And we thought demons were supposed to be tough. This creature, after being disarmed, could only struggle pointlessly - a strong Brainer gal was enough to restrain it. When we showed him some cheap VooDoo fetishes to maybe avert the possession, it sent him crawling up the walls, babbling incoherently, then when we applied some more, he dropped to the floor, foaming from his mouth and convulsing. Curious. Well, the possession wasn't gone but at least he finally kind of calmed down. So, we proceeded to interrogate, but to no avail. After some milling about, someone had the idea that we need to turn to professional works in that field - and we happen to have an old tome called 'Malleus Malleficarum', which proclaims itself as the leading source on that topic. Sadly, when we put the demon interrogation practices found there to work, the patient died even quicker than a pureblood probably would, if one would be so ignorant as to use such techniques on a non-possessed person.
