Interlude:

All mainstream Sonic games released after Sonic Generations assume that Sonic triumphed over the Time Eater and saved the space-time continuum. However, (in a plot-twist similar to that of The Legend of Zelda: Ocarina of Time), the following timeline assumes that he ultimately failed to defeat it, letting it continue its rampage. During said rampage, the Time Eater also broke free from Dr. Eggman's control, forcing him to team up with Sonic once more. While the two managed to finally defeat the monstrosity, it managed to pull one final stunt in its dying breath: it formed a two-way split in the timeline. One path would see Sonic continuing his adventures as before, with no alterations whatsoever, while the other path (containing separate incarnations of all the characters with intact memories of Generations and back) is as follows: After being forced to relive his entire past a second time, Sonic became exhausted from 20 years of crime-fighting and decided to take a break from his adventures. He moved back to Station Square and bought an apartment where he would live for a long while if not forever, promising that he would still be there to protect the world from evil, and go on some adventures from time to time, provided that he could relax and devote time to other things too. As mentioned above, the following story takes place in the latter timeline, and begins after this interlude...

Chapter 1: A New Home:

Somewhere in Mobius, was a large neighborhood, consisting of a middle-class area full of normal houses, and a rich area full of mansions. In the rich area, was a pale gray mansion, which had ivy growing up its side, and a swimming pool and a chao garden in the backyard. This home was on sale for a price of 1,000,000 gold rings. Nobody had bought it yet, and it didn't look like anyone would. But one day, someone did.

Sonic the Hedgehog was the well-known hero of Mobius, constantly protecting it from the forces of evil, particularly Dr. Eggman. For this reason, he was very wealthy. Despite his riches though, Sonic did not have a real home. All he had was a small apartment in a building called "Casino Night Zone". Since it was above the casino, it always smelled of things like tobacco, alcohol, and (ocassionally) drugs. Also, the ringing and beeping of slot-machines, the folding and flipping of cards, and the screaming, laughing and talking from everyone who came to the casino made it incredibly noisy at night, making it next to impossible to get even the slightest amount of sleep.

Relieved to finally get a good opportunity to move out of there, Sonic non-hesitantly purchased the mansion, and since it was too big for only himself, he let his friends live there too as his housemates. A few days after spending the 1,000,000 rings, Sonic, and his friends Tails, Knuckles, Silver, Blaze, Shadow, Rouge and Amy all began moving their things into the mansion.
