Rowling also imagined a supporting cast of adults. The headmaster of Hogwarts is the powerful, but kind wizard Albus Dumbledore, who becomes Harry's confidant. Rowling described him as "epitome of goodness". His right hand is severe Minerva McGonagall, who according to the author "under that gruff exterior" is "a bit of an old softy", the friendly half-giant Rubeus Hagrid, who saved Harry from the Dursley family, and the sinister Severus Snape. Professor Quirrell is also featured in the novel.
