News of a grand circus touring all of Equestria reaches the ear of everypony, bringing with it fun and excitement wherever it goes. When Applebloom gets a letter from her cousin Babs describing how amazing the circus was during its stop in Manehatten, the CMC are more eager than ever for it to reach Ponyville.

Owned by the grand ringmaster, Duo-tono. And performed by various creatures of Equestria, ranging from acrobatic minotaurs and gryphon clowns to juggling ponies and manticore-taming dimond-dogs. This tent-filled wonder has something for everypony to enjoy!

However, when one of the members of the circus goes missing, a dark and terrible secret is unleashed. One that only the circus, through orders of the crown, could keep at bay in order to keep Equestria safe.

Can the CMC help stop this growing disaster before it's too late? or will Equestria fall to the powers of darkness?

Declaimer: The title of the story pays homage to "Cirque du Soleil" for its fantastic performers and breathtaking shows. The proper French title is "Cirque de la Lune" meaning "Circus of the Moon", but instead ends with "Luna" on purpose for story telling reasons.
