The River of Liquid Light

Having mastered the art of harmonizing memories, the Gardeners faced a new frontier: the purely imagined. It began not with a memory, but with a dream. A young Gardener named Elia shared a vision of a river that flowed not with water, but with liquid light, its banks lined with crystalline trees that chimed with the wind. It was a sensation no one had ever felt, a memory of a thing that had never been. For the first time, they were not just remembering their world into existence; they were dreaming it.
