“Ron!”

“Ron!”

“Hermione!”

He had a confused impression of colored hangings, of lamps and many faces. The next moment, he, Ron, and Hermione were engulfed, hugged, pounded on the back, their hair ruffled, their hands shaken, by what seemed to be more than twenty people. They might have just won a Quidditch final.

“Okay, okay, calm down!” Neville called, and as the crowd backed away, Harry was able to take in their surroundings.

He did not recognize the dorm at all. It was enormous, and looked rather like the interior of a particularly sumptuous tree house, or perhaps a gigantic ship’s cabin. Multicolored hammocks were strung from the ceiling and from the balcony that ran around the dark wood-paneled and windowless walls, which were covered in bright tapestry hangings. Harry saw the gold Gryffindor lion, emblazoned on scarlet; the black badger of Hufflepuff, set against yellow; and the bronze eagle of Ravenclaw, on blue. The silver and green of Slytherin alone were absent. There were bulging bookcases, a few broomsticks propped against the walls, and in the corner, a large wood-cased wireless.

“Where are we?”

“Room of Requirement, of course!” said Neville. “Surpassed itself, hasn’t it? The Carrows were chasing me, and I knew I had just one chance for a hideout: I managed to get through the door and this is what I found! Well, it wasn’t exactly like this when I arrived, it was a load smaller, there was only one hammock and just Gryffindor hangings. But it’s expanded as more and more of the D.A. have arrived.”

“And the Carrows can’t get in?” asked Harry, looking around for the door.

“No,” said Seamus Finnigan, whom Harry had not recognized until he spoke: Seamus’s face was bruised and puffy. “It’s a proper hideout, as long as one of us stays in here, they can’t get at us, the door won’t open. It’s all down to Neville. He really gets this room. You’ve got to ask for exactly what you need – like, ‘I don’t want any Carrow supporters to be able to get in’ – and it’ll do it for you! You’ve just got to make sure you close the loopholes. Neville’s the man!”

“It’s quite straightforward, really,” said Neville modestly. “I’d been in here about a day and a half, and getting really hungry, and wishing I could get something to eat, and that’s when the passage to Hog’s Head opened up. I went through it and met Aberforth. He’s been providing us with food, because for some reason, that’s the one thing the room doesn’t really do.”

“Yeah, well, food’s one of the five exceptions to Gamp’s Law of Elemental Transfiguration,” said Ron to general astonishment.

“So we’ve been hiding out here for nearly two weeks,” said Seamus, “and it just makes more hammocks every time we need room, and it even sprouted a pretty good bathroom once girls started turning up – ”

“ – and thought they’d quite like to wash, yes,” supplied Lavender Brown, whom Harry had not noticed until that point. Now that he looked around properly, he recognized many familiar faces. Both Patil twins were there, as were Terry Boot, Ernie Macmillan, Anthony Goldstein, and Michael Corner.

“Tell us what you’ve been up to, though,” said Ernie. “There’ve been so many rumors, we’ve been trying to keep up with you on Potterwatch.” He pointed at the wireless. “You didn’t break into Gringotts?”

“They did!” said Neville. “And the dragon’s true too!”

There was a smattering of applause and a few whoops; Ron took a bow.

“What were you after?” asked Seamus eagerly.

Before any of them could parry the question with one of their own, Harry felt a terrible, scorching pain in the lightning scar. As he turned his back hastily on the curious and delighted faces, the Room of Requirement vanished, and he was standing inside a ruined stone shack, and the rotting floorboards were ripped apart at his feet, a disinterred golden box lay open and empty beside the hole, and Voldemort’s scream of fury vibrated inside his head.
