It took both the combine efforts of Harry and Draco to find the reference of Nicholas Flamel in the book they got from Weasel and Granger. It was in the middle of March when they finally found it.

: Flashback:

Harry was sitting at one of the tables in the common room, when Draco ran through the door, "Harry! I found him."

Harry jumped up and grabbed the book from Draco and read, "Nicholas Flamel is the only known maker of the Sorcerer Stone. The stone is believed to be able to turn any pure metals into gold and has the power to make the drinker immortal," Harry looked up at Draco, "this has to be what Voldemort is after. Dumbledore purposely hid it here. He wants me to stop Voldemort, for what I don't know."

Harry thought for a moment before turning to Draco, "Let's go tell Snape. We'll ask him what to do." Draco nodded and both boys left at a run.

The boys burst into the potions classroom and spotted Snape at his desk. The man looked up at the quick entrance. "Can I help you boys?" the man leaned back in his seat and crossed his arms.

"We think Voldemort is after the Sorcerer Stone sir," Draco was panting and leaned onto the desk in front of him.

"Quirrells helping him, I over heard him talking to himself about getting something for Voldemort. It has to be the stone," Harry tried to read the man's expression as he continued, "and Dumbledore has set the whole thing up. He laid out all the pieces and wants me to go after him."

Snape nodded and pulled a familiar mirror out of his desk, "contact your father. Dumbledore has headed for the ministry, most likely to give Quarrel a chance at the stone," he handed the mirror to Harry, "I'll go down the trap door. It's located in the forbidden corridor. Your father has a portkey I created for him, tell him to use it. Were going to need all the help we can get." With that Harry watched as Snape ran from the room before contacting his father.

It took 15 minutes for his father to show up dressed as batman. It turns out his dad and Snape had been in contact a lot during the year. Professor Snape had earned enough trust to learn their secret. Draco however looked confused and Harry told him that it would be explained later. Harry turned to his dad, "should I get into my outfit dad?" Batman shook his head, "No, we don't want you linked to Robin here. It would be too much of a coincidence, our secret wouldn't last a day."

Harry nodded and the trio ran towards the 3rd floor corridor. They saw a door up ahead that was slightly opened. They entered it to see a huge three headed dog sleeping soundly on the floor and a harp playing a lullaby in the corner. "That's a cybrus. My father talks about them all the time, they supposable guard the underworld and music makes them go to sleep," Draco whispered to the two stunned figures in front of him.

Harry followed his father and for the first time noticed a trap door under one of the dog's feet, "look that has to lead somewhere," Harry tried to lift the paw but didn't manage it. He turned to the other to and with annoyance in his voice stated, "are you going to help me or not?"

The trio lifted the paw and inched it over to the side, before pulling open the trap door. They looked down and could only see pitch black. Batman stood up, "I'll go first," was all he said before dropping in the hole. Draco and Harry were looking at each other waiting for a shout to jump, when a huge drop of saliva fell onto Draco's shoulder. Both boys looked up to see three very angry dog heads foaming at the mouth. Harry looked at Draco and the boys jumped down the hole just narrowly missing the very sharp teeth snapping at them.

Harry landed with a thump onto something soft, he looked over to see his father wrapped up in a plant, "dad!" The man smiled and tried to shift. Harry tried to stand to help him but was stopped by a plant tentacle wrapping around his chest. He could see Draco was in the same situation and both boys began to struggle. The plant tightened and it was all Harry could do to breath, so he was forced to stop. Harry went quickly through his mind trying to think of what this plant was, and then it hit him. Harry whipped out his wand and shouted, "Lumos."

Before he knew what was happening. He was falling through the plant onto a cement floor with a thud, followed by two more. Harry groaned and sat up, rubbing the back of his head. Harry looked up at the plant, "well that was fun."

Draco and his dad just glared as the stood. Batman looked over his charge and his friend, "let's just move. No telling how far we still have to go."

Batman of course was right as always. The next challenges were about as much fun as being trampled over by elephants. First they were attacked by winged keys as they tried to catch the one that would open the door to the next room. Then they were subjected to a giant chess set that moved on its own and made deadly attacks when in striking range. During the game the man noticed that the only way to win would be if he made one move. He looked towards his son and Draco who were paling quickly as they noticed it themselves. Before either could protest he moved, "Knight to E5."

The horse he was on moved close to the queen who turned and picked up her sword and rammed it through his steed. Batman fell knocking himself out as he hit the ground. Harry looked at his dad but knew he must finish the game. He walked straight up to the King and said, "Check mate."

