Hey guys, i decided to write a crossover for halo and sga, as i saw that there were no decent/current stories around the net that i could find. The only note that i want to add is that the events of this story take place just after the Last Stargate SG-1 episode, unending, which culminated in the collective suicide of the Asgard, and the inheritance the Tau'ri recieved from the little grey guys, effectively making them "the fifth race" so to speak.

So bear in mind that the timeframe is well before the finale of Atlantis, and the Daedalus has not yet recieved its refits, namely the Asgard system upgrades, (improved sensors, shields, beam transporters, hyperdrive, plasma beam arrays, ect)

As you can probably guess, i was NOT pleased in the least by the ending of the series, so i decided to come up with this a few years back, however this is the first time I've had to put the ideas in my head out into a physical printed format.

Act One

.//Reboot

USS Daedalus, en-route to Pegasus Galaxy - 'If these trips between earth and Atlantis are one thing, its uneventful,' thought Colonel Steven Caldwell. After being relieved by Colonel Sheppard, he was tucking into a rather large hoagie. It had been 3 days into the trip, and due to the fact that they were using the power of an ancient ZPM the Atlantis team had found earlier, the journey was significantly faster. If all went well, they should be entering the Pegasus galaxy in a little under a day. Just as he had taken his fourth bite into the delicious sandwich, he heard the last thing he wanted to hear over the ship's intercom system. "Colonel Caldwell, you need to see this, the scanners are picking up a weak distress beacon. We need you on the bridge sir." The voice of his communication officer was the last thing he wanted to hear at the moment, but nonetheless he pressed the small button on his standard issue communication earpiece, and replied; "Understood, I'm on my way."

As Caldwell entered the bridge, he looked around and saw that the members of John's team were already present. Ronan looking moody as usual, Tayla with a rather puzzled expression on her face, John with a nonchalant expression, and Rodney conversing excitedly with the communications officer. Noticing the ship's commander, John waved him over to the communication's console. "Take a look at this. I think we have a weak distress signal coming from a few hundred light years ahead of us," said John, with a look of excited interest on his face. Caldwell on the other hand was not as lax as Sheppard, and had a bit of a bad feeling about this signal. They were a few thousand light years from the very most edge of the Pegasus galaxy. Nothing should be out here except for, well, nothing.

Always preferring to err on the side of caution, he spoke to his navigator; "Drop us out of hyperspace at the very edge of our long range scanners, and prep the F-302 squadrons for scramble on the off chance of this being a wraith trap." "Aww, c'mon Caldwell. The Wraith don't lay elaborate traps like this. It isn't their style. They either jump you, or blast you with overwhelming numbers and firepower," drawled Sheppard. Secretly agreeing with the Atlantis team leader, but not enough to shake the bad feeling he had, he said nothing. "Sir, dropping out of hyperspace in three, two, one, mark. We have now reverted to real space."

"Activate long range scanners, and bring it onscreen," barked the Colonel. "Onscreen," said the communications officer. As the results of the scan was brought onscreen, the mood in the bridge tensed up considerably. The feed from the sensors was the last thing they expected to see. Instead of a lost trade ship, a abandoned beacon, or a wraith trap, they were greeted with the sight of the aft section of a wrecked warship, seemingly sheared in half by a horrendously powerful amount of energy. Feeling rather nervous, Caldwell wanted to see if there were any records in the SGC database that matched this wreck of a warship anywhere. He looked at McKay and was about to tell him to crosscheck the sensor data with the database, but before he opened his mouth, "Colonel, this doesn't match any type of ship operated by any known galactic faction we have come across before!" exclaimed the excited Canadian. The bad feeling Caldwell had was getting worse by the minute. "Rodney, bring the transmission onscreen," said John. "yes yes, I'm already on it. The coding is different, I just have to finish running it through a nifty little translation program I wrote myself, and, ah, done." With a smug little flourish, the scientist put the transmission on the main screen.

