The remaining embers flare up again, and the beacon of humanity shines once more. The story will go on... (The setting has five eras: Era One: Before the Age of Navigation. Era Two: The Dark Age of Navigation. Era Three: The Age of Navigation, or the Golden Age of Navigation. Era Four: The Age of Turmoil. Era Five: The Age of the United Nations and Empires.) (P.S.
