About the book: 2007 / What should a poor monk do when his beloved is accused of witchcraft and is about to be burned? Of course, call on the demon to help! Albeit not the most formidable one. But what should a demon who has descended to Earth to take a little rest do when some weirdo calls on him? We have to go to help! Well, then don’t leave them alone with the formidable medieval world, full of dangers! When you are invisible to people and even slightly able to fly, this is very helpful in the fight against the Holy Inquisition and bandits, and also greatly helps to bring some sense to inadequate rulers.
