A group of refugees, originally thrown away by their own government. Nobody wants to have as a neighbour highly toxic, slimy creature that floods the entire area due to mating rituals. The feeble supply provided with the refuge ship proved useless in water environment and was quickly abandoned or simplified. That plummeted Batracyis to the very basics of survival again, akin to barbarism, with all the vestiges of knowledge and hi-tech treated as magic. Generations grew on the Nibiru, never knowing Earth or any other life, but also never caring about that. Communities turned into tribes and those eventually formed a confederation. Being able to leave water with relative ease, but always staying dependent on it, Batracyis try to take the best of both worlds.
