Species: Obsession
Family: Demon
Risk level: Medium
Weaknesses: Killing members of its cult
Description: A particulary nasty subspecies of demon, with ability to corrode minds of people that know its true name. It specifically cultivates a group of people to create as big of a cult as possible. Anyone that knows its name becomes obsessed with it, slowly destroying everything that made them 'them' and transforming into the vessel of pure fixation.
But of course someone has to first learn about it, to be able to let it influence them. If that particular demon doesn't have group of cultists it invades the minds of highly susceptible people, like artists, and one step at the time nudges their train of thoughts towards learning of it. It doesn't have any kind of form, existing purely as condensed thoughs and essence, not being able to personaly come to this realm.

Their cultists can be very dangerous, due to their possibility to quickly expand their group, by forcing others to know the name of their false god. If you learn of any activity involving those kinds of cultists, it is required to inform nearest monster hunting factions, to let them contain their activity.
Personal notes: "It is extremely hard to deal with them on your own. They only way to limit them is to exterminate every single member of their group except a single one. From what we currently it isn't possible to heal them of the mind corrosion, due to the fact that there is no mind left to heal. It doesn't help that if even one extra person survives and escapes during the wipe out, they can quickly rebuilt their entire cult from ground. I prefer killing regular beasts that dealing with mind benders." German Silver, member of Blood Hunt
