When the continents slipped beneath the waves, humanity chose not salvation but elevation.
Megastructures rose from the ocean, dividing the world by access tiers: below salt-choked darkness and rusting docks; above neon-lit residential sectors; higher still corporate skies untouched by the tide.

Here, elevators matter more than roads, and status is measured in meters above sea level.
Sea Level Zero is not a catastrophe. It’s a new point of origin.
