The Count cannot eat, appear in reflections, suffer the presence of holy images for more than one scene, physically manipulate his Guests nor command his Manservant to do so on his behalf.
The Count can provide any manner of food, drink or gifts within reason (such as clothes, jewelry and other amenables). The Count may also excuse himself from any scene and eavesdrop unbeknown to the Guests.
The Guests cannot be openly insulting or excessively vulgar to one another or their host (it is openly insulting to accuse your host of being a vampire or suggesting his taste is decor is creepy). The Guests cannot physically interact with the count, nor his manservant without forfeiting. The guests cannot excuse themselves from the Count's presence without the Manservant in attendance, or, if neither are present, must remain where they have been situated.
Guests may make modest requests of their host, but nothing rude or overly demanding (gifts are given, not ordered). Guests may smoke and gentlemen may remove their hats and coats.
