Have you ever wondered where the blood that everyone in Bloodborne drinks actually comes from? Someone has a theory, and its kind of gross. It also makes a lot of sense.
- Special blood vials in the game all come from women, such as Arianna, Iosefka, and Sister Adella. We also know that the Healing Church chooses specific women to be vessels for blood and are groomed as Blood Saints. We also know that the person who introduced the entire concept of drinking blood to Yharnam is a ladythe Queen of the Pthumerians.
- One of these women, Arianna, does not give you any more blood when she becomes pregnant. Furthermore, its worth considering that the old lady that you can bring to the church does not give you blood. Menopause?
- The game loves to use concepts relating to the moon and cycles.
- One of Bloodbornes important locations is called The Nightmare of Mensis. There is also a boss called Brain of Mensis (which you have to defeat in order to get an item called Blood Rock.) There is also an item called Mensis Cage, which is used as an antenna that facilitates contact with the Great Ones. Mensis is very similar to the word menses, which is Latin for, well, menstruation. The word also has close ties with the concept of the moon.
