TransapientCopernicus system: The first transapient in this system ascended from the colony ship's core AI

AI's ethos: Independent Opportunism
SystemAffiliation: Danzig has ties to the Terran Federation, Mazda is affiliated to the Sophic League and Riga is a member of the Solar Dominion.

Colonized: The autonomous probe Philip K. Dick arrived in 809 AT and eventually joined Metasoft in 4790. The Kontore League colony ship Hanse arrived in 1421
Psyche Art and CultureMetapsychology: Opportunistic and resilient

Metaethics: Danzig is an independent Inner Sphere polity, with close ties to the Terran Federation.
Mazda is a Sophic League Dyson tree and is a centre for Virtual Incarnation and Habilitation. Exvirch neogens usually migrate to live in the O'Neill habitats to adjust to real life; many virch characters are programmed with artificial personas for roleplaying which must be shaken off to live successfully in the real world.

Religions and Ideology:
Danzig - Universalism, Cosmism
Hamburg - Universalism, Humanism
Riga - Solarism
Mazda - Zoroastrianism, Buddhism;
Bergen - Buddhism, Soul Copyism, Platonic Materialism

Culture and Art: The culture on Danzig is hi-tech and closely integrated with the biosphere of the world they have paraterraformed. The seas and forests of Danzig are home to many augmented humans, often engaging in sport and other recreational activities while cyber-multitasking. All worlds in the Copernicus system are welcome to compete in the Danzig Hyperolympics, where any bio and/or hylo augmentation is both permitted and recommended.

History

The autonomous probe Philip K Dick arrived in 809 AT, and surveyed the system. This aioid entity remained in the system and eventually joined Metasoft, establishing a base on Rhine, a moon of Lipperhey.

The Hanse arrived in 1421 AT from Solsys, and established habitats on the moons of Harriot and Lipperhey. Lipperhey became the most important planet in the early system, where two powerful (and rivaling) polities became established: the Federal States (capital: Bergen, a moon of Lipperhey) and the Amity, on Mazda. The Federal States were a loose coalition of different groups of colonists, while the Amity were inspired by an ideology that valued effective altruism, goodwill and social capital above all other forms of wealth.

In 1466 the Hanse core AI ascended to S:1, and began to construct a worldhouse roof over the moon of Harriot known as Danzig.

In 2358 the Conver Ambi established an embassy on Danzig, and became increasingly important over the next millennium or so. The Federal States opposed Conver dominance in this system but were eventually sidelined and dissolved in 2800. Amity on the other hand continued to exist in various forms until the Second Federation, and was revived in a modified form several millennia later.

After the breakup of the Conver Ambi the Solar Dominion took over, while Danzig remained independent. A new culture known as the Rezarki emerged on this world, and remained important until the 7000s.


The Metasoft outpost on Rhine retreated to Rheticus, the companion star - a red dwarf at 1200 AU. This was the base for relativistic attacks on Xi Bootis A (Shamash) from 4490 during the Version War. The Vec stronghold in the Rheticus system was destroyed in 4608 by the Dominion Stormfleet.

Riga joined the Solar Dominion in 5500, and Danzig formed close ties with the Terran Federation. Meanwhile, the Reformed Amity culture on Mazda grew closer to the Sophic League, and this moon was eventually converted into a large Dyson Tree habitat.
