AN: Yes, I know I have two other fics that need updating :P

But this idea bit me hard, and I just had to write it. This is my take on the (somewhat cliche by now) 'Odyssey gets thrown into different universe while running from Ori' idea. In this case, it is Halo. I did my best to make this interesting, and (in later chapters) keep things balanced. I hope you all enjoy the work I put into this, and leave a review on the way out! :D

USS Odyssey

May 13th 2007 (outside time-dilation field, 2057 inside)

A deep silence echoed through the halls of the USS Odyssey. Instead of the normal bustle of a ship and its crew, nothing at all made a noise. There was a small humming noise from the machinery, but that was the extent of things. And even that was quieter than it should have been, as the vessel was slowly shutting down as it aged, and its systems ran out of power.

If one walked through the halls, they would see small signs of rust, and other hints of the vessels age. If they continued further, they would start to hear soft voices coming from a side room. Inside the room, were the only people aboard the Odyssey. Looking at the group, it was readily apparent that the years had not been kind to them either.

There were two women sitting at the table, both with long graying hair. One of them was looking at a man standing next to the window, his hair somewhat long too. The other was eating some food across from another old man, with hair nearly as long as her own. The only person in the room who was not showing his age was a tall, well muscled man with only a single streak of gray hair.

The group appeared to be in the middle of an argument, though why wasn't readily apparent.

"One of us has to stay like this? No offense, but I could do without the arthritis," the man next to the window said.

"It has to be that way Cam. One of us needs to remember what happened, or we'll be in the same situation…the time reversal will erase any memories of these years," one of the women said.

"Well it certainly can't be you then Sam," the man, Cam Mitchell, said.

"I agree with Cam," the other old man said, "We need your mind too much to let you stay this age Sam."

Sam Carter turned to the man, "Daniel, the same goes for you. You know more about the Ancients and the Asgard than anyone."

"Well I certainly won't do it," the other woman said, "I want my old body back thank you. This one is so old and ugly."

Daniel Jackson was the one to turn his head this time, "Really Vala?"

Vala Mal Doran shrugged, "Hey, I'm just being honest. Don't tell me you like this either Daniel."

The argument the group was involved in was which of them was going to stay the age they currently were. The reason why one of them had to do so was simple…all one had to do was look out a window, and they could see a golden bolt of energy seemingly frozen in time. The Odyssey was sitting in a Time-Dilation field, with an attacking Ori Mothership right outside of it. The reason that this affected one of them staying old was also simple…the current plan was to use the energy of the beam to reverse time inside the field. The problem was that it would also erase any memories of the fifty years that the crew had spent in the field.

Thus, one of them would be shielded and have a crystal to shut down the Asgard Legacy, which would stop the Ori from tracing them. Of course, none of them particularly wanted to remain their current age, but all in the room knew it was needed. The last person in the room had been listening silently for that very reason. But now, he stood up and addressed the group.

"I shall do it. As a Jaffa, I age far slower than a human," the man said.

"Oh come on Teal'c…you've lost just as much as we have. You're what…150 now?" Cam said, waving a hand at Teal'c.

The Jaffa warrior just raised an eyebrow, "I am the only choice Colonel Mitchell."

Before Cam could argue, Sam started to support her friend, "I have to agree with Teal'c on this one. The rest of us are at our limits. But still…are you sure about this Teal'c?"

This time Teal'c just nodded, which was all Sam needed. She stood up and set out for the control room for the Asgard Legacy. They had wasted enough time after all…why bother waiting any longer than was needed? Teal'c followed her, while Cam continued to stare out the window. Quickly realizing what was going to happen soon, Daniel and Vala left to the formers quarters. This would be the last time they could stay together like this, and they were not going to waste it.

While they were going to the quarters, Sam and Teal'c had reached the Core Room. In front of them was a large Asgard device, identified by its smooth design and almost translucent white coloration. It had a gentle hum, indicating that it was still providing what power it had left to maintaining the field.

Sam walked up to the core, and moved one of the crystals on top. With that done, a panel opened in the middle of the device, holding several more crystals. Sam removed one of the panels, and handed it to a silent Teal'c.

"This is the program that will disconnect the core. You have to get this to me before I activate the time dilation field. It will be for nothing if you don't do that," the scientist said seriously.

Teal'c nodded again, "I will Colonel Carter."

