You can attach invisible things to objects and then give them to people.
These can be used to keep tabs of course both auditorily and visually.
But then there is that other creepy ■■■■ that saps a person’s intellect, strength, or whatevs you choose to drain from them.
Like a poison necklace or something. It emanates what is bad for the person, like radiation i suppose.
Tell me that ain’t some crazy ■■■■!
Careful of the gifts that you recieve.
