Divination is the art of predicting the future. Various methods are described, including crystal balls, palmistry, tea leaves, cartomancy (including the reading of playing cards and the Tarot), astrology, and dream interpretations. Divination is described as "one of the most imprecise branches of magic". Supporters of the subject claim that it is an inexact science that requires innate gifts. Those opposed claim that the subject is irrelevant and fraudulent.
