Administrators

Administrators are wealthy or affluent Adepts who pay other Adepts to investigate cases of the supernatural for them. By far the Order of Immortals deals in this sort of thing the most, hosting online websites that offer jobs for any Adept, be they Squad member or Freelancer, to look into.
Reporting back on the job and providing proof of results, with 'results' meaning evidence you found an agent of the Darkness and dispatched it, earns the Adept a reward. Professional Adepts, especially Freelancers, make much of their living off of this activity. 
The best Administrators do more than just hand out newspaper clippings with an address, they organize other Adepts around them who can mine data professionally (Heralds, Prodigy) to act as backup for Adepts who go in to investigate (they can do the research while the Adepts in the field do the legwork). Some Administrators even provide backup teams in the event that matters get out of hand.
