It was late at night when the common room was almost empty and Nagini was back from Slughorn's party when Nagini began her written homework. She whispered her answers to her quill, watching it zoom across the page.
She had had some fun at the party. Although she had no idea who most of the famous witches and wizards who attended were, it was quite nice there, especially with Voldemort. She did not feel like she was going to make many friends here, but it didn't quite matter to her.
She had only just finished when Voldemort had slid into the common room.
"What are you here for?" she asked.
"Only passing, want to come?" he asked, smirking slightly.
"Where?"
"You'll see."
He led her up stair after stair until he stopped at a blank wall. "Just think, I want to know where this leads as hard as you can."
She was confused, but obliged. Suddenly, a large ornate door appeared and they walked in.
It was the strangest room she had ever seen. It was dark and ornate with a single bookshelf at the end.
"The Room of Requirements," he said.
She suddenly saw the titles of the books.
Horcruxes.
