In the year 2143, Earth is unrecognizable. Centuries of environmental neglect have pushed humanity to the brink, and technology has become both salvation and curse. Cities float above an uninhabitable, toxic landscape, held up by shimmering towers of neon and glass. Society is split between those who live in luxury within these airborne sanctuaries, known as the Ascended, and those who remain below, surviving in the “Veil,” the barren ground world that humanity abandoned long ago.

One night, as the sky above the Veil turns an unnatural shade of red, a message is broadcast to every device across both worlds. It’s garbled, but the words “Eden Protocol” are clear, and it triggers a ripple of panic. The protocol is a fabled last-resort measure said to have been designed in the early days of climate collapse to restore Earth to its natural state. No one has been able to confirm if it truly exists — or if it’s a myth.
