Also known as the Galactic Atlantis, this temperate temperate terra was a mythical lost human colony that was rediscovered in 9991. It orbits the star of a quadruple star system (RS 8409-3163-7-1490559-680 in 9.7.3.).
Before its rediscovery, Sanctuary was a great mystery. Many theorized about its location, as well as its supposed advanced tech. There were many science fiction stories and shows made depicting the supposed culture of the settlers of Sanctuary.
The sci-fi holonovel When Worlds Collide is the most famous fictional work set on Sanctuary, depicting a hyper advanced civilization on the edge of the Milky Way who have made contact with a number of other civilizations including the First Civilization. It spawned a number of sequels along with a holoseries based off of the book.
According to the logs of the ancient colony ships located on one of the moons of Sanctuary, the original colonists left at the height of the Eastern Galactic Rebellions. They were a group of extremely intelligent scientists and pioneers who were tired of war and their ideas used for destruction.
Fearing that the UFSS was doomed to be destroyed and that a new Dark Age was coming, they built massive ships in secret and installed prototype Warp Drives that could travel faster than those of the time. They had discovered a planet perfect for human life a very long distance away from Earth and the core worlds. With their new drives it would take the colonists fifty years to get there. The technological equivalent of their Warp Drive wouldn’t be invented for another thousand years.
When they reached the planet five decades later, they found that life already existed on the planet, but only in the form of small plankton-like life in the seas and a green mosslike substance on the land. The colonists first had to introduced terrestrial life to the planet and after another twenty five years the planet was transformed into a paradise where humans could live. The colonists dismantled all but one of their ships and left it on the closer of the two Selena-Class moons to keep a watchful eye on their history and on the skies in case future humans found them.
The current population as of a 9995 census is 1.2 billion.
When the first colonists first settled the planet they built metallic but primitive structures. They had a philosophy of simplicity and not relying too much on technology.
After living like this for thousands of years, a rift began forming between a group that wanted to build a more advanced society and a group wishing to keep themselves more simplistic. Not able to find common ground the groups split. The former group headed north across the mountains and ice near the equator and to the fertile grounds of the north. They built a vast technological civilization across the north.
In the south things remained the same. Occasionally people who were dissatisfied by either side would travel to the other human civilizations where they would give the alternate lifestyle a go.
Located 44392 light years from Earth, this world has a diameter of 12687.1 km with a gravitational pull of 1.1 G. It’s mass and ESI are very close to Earth norms.It has a semimajor axis of 0.89 AU giving it a year length of 327.2 days. Its day length is currently 14 hours and 52 minutes. It has eleven moons, two of which are Selena-Class and the other nine being captured asteroids. The planet along with the system is 4.9 billion years old.
With a steep axial tilt of 117°, the planet has incredibly wild seasons that the original teraraformers took into account when bioengineering the plants and animals. Because of this, the equatorial regions are mostly ice and snow while the poles remain snow free. The planet has a current mean temperature of 4.8 °C. It has a nitrogen oxygen atmosphere with a pressure of 0.8 ATM at sea level.
Most animals are very migratory, migrating during the seasons to find a place where there is a night and day cycle.
Currently, however, a terraforming company is working on the planet to alter its tilt so that the planet can warm up and become more Earthlike after getting permission from the humans of Sanctuary.
