Mittgarten
A highly Balkanized low-fantasy medieval world. A major war has recently ravaged the Northern Kingdoms and whispered rumors of witches and their dark sacraments seem poised to erupt into a holocaust of unparalleled proportions.
Campaign name: The Secret Letter
The high inquisitor wants the secret letter the duke (who is being tried for witchcraft) wrote to his daughter so that he can use it to implicate them both in the practice of witchcraft and thus take the duchy for himself, but is having trouble getting it with his inquisitors because it has been sent in secret.
Theme: triumph of the spirit (perseverance of good and righteousness, in the face of evil and nihilism. Retaining one's humanity in the face of tragedy and malevolence is the highest good/leads to redemption)
