Welcome to Speculative civilizations wiki, a site that deals with the idea of the scenarios of civilizations built by sentient and/or sapient beings. These sentient beings don't always have to be very likely to happen, but that said scenarios must have a rather realistic evolutionary and/or revolutionary history. A realistic culture also should be set in place for these beings with taboos, holidays, etc. A history of interaction of multiple civilizations in a given scenario is also accepted, as is seen in the "To Kuiper" scenario.
