Location from Iron Prince by Bryce O\
The star system where Galens Institute operates — one node in the Intersystem Collective's network of human civilization, where the war with the Archons is always present but often abstract.
The Astra System is where most of the series takes place — a relatively safe inner system far enough from the Archon front lines that the war feels like news rather than reality. Cadets train for a fight many of them may never see, which creates the strange tension of Galens: military academy as sports league, existential war as background noise. The Laurent family holds significant influence in the Astra System, making Aria's relationship with Rei not just a romance but a political statement. Power in the Collective flows through military rank, CAD User status, and family connections — and the Astra System's elite families sit at all three intersections.
A populated star system with multiple worlds — orbital stations, planetary settlements, and the infrastructure of an interstellar civilization. The Astra System is home to major military and educational institutions, including Galens Institute. Space travel between systems is routine but the sense of frontier danger increases closer to Archon-contested space.
