Books.

She LOVED books. And learning. In fact, she loved anything intellectual.

It was for this reason that the Grey Lady suddenly appeared and made her way to the private Ravenclaw-only library tucked away in the corner of the common room. She hovered between two bookcases as she began reading a book on Divination.

Hopefully the Ravenclaw students would take a cue from her and start earning points to take the lead over the slippery Slytherins.