A tremor of surprise shook the bridge as the results were displayed. In a light blue hue was the symbol of a Phoenix rising up above what was unmistakably a depiction of earth. Underneath the symbol were the words UNSC Frigate Forward Unto Dawn. "Scan the wreck for survivors, I want to make sure that nobody is still trapped aboard that ship!" Exclaimed Caldwell. Seconds later, the communications officer blurted; "Sir! I am reading one life sign aboard, but its very weak. It seems to be consistent with cryogenic sleep!" "John, prep your team, we are going to beam you aboard. I want you to check it out, and see check out that life sign." said Caldwell. "Got it," replied Sheppard. "Tayla, Ronan, be ready in five. Same for you Rodney. Meet up in the armory for equipment, and make sure you have a EVA suit. Who knows if there is pressure on that hulk or not."

Cryostasis, UNSC Forward Unto Dawn - The A.I. Cortana flashed into existence on a holopad next to the only functioning cryobed in the remains of the frigate. Quickly she did a self diagnostic, and then checked the reserve power output of the auxiliary reactor. Satisfied that the reactor was functioning, she gazed upon the sleeping Spartan. She was debating waking him up after learning the results of her self diagnostic. The battle with Gravemind had taken its toll, as well as absorbing all the data from the first Forerunner Ringworld. "Wake me, when you need me," the Chief had told her, right before he climbed into the cryobed. She considered waking the Chief to tell him how she felt. A smart A.I. had a lifespan of about seven years, before they quite literally "thought themselves to death" how ironic, she reflected. Through everything she had faced with the Chief, her battles with Gravemind, the hordes of Covenant, and two harrowing escapes from exploding Forerunner artifacts, she was going to die from thinking. She wanted more than anything to let him know that she loved him. But every time she was poised to do it, here ethics subroutine overrode that course of action. Besides, she was an Artificial Intelligence, not a human. How was the Chief supposed to react? Resigning herself to the fact that she would most likely never go through with it, she quickly created a program to wake her in another month, to check on the status of the frozen super-soldier she cared so deeply for. Just as she was about to shut down, she noticed something.

It seemed that the Dawn was being scanned by something. Accessing what was left of the network of the crippled Frigate, she re-routed as much power as she dared to the passive sensors, making sure to keep an ample supply for herself and the Master Chief. As the passive sensors relayed the data to her, she decided to begin to thaw out the Chief. She overrode the programmed sleep cycle, and began an emergency quick thaw of the cryostasis. With a pop and a hiss, the lid of the cryobed opened..

John was running through the field. He was a boy still, and was filled with unexplainable elation. Suddenly he was back on his home planet, the name a distant memory. He was playing with the others, pushing them off of his hill. As the other children attempted to claim his throne, he stood tall, slightly stronger, smarter, faster and tougher then them all. Suddenly he heard his name called, and a man and woman were approaching him. "John is in trouble!" his friends chanted, and ran off. The woman, a pretty lady with glasses and a sharp look in her eyes kneeled down to John. She wanted to test him it seemed. All he had to do was guess what side a flipped coin would land on. He always had luck..

Suddenly he was back on Reach. He was focused, and he had a mission to complete. He had to bring all his comrades home with him, he wouldn't leave any behind. He and a few others scouted the position ahead of them, and saw a few marines guarding a Pelican dropship. He quickly assessed the size of the force guarding the transport and then mentally compiled a list of equipment he and his force had. Not much, as usual. Mendez always had a twist to his tests. He looked to the ground, and found a fist sized rock. He began to form an idea..

Racing forward, his mind flashed to the day he first met Cortana. She reminded him of Doctor Halsey. He was fitting his MJOLNIR armor for the first time, and was testing it. Doctor Halsey instructed him to insert the A.I. into the neural slot on the helmet, and was shocked at the sensation of another consciousness in his mind. During the test, the spunky A.I. showed her wit and intelligence, as well as her invaluable ability to save John's life. After all, there were two of them in here..

More quickly Johns dreaming mind went through his memories, picking out significant parts and highlighting them, the escape from Reach, the first contact with the Flood, the retrieval of Captain Keyes' neural unit, the escape from the Pillar of Autumn and the first ring, Sergeant Johnson, Miranda Keyes, the second Halo, Gravemind, meeting the Arbiter for the first time along with Gravemind, High Charity, the shame, guilt, and loss he felt when leaving Cortana behind..

