I don't really have a name, but they begin to appear after something starts to question reality They appear as a burnt and wounded ghost of the host, and they only appear as the host starts losing focus. They have the ability to change the temperature of the object they touch. Most have a mischievous nature, somewhat like Grayscale, although some are the opposite. They cannot directly interact with the host. They disappear as soon as the host refocuses. They can pick up and interact with anything but silver objects (for reasons). If they touch silver, they're eradicated from the person's mind and the host can never get one again.
They occasionally pick up radio waves and other signals. I don't have art yet, because no motivation and no drawing device so
