“ My name is Ferrum. I was the first, born of the forges, when mankind first began to experiment with iron. I rose from their imagination, from their ambition to conquer the world with a metal that could slice through bronze like paper. I was there when the world started to shift, when humans took their first steps out of the Dark Ages into civilization. For many years, I thought I was alone. But mankind is never satisfied. Others came, risen from these dreams of a new world... Then, with the invention of computers, the gremlins came, and the bugs. Given life by the fear of monsters lurking in machines, these were more chaotic than the other fey, violent and destructive. They spread to every part of the world. As technology became a driving force in every country, powerful new fey rose into existence. Virus. Glitch. And Machina, the most powerful of all. ”
