[Way With Worlds appears at Seventh Sanctum at at MuseHack. It focuses on worldbuilding as a writer or setting designer and is included here to help our readers who craft fictional settings]
Thanks to heavy worldbuilding you’ve got your setting, and in that setting you’ve got intelligent life (probably). Now that you’ve got sentient species in your universe,it’s time to work on their Culture and probably Civilization. I’m capitalizing deliberately, by the way for when I’m getting abstract.
Culture and Civilization are something we talk for granted because we’re used to living in them all the time. But they’re also huge elements of world building because of what they are – and taking them seriously is important because they are massive definers of intelligent life.
