The first Banks Orbital ever built can still be seen in the Gordelpus System
Central MPA system, colonized by the Kathelian Confederacy in the 2700's. Location of the first Banks Orbital, completed in 4226 A.T..
It became a center of wormhole construction, magmatter manufacture, and experiments in applied gravitronics under the Kathelian engineer-gods. When they suddenly vanished in 6304 (likely transcending) the system was cast into disarray and economic chaos. The new STC-aligned Erniac government came into conflict with pro-Negentropic and pro-Keterist influences, weakening the political market and allowing the Sonato system to buy the polityship in 6433.
Erniac, Erniac Government - Text by Anders Sandberg MPA political movement in the 6000's, seeking closer alliance with the STC and transformation of the materialist aesthetics into a colonisation aesthetic.
Kathelian Confederacy - Text by Anders Sandberg MPA polity, founded in 2378 by a group of wormhole engineering AIs. To some extent the Confederacy was an AI House, owning a sizable wormhole manufacture infrastructure, controlling several systems and having many allied biont clades. Their ethos was strongly aligned with the concept of the engineer-god, expressing its divinity through design and creation. It persisted largely unchanged until 6304, when large parts of the ruling AIs vanished into apparent transcendence; this both weakened and centralized the Confederacy, making it consolidate into a mere four-system polity. Politically the Confederacy remains very much MPA mainstream, with some Meketuur influences.
