**A/N: This section is the forming of the bridge between the two worlds, and when we come back to "Modern Day". It is the original SG:1 and many of the events in the HP series had not occurred yet (the passing of two particular men). I won't give an exact pinpointing of time, but there is the general idea. Also, I play with point of view here. It begins with Dumbledore, but symbols will symbolize the change in speakers. Also, chapters may signal the change.**

Chapter Four: Modern Day, A Hogwarts Account

The Great Ring has been with the school since its founding. Treated with great respect, it remains within a private room in the dungeons, guarded constantly by charms and the great Severus Snape. So when the day came that the Great Ring opened and travelers appeared, a great uproar occurred.

In my office, I knew nothing of the situation until Professor Snape ran into my door, knocking loudly, forgetting the password in his haste.

"Dumbledore! The Ring is open!" he yelled.

"Go! Bring whoever comes through directly to me!" I yelled also, and his retreating footsteps showed that he had followed my orders. ***

I returned to the dungeon to see four travelers: two men, a woman, and a strange alien with a symbol on his forehead. The travelers were holding Muggle weapons and speaking with American accents. The smallest of the two men was being tortured by magic. He was hanging upside down, and the students were chanting.

"Shall I remove his pants?" a voice sneered. It was Draco Malfoy. I burst into the close circle around him.

"SILENCE!" I screamed. Malfoy put his wand away, causing the traveler to fall. "Get back to your common rooms. Prefects help guide. Go!" I commanded.

"Well, that was a little more than I expected. Thanks for getting us out of that. I'm Jack O'Neill, and this is Dr. Daniel Jackson, Captain Samantha Carter, and Teal'c."

I began walking away. The man had sense enough to follow.

"So…where are we?" Jack O'Neill asked again. He had mumbled it before.

"My superior will inform you of your location, and what we shall do to you," I smirked.

"Not very friendly, eh?" he asked. I stopped.

"If I recall, you have invaded here, correct? Shall I detain you using my abilities? You're lucky you still have your weapons!"

"Fine, sorry," O'Neill whispered. I led them into Dumbledore's office.

"Sir, the travelers."

"Thank you, Professor Snape. You may sit. So, who are you all and why are you here?"

"I am Colonel Jack O'Neill, this is Captain Samantha Carter, Dr. Daniel Jackson, and Teal'c. We're explorers from Earth," O'Neill replied.

"This is Earth. Are you wizards?"

"No, Sir," O'Neill laughed. "We're Americans, well except for Teal'c here."

"I know nothing of other rings here on Earth. How many others are there?"

"I'm afraid that's classified information, but I did not know of another stargate."

"Stargate?" I scoffed.

"Severus, did you have a question?" Dumbledore asked.

"No sir."

"Colonel O'Neill, you used the term 'stargate'. I assume that it allows travelers into other areas of our galaxy?"

"You are correct," O'Neill replied. "Many, many other planets."

"And there is life on these other planets?" he asked. O'Neill nodded. "What about magical beings?"

"I'm not sure," O'Neill whispered.

"Sirs, if I may?" the woman asked. She stepped forward and they let her speak. "There very well may be wizards on other planets. I take that you hide your worlds very carefully and very well."

"We do, Madam, but…history, as it is currently written, holds gaps. If you, sons and daughters of the Ancients, have other relatives on other planets, then surely there are other witches and wizards."

"History? You mean, your people have had this gate for hundreds of years and no one knew?" O'Neill asked.

"Thousands! The Ancients are the only reason we exist here and now."

"If I may," the shorter man stepped forward. "You know of the past how? Are there records available for us to see?"

"No, Dr. Jackson. A great fire destroyed all of the original documents, but books written in response to those documents have told us what they could not," Dumbledore replied.

"If we could look at those…, maybe I could see."

"Wait," O'Neill interrupted. "I need to talk with my superiors. The MALP showed us an empty room, yet we are here on Earth in a castle that is a school? We need to figure out how this happened first."

"Jack, what do you mean? They may hold history that we've never seen before."

"Maybe so, Daniel, but I can't allow this. Dumbledore, you are the headmaster, correct?" O'Neill asked. He nodded. "But you also have a superior?"

"Of course, Colonel O'Neill. Everyone must be led."

"Can we contact our superiors while you contact yours?"

"Do you need the stargate?" Dumbledore asked.

"Please," O'Neill asked. And so we left together, reentering the room of the Great Ring. They quickly had an "outgoing wormhole" as the woman described it, and O'Neill consulted his superiors. While they talked, I plotted…

Chapter Five: The Clashing of the Worlds

The Americans quickly consulted us. They were willing to extend their knowledge to us if we would do the same. I quickly called for meetings and I provided a place for the travelers to stay. Professor Snape, however, expressed deep concern.

