From the Story
Discovered in Book 3, Chapter 6, Talons and Tea Leaves
"Professor Sybill Trelawney is the Divination teacher at Hogwarts. She is a thin lady, usually draped in a shawl, with very large glasses. She tells the class that she does not often enter the hustle and bustle of the main school, as it clouds her Inner Eye. As she introduces the course, she makes several predictions about students, which leave the class uneasy. She starts the students off reading the tea leaves, encouraging them to broaden their minds in order to see past the mundane. As Harry and Ron attempt to read their leaves, Trelawney snatches up Harry's teacup, promptly dismissing all of Ron's predictions. She predicts danger and an attack in Harry's future, before screaming and sinking into a vacant armchair before announcing that she has seen the Grim in Harry's tea leaves: the omen of death."
