Altered Timeline (Mobius: 25 Years Later)
When Shadow took over due to timeline alterations by Sonic, the world capital of Mobius was moved to the city of Portal. There, King Shadow and Queen Sally ruled from Castle Mobius, at least until Knuckles and Lara-Su's coup d'etat in 3262 (25 years after 3237). 
Five years later...
After Shadow's defeat, Sonic was coronated as the new king of Mobius, with the capital still in Portal. Five years later, Manik and Sonia Acorn reappeared in the series, living with King Sonic and Queen Sally in Castle Acorn. Sonic and Sally were taking a night off to relax due to a celebration the following day. 
In the future, Angel Island is highly modernized and its largest city, Portal, can be described as a metropolis, with a large population and a monorail system.