Finally slowing, his subconscious slowly cycled through his time spent on the Ark, his partnership with the Arbiter, The death of Johnson and Miranda, the happiness he felt when he finally rescued Cortana from the clutches of the flood..

Cortana…

Suddenly he awoke, feeling the rough chafing feeling on his skin. The MJOLNIR armor system was designed for extreme periods of extended wear, but not in cryostasis, as such his skin was slightly raw and irritated. The Master Chief slowly rose up out of the Cryobed, and was faced with a worried looking Cortana. "Miss me already?" John teased her, causing a slight ripple in the codes flowing along her supple body, along with a momentary change in her light blue color to a slightly pinkish tinge. Ignoring the Chief's quip, the A.I. quickly stated the situation to the Spartan. "Sorry for interrupting your beauty sleep, but we have a unknown ship inbound. The vessel doesn't match any of the record in the Dawn's database, nor any of the files I downloaded when I hacked the ONI server." Without so much as a pause, the Chief got up, and started walking. "Where are you going?" asked Cortana. Without so much as a backward glance, the Spartan said in his dead, emotionless, combat voice, "To get a weapon."

Auxiliary reactor room, UNSC Forward Unto Dawn - A faint slithering sound was heard, and something was stirring in the darkness. A smell of rotten flesh permeated the air, and a faint wet slapping sound was heard, like a pair of rotted steaks being tossed on top of one another. A low rumbling growl was unleashed as the reactor room emergency lighting came online. Whatever was on the battered frigate, it didn't want to be seen for the moment.

Armory of USS Daedalus, orbiting UNSC Forward Unto Dawn - John was helping Tayla and Ronan climb into the cumbersome EVA suits. The former Runner and Tribeswoman were having trouble with the bulky suit, and they weren't too happy to be restricted to them. "I hate these things," grumbled a disgruntled Ronan. "If the Wraith decide to ambush us, we will be sitting ducks. You can hardly even walk in these things." The danger of a possible Wraith ambush lost upon the Canadian, McKay was rambling on about the possible salvageable technologies onboard the derelict vessel. He had done a rudimentary analysis of the sheared section of the Forward Unto Dawn, and found that not only was the alloy incredibly strong, even stronger than the naquadah composite alloy that served as the armor for the 304 Deepspace Carriers. So as he pointed out on the bridge, the ship was actually tougher than the Daedalus, which elicited some rather shocked looks from the crew. Based on his initial findings, the amount of energy required to simply shear this ship in half must have been astronomical. Already in his EVA suit, Rodney picked up his ever present tablet computer, and double checked his calculations. Sheppard, finally managing to get the other two in their pressurized attire, picked up his P90 and some spare ammunition, just in case. Tayla also took a P90, as well as a Wraith stun pistol. Ronan was armed with his trademark blaster, and Rodney had his 9MM Glock, inside of his suit.

"Rodney, why is your gun inside your suit?" asked a thoroughly irritated Sheppard. "What good is it going to do you if you have to fight in a no pressure environment?!" a irritated Doctor McKay glared at the colonel and snapped "About as much good as yours is going to do you Sheppard. For you information, if it comes down to a fight in a no pressure environment, which I seriously doubt will happen, our weapons may as well be rocks. There is no oxygen in space, nor in zero pressure for that matter. Therefore the combustion reaction required to propel the bullet cannot take place. So in actuality, you are no better than me in this situation." Sheppard, thoroughly annoyed with being scolded by the scientist, unconsciously pulled his weapon closer to his chest and replied; "well, I think ill take it, just in case." Rolling her eyes, Tayla activated her earpiece and said "Tayla to Caldwell, we are ready for transport. Beam us over when you ready." The team's earpieces crackled to life and Caldwell's voice said "I hear you Tayla, prep for insertion in five. Good luck to you, we will be standing by to beam you out at a moments notice. Caldwell out." Ronan mentally steeled himself when he heard that. Despite all the times he had been beamed in and out of the ship, it was still an unsettling experience for him. Closing his eyes, he heard the activation of the Asgard technology, and the unsettling feeling of his body being disassembled to the last atom, then instantly reassembled. When he finally realized he was whole, the tall, dreadlock sporting man opened his eyes, and was greeted with a shocking view.

