Anya always felt a twinge of guilt as she gazed out from her balcony at the sprawling metropolis of the Green City. It was a marvel of technology, a bubble of perfection in a world that had succumbed to chaos. The city's dome shimmered in the sunlight, a barrier that kept the harsh reality at bay and maintained an eternal spring within.

She walked the streets lined with lush greenery, where autonomous vehicles glided silently on the solar-powered tracks. The air was always fresh, recycled and purified, devoid of the pollutants that choked the world outside. People moved about leisurely, their faces content, their lives untouched by the scarcity that plagued the rest of humanity.

But Anya knew that this utopia was built on secrets and silence. The city's Council ensured that no news from the outside world filtered into their oasis. The residents, in turn, never questioned the source of their abundance. They lived in blissful ignorance, or perhaps willful blindness, to the cost of their comfort.

As she passed the grand library, a structure of glass and living vines, Anya's thoughts drifted to the world her grandparents had spoken of—a world of diversity, of seasons, of a nature that was wild and free. It was a stark contrast to the engineered beauty around her, which, for all its splendor, felt sterile and controlled.

The city had its own rhythm, a heartbeat that pulsed through the network of machines and AI that managed every aspect of life. But beneath the hum of efficiency, there was a whisper—an undercurrent of dissent that the Council tried to silence. Anya was drawn to it, like a moth to a flame, seeking the truth that lay hidden in the shadows of the Glass Oasis.
