The tranquility of the Verdant Sanctuary was shattered when a rusted, ancient drone landed at the edge of the valley. It wasn't a Warden drone; it was a civilian model from the lower sectors. It carried a desperate message: the city's oxygen scrubbers—the machines that kept millions breathing—were failing.
Zeeshaan looked at his tools, then at the glowing silver-leafed tree. "They're suffocating, Zhuo," he said, his voice heavy with the mechanical knowledge of his father. "The city was never meant to last this long without life."
Zhuo touched the silver bark. She felt the pulse of the earth. "We can't just watch them die from our paradise. If the tree can save this valley, its seeds can save the city." They made a choice. They wouldn't hide anymore. They would return to the Iron Coast, not as fugitives, but as the last hope for a dying world.
