Mobius (referred to more recently as simply Sonic's World, also known as Mobius Prime due to its place in the multiverse of Zones) is the homeworld of the Mobians, Overlanders and humans in the Prime Zone. It was discovered that Mobius is actually a future version of Earth (in an alternate dimension). According to this universe's timeline, Earth's year would be approximately 14,016 CE, with Mobius' calendar year at mid-late 3237. It is still unknown exactly what was the starting point for their calendar, but its was likely calculated using what the Echidna Tomes call the Days of Fury. Mobius has endured many conflicts, including the Great War, the first and second Robotnik Wars, and a failed attack by the Xorda. Much of it remains under the control of the Eggman Empire, though some sections of it remain free from its tyranny.
