The Source is a mysterious character / entity with insider information and great power. Originally the founder of ImAbyss operation, the source once offered protection to investigators before later abandoning them. The main condition the Source outlined being that investigators disseminate a strict set of rules, one of which being that all information and materials be handed over for “cleansing”.
It’s unknown now if the Source has malicious intent since many objects once in its possession have demonstrated unexplainable properties or paranormal activity. This is perhaps related to suspected ritual ceremonies performed by the Source. Very little else is known about this entity and its demand that no one digs deeper.
