Harry turned towards the plain black door. After months and months of dreaming about it, he was here at last.
“Let’s go,” he whispered, and he led the way down the corridor, Luna right behind him, gazing around with her mouth slightly open.
“OK, listen,” said Harry stopping again within six feet of the door. “Maybe… maybe a couple of people should stay here as a—as a lookout, and—”
“And how’re we going to let you know something’s coming?” asked Ginny, her eyebrows raised. “You could be miles away.”
“We’re coming with you, Harry,” said Neville.
“Let’s get on with it,” said Ron firmly.
Harry still did not want to take them all with him, but it seemed he had no choice. He turned to face the door and walked forwards… just as it had in his dream, it swung open and he marched over the threshold, the others at his heels.
They were standing in a large, circular room. Everything in here was black including the floor and ceiling; identical, unmarked, handleless black doors were set at intervals all around the black walls, interspersed with branches of candles whose flames burned blue; their cool, shimmering light reflected in the shining marble floor made it look as though there was dark water underfoot.
“Someone shut the door,” Harry muttered.
He regretted giving this order the moment Neville had obeyed it. Without the long chink of light from the torchlit corridor behind them, the place became so dark that for a moment the only things they could see were the bunches of shivering blue flames on the walls and their ghostly reflections in the floor.
In his dream, Harry had always walked purposefully across this room to the door immediately opposite the entrance and walked on. But there were around a dozen doors here. Just as he was gazing ahead at the doors opposite him, trying to decide which was the right one, there was a great rumbling noise and the candles began to move sideways. The circular wall was rotating.
Hermione grabbed Harry’s arm as though frightened the floor might move, too, but it did not. For a few seconds, the blue flames around them were blurred to resemble neon lines as the wall sped around; then, quite as suddenly as it had started, the rumbling stopped and everything became stationary once again.
