My overall "idea" is this:
MC is a misc embodiment of those who dwell in the manor before the arrival of your characters. A mom and her 2 daughters, who recently inherited the place after having no knowledge of it for several generations. Its a creepy place, but the inside feels quite welcoming and is surprisingly upkept.
Considering none of you have been here before, have ever seen it, and have no knowledge of it even existing, something about this place feels...familiar. The Eldest Daughter goes exploring and is lead into the basement where she finds a book. Most of it cant he made out, but what she does read is a little about the house, the family history, and a surprising secret that their bloodline was "pure" for several generations, those who dwelled here kept things "within the family" and those who did not were shunned and outcasted, yet now the bloodlines reconnect and the house has a new owner.
MC will begin displaying itself in dreams, voices, whispers, easily corrupting the Eldest who gives into curiosity and "drinks the kool-aid" and begins serving MC into corrupting her younger sister and mother into the old ways of the house. Yet to continue the bloodline, they all must carry a child.
Which means one of the following must happen:
A-Mc can impregnate somehow
B-we add a son to the character pool. One of you playing Daughter and Mother, another playing son and daughter, you can decide who wants eldest daughter, or youngest daughter. Maybe the son is between them in age
Or C- the eldest daughter gets turned into a futa via the power Mc possessed
For anyone still interested, let me know and let's work something out
