Have you ever had a moment of inspiration that came out of nowhere, yet helped to enrich the world you are building so much that it became extremely significant? I know I had. One of my best ideas for world-building came to me while I was studying something that probably had to do with math. One moment, I was doing some exercise or memorising, then BAM, comes a very simple symbol that essentially defined an entire people by dividing it into four separate cultures that used to live together. This separation then became one of the cornerstones of the universe I am still building now and was the foundation stone for the "Four Philosophies." What about you? Have you ever had such an unexpected idea that helped to define a whole world? Or maybe a small one that ended up working out really well? I want to know about it all!
