An extremely large, populous coastal city, and the capital of the UF. Known for its hilly terrain, cable cars, and suspension bridges (the longest of which now connects to South Island). More like San Francentral City, right?

The capital of the Eggman Empire; a deadly and nonsensical city that more closely resembles a non-OSHA-compliant death-factory mixed with an amusement park, this neon-decorated sea of steel, concrete, chemicals, and smog consumes a good chunk of what used to be Central City.

A densely populated, highly urbanized city with a soaring skyline of towers. (Essentially an equivalent to New York City, just exaggerated, and with more high-flying skyways.)

Reduced to a radioactive wasteland of abandoned and largely destroyed military infrastructure after Eggman's bombing, there's little reason for anyone to visit Prison Island. Some robotic GUN defenses remain stationed on the island to deter scavengers.

Still partially flooded to this day, Station Square lies in total ruin. Blue Ridge is a community established on the northern edge of town, home to many refugees from the Perfect Chaos disaster. The northern parts of the region can get rather cold, and the mountains are snow-capped.
