Book in the Founders' Tower

Founders' book was a book presumably authored by the Founders of Hogwarts School of Witchcraft and Wizardry; Godric Gryffindor, Rowena Ravenclaw, Helga Hufflepuff and Salazar Slytherin. It functioned as an ideas- and sketches-book that the Founders used while creating the School. After the School's creation this book was placed in the Founders' Tower on a writing desk only accessible by the most powerful of students, Harry Potter was granted permission to see it.
