Chapter 11 into the Pit.

It was a few weeks later, and Jack was sitting alone in the dormitory, when his computer screen turned on and Daniel's face appeared. "Jack, I solved another riddle." Jack just nodded as Daniel went on. "You need to beat the snake guardian of the Chamber of Secrets. I've also got a detailed map of how to get to the chamber from the Great Hall." As he finished a map appeared on the screen. Jack jumped up and grabbed his gear and walked out of the dormitory.

Within moments he stood in front of the sink in a girl's bathroom that lead to the chamber below. "So this is the way into the chamber," said Jack to himself.

Suddenly, a voice from behind him said, "You can't get in there, it's all sealed up."

Jack spun around, Zat gun drawn only to see a girl ghost. "Well, I have my own ways of getting the door to open." Jack reached into his vest and pulled out some of C4. After carefully placing the charges he backed off and with a flick of the switch a loud bang filled the air along with smoke. Jack walked up to where the sink used to be and saw that his plan had worked. A rather wide tube lead down into the darkness. Suddenly, he heard voices from outside the door.

"What was that Finch?" cried the voice of Professor McGonagall.

"It came from within the bathroom," answered Finch. They both opened the door just in time to see someone jump down the hole leading to the chamber.

"Stop!!" yelled McGonagall into the hole. "Finch, go get Professor Dumbledore. I'm going after him." As Finch ran to get Dumbledore, McGonagall jumped down the hole after Jack.

When Jack reached the bottom of the very wet tunnel he raised his P-90 and turned on his flashlight. He grabbed his radio. "Odyssey, do you read me? This is Colonel Jack O'Neill, do you have a transporter lock?" asked Jack, after a few seconds

"This is the Odyssey, Colonel we are reading you loud and clear. We have a good lock on your position." With that, Jack started walking fast, but stealthily, down the tunnel. Shortly he came across what looked like a cave, and he had just gotten to the other side of the cave when he heard footsteps coming behind him.

He spun around only to see light coming towards him. "Stop right there!" yelled McGonagall. Without saying anything, Jack took off in a dead sprint down the tunnel, spells flying by him. As he turned the corner, he came face to face with a huge door covered with snakes. As Jack ran to the closed door, he pulled out a piece of C4 from his vest. He slammed it on the door and ran for behind a nearby pillar. He pushed the button and the tunnel filled with smoke as the door blew opened. McGonagall turned the corner to see the doors to the chamber open. She walked toward to the door, but soon felt a knife on her neck.

"I don't want to hurt you Professor," said Jack as he activated his Zat gun with his spare hand. "Put down the wand before you leave me no choice."

"Mr. O'Neill, is that you?" asked McGonagall calmly as she dropped her wand.

"It's me," replied Jack as he pulled the knife away. McGonagall turned around to see the student wearing what looked like a muggle military uniform and pointing a weird looking gun at her.

"Mr. O'Neill, give me that weapon and you won't be expelled," said McGonagall as Dumbledore rounded the corner wand drawn.

"Colonel O'Neill, I won't recommend shooting my staff," said Dumbledore as he lowered his wand.

"Sorry, Professor, but she was trying to stop me from getting those ZPMs," said Jack as he lowered his Zat gun. McGonagall was confused to say the least.

"Dumbledore, what do you mean by calling this boy a Colonel?" asked McGonagall.

"This is Colonel Jack O'Neill from Stargate Command," said Dumbledore. "I asked him here in order that he help provide protection for Harry."

"You can't be serious, this boy is a muggle and in their military?" said McGonagall.

"I'm not a boy, I'm almost the same age as you," said Jack, making McGonagall's eyes wider.

"Well," he corrected, "my older self is about your age."

"The Colonel O'Neill you see here is a clone of a General O'Neill and Colonel O'Neill has all the memories of his older self," explained Dumbledore. Dumbledore and Jack went on to tell McGonagall all about the SGC.

"So, you're telling me he is really the alien clone of a man that's saved the Earth from aliens, and that he needs to get into Merlin's tomb?" asked McGonagall.

"That's pretty much it," replied Jack. "Now, can we please find that sword, I'm getting kind of tired." Jack walked into the Chamber followed by the two teachers.

The chamber was big to say the least, and had the look of a dark, ancient tomb. Lying in the middle of the Chamber was the decaying body of a giant snake. "Professor, come take a look at this," called Jack as his flash light fell on a sword. The sword looked almost the same as Gryffindor's, only darker in color. Jack reached slowly over and grabbed the sword, but the moment he touched the sword the whole chamber started to cave in. "We have to get out of here now!" yelled Jack as he grabbed his radio "Odyssey, this is Colonel O'Neill. Lock onto me and the two other life signs and beam us to Hogwarts beam location 3, now!" Just as water started to flood the chamber the three of them disappeared in a flash of light and reappeared in the still dark Great Hall.

"What was that?" cried McGonagall. "Well Professor, we were just beamed by the starship Odyssey to the Great Hall. Now that I have what I want, please excuse me. I have to get back to my room before I'm missed," said Jack as he looked at his watch and say that it would be morning shortly.

"What do we tell Finch?" asked McGonagall as Jack walked away. "It seems that we will have to change Finch's memory, and ban entrance into the girl's restroom again," said Dumbledore. Jack ran up the stairs to the portrait, quietly said the password, and walked into the common room. Luckily, it was empty and he ran up the stairs to the boy dormitory. He walked up to his trunk and dumped his gear and the sword into it. He just had it closed when Ron got up to use the restroom.

"Two down, Two to go," said Jack to himself.

I have made a major change. I have changed the season that it happens in form 8 to 9 so that the Ori can come into the frame. If it makes you mad sorry. Now here is a clip from the next chapter Christmas Time

"Hey, Neville what are you doing here?" asked Ron. Neville looked down scared, when another lady in a wheelchair came up