Armory of UNSC Frigate Forward Unto Dawn - The Master Chief looked around the expansive room he now stood in. technically it was a small armory by the standards of the UNSC, but as standards go, the UNSC was not exactly typical. Where he stood now was more of a gymnasium than a room. The Armory was huge, with rows of weapons, crates of ammunition, and strings of belts attached with grenades. Looking around, the he picked up his weapon of choice, the weapon that had seen him through hordes of covenant and swarms of flood, through two ring worlds, the Ark, his second run through High Charity, and countless other situations, the MA5C. The sturdy assault rifle was a good choice in almost any situation, with a near perfect balance of range, accuracy, clip size and stopping power. It was the Chief's personal opinion that he would not be alive today had it not been for this weapon.

Setting the gun aside for the moment, he walked over and picked up a strange looking object, that seemed to be nothing more that a handle. The opposite sides were emitting a faint glow, but it was something that would be easily looked over had someone not know what it was. He picked up the object, and squeezed the handle. With a hiss and a flash of bluish green light, a crackling twin pronged sword appeared, seemingly made of energized plasma. Giving it another slight squeeze, the blade disappeared. With a satisfying clink of metal on metal, the John placed the Type 1 Energy Weapon on his left magnetized thigh plate, and moved on to the sidearm section of the armory. Looking around, he saw something that significantly brightened his mood. Walking over he picked up a M6D Magnum. This weapon was a pistol, but it had a significant punch to it. The relatively oversized pistol could kill an elite from roughly a hundred meters with a few well placed shots, and devastated unshielded infantry due to the semi-armor piercing explosive rounds it fired. If that want enough, the scope feature that liked with his HUD in his suit only added to the deadliness of the weapon. Not many had survived the war, and by the time he had returned to Earth from the first Halo, the pistol was a rarity indeed.

Placing the pistol on his right magnetized thigh plate, the Spartan spotted something that caused his gut to wrench. Leaning up against the wall, next to a few recharge packs, was a Model 6 Grindell/Galilean Non-Linear Rifle, dubbed the Spartan Laser by the Marines of the UNSC. Few marines were strong enough to lug the heavy weapon around, and fewer still were able to use it for extended periods due to its massive size. But it wasn't the fact that it was just a weapon that caused the Spartan to react, it was the man who gave it to him. The man who, to his death, fought to protect humanity, and was one of the few non-Spartans John deemed an equal and worthy of his respect. As he picked it up and placed the weapon on his magnetized back plate, his memory flashed back to the last moments of Sergeant Avery Johnson.

The Master Chief and the Arbiter were just outside of the Control room of the partially completed Halo, the sword of the long dead Forerunners. They were standing back to back, the Chief wielding a battle rifle and the Arbiter his energy sword. The Chief fired a three round burst, the high velocity rifle rounds tearing through the chest of the Flood combat form. Whirling, he noticed a pair of Infected Jiralhanae storming towards him, their ferocity and strength only amplified by the Flood infection forms controlling their corpses like morbid puppeteers. One of the charging juggernauts was wielding a Type 2 Energy weapon, otherwise known as a Gravity Hammer. Firing 6 rounds into the chests of both forms, the Spartan dropped the charging pair, black infected blood and clear oozing ichor pouring from both bodies. Silently thanking Doctor Halsey for the millionth time for installing filters in the suits system, as well as a temporary pressurized air supply, he picked up the giant weapon, using its powerful strikes to decimate the legions of Flood hell-bent on assimilating him and his Sangheili comrade. As he swung the fearsome weapon, the flood beneath its head splattered in a morbid shower of blood, guts, ichor, and gas, as the host body was utterly decimated and the infection form controlling it popped with a sickening sound.

