Sanctuary is a planet in Terran Federation space.
Starship Troopers novel[]
Sanctuary is a human-colonized planet. It's very similar to Earth in most ways, even has a parent star resembles the Sun and a natural satellite similar to the Moon. However, according to Rico, its biosphere is very lagged behind, almost like Earth in Carboniferous due to the stagnant evolution, as the result of lacking natural radiation to cause mutation in organisms. Human colonists have brought their own plants and materials to the planet which quickly overran the native wildlife. The local population largely supplies the Federation's military, based on the planet surface and in orbit.
The Federal Military uses Sanctuary as a major military base and a resort, also the backup HQ in case of Earth being taken by Arachnids. The location of this planet is the top secret in the Federation, all pilots and captains who know this critical piece of intelligence have undergone hypnosis to commit suicide once captured by enemies, in order to keep the secret from leaking.
Starship Troopers 3: Marauder[]
Sanctuary is hidden planet within the United Citizen Federation with at least one large ocean.
In orbit over Sanctuary are the Federal Fleet Headquarters which maintain the Fleet and consist of several orbital stations. Its location is top secret, as if the Bugs were to discover it, they would be able to destroy it and have free access deep into the Federation and Earth. Only a handful of Captains, including Lola Beck, know Sanctuary's coordinates.
During the Second Bug War, Dix Hauser takes Johnny Rico to Sanctuary's Fleet Headquarters, along with a surviving squad of his troopers from the Battle of Roku San. They were then transported to the Athena class starship Shiloh which carried seven Marauder Mech Suits. Rico and his troopers were then enlisted into the Marauder Project as the ship left the system.
