Sometime in the 1920s, during her initial research into occult abuse, Dion Fortune:
...became aware of the existence of an inner-plane and an outer organization of initiates which was called the Occult Police.
Most of its operations were on the inner-planes, with adepti whose job it was to try to seek out occult abuse and spiritual wickedness and then to put an end to it wherever possible.
Certain occults groups in the physical world had their own inner section to work with the Occult Police and these were called Hunting Lodges. They were the physical plane terminals for the inner-plane Occult Police organization.
Another inner-plane group to help to control abuse was called The Watchers. They seemed to act as part of the Occult Police and their specific role seemed to be to seek out occult abuse, misuse of powers of the mind, and general misconduct in the field.
The Watchers would then hand over the information either to the Occult Police or to suitable individuals on the physical plane who would then take the necessary action to put the matter right...
The Watchers and the Occult police did not die with Dion Fortune, in fact they are still [1998] very much in evidence...
Dion Fortune was instructed in the procedure she should use should she ever need to get in touch with the Occult Police to report abuse or ask for protection...
While using the resources of this inner organization, Dion Fortune was able to obtain a great deal of information about occult malpractice, as the Occult Police headquarters seemed to be the clearinghouse for all messages.
Her connection with the Occult Police continued throughout her lifetime.