"Wort, Wort, Wort!!" startled by the traditional Sangheili battle call, the Chief looked over his shoulder to see his friend being overwhelmed by combat forms. The Elite's shields were down, and rivulets of purplish blood rand down from several bullet wounds inflicted from the SMG firing combat forms. Quickly acting, John detached a Bubble Shield from his belt and threw it at the Arbiter, its golden-tinged field providing a temporary respite for the besieged warrior. Without skipping a beat, the genetically enhanced super-soldier threw a fragmentation grenade at the infected humans spraying a wall of lead at the alien. The throw was perfect, the grenade hit the ground and bounced up, the delay fuse activating when it hit the ground and detonating at chest height, shredding the defiled bodies of once proud UNSC Marines. The Arbiter engaged his second plasma blade, and charged the mass of infected Flood, slicing through the abominations like they were nothing more than paper, a sickening hiss as each strike sliced off limbs, cut bodies in half and decapitated scores of the creatures. Finally, the Monitor, 343 Guilty Spark, managed to get the doors open. As the pair retreated into the opening, they were faced by a pair of infected Lek'golo. Just as the two warriors were beginning to feel the fear of death, a blood red beam lanced down from a cliff a few hundred meters behind their position. The beam, utterly destroyed the infected Lek'golo, smoldering pieces of flesh and fragments of armor were all that remained of the giants. Suddenly the comm crackled to life "Go you two, get to the control room! I've got you covered." Silently thanking the cigar loving Sergeant for the timely support, the Chief and the Arbiter charged into the control room. Running up to the holographic control panel, the Chief touched a glowing panel, and felt the presence of Cortana leave his mind.

Just as Cortana was about to activate the ring for a remote firing sequence, 343 Guilty Spark turned on the chief, the A.I. running rampant, immobilizing the Arbiter and firing on the Chief. Just as his shields finally failed, another crimson lance of energy struck the floating orb. "How dare you?!" screeched the monitor, "As a Reclaimer it is your duty to preserve the integrity of this installation! Activating it will result in its destruction!" Johnson, looking unimpressed, fired another blast of the powerful weapon, replying "You know, you talk too much for a light bulb." Just as the Spartan's shields were fully recharged, Guilty Spark unleashed a torrent of energy into the seemingly indestructible marine. Rushing to his side, the Sergeant handed him the powerful weapon, and with his last words, ordered him to protect Cortana. With anger coursing through his veins at the death of his friend, the 7 foot tall armored powerhouse hefted the Spartan Laser, aimed at the Monitor and unleashed a torrent of energy, avenging the death of his comrade.

Shaking himself of his reverie, the Spartan then gathered clips for his Magnum and his assault rifle, and an ample supply of recharging power packs for his Spartan Laser. Satisfied with the amount of ammo he had gathered, he put the clips and packs into his pop out ammo holsters near his magnetic thigh plates, and proceeded to gather grenades. As he attached two fragmentation grenades, a pair of spike grenades, a couple of plasma grenades, as well as some incendiary grenades for good measure, he walked back to where he set aside his MA5C, picked it up, and walked back to the Cryobay where Cortana was waiting for him, an impatient expression on her exotic face.

"Your not assaulting High Charity you know, don't you think your going a bit overboard?" asked the A.I. with one eyebrow raised, noting all the firepower the Spartan had equipped himself with. Pretending not to hear her query, John asked; "So what's the situation?" Looking like she was trying to hold back a smile, Cortana replied "The Dawn's sensors have determined that the unknown vessel is orbiting us, and I recently picked up a strange energy fluctuation from the vehicle bay. After the anomaly had dispersed, I picked up four life signs, though the Dawns sensors are too damaged in that region to determine the species. I have no idea what they are, human, covenant, or flood. There is simply no way to tell. I have activated emergency lighting throughout the ship, and pressurized the sections where the hull integrity is not compromised." Acknowledging the her with a slight nod, the Spartan asked "Is that all?" Looking irritated, the A.I. snapped, "Yes, seeing as I don't have a physical body, I cant exactly repair the ship's systems myself." Ignoring the outburst, the Spartan reached down and removed the tiny chip that housed his A.I. companion from the holopad. Carefully he inserted the chip into his neural interface, and the familiar feeling of ice cold mercury flooding his brain returned, indicating the return of Cortana to his mind. 'I'm picking up patchy transmissions from the unknown vessel orbiting us and the team in the vehicle bay, however they are too garbled to make heads or tails of.' 'Understood' John though, knowing that Cortana could hear him. With that thought, he proceeded to make his way to the vehicle bay, traveling surprisingly stealthily despite being clad in such heavy armor.

