Franz and Adam are monks from medieval Germany.
Adam is an extremely strict devout extremist, unshakable in his faith. Franz is a spoiled and cheeky son of a merchant, sent to the church by him, from where he was transferred to the temple (for the forgiveness of numerous sins :)
Faith invented, avoiding misunderstandings (in development).
Franz has a feature that even he does not know about or does not know, but he realizes. He is partly a demon. :D
