The mysterious crystal world, Atris. It is a world where memories and emotions from the modern world have taken form. Over time, vague concepts became crystals, forming various gemstones that make up Atris. And the beings born from these crystals, the Dragons, lived peacefully without humans knowing of them—or so it was thought.