UNSC Forward Unto Dawn, Aft Vehicle Bay - Sheppard looked up in awe and amazement at the sight he now beheld. Blinking multiple times to be sure that what he was seeing was correct, his jaw dropped slightly as he understood where he was. Looking around, he noted he was in the bottom level of a cavernous Vehicle bay. It was roughly half a kilometer long, a quarter of a kilometer wide and had six levels two it, and from what he could see, was relatively full still. On the bottom level, to his left were rows of mean looking scout vehicles, with four wheels, wicked looking suspensions, and either vicious looking cannon-like turrets on the back or a gigantic chain gun. Looking to his right, he saw rows upon rows of huge tanks, most with plasma scars, but impressive nonetheless. Silently wondering who these mysterious people were fighting, and why just one ship sported almost an entire battalion of armor on just one level, the battle hardened colonel, and felt a pang of unease at the sight. The two levels above the bottom deck were filled with mean looking ships, which he assumed were dropships or transports by their size. The levels above that was filled with various aircraft, small and large VTOL units, huge ships that john guessed were fighters, and what looked like huge, flying tanks.

Finally managing to take his eyes off the sight, Sheppard looked around at his team, judging by the expressions on their faces that they were equally shocked. Even McKay was at a loss for words, something that rarely happened with the narcissistic scientist. Suddenly John began to get a very bad feeling about this wreck. Ronan suddenly spoke up, voicing and validating his own fears; "Whoever had the resources to field an operation like this, and needed this much firepower to combat their enemy, shouldn't have left their ship abandoned like this. They would have been more than capable of mounting a salvage and rescue operation. And where is the rest of the crew?! I don't like this much. I say we go, find out whatever it is that may be alive on this ship, find out what happened, and get the hell off." McKay however, was not satisfied with simply leaving that quickly. Excitedly he spoke up in his aggravatingly commanding tone, "We can't just leave! I'm getting some insane power readings in here, and judging from the lighting, it is only running on auxiliary power! Any civilization that has the capability of producing weapons on this scale must be incredibly advanced! We have to try to see if we can salvage any technology, and analyze their power system." Tayla, who had just regained her composure, glared at the excited Canadian. "We are not going to steal from this vessel, the items don't belong to us!" spat Tayla. "Yes, yes, stealing is bad we all know that. Basic human morals and such. Look around however. Do you see anyone onboard? I sure don't, and since nobody is home, nobody is going to use this stuff, and I don't think we should let it go to waste." retorted the miffed scientist.

Sheppard, wanting to quell the argument, ended the debate. "Tayla, I understand where your coming from, but I agree with Rodney on this one for once. Its obvious this ship has been abandoned, so we might as well investigate and see what we can use." Warily looking about, he decided to split the team up to cover more ground quickly. "Ronan, your with Tayla, Rodney, you with me. Lets split up and see what we can uncover. Maintain constant radio contact, and don't get lost. This ghost ship gives me the creeps. Should anything happen, we all meet back here and radio for extraction. Now that that's out of the way, lets get moving. I don't want to be here any longer than necessary, Rodney." The disgruntled Colonel said with a venomous look at McKay. The man had saved their skins many times over, but always managed to get the team, himself or the mission in trouble due to his inquisitive nature. Activating the flashlight on the stock of his P90, Sheppard and Rodney began trekking through the dimly lit passages honeycombing the remains of the Forward Unto Dawn…

To be continued.
