He soon arrives in another world, called Traverse Town, where he comes upon Donald Duck and Gooft, 2 emissaries from the Disney Castle sent by King Mickey to find the owner of the Keyblade. The 3 then band together and travel to the different worlds themed after various Disney films, sealing the hearts of the world to protect them from further invasions by the Heartless.
