This worldbuilding idea just popped into my head a few days ago. Feel free to share this idea to make other new settings.
Reply below with a statement that describes a new setting. It cannot undue or contradict any of the previous statements submitted by others. The setting will be entirely described in 100 statements about it.
I posted that on: MeWe, and in 3 Facebook tabletop groups. Surprisingly the only one that got to 100 was on MeWe.
If I can get on my laptop soon (and have some time off work) I'll post up some of the results in another blogpost and video on YouTube maybe).
