The idea of an Elven Jester using song and tonal frequencies to control the sands of the planet, and the havoc it causes against the opposing human forces, is a really neat unconventional weapon. Unfortunately, the structure was very difficult to follow due to the lack of periods and grammatical issues. Based on the "copia" in your document title, I suspect English is not your first language. I applaud your efforts to not only write a story, but translate it for others to read in 48 hours. While it didn't work flawlessly in this case, I hope you give it another shot in the future or continue writing in Italian, as it would seem you have some great ideas to write about!
