A city above the clouds is protected by four magical crystals. Each crystal is located behind a door guarded by angels. Three crystals have already been stolen, along with the key to their door. If evil gets its hands on the last crystal, the city will be lost. The key to the door that holds the last crystal is destroyed in battle. The fragments fly far away and land in different places on Earth. Only the guardian of the crystal is able to reunite the key. Finding the guardian and returning with the fragments is the responsibility of a small, gnome-like creature that has the power to influence time. Will he succeed and return to Cloud City?
