Since the dawn of time, the Corsican shepherds lead their herds in the mountains for the transhumance. On this occasion, fairies and will-o'-the-wisps come to their aid.
But this year, shortly before the start of the transhumance, two young creatures in search of adventure decide to steal the precious Color Crystal and their prank turns into a disaster.

Walk the paths, solve the puzzles and help our heroes return to their world while allowing transhumance to take place.
