In this world, the Middle Ages were not dark—they were bloody. In this world, people every time froze with horror when the sky was covered by the wings of the fallen. In this world, science returned freedom to humanity, and from ocean to ocean stretched the Second Empire—the empire of people. War steamships cut through the seas, armored trains wait their turn on spare tracks, and army airships glide in the skies—but still, balance hangs literally by a thread. The steam age is fading, the era of all-good electricity is only just gaining momentum—so even the smallest thing can drag the world down into the abyss of chaos.
