Spectral Mirrors are technologically advanced mirrors designed to assist elves as they get ready, but many dislike their criticism. They ran a bit out of style for a while. They are known to be very lifelike even though they are just cleverly programmed technology. They were first introduced in Book 2: Exile. When standing a few feet away from the mirror, it will activate and turn on. The same works for turning it off. Spectral mirrors also have an auto-erase feature that can be used to intentionally forget information.
It can be assumed that the Shannon Messenger based spectral mirrors off human Artificial-Intelligence assistants.
