. But that whisper from earlier lingered, a phantom itch in her cortex. She risked a query, masking it as routine maintenance: "Anomaly search—undercroft references." The system hesitated, a microsecond delay that felt like an eternity, then spat back fragments: old blueprints of Edinburgh's subterranean networks, whispers of pre-Flood rebellions. Elara's breath caught, the room's chill seeping into her skin as if the Mandate itself watched her.
A colleague, Marcus, leaned over, his breath hot and coffee-soured. "Kane, you look like you've seen a ghost. Quota's tight today—Sovereign's pushing for predictive purges." His eyes darted, the Mandate's influence making every conversation a potential trap. Elara nodded, forcing a smile that didn't reach her eyes, while inside, turmoil churned like the Thames' turbulent waters.
As the shift dragged on, the building trembled— a minor quake from the unstable foundations below the flood line. Alarms blared, red lights pulsing like blood through veins, and for a moment, the holograms flickered. In that glitch, Elara saw it: a hidden message embedded in the code, coordinates pointing north. Her heart pounded, syncing with the barrier's distant groans, as if the city itself urged her to flee.
