Mentions of them are present in the earliest chronicles. Powerful entities hid in the shadows of humanity and influenced it. Small communities grew into huge cults, because of which the Inquisition burned entire cities. Demons, as a rule, pursue their own goals, but there are special rituals and spells that can force a demon to appear to the caster and carry out the order. Such binding spells bestowed great power, but communication with demons sooner or later destroyed any sorcerer who resorted to forbidden magic. There were legends about a great master who managed to learn the names and symbols of demons, which allowed him to use them without harm to himself. He wrote down the results of his research in a special book, which he called Ars Demonium Invocatum. Many hunters died trying to get the book, but its traces, like the traces of the sorcerer himself, were lost in history. You have luck, Ars Demonium Invocatum is in your hands. Now all that remains is to decipher the book and gain knowledge that grants unlimited power.
