Harry and the turtles and their friends were in the unused classroom practising their ninja skills. The sword of Tengu had been kept safe in the lair after what happened last week. Sense then, Neville and Luna and Stephen and Padma had really improved their skills.

Harry looked out the window as he thought about the sword. He wondered where it came from.

"Wherever the sword came from, it's best we keep it safe." He said.

"You worry too much Harry." Said Leo. "You need to take it low for now."

"Say Luna." Said Raph. "Where'd your shoes go?"

He was right. She wasn't wearing any shoes.

"It's the nargles. They like to hide things from me. But they come back once in awhile."

"Uh. Okay." Said Don. "And I thought Mike was wired."

"Hey!" Mike shouted taking offince.

"Alright. Let's call it a night." Harry said as he got ready to leave.

It was almost past curfew. And they had relocated to the third floor after Malfoy had found them.

Of course, Mike heard a growling from a door not too far away from them. What was it?

"Whatever it is, I better go and see."

Before he aprotched it, Raph grabbed his sholder and pulled him back.

"Mike what are doing?! You know we can't go in there!"

"Don't you hear it Raph? Something is in there."

"Which is what Professor Dumbledore is forbidding us from seeing. If you go in there, Harry could get expelled."

"Well what ever is in there can't be worse than that."

"What's going on here?" Leo asked as he and the others walked by.

"Leo. Tell Mike we're not aloud in that corridor." Raph said to him.

"Well I don't care! I'm seeing what's in there!"

Before anyone could stop him, Mike pushed Raph onto Leo and kicked down the door to the forbidden corridor.

"Mike! No!" Harry shouted.

"Hold on." Said Hermione. "Listen."

They can hear music. A flute. They walked inside to see what it was. Mike was seen playing a flute and in front of him was a giant dog with three head relaxing to the music before dropping to sleep.

"Uh, what the shell just happened?" Don asked.

"Haven't you seen any monster movies?" Mike asked. "Music is the one way to calm down a Cerberus."

"Are they crazy?" Stephen asked. "What in the world are they thinking keeping a thing like that in a school?"

"Are you not using your eyes?" Hermione asked. "It's standing on a trap door. Aparently it's guarding something."

"Guarding something?" Mike asked. "Just like in those late night horror movies?"

"Uh. What?" Padma asked.

"Well, I'm gonna have a look." Stephen said as he walked to the trap door.

"Wait." Said Leo. "Don't open it. It could be something dangerous."

"Or something valuble." Said Mike. "Or both."

"Well...alright. I'll look."

"No!"

Too late. He opened the door and then fell down a pit.

"Stephen!" Raph shouted as he jumped in after him.

"Cowabunga!" Mike shouted as he jumped in next.

"Guys wait!" Leo shouted just as the others followed down as well. "It's tough being a leader."

With that said, Leo was the last one to jump down the trap door.

They fell a long way down and then landed on some vines.

"Everyone alright?" Raph asked.

"I'm fine." Said Neville. "Lucky these plants things were here."

"Don't move." Said Hermione. "This is Devil Snare. If we move it'll whap vines all over us and kill us."

"Oh great. Just what we need." Said Stephen.

"Don't move."

Mike wasn't paying attention to what Hermione was saying but kept still. By then, the vines moved and all of them slowly went down to solid ground below them.

"See? that was easy." Hermione said smiling.

"Right." Said Raph. "Hey. Do any of you hear a flapping sound?"

The team walked to the next room. Inside was floating keys with wings.

"Did I ever tell you that magic is both awsome and weird?" Don asked.

"I bet one of those keys fits that door." Said Leo.

"Over there!" Mike shouted as he pointed to one of the keys. "That's it! The one with the broken wing!"

"I got it!" Padma shouted as she pulled out a grapple hook and tossed it to the key. And then she pulled it down to her and walked over to the door and unlocked it.

By then, they walked into the next to try and find a way out.

"Oh no. I hate graveyards." Said Mike.

"You watch way too many monster movies." Said Leo.

"Wait." Neville said as he looked at the tombstones. "This isn't a graveyard. It's a giant wizards chess board."

"Wizards chess?" Don asked.

