Ramcat was a world within the Laputan Guardianship. It frequently served as a neutral port of entry for several interstellar entities, including the Compact and the Realm. At 12,000 kilometers in diameter, it was remarkably Earthlike, though Nolan Rosc speculated the Office of Colonial Development would have bypassed it for development. Most aliens came to Ramcat via Armaneya City, an orbital city that served as traffic control for the planet.
