The gas giant Harriot as seen from its terraformed moon, Danzig
In 497 AT (2466 c.e.) the autonomous probe Philip K. Dick was sent to Copernicus, a G8 class star 41 ly from Earth, and established a magnetic energy collector/autofactory on Rhine, a moon of the jovian world Lippershey. A Baltic League colony ship, the Hanse,was launched towards this star by the First Federation in 1001 AT. The Hanse arrived in 1421 AT.
The first planet from the star, Janssen, is a hot neptunian world; it currently has a ring of photovoltaic power stations in polar orbit; otherwise it is untouched. The second planet from the star, Galileo, at 0.11 AU was slightly smaller than Jupiter. A second epistellar subjovian Brahe orbited at 0.24 AU. None of these planets have moons because of the small size of their Hill sphere region.
Harriot, the fourth planet, was a watery gas giant world at 0.71 AU, with a single large moon (Danzig) which became the NeoHanseatic colony. The NeoHanseatic colonists brought cometary water to this dry world, and the moon was terraformed despite its long day (nearly sixteen times as long as Earth's).
A 200,000 km jovian, Lippershey orbits at 5.5 AU, providing protection from cometary impact,.with three moons Mazda, Elbe and Rhine. When the colonists arrived, the autofac built by the Dick was still active on Rhine, and in 4790 it made contact with and joined Metasoft.
In 2058 the Conver Ambi arrived and set up an embassy/colony on the highlands of Danzig, advanced posthumans trading with the impoverished Hanse colonists, and leasing a large continent (Wendlant).
In the breakup of the Conver Ambi the Solar Dominion took over, with the now hylocyborg culture of the Hanseatic colony remaining independent. The Metasoft outpost on Galileo retreated to Copernicus B, a red dwarf at 1200 AU. This was the base for long distance relativistic attacks on Shamash from 4490 during the Version War. The vec outpost was destroyed in 4608.
Danzig is 6404 km in diameter, orbits Harriot at a distance of 979,850km and is tidally locked to its primary; this means the day-length on this world is 15.9 standard days long. The world was terraformed primarily using an early form of Weather Machine technology.
Danzig is now an independent Inner Sphere world, affiliated to the Terran Federation and Sophic League, with the Solar Dominion presence limited to Riga. The Hanse cyborg culture is both hi-tech and bound to the nature of the world they have lovingly terraformed. The seas and forests of Danzig are full of augmented humans often engaging in sport and commerce simultaneously using cybermultitasking.
All worlds in the Copernicus system regularly compete in the Danzig Hyperolympics, where any bio and/or hylo augmentation is both permitted and recommended. This competition draws spectators from the entire system and further afield, especially since the competition was opened to competitors using Ultimate Muscles.
A Sophic League Worldtree is in place on a moon of Lippershey, while in a series of O'Neill habitats set up around the outer microjovian (Bergen) live a hybrid race of synthetic human characterbots ruled by the Doctors Evilbot and Doombot, who are dedicated to lives of peace and contemplation following their liberation from role-playing constraints.
