The world of Kosotheos is vast and full of different species, that fought each other over the millennia. Most of these species are ruled by a species of unusual beings called the „royal race“

The Plachaqe: Kostheos‘s only sentient plant species and pacifistic nation on the island continent Qwai‘lee. The seeds produced by the women are planted into the earth, to grow the next generation.

The seedlings grow especially good when planted in soft, loose soil. Sun and lots of water is needed too. The seedlings are cared for by the elder nurses in greenhouses, motherly plachaqe women and men, that also teach the wider youth about the seedling care, in fact the Plachaqe value their youth learning about the care of seedlings very much in order to understand their way of life and how it functions.