Sam smiled lightly, "I know you will Teal'c. I'll miss this time I spent with you, Cam, Daniel…I'll even miss the time with Vala."

Teal'c remained silent, but his presence was enough for Sam. She let the smile trail off, and gave Teal'c instructions on where he needed to be for the shield to work. As the Jaffa walked off, Sam started to manipulate the console. The moment that her friend reached his destination, she activated a shield around his body, and dropped the dilation field.

The previously stationary Ori beam shot forward, and hit the shieldless Odyssey right in its long neck. The beam tore clean through, setting off a cascade of explosions, and destroying the ship piece by piece. In the center of this stood Teal'c, enclosed in his shield as fire grew around him. But as the stoic Jaffa watched, the fire receded, and the Odyssey 'rebuilt' itself.

But Teal'c neither knew, nor expected, just what that beam had done…

"Whatever you're going to do Sam do it quick!" Cam shouted from the bridge, as sparks flew around his head.

"Almost there…" Sam muttered under her breath, but right as she was about to start the dilation field, a hand stopped her.

Looking up, Sam saw Teal'c…but he looked different. There was a streak of gray in his hair, where before it had been pure black. Teal'c shook his head, and handed Sam a crystal. Trusting her friend, Sam inserted the crystal where he showed her to. As soon as the crystal was inserted, the Core shut down.

"Cam! The Core is down, we can jump to hyperspace now!" Sam called through the radio.

But they didn't feel the characteristic jump, and the Odyssey seemed to have not moved at all. This obviously confused both Sam and Teal'c, as they should have jumped, or the Ori beam would have destroyed them.

"Cam?" Sam asked.

Silence reigned, before Cam's voice came over the radio, "The Ori ship…it isn't there anymore. It just vanished into thin air."

Sam and Teal'c looked at each other, both showing confused looks (or as confused as Teal'c ever showed).

Sam reached for her radio again, "Can you confirm that Cam? It just vanished? No hyperspace window?"

"Yeah, no hyperspace window or anything. It was there one second, and gone the next. Any idea what happened Sam?" the Colonel asked.

Sam really looked confused now. Unless the Ori suddenly had cloaks, they shouldn't have just vanished like that. The only other explanation that made sense was the Ancients finally getting involved, but that was about as likely as a Goa'uld showing up to help.

Sam turned to Teal'c before gesturing for the door, "We need to get up to the bridge Teal'c."

The Jaffa nodded, "Indeed."

The pair left the Core, and started to ascend to the bridge. The ship was quiet, as no one else was wandering the halls. They had dropped off the crew before fleeing the Ori, and it showed. The only other people aboard the Odyssey were already on the bridge.

As Sam and Teal'c walked into said room, they saw Cam, Daniel, Landry, and Vala looking out the expansive window. All of them were looking towards where the Ori ship had previously been. But instead of the distinctive white warship, there was just a twinkling star field. Not even any debris to indicate the vessel had been destroyed.

Daniel was the first to notice Sam and Teal'c, and turned around. He naturally noticed Teal'c's new gray streak, and commented on it.

"Teal'c…what happened to your hair?" the former Archeologist asked.

Teal'c raised an eyebrow, as the rest of the 'crew' turned around.

Vala was the second one to notice, "Yeah Muscles…dyeing your hair?"

The eyebrow rose higher, before Landry cut off the conversation, "As interesting as this is, do you have any idea how this Ori ship vanished?"

Sam looked over the sensor readings while Vala continued to examine Teal'c. Nothing that she saw made sense however…by all rights that Ori ship should still have been out there. The Odyssey had not moved in the slightest, and all the stars looked the sa…wait…

"Sir…you need to see this," Sam said, bringing up an image of the star charts.

Landry walked up and examined the chart. He didn't see anything different though.

"What am I looking at Colonel?" the General asked.

Sam brought up another star chart. And when one looked closely, they could see that in the first chart the stars were in a slightly different position.

"The first chart is the star chart from our current position. The second one is what it should be," Sam explained.

"What it 'should' be?" Daniel asked, almost dreading the answer.

Sam nodded curtly, "Yes…according to the sensors, the stars have accumulated about 500 years of stellar drift. Whatever happened…it shot us forward that far."

