The torn paper corner shows part of a design of a winged horse - no, a unicorn, with a rider.
There is a poem on the top page of the stack, or part of one, being recited by a character in the book.
....the sun with its brightness,
And the snow with its whiteness,
And the fire with all the strength it hath,
And the lightning with its rapid wrath,
And the winds with their swiftness along its path,
And the sea with its deepness,
And the rocks with their steepness,
And the Earth with its starkness
All these I place by God's almighty help and grace
Between myself and the powers of darkness.
