Systems are anchored by a central, high-mass celestial object, typically a Star, around which Planet, Celestial Objects, and other cosmic phenomena orbit. Systems are surveyed by Science Ships, and are controlled by Outposts.

Some systems contain habitable worlds suitable for Colonies, while others may hold strategic chokepoints, valuable deposits, or hidden dangers. Establishing control over key systems is essential for territorial expansion, defense, and economic growth.
