In chapter 13 of Book 4, Professor Trewlaney sets the divination class
at constructing charts that show the position of the planets at the
moment of each student's birth, to show how this influences the life of
each of the students. During this activity, Lavender Brown states that
her chart includes an unaspected planet, the identity of which
Professor Trewlaney confirms to be Uranus.

What does the influence of Uranus mean, in astrology? What does Uranus'
influence mean when it is unaspected? How do we see these
traits/qualities in the personality of Lavender and in the things that
happen to her throughout the series?