"Unlike muggle chess, you have to tell the peaces where to go. And they even attack each other to take anothers place. When the game is over, they'll rebuild themselves and return to their starting points."

"I've got their peaces right here!" Raph shouted as he pulled out his sies and charged at the white peaces.

"Raph wait!" Harry shouted.

But Raph didn't listen as the white pomes tried to block his path with their swords. But of course, Raph leaped over them and the other peaces tried to get him. Until Raph grabbed the white kings sword and smashed him with it as the king fell down. By then, the other peaces retreated and let the others pass.

"Raph. What the shell?!" Leo shouted.

"Hey I got us past didn't I?"

By then, they walked down a staircase to a dead end. All they could find was a mirror.

"That's it?" Stephen asked. "This is what we all came down here for? A mirror?"

Harry walked closer to it. On top of it was text that said,

Erised stra ehru oyt ube cafru oyt on wohsi.

Harry looked at himself in the mirror. Beside him were not his friends or his brothers. But two other people. Two he didn't even know. One of them was a lady with red hair and the other looked like an older version of Harry. Until,

"Mum? Dad?"

"Harry?" Leo asked.

Could they be Harry's parents. No. It can't be true.

By then, Harry saw his mother give his hand a red stone. And then the real Harry felt something on his hand. It was the same stone.

"Harry what is it?" Mike asked as he walked and Harry's parents vanished.

"Look in this properly." Harry said as he stepped aside.

"Whoa." Said Mike. "I'm in a room full of pizza. Everything's made out of pizza. The walls. The floors. Everything. Cool. Does this mirror show the future?"

"Mike that's impossible." Said Raph.

"I know."

The team jumped. Dumbledore was there behind them.

"Professor." Said Hermione. "It's not what you think. We were lost."

"And you were lost." Said another man who walked in. "Hello Harry Potter. I am Nicolas Flamel. I see you and your friends have discovered the delights of the Mirror of Erised."

"Is that what it's called?" Harry asked.

"Yes. By now I trust you know what it does?"

"It shows the future." Said Mike.

"Ha ha. No my friend. This mirror was crafted in the late 19th centuary. It shows us nothing more than the deepest desires of our hearts. Unfortintently, this mirror give neither truth or knowledge. Men have wasted away from this amazing mirror. Some were even driven mad."

"Ah man." Mike said dropping down.

"Harry." Nicolas said to him. "On your hand. That's the Philosopher's Stone. It'll turn any metal it touches into pure gold. And it preduces the Elixir of Life. A powerful potion that makes you imortal. Meaning you can never die. I crafted this in the medival."

"So, you're alive forever?" Harry asked.

"Right. I thought I could have Dumbledore hide it here in case some of the dark lords followers were gonna steal it which I was right."

"But alas, I don't want to risk endangering the students with it here." Dumbledore explained.

"Well...we could fins a new place to hide it." Said Mike. "Like the lair maybe?"

"Mike. No way." Said Raph. "You really think hiding that thing in our place is a good idea. Any of Voldemort's followers could find the lair as well."

"Hold on. I think Mike has a good idea for once." Said Leo. "Remember? Dumbledore had placed wards around the lair to keep the death eaters from finding us. Could the ward hide the stone as well?"

"Yes. The ward will be upgraded to keep the stone safe."

"Well okay then." Said Raph. "Hopfuly it'll work."

"Quirrell you idiot!" Voldemort shouted at him. "You have waited for too long! Now Dumbledore is removing the stone from Hogwarts!"

"Master I had no idea how to get past that beast of Hagrid's!" Quirrell shouted back.

"Whatever! We must find the stone if I'm to get a body back!"

"It could be anywhere."

"Where?"

"Like New York City."

"Of course. New York City. One of best alies is there. Quirrell. Send word to him and we'll go to him this weekend."

"What is his name?"

"He has power that matches mine. We are both the most powerful beings on this planet. His name...Oroku Soki."

Authors note:

Yeah, I left out the troll and Snape's riddle because I couldn't think of how to have them included for the turtles. Besides, the movie didn't have them eather. This may not be the best but it's what I got for the stone to be included. And yes the stone will be safe from the wards around the lair.

The next chapter is up and you'll find out how Voldemort knows The Shredder.
