The Reeves (Greyfaces)

Somebody's got to do the paperwork, and this job is left to the
Reeves. They do it quite well. So well that they are the
de-facto bankers of the Known Worlds and probably one of the
richest factions in the universe - although few realize just
how rich they've become through their loans to noble houses.
Just about everybody owes the Reeves, and when one comes
calling on favors, few dare deny him.
