Summary: This starts in 1995. Near the end of Harry Potter's fourth year. No TriWizard Tournament. One day, a girl the same age as Harry suddenly appears at Hogwarts with no memory of her life. She only remembers her name and her birthday. Plus, she has the gifts of Intangibility and Thought Projection. With Intangibility, she can change her molecule structure in order to pass through walls, people, and objects. With Thought Projection, she can bring fictional, inanimate objects to life. Because she has no memory, Dumbledore offers her a home at Hogwarts. Fred Weasley then takes an interest in the girl.
