This house was created many years ago by a friendly vampire family (yes, there should be), which also explains the lack of windows. As a servant they have created an awakened and intelligent plant, who has been in their service for decades and is not afraid of the vampires (he has no blood, after all). The house is located in a small grove that is part of a village.
Hooks: Since the vampires are friendly and also very old, they could serve as clients or as a source of information.
Have fun
