You are sitting at your desk in Dumbledore's office. Hermione is standing outside your office door, knocking, presumably with some grievance against faculty or Slytherin. Having been transported here by some accident of magic, in the form of Professor Dumbledore, you have taken on the task of undermining Hermione's reputation on behalf of your new friend, Professor Snape.
You look around your office. A Phoenix, apparently named Fawkes, sits on its perch looking miserable. A fire burns in the corner, and outside the window, you can see students circulating in the open quad in the early morning light, socializing before classes begin.
Training for Hermione could be done personally by purchasing favors, or by sending her on contrived "missions" that would serve to lower her reputation with other students. Some favors and missions might require more coaxing, or time, for Hermione to find acceptable. The currency for these tasks is House Points.
Hermione knocks again, impatiently, waiting for you to call her in.
