2343 Before the Destruction of the Enterprise-C at Narenda III Space, the Final Frontier. With these words, one of the great TV shows of the modern era was launched. This show was Star Trek, which forms the base history of Star Trek: Yesterday's Voyages. We are set in what has been dubbed one of 'The Lost Eras', between the Khitomer Accords and thelaunch of the USS Enterprise-D. To be more precise, we're set in 2343, a full twenty years before the launch of that great ship. The Dominion is unheard of, the Borg are but a rumour, and a great age of adventure is taking place. The three powers we focus on are the United Federation of Planets, the Romulan Star Empire, and the Klingon Empire. On the fringes of known space are a variety of powers, both major (such as the Cardassian Union, discovered by the Federation eight years ago), and minor. ^[1]
