Copernicus - Data Panel

AIAI power: Hanse Angelnet — built around ship AI core with Conver upgrades, but largely self ascended

AI's ethos: Independent Opportunism
SystemCommon Names: Copernicus System, Danzig System

Symbol: Wooden Sailing Ship

Affiliation: Ties to Terran Federation, Sophic League — Solar Dominion presence since Version War limited to Riga

Colonized: 809 autonomous probe Philip K. Dick (nano autofac which contacted and joined Metasoft in 4790

Colonized: 1421 Hanse (launched 1001, Baltic League Habitat, Central Asteroid Belt, Sol System
Psyche Art and CultureMetapsychology: Opportunistic and resilient

Metaethics: Apart from the cosmopolitan Hanse polity, the Sophic League tree is a centre for Virtual Incarnation and Habilitation. Exvirch neogens usually migrate to live in the O'Niell habitats around Bergen 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, Solarism, Market Abundance Theory
Hamburg - Universalism, Humanism
Riga - Solarism
Mazda - Zoroastrianism, Buddhism;
Bergen - Buddhism, Soul Copyism, Platonic Materialism

Culture and Art: 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 are welcome to compete in the Danzig Hyperolympics, where any bio and/or hylo augmentation is both permitted and recommended.

The opportunistic and resilient NeoHanseatic League attempted to recreate the ancient Baltic Trading empire, but was nearly bankrupt after they terraformed Danzig by bringing cometary water to the dry world, and using nontoxic hypergreenhouse gases brought the temperature up to thaw the permafrost crust.

In 2058 the Conver Ambi arrived and set up an embassy/colony on the highlands of Danzig, advanced pohumans trading with and assisting the impoverished Hanse colonists, and leasing a large continent (Wendlant)for their cybercities.

In the breakup of the Conver Ambi the Solar Dominion took over, with the now hi-tech 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 relativistic attacks on Xi Bootis A (Shamash) from 4490 during the Version War. The Vec outpost was destroyed in 4608 by the Dominion Stormfleet.

The Solar Dominion terraformed Riga in 5500, and withdrew from the troublesome and independent Danzig, which soon formed trade agreements with the Sophic league and the Terran Federation.
