Designed to bend the will of the malevolent beings known as demons to one’s own, Demonology offers great power for those who are willing to take the risks involved and manage to survive them. Though, on the surface, demonology appears to work similary to the many other “pact-oriented” disciplines it is significantly more dangerous, and the costs involved are much greater. When a demonologist summons a demon, he must first bind it to himself through a contract. Generally speaking, and in broad terms, these contracts offer the demon residence within the body of the demonologist, typically inhabiting some corner of the heart or soul, in exchange for its allegiance and obedience to the demonologist for a specified amount of time – often the lifespan of the Wyser. Thereby, at anytime thereafter, the demonologist may surrender the control of his body to the demon, allowing it to possess him and make use of its powers on the mortal plane.
Most demons, however, are not content with merely a place to stay, especially one that is under the command of another entity. That is why there are often additional clauses that detail services to be rendered by the demonologist to the demon. The clauses are many and varied, but some common ones are payment of the demonologist’s soul to the demon upon the demonologist’s death, specified – or conditional – times when the demon is allowed free reign of the demonologist’s body on the mortal plane so that it might see to its own goals, or even that the demonologist become a servant or vassal of the demon. The last of these is typically for a set amount of time – usually equal to the length of time that the demon served the demonologist – though forever/eternity is common amongst the more powerful demons whose powers are saught.
Again, while similar to – say – an elementalist forming a pact with an elemental, there is rarely adverse consequences should the negotiations break down. In the case of the demonologist, there is always the danger of working with a being of pure evil who pursues his own agenda with the intentions of gaining more power through the demonologist. The most common fears that plague a demonologist is that a demon may simply decide to kill him, that he may lose control of his body to a possessing demon, or worst, that the demonologist may lose sight of a small, and subtle clause within the contract that instead reverses the typical relationship – making the demonologist work for the demon – without the demonologist gaining anything in return.
