I'd tell you I know where this story will take us, but that'd be a lie. The outcome will be just as much a mystery to me, as it will be for you. For each day of November, a different character will feature from across Star Trek. A different prompt for each. A different theme song. Together they will create a loosely connected, and very random, story.
