Multispecies utopian civilisation that developed in the Black Acropolis dyson swarm; consisted of human baselines, tweaks, aioids, Enhanced Dolphin provolves from Hwii, and various clades of the xenosophonts known as Ultimates
Timeline
4001 - A clade of heterodox dolphin colonists from Hwii arrive at the Black Acropolis habitats, fleeing the rigidity and conservatism of Okeanism.
4023 They are joined by an expedition of Space Adapted Humans. The Dolphins and SAH contact the Ultimates and start to create a synthetic culture
4220 - Elements of The SynBios - a synclade of human, dolphin, and neo-reformist Ultimate that developed in the early decades of the Glorious Communion in the Black Acropolis habitats, sets forth to colonise further star systems.
4237 - Signing of the Gerkletoss Accord
4590 - the wormhole to the Black Acropolis is closed due to the Version War.
5768 - The Gerkletoss system is re-connected to the Wormhole Nexus
6420 - The AI part of the Gerkletoss civilisation rebels against the constraints on their development, beginning fast autoevolution. Massive use of exotic matter and spacetime engineering leaves the region extremely dangerous. A number of refugees flee to nearby star-systems in Ultimate-designed generation ships
8693 - Human and dolphin refugees from the Gerkletoss rebellion/transcendence arrive at Skiiws'nnii and begin the terraformation of that world.
Hwiisi - Text by Anders Sandberg Neodolphin language spoken on Hwii and many other mainstream augmented dolphin worlds. Derived from the dolphin language spoken on Okeanos (also known as SeaSpeak).
