At the brim of all understanding lies the barrier of this world. Only the greatest sailors have seen it. No one has been past it until now. What lies beyond? What has escaped from it? What was never trapped inside?
In the tide of steam and machinery, who can touch the extraordinary? In the fog of history and darkness, who is whispering? I woke up from the mystery and opened my eyes to see this world: Firearms, cannons, giant ships, airships, differential machines; magic potions, divination, curses, hanged men, sealed objects... The light still shines, and the mystery has never gone away. This is a legend of a "fool".
