Sonic, Sonia, and Manic, the royal triplets of Mobius, all have royal duties to do, and Sonic and Sonia got the most of it because Sonic is the soon-to-be king of Mobius since he is the oldest son, and Sonia's the soon-to-be queen of Mobius since she is the only daughter and second-oldest. Manic, the youngest of the three, wanted to play with them one day, but people kept asking Sonic and Sonia to help them with stuff, and so they couldn't. So Manic, Sonic, and Sonia decided to have some time to themselves
(Kind of based on the song, "Sister Time" in Elena of Avalor: Model Sister)
Sonic's dark past has come back to haunt him, but he has found Robotropolis again! But Eggman kidnaps Sonic's siblings, and every time Sonic rescues them, Eggman snatches them back up!
What is Eggman up to? What does it have to do with the "Flames of Disaster"? And why is he trying to expose Sonic's deepest secret?
Also, what's gotten into Shadow? Why is he being so nice to Sonic?
