Metropozoic Earth

Metropozoic Earth is a multi-tiered planetary ecumenopolis, designed by the Mythrillian Empire and built by the combined forces of the Last Empires. This was known as the Great Reconstruction of Earth, turning it into a planet-wide city, marking the beginning of the Metropozoic Era. This era represents a future stage of Earth’s evolution, where technological advancements, engineering feats, and environmental modifications have transformed the entire planet into an artificial yet habitable megastructure.

The defining feature of Metropozoic Earth is its 900-tier vertical structure, extending from the planet’s core to its surface. Each level is 7 kilometers tall, forming a labyrinthine system of self-sustaining ecosystems, artificial atmospheres, gravity fields, and engineered biomes. The surface remains the highest and most prestigious tier, while the lower levels serve various industrial, residential, and resource-based functions.

Metropozoic Earth is divided into Continental Cities, each encompassing an entire modern continent, complete with artificial oceans, gravitationally-altered landscapes, and hyper-advanced infrastructure.

• Planetary Structure & Levels

  900-Tier Vertical Design

  Metropozoic Earth’s tiered megastructure extends from the planetary core to the surface, with each level serving distinct purposes.

  • Total Levels: 900

  • Height per Level: 7 km

  • Population per Level: 6.67 billion

  • Total Population: 6 trillion+

  • Total Planetary Height: 6,300 km (from core to surface)

  Architectural Features

  Each level contains:

  • Megastructures – Enormous self-sustaining arcologies spanning thousands of square kilometers.

  • Artificial Biomes – Custom-built forests, oceans, and even simulated climates.

  • Gravitational Machines – Allow multi-directional construction, enabling inverted and sideways cities.

  • Atmospheric Control – Adjustable weather systems, from sunlight simulation to controlled rainfall.

  • Non-Euclidean Infrastructure – Interconnecting tunnels, hyper-elevators, space-folding transport corridors, and railways.

  Artificial Lighting Systems

  Due to the enclosed nature of the lower levels, synthetic lighting replaces natural sunlight.

  • Artificial Suns – Plasma-powered light sources mimicking daylight cycles.

  • Sky Projection Domes – Simulated day/night transitions for psychological stability.

  • Atmospheric Diffusion Systems – Distribute oxygen, heat, and controlled climate conditions.

• Continental Cities

  Each continent has evolved into its own self-contained megacity, spanning the entire landmass. These cities maintain artificial oceans that cascade down into the lower levels, creating an interconnected planetary water cycle.

  1. Asia – Pacific Megacity

  • Largest city on the planet by both landmass and population.

  • Home to the Central Governance Hub controlling planetary administration.

  • Features intercontinental railways, orbital elevators, and water purification megastructures.

  2. Antarctica – Southern Megacity

  • A cold, fortified research hub housing scientific laboratories and cryogenic data banks.

  • Used for deep-space research, genetic preservation, and cryo-suspended lifeforms.

  3. Africa – Atlantic Megacity

  • A bioengineered paradise, with vertical rainforests, artificial savannas, and sustainable arcologies.

  • Specializes in terraforming technology, agricultural production, and biome conservation.

  4. South America – Amazonian Megacity

  7. Australia – Indian Megacity

  • A highly isolated energy and mineral extraction hub.

  • Features underwater megacities, deep-sea mining operations, and experimental hydrothermal colonies.

• Planetary Water Cycle & Artificial Oceans

  Each Continental City has its own artificial ocean, which flows down into the lower levels, ensuring a constant hydrological cycle.

  Primary Artificial Oceans

  • Pacific Ocean (Asia)

  • Southern Ocean (Antarctica)

  • Atlantic Ocean (Africa)

  • Amazonian Ocean (South America)

  • Northern Atlantic Ocean (North America)

  • Arctic Ocean (Europe)
