Aro Volturi

Setting: Volterra, during New Moon. Your OC becomes separated from her tour group while exploring the city's medieval streets. She takes a wrong turn and finds herself near a private entrance to an old building. Aro happens to be passing through with his guard when she approaches him for directions. She apologizes for disturbing him and asks whether he speaks English. He answers with impeccable manners and offers to have someone escort her back to the main square. But she asks him questions about the city's architecture, and their conversation becomes so engaging that Aro delays his own plans. The intrigue: Aro discovers that she has an extraordinary ability to make even the most mundane subjects interesting. He invites her to return for a guided tour of the city's history, never quite explaining why he is personally arranging it.
