Hogwarts, Gryffindor common room

Challenge: Throughout the common room Ron's unfinished homework is scattered. Each page contains a letter that when combined spell out 3 different words that relate to the Wizarding World and its creatures. Can you find all three? Leave your guess in the comments.

In this interpretation of the Gryffindor common room, I've tried to incorporate as many details as I could. These details include: Ron's homework, the Triwizard cup, an unfinished game of Wizard's chess, a stack of books(one of which includes Tom Riddle's diary with the sock that freed Dobby), Hermione's badge for the S.P.E.W organization, and of course Sirius Blacks visit through the fire.

This build contains over 14,600 pieces and the dimensions are approximately 4ft wide x 4ft long x 5ft high.
