I started out with this idea and it hit me in the noggin. This is the backstory of what I call "The Alexis/Bellatrix series".
Alexis is a girl who feels like she's free to roam around..... except that she is not free. When she finds a mysterious room filled with 10 beautiful women, she realized something: all of them were killed by a spirit in the same place that she is in now.
Bellatrix is the one who keeps Alexis under lock and key, making sure that she doesn't escape. She wants to break Alexis once and for all...... for good.
Now knowing the truth, will Alexis finally break free? Or will Bellatrix finally break her?
