Objects belonging to Godric Gryffindor

There are two objects mentioned in the Harry Potter books that belonged to Godric Gryffindor, the Sorting Hat and the Sword of Gryffindor.

The Sorting Hat is introduced in the first book and it is essential to the placement of the students in the houses. At the beginning of each year, it recites a song in which is included a description of each house, and at times also predictions and warnings. Although it bases the selection of students on the desired characteristics of each house, it also takes into account their choices. It is said that when the founders came across the problem of how the students would be sorted after they had passed away, Godric Gryffindor took off his hat, and into it they each placed a bit of their own brain and personality, and this is how the sorting hat came to be. The sorting hat and the Sword of Gryffindor have a special bond, perhaps because they both belonged to Gryffindor. Although the Sorting Hat was made to catch fire in Deathly Hallows, the bond was still there and the Sorting Hat survived.

The Sword of Gryffindor, which Albus Dumbledore kept in his office, is made of Goblin armour and is silver with rubies and has Gryffindor's name etched on it. The special bond the Sorting Hat and the Sword share is that when it is needed, the Sword can be pulled out of the Sorting Hat. Dumbledore told Harry that this would happen when a true Gryffindor needed it, and Harry pulled it out in the Chamber of Secrets to destroy the Basilisk and Neville Longbottom pulled it out in the Deathly Hallows to destroy Nagini. The Sword only takes in what makes it stronger, and because Harry used the Sword to destroy the Basilisk, the Sword took in the venom and was more powerful against the Horcruxes. Along with Nagini, it was used by Dumbledore to destroy Gaunt's ring and by Ron to destroy Slytherin's locket.
