Doctor Eggman discovers an ancient
relic called the Reverie, an object with dream-controlling powers that allows the pure of heart to bring their dreams into reality. Eggman, wanting to use this power for his own gain, steals the Reverie and kidnaps Cream the Rabbit and her Chao pet Cheese to use as a filter to access the relic's power. Eggman activates the Reverie upon which its guardian seals Eggman inside his own dreams before he can do any harm to reality. Sonic, Tails, Knuckles, Amy Rose and Rouge arrive at the scene to try and rescue Cream and Cheese, to which the guardian also sends everyone to sleep and as a result enter Eggman's dreams. Upon awakening in the dream world, known as Reverie Haven, Sonic meets the Guardian of the Reverie and Dreamweaver, Ariem. Ariem asks Sonic to collect Dream Orbs for her so that she can restore Sonic's friends and reclaim Reverie Haven from the dreamscapes Eggman has constructed. After traveling through Scrambled Shores, Dream Factory, and Nightmare Maze, a monster known as the Guardian Hunter ambushes Ariem in an attempt to capture her for Eggman. It is promptly defeated by either Knuckles or Rouge, but Ariem is severely wounded by the encounter. The heroes then pass through Ego City, a dystopian imperial capital intended to be brought into the real world, before reaching the Dream Core at the center of the Reverie. The wounded Ariem, unable to directly reach the Dream Core to banish Eggman, transforms into a small orb which the heroes intend to carry. Guarding the Dream Core is Nightmare Eggman, a twisted version of the doctor with reality-warping abilities. Tails flies up to the Core to receive Ariem, while the others race through the void, passing Ariem to each other in a
relay race in order to reach Tails at the top of the Core's tower. After reaching the top of the spire, Nightmare Eggman raises the tower higher and attempts to crush all 6 heroes simultaneously, but Tails launches Sonic onto a nearby platform, who races up the side of the tower and tosses Ariem into the Core. She is immediately restored to full health, banishes Eggman, and activates the Dormancy Protocol, which will shut the Reverie's dream-manipulation down for a millennium. When the heroes awaken and reunite, they begin to make plans for a victory dinner. Eggman awakens as well, but Cream sends Cheese to press a button on his machine's console, sending him back to sleep. Tails then reveals to a saddened Cream that he programmed a back-end into the Dream Core that will allow her to visit Ariem at any time, as well as allowing for the others to explore the remaining dreamscapes. ==Development==
