Cursed Metal

Demons from century to century rush into the souls of people from the gray abyss, in which nothing has ever happened and nothing will ever happen... Exorcists and executors save souls of people possessed with prayers and fire and drive the unclean back into the emptiness that created them... and so it had to be until the end of his days.
But a man appeared who could command demons as if by his own vassals. And a new heresy spread like a plague through the cities. And they rose obsessed with the apostate monarch. And , and there was a big war in the air. A war in which the poison and daggers will mean no less than the army and the walls. War of all against all.
What, you ask, does Sebastian Mart have to do with this?
It was not worth him to take out the expulsion of demons, that's all.
