When I was younger, I read a book that absolutely fascinated me. I checked it out from the library again and again. It was all about creating imaginary kingdoms and building them in miniature form with old cans, oatmeal containers, cardboard boxes, and such. I loved that book. I remember turning a big table into my “kingdom,” and all the people who lived there worshiped the Great God Tagamet. They were somewhat inspired by ancient Egypt, as I recall.
I still enjoy creating worlds, though usually I make maps of them or write stories, rather than creating miniatures. When I wrote my novel, “The Dice of Fate,” I had a lot of fun figuring out how things would be. What climate was I going to choose for the area my story was in? What type of plant life? What type of animals? As it happened, I chose a mountainous area with a wide valley and a river running through it. The trees were mostly deciduous, though there were some conifers too, and there were ancient ruins and a mysterious Road that had been there for ten thousand years or more.
Once you know what kind of place you are imagining, you can have lots of fun deciding about civilizations, trade routes, where resources are, how people get from place to place, what kind of agriculture they have, what kind of technology, and on and on. The possibilities are literally endless!
What to do with this information? Write a story, draw a picture, create a roleplaying scenario, make a miniature, or just dream. Imagination keeps the mind young.
