This is an unusual system consisting of 3 G class main sequence stars, one type K2 V star, and two red Class M main sequence dwarfs, and scattered amongst those stars are twelve Earthlike planets. Humanity has been colonizing the stars in the Galaxy for a long time now in slower than light starships. The origins of humankind have been lost to the distant recesses of human memory, the initial era of long duration interstellar has come and gone, and two thousand five hundred years ago, the emmissaries of mankind had found a most unusual star system, a star system with twelve terraformable worlds. The worlds were prompty terraformed by a group of beings called the overlords, the overlords were not human, its not entirely clear what they were, the leading theory is that either they were a group of aliens or perhaps some very advanced machines. The humans on the twelve worlds know very little as the records from that time are fragmentary, and many people were not literate in those days.
At one point after the initial colonization, legends say that the humans were cast out of paradise, most modern historians translate that to mean their devices stopped working for them and humans for the first time in many millenia had to rely on their own skills, and those skills were very meager in those days. Promptly space travel was lost and with that the worlds were isolated from each other for over one thousand years in a new dark age which only recently ended 500 years ago. The last 500 years was an age of discovery and adventure, the reestablishment of space travel, and the contacts renewed between the various branches of humanity on the various worlds of the system.
The system consists of 6 stars, 3 yellow G Vs, 2 red M Vs and 1 orange K2 V star.
Component A is a yellow G2 V class star, it consists of 5 planets and 1 moon, two of them are uninhabitable as they are too close to this star, the third planet is a gas giant with one large Earthlike moon, preceding that gas giant in the L4 trojan point is an Earthlike planet, and following that gas giant is another Earthlike planet with an airless rocky moon. Just beyond the gas giant is a red dwarf (class M5 V) with an Earthlike planet orbiting it at 0.01 astronomical units. Altogether the A component of the Twelve Worlds system has 4 habotable planets.
Component B is also a yellow G2 V class Star, it circles opposite Component A with a mean seperation of 30 astronomical units, which stays fairly constant throughout its entire mutual orbit, this star has seven planets, two of them are uninhabitable because they are too close to their star, one is uninhabitable because its a gas giant, this gas giant is about the size of Jupiter, has 5 airless bodies in orbit around it, and two Earthlike planets preceding it in its L4 trojan point, and two Earthlike planets following it in its L5 trojan point, the habitable planets in this section consist of two pairs of binary planets held apart and seperate in their respective trojan points on opposite sides of the gas giant
Component C is also a G2 V class star with 5 planets, to uninhabitable rocks too close to the star, a lone binary planet orbiting within the habitable zone, and a second red dwarf (class M5 V) with a single planet in close-in orbit further away. for a total of 3 habitable worlds.
Component D: The most remote world in this system is orbiting component D a type K2 V orange dwarf star, the orange dwarf boasts only two planets, one of which is habitable and an asteroid belt further out.
The inhabitants of this solar system are only slightly more technically advanced than we are, the space technology is more advanced as they travel about in their solar system, their electronics is comparable to our own, they have harnessed fusion as a source of energy, but only in huge magnetic confinement reactors. The space propulsion technologies employed are very familiar to us, except these are more developed, loops of superconducting cables are employed for magnetic sails, solar sails are also used with the multiple stars in this system as are fission reactors and ion drives, very large fusion reactors are used on huge ships. On planetside people still get around on ground based cars, and fly in airplanes, space travel is affordable for the wealthy, a typical ticket to travel interplanetary may cast anywhere from 10,000 to 100,000 credits, volume of traffic is low compared to air traffic on a single world., the population of the tweleve World system is something in the neighborhood of 12 to 15 billion people.