One could have heard a pin drop on the bridge of the cruiser. This was easily the only way the situation they had been in could have gotten worse. They had gone from being on their way back to Earth, hounded by the Ori, to being sling-shotted several hundred years into the future.

This was an ominous situation…was Earth still the same? Or had the Ori managed to conquer the planet? Would they return to find a slave world? Or a destroyed wasteland?

Questions like these were running through the heads of every member of the crew. The most prevalent question by far however, was if they could find a way back home. None of them wanted to believe they were stranded, with good reason.

"Sam…can you get us back?" Daniel asked.

Sam continued to study the sensor logs, before slumping her shoulders. She slowly turned around, and just as slowly shook her head.

"I can't. I honestly don't even know what happened to get us here…" the Colonel said sadly.

Teal'c stepped forward, "I can explain what I know Colonel Carter."

And with that, he gave the group on the bridge a short tale of the 50 years he had spent on the Odyssey. The Jaffa cut out most of the details, and focused on Sam's plan to save them from the Ori. When he detailed the plan to use the power in the Ori Beam to power the Core, Sam sighed and interrupted her old friend.

"That must be what did it then. I can't believe what I was thinking…the power in that beam couldn't be controlled. It is a miracle this is all that happened to us," Sam said with a shake of her head.

"Hey now…don't go blaming yourself Sam," Cam said with a shake of his own head, "We're still alive aren't we?"

Of course, that was only technically true. While the group was indeed still alive where they were, they were 'dead' back home. And without the technology aboard the Odyssey…Earth most likely fell. Even the Antarctic Weapons Platform couldn't hold back the Ori. And that was putting a damper on the mood of all aboard the cruiser.

But they couldn't let it stop them. So Landry stepped back up to the Captain's chair, and started to give out orders.

"We can't stay here. What is the nearest planet with a Stargate Colonel?" the older man asked.

"P3X-579 sir," Sam answered immediately.

Landry nodded, "Is the Hyperdrive functional?"

Sam nodded herself, "Yes sir."

"Then get us underway Colonel Mitchell," Landry replied, turning to Cam.

The Colonel nodded, and sat in the vacant helm position. He activated the sublight engines first, sending the cruiser on a new course. Then he activated the Asgard Hyperdrive, sending the ship launching forward at speeds that no other race could hope to match. It would only take them a matter of minutes to reach P3X-579, though none of them knew exactly what they would find…

Sigma Octanus System

UNSC Iroquois

July 17th, 2552

Meanwhile, a larger ship coasted through space. This vessel was also human in design, but it looked nothing like the Odyssey. This vessel was coated in heavy armor, and an even more angular/utilitarian design. As it floated through space, its four engines propelled it forward at a leisurely pace.

The ship was the UNSC Iroquois, a destroyer that had only recently been assigned to this system. This vessel was typical of its class, only being identified by the large red 'warstripes' painted along its side hull. At the moment it was on an extended patrol around the Sigma Octanus system, keeping an eye out for any Covenant incursions.

On the bridge of the vessel, Commander Jacob Keyes was idly tapping his old pipe against the arm of his command seat. It was a habit of his, along with chewing on the tip. He had only recently (a couple of months before hand) taken command of the Iroquois, and this was a fairly routine mission.

Nothing in sight, and no sign of the Covenant. Let's hope it stays that way, Keyes thought, looking out at space.

But while he was looking, an alarm started to blare throughout the bridge the destroyer. Keyes quickly stood up, as one of his crew called out what was causing the alarm.

"Unknown spatial disturbance ahead! Not consistent with Covenant or UNSC Splipspace portals!" the officer called out.

"Weapons! Charge the MAC and ready the Archer Pods," Keyes belted out, as it was better to be prepared than caught flat-footed.

"MAC is charging, 10 percent and climbing," Aki Hikowa called out, "Archer pods warmed and ready for firing."

Keyes nodded in approval…he had been worried about his weapons officer, and she was proving to be competent. Now it was a wait to see exactly what was rapidly approaching Sigma Octanus. And it wasn't a long wait, as a massive purple…rip…in space appeared in front of the Iroquois. It was similar to a Splipspace vortex, but different at the same time.

As the crew of the destroyer looked on, a small ship shot out of the 'rip' at an insane velocity. The ship then quickly slowed down, before coasting to a halt in front of the Iroquois.Looking at the ship, it bore some resemblance to UNSC ships. But it was more streamlined, and was only slightly bigger than a Corvette.

