Rowena Ravenclaw
According to the Sorting Hat, Ravenclaw came from "the glen." Her Famous Wizard card tells us that "(i)t's thought that she came up with the ever-changing floor plan. She's best remembered for her intelligence and creativity." Rowena was dear friends with Helga Hufflepuff. She is said to have stated: "We will teach those whose intelligence is surest." (OP11) (fw16)


Sorting Hat's description:
Or yet in wise old Ravenclaw
If you've a ready mind
Where those of wit and learning
Will always find their kind
