About

Beyond the reach of any nation, on the high seas, lies Ark Lagoon—a massive semi-submersible mega-float complex that artificially recreates emerald-green shallows. ### City Overview Rising just 12 meters above the sea, geometric structures made of glass and white reinforced carbon are linked like a small atoll surrounding a massive coral reef. It is a luxury city for the global ultra-wealthy, entrepreneurs, and those seeking escape from the constraints of land. ### City Structure and Lifestyle - **Layer 1 (Upper Lagoon):** An area featuring overwater villas, private beaches, and Michelin-starred restaurants. In the artificial inlets, where waves and temperatures are kept constant 24/7, guests can enjoy diving and windsurfing. - **Layer 2 (Under Sea):** Residential and commercial districts submerged beneath the surface. Enclosed by autonomous acrylic walls, guest rooms and dining areas offer views of natural tropical fish and submerged ruins of the old world. The underwater spa area, themed around "Silent Luxury," is a popular destination. - **Foundation Area (Core Engine):** The city's ballast section extending to a depth of 100 meters. It fully automates cooling systems via deep-sea water intake, desalination plants, and wave/geothermal power generation (sourced from seabed volcanoes). ### Main Facilities - **Grand Blue Plaza:** A 360-degree glass-walled main hall located 20 meters underwater. At night, it transforms into a club where bioluminescent microorganisms and projection mapping intersect. - **Solaris Tower:** The only skyscraper rising from the city center. It serves as a hub for solar and wind energy collection and is the headquarters for the city's self-governing body, the Ark Council. ### Tourist Spots: Solaris Grand A 5-kilometer circular glass deck covering the outer edge of the city. Designed to be nearly level with the sea surface, it gives visitors the sensation of walking on water. - **Sunset Terrace:** At dusk, parts of the deck submerge into the sea, transforming into a stunning bar area where waves lap at your feet. - **Drone Skyride:** A departure point for sightseeing activities where small air taxis provide a panoramic view of the entire city from above. ### Nature Areas **Neo-Atoll (Artificial Bio-Lagoon)** A massive artificial ecosystem sanctuary, 1 kilometer in diameter, located in the center of the mega-float. - **Micro Jungle:** A dome-shaped vegetation area recreating a tropical rainforest climate. It is lush with genetically modified plants that glow faintly at night. - **Symbiotic Coral Reef:** A protected area where fast-growing reinforced corals and endangered marine species are bred. Entry is permitted only via guided diving tours. **Aquarium Area: Abyss Panorama (Deep Sea Experience)** Unlike typical aquariums, this is a next-generation "wall-less" facility set in the subsea section (30–50 meters deep). - **Reverse Aquarium:** Humans enter reinforced acrylic tubes to observe large wild marine life (sharks, mantas, whales, etc.) swimming freely in the ocean outside. - **Deep Sea Projection Theater:** Cameras and sonar are permanently stationed in the deep sea below the facility. Creatures from 1,000 meters deep, usually unseen, are recreated as ultra-high-definition holograms. ### Cyber Data Dome (Seabed Data Center & Exhibition Hall) Part of a cutting-edge high-speed data center cooled by seawater is open to the public, serving as an interactive digital art space that visualizes the city's entire system. - **Data Fish Mapping:** Visualizes the city's cryptocurrency transactions and communication data as colorful "light fish." Visitors can observe and interact with them as they swim in schools inside the dome. - **Nereus Core (AI Dialogue Room):** The main server room for Nereus, the city's marine conservation AI. Visitors can talk directly with a 3D holographic AI avatar or consult it for data analysis. ### Area Concept: Core Machinery (Layer 0) The city's ballast and power area extending to a depth of 100 meters. This massive space, where inorganic generators and cooling pipes are exposed, has been "gamified" by the city's maintenance AI and entertainment corporations, opening it up as a cyber-industrial district for residents and tourists. ### Key Areas & Facilities - **Real Dungeon: Engine Room 3 (Former Drainage Plant)** An experience facility where city maintenance work itself is turned into an AR (Augmented Reality) game. Participants wear gravity suits and laser tools to clear out AI-generated "virus organisms" and "leak monsters" while performing actual pipe cleaning and inspection missions. Rewards are paid in cryptocurrency based on performance. - **Pipe Racers (Geothermal Pipeline Circuit)** A circuit for high-speed hoverbikes built in the gaps between massive cooling pipes for geothermal power generation. Racers blast through dangerous areas where steam vents and giant fans spin at speeds up to 300 km/h. Sensors lining the vehicle and track walls ensure safety by instantly switching to a simulation if a crash occurs. - **Gaming Control Tower (Central Control Observation Area)** A giant monitor room that visualizes city energy distribution and desalination loads like a real-time simulation game screen. Visitors can take on the role of "City Governor" for 10 minutes to solve optimization puzzles for actual city resources. High scores can earn stay vouchers for overwater villas or access to exclusive VIP areas. - **Survival Ballast (Enclosed PvP Field)** A zero-gravity and submersible battle arena repurposed from the massive ballast tanks used to adjust the city's buoyancy. Seawater is pumped into the tanks at set intervals, causing the field to change constantly. Players engage in survival matches using non-lethal paint guns and anchor guns.
