The fact that we even have this piece is purely coincidental. It holds the presence of one of the oldest types of entities to exist on Earth. She is known as the Jorogumo. In spirit form, she takes the form a beautiful woman. She is usually described as a ghost, but it is her spirit form. In the physical, she takes the form of a spider. One bit from the Jorogumo and she inhabits your mind and makes you do the things that she wants you to do.
This piece holds the spiritual presence of the Jorogumo. The word is Japanese, but don't be fooled. These creatures live all over the world. I caught this one in my sister's house in the bathroom. She's terrified of spiders, so she called me to catch it. Turns out, we have something metaphysical on our hands. Of course, I didn't tell her. I simply conjured the presence of the entity into this piece.
The powers of the Jorogumo will allow you to invade another peron's mind. You will be able to enter their thoughts and control them. You will be able to do this by sitting alone in a dark room, meditating and envisions the person whose mind you wish to enter. You will the convey the message of what you want them to do.
