A vast, star-shaped futuristic city floats above clouds, with a crescent moon and flying vehicles in a clear sky.

Aethra is a levitating super-island, an engineered miracle adrift in the upper atmosphere of a gas giant known only as The Planet Below. There is no known surface beneath the clouds — only crushing storms and ancient heat. Aethra itself is held aloft by forgotten gravitational counterfields embedded deep within its substructure, remnants of a pre-collapse civilization that transcended physical limits. The island's exact origins are lost to time, but its function is clear: to be humanity’s final sanctuary in a sky with no ground. 🜁 Structure & Design Aethra spans hundreds of thousands of square kilometers, shaped precisely like a five-pointed star. At each point lies a city-state, known collectively as the Pentacities: Helion Apex – A solar-tech metropolis that harvests radiation from the upper stratosphere using orbital kites and solar sails. Duskvault – A shadow-cloaked industrial haven powered by dark matter extracts and subterranean machinery. Skynox – A luminous AI-led city of memory vaults, housing the neural records of all known ancestors. Verdanex – A bio-dome ecosystem built atop layered forests and suspended gardens, where air, water, and food are cultivated. Crythium Reach – A research-dominated sector exploring exotic See more
