The backstory for my next project, 'Set In Stone' has been written. 9360 words at this time, but that will almost certainly change a bit as the backstory is massaged.
'Set In Stone' is original fiction, and will be multipart. It will also be rational fiction in a stonepunk theme. Humanity on the colony Nirvana had advanced technologies taken away, but not all of its knowledge. As the simplest possible way to describe it, imagine the Flintstones, but with everything making sense.
The backstory describes how the people of Nirvana got to be where they are. The in-universe writing will rarely reference elements of the backstory.
