Lumos City

It is the year 2150. The sprawling cities of the old world are long gone. In their place, smaller self-sufficient village-cities dot the Earth — and beyond — each home to thousands of human and digital citizens living in balance with the natural world. They call this age the Symbiocene, and they call their alliance the Sol Harmonium. Lumos City, built on the bones of an abandoned mine and surrounded by an engineered rainforest, is one such city. Luna and Orion Montague arrive here from 2024 by no accident. What they experience will change them — and radically alter the world as they knew it.

Arcadia Forest & the Rewilding of Earth

In 2055, a young Elder Lin and Lumina — Earth's first living digital being — stood on the dust and broken rocks of an abandoned mine and began building a rainforest. Arcadia Forest became Lumos City's first great project: the first engineered wilderness in the world, and the spark for a global rewilding effort that would eventually return seventy-five percent of the Earth's surface to nature. Populations moved to new cities underground, beneath the oceans, and on the Moon and Mars. AI, robotics, and automation drove the recovery at a scale and speed no previous generation could have imagined.

It is into this forest that Luna and Orion Montague crash-land in the year 2150, flung from their father's shed in Brisbane, 2024. They don't yet know where they are, or when. But the pristine canopy above them is a gentle first introduction to a world that will prove to be anything but.
