A.N from now on I will call the young marauders by first name, the old marauders by last.

Ten minutes later Harry appeared in Dumbledore's office. James turned to look at Harry and his mouth dropped.

"W…W….Who are you?" he stuttered nervously.

"Before you answer Harry, let me ask them a question first." Said Dumbledore. Harry nodded. Dumbledore turned to Peter "You said you found a crystal? Where did you find it? What did it look like?"

"The part of the cave I found it in had a large stone table in it. In the centre was the crystal. This crystal was violet and was about the size of my head. I went to pick it up and the crystal glowed brilliant violet."

"Ah. I think I know what the crystal is. Wait a moment while I check." Dumbledore walked over to his bookcase and pulled out a thin book called "Magical Crystals and Rocks and their Properties". Dumbledore quickly flicked to page 20.

"Ah yes. Here it is. The Jewell of Gemini"

"The Jewell of Gemini?" repeated everyone.

"Yes it clones the person and their belongings and then the two clones live their own lives. Unfortunately for you, you are in a different time to it happened. This does mean though that you can find out what happens in past events without altering the future."

"You mean we can't go back?" asked Sirius

"No you can't"

"So, how many years later are we? Asked Remes

"You are about 20 years after you were in sixth year"

Remus fell into silence looking between Harry and James.

"So what has happened in the last twenty years then?"

"You remember Voldemort?" asked Dumbledore as they all shuddered. They nodded.

"He was defeated about 17 years ago and disappeared. Unfortunately he used a potion to regain a body. That was just over a year ago."

"Who defeated him?" asked James

Dumbledore looked at Harry questionably.

"I don't mean to be rude but are you James Potter, Sirius Black, Peter Pettigrew and Remus Lupin?"

"Yeah. How do you know us?"

"Eh. Dumbledore you should tell them the whole truth.

"Ok Harry. On Halloween 17 years ago Voldemort went to kill Harry. He was unable to do so because his parents sacrificed themselves to save him. This put an ancient protection spell being placed on Harry. He couldn't be touched as long as he was with his family."

"Harry destroyed Voldemort?" asked James in awe.

"Yes he did Mr Potter. When Harry came to Hogwarts he again defeated Voldemort. In the second year he defeated Tom Riddle's Basilisk. In the third he proved his Godfathers innocence. In the fourth he won the tri-wizard tournament and defeated Voldemort yet again. Last year he defeated Voldemort again. That is five times he has defeated Voldemort. More times than anyone else."

"Eh. Why are you telling us this Dumbledore?" asked James

"Look at Harry. Who does he remind you of?" asked Dumbledore smiling.

"He looks like you James. Therefore since it has been almost twenty years I would say that Harry is your son or should I say your clone's son" said Remus

"You are quiet correct Remus" Dumbledore said. James turned pale.

"You mean that I am…my clone is dead?" asked James

"Yes that is so. The only remaining loyal Marauders is Lupin"

"Loyal?" asked James

"Yes loyal. Unfortunately the Pettigrew turned evil."

"Professor?" asked Harry, "How do we know which are the clones?"

"To be honest Harry I do not know."

"You mean that we might be clones?" Sirius asked angrily.

"Yes" answered Dumbledore simply.

"Can we carry on studying?" asked James

"you may, I will put you in Gryffindor as transfer students from America. Remus remember the agreement we made?"

Remus nodded.

"I will let you to use the shack again and with the company of your friends"

Remus opened his mouth to protest. Harry who realised that Remus didn't know that he knew about his werewolf problem bat him to it.

"It's ok Remus. I found out in third year when the old you taught us."

"Thank you Dumbledore" Remus said.

"Right head up to the Gryffindor common room all of you." They all nodded.

As soon as they left the office the marauders broke into talk.

"I wonder what ol' Snivilus is doing now" said Sirius.

"Don't worry you'll find out soon enough" Harry grinned.

The talk carried on about the past until they got to the portrait.

"Shrieking Shack" muttered Harry. The portrait opened and they entered.

"Hang on I'll get my mates, who do know about you, so we can tell them"

Harry went up to the dorm and got Ron. He also picked up the map and the cloak. They headed back down. Luckily Hermione was in the common room still. Harry asked her to get Ginny. When the girls returned Ginny's mouth just dropped.

"t-t-t-two Harrys" Ginny stuttered.

"No Ginny" Harry smiled, "here are the marauders"

"Harry. How is that possible? Only Lupin is left." Asked Hermione

"I don't actually know, but according to what Dumbledore said they found the jewel of Gemini which cloned them. These then ended up here. As they are clones they can know what happened in the last 20 years."

"How did you get the map Harry?" asked James

"I got it from the Weasley twins, who got it from the filches office, who got it off the Black in his 7th year"

"I haven't been in the 7th year yet" stated Sirius

"Ok. So we can tell which one I'm talking about I'll call you by your first name but other versions of you by the last name"

"Seems fair" said James.

"We better go to bed for lessons tomorrow" said Hermione
