Palm-tells you about Past, Present, and Future.
Tarot cards- tells you about relationships, people, places and things.
Crystal Ball- tells Clairvoyant, Clairaudient, Dream interpretations, and also helps you tune into any Psychic abilities you might think you have.
Ancient runes - tells you about dates. times , places, and warnings.
They are specifically about the person I am reading, But..if this person chooses to they may name a person, give me their date of birth, and the runes will give them all info on the person they asked about. (It is always helpful if you have a picture/item belonging to this person at time of reading)
Thus this is the reason people may choose to have more then one area and or topic in their readings done for them.
