A Loup-garou is the closest to the monsters of legend. These werewolves have been intentionally cursed by someone, usually a very powerful sorcerer, demon lord, saint, or one of the Faerie Queens to be possessed by a wolflike demonic entity at every full moon. They become near-mindless killing machines with supernatural speed, strength and ferocity. They recover from injury almost instantly, are immune to poisons as well as any kind of sorcery that attacks the mind. They can only be killed by a weapon made from silver which has been inherited—not just purchased. The curse of the loup-garou can be hereditary if the one who placed the curse specified it as such. Usually the person afflicted with the curse is aware of their condition and will have enough sense to isolate or shield themselves from society to prevent the horrible damage they would inflict on the rest of the people with the next full moon. As such, Loup-garou attacks on the populace are thankfully rare. The only one featured in the series to date is Harley MacFinn whose family curse originated from St. Patrick himself.
