Echo Nexus buzzes as Lumina City’s restless transit hub, a neon-lit sprawl where the hum of jets and drones never fades. Anchored by the Lumina Skyhub, this district is the city’s gateway, a chaotic tangle of sleek terminals, cargo bays, and skybridges worn by years of relentless use. The Echo Spire rises above the runways, a towering comms hub where holo-screens flicker with flight schedules and ads. Cargo Bays stretch east, a cluttered maze of loading docks and warehouses where crates stack high and deals hum beneath the roar of engines.

​

      The fringes host the Driftgrid Blocks—cramped tenements and vendor stalls where airport workers and travelers crash between shifts, their lights reflecting off stained tarmac. Echo Nexus thrives on motion: pilots, riggers, and hustlers weave through crowds, chasing schedules or scores. It’s rough but alive, a worn cog in Lumina’s machine where the sky’s promise meets street-level grind. Holo-boards blare arrivals and departures, their glow cutting through the jet-fuel haze, while street musicians sync beats to the rhythm of takeoffs.

​

Gang Presence: The Savage Huns run the Cargo Bays, smuggling contraband through the Skyhub’s bustle with ruthless efficiency, but the BioPunks slip in from Undercity Slums, peddling biotech mods to travelers and workers. Their turf tussles keep Echo Nexus on edge, a noisy battleground of trade and trickery, with Zenith Corp drones hovering above, locked in a tug-of-war with QuantumNet for the Spire’s comms control.
