The region where every story is a classroom. Under the University of Chicago — in the lab where the first controlled chain reaction was lit — the Santos Alliance trains 847 students in 23 languages on a live reactor. A teenager accidentally makes a sandwich sentient. The trains run on time and teach coding on the way. Chicago doesn't just build machines; it builds the people who build them.
Still rolling in on the rails — Rebecca “Rocket” O'Malley's flying-car safety board (looping in with the Vegas dust front) and Kai Nakamura's Asian-carp kitchens are written and on their way in. New rooms slot in as cards; the front door never has to change.