"Are you aware that this is the very thing that happened before? The Ancients promised partnership but they only provided pain!" Snape exclaimed.

"We must give them a chance, Professor. You must remember that we too failed the Ancients. That too can happen again, particularly with the attitude you show. They are our guests, Severus. We must treat them well."

Severus did not agree with our methods, and when their weapons fired in the night, his anger mounted.

An unfortunate ghost entered into the woman's chamber, and she in turn shot at him, but she was unable to scare him away. Also, she shot herself in the arm, causing her to require medical attention.

"Dr. Fraiser can help her," O'Neill whispered.

"We have medicine here that can heal her," I promised. After debating with O'Neill alone, she decided to trust us. Snape carefully monitored every moment.***

"General Hammond, I am aware, but…she insisted that it was best. I'm letting her decide," O'Neill said sternly.

"All right," I sighed. "But I want a briefing tomorrow morning as soon as possible. I still don't trust them!"

"They are allies, not enemies, Sir. This I believe."

"Then prove it."***

Our healing worked, and she was at our meetings in the morning. She helped describe the resources they could offer, and with the help from Dr. Jackson, she talked of how our great enemey, Lord Voldemort, could be defeated with their weapons. Many of my allies scoffed, particularly Professor Snape, but I lightly nodded with a smile.

Later in the meeting, we discussed security. Both sides would be protected by the other should anything happen, and both sides promised to keep the other's secrets. We then put everything in writing, signed the Ancients-Descendants Treaty, confirming that our two worlds were one. We then parted and they returned home to spread the news amongst their people. And we did the same. In such a short amount of time, we had combined two worlds, something that was thought to be impossible.

Chapter Six: Time Progresses

The wizards gave us knowledge of their history in later meetings. Daniel ate up every picture and every word. Carter enjoyed hearing about the liberation of their women, and Teal'c and I thoroughly enjoyed hearing of the many wars and battles that occurred throughout their history.

"I can't believe they went unnoticed," Daniel wrote in a report to General Hammond, who replied asking for us to see if they wanted to know more about us and our history. Dumbledore chuckled.

"We've been here too, you know. A witch helped create storms to knock ships of course to allow the discovery of your country. We tried to heal the natives ravaged by Eurupoean diseases. We helped the ships back to England to proclaim their independence, and we watched the rise and fall of the entire world in numerous battles in between. We are your greatest ally, your worst enemy, yet we remain hidden behind invisibility cloaks and charms. We know more than Daniel ever thought about the goings on of Ancient Greece and Rome. Did you know that wizards were involved with the fall of Babylon?"

"Sir, you lost me quite some time ago," I sighed. He chuckled.

"Now the…people of Teal'c, those are some interesting people, yes? I would enjoy knowing more about them, and the other races. Can everything be ready by Christmas?" he asked.

And so we made our first movie, or rather Daniel did. He recorded lectures concerning the Nox, Goa'uld, and the rise and fall of the many system lords. Seeing his hard work made all of us smile, and watching Dumbledore view the tapes gave us all a good laugh. He remained still and silent through all nine hours, commanding that it never stop. He applauded and invited us to feast. We remained, strengthening our bond.***

For Christmas, we held another large feast. We shared stories and everyone had a wonderful time. The only one without a smile was Professor Snape. Jack and his friends were sitting around him joking the entire time, but they shot him weary glances constantly. Once he left to go to the restroom, they spoke about him. I quietly tracked him down to consult him.

"Why are you not enjoying the night, Severus?" I asked.

"I have a bad feeling about them. They tell stories to portray themselves as heroes! Are they? They murdered the leaders of enslaved peoples and ran, not bothering to discover the terrors the chaos brought. They are far from heroes!" he spat in reply.

"You remember the movies from Dr. Jackson. The leaders were slaughtering the people at will. Our American friends did the people much good. They were free again. And our friends sent lower teams to get the worlds in order. They are their people's main line of defense, and ours, so they must be readily available. Do you understand this now?" I questioned. He glanced up cautiously from listening.

"They have done much good, yet they never speak of their mistakes."

"Would you, Severus?"

"No, but…"

"Enough. Enjoy the night, Severus, or do not return to the table," I said sternly. He bowed slightly.

"Good night then, Professor. Tell them a student required my time.

"I will not lie for you."

"But…fine," he whispered, following me to the table. He remained solemn and silent, but his eyes did flicker from speaker to speaker throughout the evening. Then we took to bed, saying goodbyes as they would leave early the next morning. Severus even shook their hands as they dialed home.

"See?" I asked. Severus nodded and went into his private quarters. I merely smiled.
