Quote from EsotericRule:
If I named them, they would not then be relatively unknown, now would they?
With a little work on the inet you can come up with reams of names of those who 'work' for it and have little time for glitz.
With a little more work you can find those who are born to it and shun the limelight for historic and current reasons. A search of 'black nobility' and 'ground rent' is a good start. The frontmen of 'Rome'...never lacked for funds.
You've got me curious: why do you search after such specifics?