Harry rushed over to his dad to see he was out cold. He turned to Draco and said, "you stay here. Try to revive him, I'll go ahead."

Draco looked like he wanted to protest but at Harry's cold look just nodded. Harry walked to the next room ready to face the next challenge.

Inside was a small table filled with vials and a riddle. As he walked closer blue fire sprang up behind him and black fire stopped him from entering the next side. Harry walked up the table and read the riddle there,

"Danger lies before you, while safety lies behind,
Two of us will help you, whichever you would find,
One among us seven will let you move ahead,
Another will transport the drinker back instead,
Two among our number hold only nettle wine,
Three of us are killers, waiting hidden in line.
Choose, unless you wish to stay here forevermore,
To help you in your choice, we give you these clues four:
First, however slyly the poison tries to hide
You will always find some on nettle wine's left side;
Second, different are those who stand at either end,
But if you would move onward, neither is your friend;
Third, as you see clearly, all are different size,
Neither dwarf nor giant holds death in their insides;
Fourth, the second left and the second on the right
Are twins once you taste them, though different at first sight.
"

Harry looked at the vials before him, breaking the riddle down he discovered that the first, fourth, and fifth one was defiantly a poison. Two and six were nettled wine and the 7th one would take him backwards. That left only the third vial and the smallest to take him forward. Harry took a gulp and then headed through the flames.

On the other side of the fire Harry was met with the site of Quirrell standing above Snape as the man withered on the ground in pain, " you should never have denied your master Serverus. When he is reborn I will be rewarded but you will be killed. The time to redeem yourself in his eyes is here, tell me how to get the stone from the mirror."

Snape spat at Quirrell, "No."

As Quirrell raised his wand again Harry ran and tackled him. The wand flew through the air and Harry scrambled to get to it first. His actions were in vain as Quirrell pulled on his leg tripping him up. The man reached the wand first and pointed it at Harry. Ropes shot out of his wand tying him up and repeated it for Snape.

Quirrell then sheathed his wand and turned to the mirror, murmuring to himself. "I see my self holding the stone, but how do I get it?" It was then that a voice not Quirrells spoke, "Use the boy."

The ropes around Harry dropped, "come here Potter," Harry shuffled forward and Quirrell pushed him in front of the mirror, "tell me what you see."

Harry looked into it and nearly gasped inside he saw himself but the mirror version of him smiled and smirked at him. The mirror him looked over in the corner and Harry saw the mirror version of his dad 

step out. He placed his hand in his pocket and drew out a red stone and handed over to the mirror Harry. The mirror Harry placed it in his pocket and at the same time Harry felt a weight in his pocket. Harry almost jumped when a voice said, "Well what do you see boy?"

"I-I see the Slytherin house winning the house cup," Harry said as quickly as he could make up. The mysterious voice spoke again sending shivers down Harry's spine, "Let me talk to him Quarrel, face to face."

Harry inched away from the man who stood arguing with the voice. Finally the voice won out and Harry watched fascinated as the man unwound the turban. Harry wanted to run as fast as he could but was glued to the spot. Looking over Harry could tell Snape was too, before turning back towards Quarrel.

The turban fell away and revealed a face on the back of Quarrel head. The face had red eyes and slits for a nose, and it was staring straight at Harry. "Harry Potter," Harry bristled but didn't say anything as the voice rasped on, "look at what has become of me. I am nothing more than a spirit that leeches off others, but tonight I will be reborn. All that I need is that stone in your pocket."

Harry's eyes widen and he ran from his spot. The voice shouted, "Seize him."

Harry was tackled to the ground landing painfully on his back as he twisted through the air. He put his hands up to push Quarrel away and a scream echoed through the chamber. Harry looked up to see part of Quarrels face burned, looking down at his hands he quickly jumped up and grabbed the other mans face. Screaming cut through the air until the older wizard's body was nothing but ash. Harry watched as Voldemort's spirit escaped the dying body, and ran through him.

Harry screamed and fell to the floor clutching his head. His eyes were bleary and he felt weak, but he managed to stand. He walked over to Snape and helped pick him up when a noise behind him had him turning. There in front of the flames was Albus Dumbledore and by the looks of his face he was angry.

What happened next shocked Harry and Snape to the core as Dumbledore raised his wand and shouted, "Advara Kedavra." Hands pushed Harry down nearly missing the green light. Harry looked up just in time to see a black shadow tackle the old man to the ground. Harry could barely conceal the smile on his face as his father beat the old man senseless. Harry's eye's blurred and he passed out.
