So; you have created characters, you have a story, you have background, you have built a world and all of its rules, this is excellent. This is shiny and good, it has sparkle!
When one is thinking of making something beautiful out of whatever one discovers in the bottom drawer, one needs not only imagination and purpose, one normally needs some kind of glue or other to make all of the pieces come together and, as it were, unify.
Back in the days when Scratchy was still young, the tribes of Eire would, at times, need to communicate from afar and in secret. They would find highly reflective stones or would polish bits of metal and try to direct the light of the sun onto them. Using a code, they would flash a simple message to their compatriots. In later times, I heard about some war in distant Ippon over trade, the natives of an island under Navajo protection has been inconvenienced and the trade deal had become much less voluntary than they would have liked. In order to keep their movements and tactics over telelegon secret, they spoke to one another in the old language of their ancestors, a tongue even the most applied Ipponese intelligence officer could not know.
Eventually, like all codes will be, it was cracked but they found that the messages made no sense. Now, the Ipponese should have - with their own very lyrical and at times metaphorical language, have thought about this but they did not.
They lacked the context, in this case the cultural context that shaped the way Na-Dene is spoken and how it describes certain things, events, and even people; its slang and idioms. The Navajo has invented layered encryption and their innovation became the new standard across both the Empyraeum and beyond.
There is a valuable lesson in this.
How many hours, weeks, and days have you spent writing, rewriting, developing characters, creating art for them, perfecting, researching, rewriting again, refining....and so on until you knew the inside of each character's head and their 'life' perhaps better even than your own? Shiny indeed.
