In the city of Helior, the sky was not made of clouds anymore. It was made of light.
People still called it the sky because old habits were hard to kill, but the truth was simpler and stranger. Above the city floated three layers of weather domes, each one tuned by the Central Climate Spine to keep the air clean, the rain steady, and the seasons gentle. Solar rivers ran along the outer rings of the towers. Transit rails stitched the districts together. Every home had a wall screen, a nutrient kitchen, and a cradle link that could support a child from the first engineered cell to the day they learned to run across a floor.
