In this world, the Middle Ages were not dark, but bloody. In this world, people froze in horror every time when the sky was darkened by the wings of the fallen. In this world, science returned freedom to humanity, and the Second Empire, the empire of people, stretched from ocean to ocean. Combat steamers ply the waters of the seas, armored trains wait on sidings, and army airships soar in the skies, but still the balance hangs literally by a thread. The era of steam is leaving, the era of all-good electricity is just beginning to take off, so even the smallest amount can plunge the world into the abyss of chaos.
