The Hall of Empty Melodies is a large room in the Castle That Never Was, located in The World That Never Was. A large platform makes up the room with large walls facing eitherside of it. Several primary events happen here in the final battle involving Sora, his companions and the surviving members of Organization XIII. Sora, Donald and Goofy encounter Saix here who informs them that their role is no longer needed due to the finalising of Kingdom Hearts. He summons Heartless to destroy them. Kairi suddenly appears on an overhead balcony, and leaps down with Riku in the form of Xehanort's Heartless to help Sora. Maleficent and Pete also arrive in the castle.
Xigbar eliminates all of the Heartless so he can take on Sora himself, but the following battle ends with Xigbar dying. Sora, Donald and Goofy head off to the upper level of the room where Sora has an emotional reunion with Kairi and Riku. Sniper and Assassin Nobodies appear during navigation through the room.
