A small mansion, one of many in an affluent street of a small village. The house has a grand entrance with a wide staircase leading to the upper floor. There is a dining room, a small living room and a kitchen. Upstairs a study and two bedrooms. In the cellar, a storeroom and a coal cellar connected to the sewage system by a secret door.
Hooks: The house could be used for someone to be kidnapped and the characters have to rescue the person. Or the characters themselves live in the house and are attacked by creatures from the sewers.
