The Rainbow MiniWorld is a world within the rainbows of Graynor Ruins. There are colorful ribbons in it. Each stripe has its own magic. The heart of the Rainbow MiniWorld is the Seven Color Sphere which is a ball of ribbons. The sphere makes disharmony when it goes unstable, causing the ribbons to go their own ways. Furries are cat-like creatures with belled hats that reside in the Rainbow MiniWorld.
