Harry blinked, dazed as he was transported from the Great Hall to the Room of Requirement. He had been minding his own business, enjoying some treacle tart at dinner when he had disappeared from the bench.
How had that happened? Hermione was always telling them you couldn't apparate within Hogwarts.
He glanced around at an odd assortment of confused looking people. Hermione was there as were Ron, Fred, George, Bill, Charlie, Percy, and Ginny. So were Remus and Tonks, Luna, Malfoy, Angelina, Snape, Fleur, Dumbledore, and a handful of people he didn't know.
Before anyone could react or say anything a piece of paper appeared in the middle of the air in front of them. Everyone regarded it uneasily. Harry looked at Ron in confusion and he shrugged back, looking just as bewildered. Hermione approached the scroll.
"It says: You have all been brought here to meet people from the future and it is essential that you do. You've all been stripped of your wands and time will stand still while you are all here. You will forget everything about this experience, except for a warm feeling that will spur your actions in the war. You will only remember once you are in the future and the people disappear."
Hermione bit her lip and looked up at Harry, perplexed. He shrugged. "At least I can't die from this adventure." He joked. Hermione frowned at him and he smiled to show her he was kidding. He guessed he shouldn't have said that when she knew about the prophecy. Neither can live while the other survives.
He walked over to her and Ron and waited for the time travellers.
"Who do you reckon they'll be?" Ron asked him. Harry shrugged.
"Hopefully friendly people. Although our wands were taken away."
"A nice break from lessons anyways." Ron grinned. Hermione rolled her eyes.
"It said time would stand still Ron. Which means we'll be returned to dinner when this is over and won't have missed any class." Ron didn't look too happy about that.
He opened his mouth to respond but never got the chance.
A gaping hole appeared in the middle of the room. From it, sparkling purple smoke began to erupt in front of everyone who had been gathered in the Room of Requirement. For a couple of minutes, nothing happened. Then there was a loud bang and a whole bunch of teenagers fell in a tangled heap on the floor.
"Oww." Someone groaned. "You're on my stomach."
There were quite a lot of people that had emerged from the future. They all appeared to be Hogwarts age, except for a few that looked a little older. He noted kids of every hair colour and two that seemed darker skinned than the rest.
"James! I told you not to touch it!"
"Don't be a spoil sport Rose. Besides, it's fine. We're just at Hogwarts." The boy who Harry guessed was James gestured to the room and turned around. He gaped as he took in the others.
"Not good." He mumbled as he avoided a bushy red-headed girls glare.
"Just at Hogwarts?" She seethed. "Just at Hogwarts!" She turned to the crowd. "What year is it?"
"1996." Hermione answered in an odd sort of voice. She was looking at the girl as if she knew her but Harry couldn't see how she would.
"Oh yes. Everything fine James. We're just at Hogwarts in NINETEEN NINETY SIX!" Harry paused at the girl's expression. It was one he had seen often on a different witch. He glanced back at Hermione in disbelief as he began to understand.
"Well I'm sorry! I didn't think it would do that! Besides, Roxie's the one who actually touched it."
"Because you knocked me into it!" A girl said from the middle of the throng. They all began to argue over one another, the people from the correct year too stunned to get them to stop. But he couldn't take it any more.
"I'm sorry who are you?" Harry found himself asking the crowd of teenagers in front of them.
Everyone immediately stopped fighting and froze. Most of them avoided his gaze, except for James. He was grinning cockily at Harry, brown eyes alight with excitement and mischief.
"Your children of course."
