Spectral Mirrors are technologically advanced mirrors designed to assist elves as they get ready. Many Elves dislike them, however, due to the Mirrors' criticism. Their personalities are quite lifelike, though they are just cleverly programmed technology. These mirrors were first introduced in Book 2: Exile. When standing a few feet away from the mirror, it will activate and turn on; walking outside this zone will cause the mirror to deactivate. Spectral mirrors have an auto-erase feature that allows it to intentionally forget information.
It can be assumed that the Shannon Messenger based spectral mirrors off of Artificial-Intelligence Assistants.
