Looking glass

A looking glass is a mystical item that possesses various properties. Such things may take the form of enchanted mirrors or crystal balls. They are used by magic users, whose abilities enable them to divine mystical insight by analyzing the glass. In at least one instance, a young blonde-haired girl found herself pulled through a looking glass and dropped into a strange worlds of axe-wielding playing cards, invisible cats, and pot-smoking caterpillars.