What was odd was the fact that the vessel couldn't be quickly classified. At first, one would think it was a Corvette, due to the size and lack of a MAC gun. But the pods on the side appeared to be for fighters, which no Corvette could carry. And the power readings were off the charts, more equivalent to the likes of a Cruiser than a Crovette.

The ship seemed content to just float in space though. It made no move to attack the Iroquois or move past the Destroyer. Keyes was somewhat confused by this. If the ship in front of him was some experimental UNSC design (considering it looked like it could be), it would have communicated with him by now. And if it were, God forbid, a Covenant trick, they would have fired on the Iroquois. The whole situation was maddeningly confusing.

"Has the vessel made any attempts at communication?" Keyes asked.

Lieutenant Hall shook her head, "Nothing sir."

Keyes nodded slightly, "Very well. Send out a query of who they are and their purpose here. It may be an experimental ship of ONI's."

Hall nodded and started to send out the ordered message. At first, the other ship remained silent, before a voice came over the radio.

"This is General Hank Landry in command of the USS Odyssey of Earth. Who am I speaking to?" an older male voice echoed over the radio.

In an eerie repeat of the earlier situation aboard the Odyssey one could hear a pin drop on the bridge of the UNSC vessel. All of the crew looked at each other, forgetting military protocol in a joint moment of shock. It seemed like this was indeed a human warship…but there was no vessel in the UNSC Navy known as 'Odyssey'. And the 'USS' prefix hadn't been used in centuries.

Unsurprisingly, Keyes was the first to recover. He walked up to Hall's station and started to talk to the other ship, "This is the UNSC Iroquois, Command Keyes commanding. You will understand if I'm doubtful of your identification. The UNSC is the military arm of Earth and her Colonies, and I have never heard of a Corvette named Odyssey."

There was silence over the comms again, before Landry came back, "Earth and her Colonies? UNSC?"

"Yes, and I can only assume that you are Insurrectionists if you are not Covenant or UNSC," Keyes said, using the only option that really made sense, "If so, I have to ask you to halt any forward movement and power down any weapons."

The Odyssey still hadn't moved, but that didn't mean much. The scans from the Iroquois were being reflected somehow, and they couldn't get a good reading on its weapons.

"We are not what you call 'Insurrectionists'. This will be hard to believe, but our vessel is not from this reality, or even this time period," Landry said, to shocked looks, "Have you ever heard of the alternate reality theories? It is possible, though difficult, to travel between them. We had a malfunction in our power systems, and it somehow sent us here."

Keyes frowned at that explanation. After all, it went against everything he had ever learned in his years serving the UNSC. There had been ideas that it was possible to use Slipspace to break into another reality, but it was just that…an idea. There was no proof that an alternate reality existed. And time travel was just as hard to believe.

"That is hard to believe Odyssey. All of the UNSC's experiments indicate that it should not be possible to break the dimensional barrier, even assuming there truly are alternate realities," Keyes replied, "The same goes for time travel."

"Perhaps we can send over our sensor log…" Landry started, before an alarm could be heard in the background, "Our long rage sensors just picked up something. We can't tell what it is though."

Keyes turned to his own crew, where one of them was holding up a report. The report was from a Slipspace monitoring station, which had picked up a large mass approaching Sigma Octanus. At first, it looked like a rogue asteroid, but that was horribly rare. Keyes remembered reading a report by one of the 'washed-out' Spartans, that might explain this. Large masses in Slipspace distorted space more than in normal space. And if one flew in close enough formation…like the Covenant could do…

Keyes' eyes widened slightly. If he was calculating this right, the mass was four Covenant Frigates. More than a match for a single UNSC Destroyer like the Iroquois. But he still had to do something to stop the intruders.

"Where is the anomaly exiting Slipspace?" the Commander asked quickly.

An outline appeared on the tactical board a few dozen kilometers behind the Odyssey, "That is our best guess sir."

Keyes nodded and turned to his helmsman, "Get us there Lieutenant!"

The man looked distinctly unhappy, but he still fired the engines and started to move the Iroquois to its destination. The Odyssey moved out of the way, not sure exactly what was going on. But they got their answer as a large purple hole opened in space, vomiting out not four frigates…but two frigates, a destroyer, and a large carrier…
