Maginaryworld (マージナリワール Mājinariwāru?) is the main setting of Sonic Shuffle. It is where Illumina, the Forcejewels and the Precioustone reside. It is the dream world created from the dreams of people in other dimensions through the power of the Preciousstone, and contains parts of everyone's dreams. Maginaryworld was almost plunged into darkness by Void when he shattered the Perfect Precioustone into pieces. As a result, Illumina was cast into an unknown world.
There are countless dream locations in Maginaryworld. Below are the main locations that the heroes Sonic, Tails, Knuckles and Amy go to:
- Temple of Light: The central location in Maginaryworld, and the place where the Precioustone is kept.
- Emerald Coast: This world is for those who enjoy peacefulness, it is the Dreamworld of Knuckles. It was nearly turned into an icy realm by Void, but was later restored thanks to Sonic and friends.
- Fire Bird: This world is for those who enjoy flying and freedom, it is the Dreamworld of Tails. Here, Sonic and friends must restore the Fire Phoenix, who was turned into air craft, to its former state.
- Nature Zone: This world is for those who enjoy being close to nature and its beauty, it is the Dreamworld of Amy. Here, Sonic and friends must gather the Precioustones to prevent the forest from becoming a desolate wasteland that was caused by Void.
- Riot Train: This world is for those who enjoy the thrill and excitement of adventures, it is the Dreamworld of Sonic.
