Kitchens
Rotten food, soiled utensils and cook pots caked with mould lay discarded across benches lining the walls. The floor is slick with muck, a huge stone oven with an iron hatch sits to the left of the room and a worn door opens into a large pantry. A set of double doors lead out to the dining hall and a dumbwaiter is stacked with pans and old rotting food, crawling with maggots the size of fingers.
Floor: The floor is slick with muck, smashed plates and cooking ware. Movement can be safely done at half speed or normal speed with a successful Dexterity check.
Stone Oven: Able to fit a large carcass inside its great space roars with hot fire and black smoke. A small metallic rod to one side controls a chimney damper, pulling it would cause great plooms of smoke to begin obfuscating the room. Its heavy iron door would take some effort to open or close and has a lock.
Pantry: A large room filled with shelves of empty hessian sacks, mouldy vegetables and a wooden beam where there are three carcasses hanging by their feet.
Dumbwaiter: Able to be used by a handle crank on the outside of the dumbwaiter to raise up to each floor of the hotel. Each time its used there is a 1 in 6 chance of the rope snapping.
The Chef
A large, bloated troll in a chef's hat and aprpn gorges itself as it prepares meals. Will question any creature what it tastes like. Any creature describing themselves in elaborate, fanciful and appealing language will result in the chef becoming disinterested in them, but simple, conventionally unappealing terms or refusing to answer will result in the chef attempting to capture the creature and stringing them in the pantry for later cooking.
Future design direction may give the chef something the hero's might need, perhaps the chef may be one of the staff characters who have access to keys. I think this room has a potentially hard combat or if clever roleplay encounter. The environment serves as both hinderances (floor) as well as help (stove and smoke) for the clever hero.
