I’d completely forgotten about World of Darkness’s Ghouls. Thanks to CyborgPuppy for reminding me.
That would be on a short list of campaigns that I’d run for others with a very strong D/s theme.
A troupe of two or three ghouls blood bound to a vampire Master who views them as expendable playthings. He assigns them tasks, indulges in depraved orgies of blood and degradation, and generally leads the debased life of a posh vampire.
All the while they a trying to do everything they can think of to make him happy and complete his goals. Its basically like the Apprentice but with more sex..
