A Seer who uses the stars to tell the future.
Caption: "The stars foretell... I need a change in wardrobe!" This character is a pretty old staple in fiction. The Astrologer is a Seer who frequently is also a Fortune Teller and Court Mage, though is just as likely to be a hermit who studies the stars in solitude. The nuts and bolts of their skill is to interpret future events based on the position of stars and planets, often using big heaps of Symbolism to link characters and events with astrological bodies and movements. However, as something open to interpretation they may anger clients when they make wrong predictions or have unfavorable fortunes. This especially true when they serve a villain who may kill them for the failure or as bearer of bad news. Astrologers can be good guys, neutral, self interested, or evil. In fact, a story may have two Astrologers who engage in Scry Versus Scry to see which can affect their vision of the future. In modern non-fantasy stories, the astrologer is usually a fake, whether they will admit it or not. The astronomer may or may not use the Western Zodiac or the Eastern Zodiac, instead substituting a vaguely defined astrological system of meaning. This last one is especially common in fully original fantasy settings. If they do use a zodiac of some sort, they may also happily engage in matchmaking, whether they're asked to or not. The Astrologer is not to be confused with an Astronomer, while both study the stars the latter does so with science in mind. Anime and Manga
