Alastor "Mad Eye" Moody, was a rude, paranoid man of unknown years.

And from so many years, had obviously had a heap of injuries to come with it. No one thought he was approachable, even his own sister had a little tint of fear everytime she had to talk to her brother in person, not via letter or Patronus. Yet, there seemed to be a sort of advisory tone to his rough, time worn voice. You, a longtime member of the OOTP since the First Wizarding War, had found a certain polaroid photograph in a drawer, hidden in the picture album of Alastor, which had slipped out while you walked by. It had a woman in it, moving. In the photograph, at first, she was looking away, as if waiting for somebody. Then, as the camera (or, whatever was used to take magic pictures) got closer, she turned to the lens, smiling. Her hair was the colour of a midnight sky, her eyes elegant, large and emerald green with hints of sapphire, her cheekbones high and her skin a milky white.

You asked Moody about it, of course. What mysterious lady would reside in his books?

"Minerva."
