A/N; so this is another story, this one however is more of an experiment o my part to try and help with character development as people say i need to i improve with it, because of this don't expect this to be well written, i'll try and keep it good enough to read but as i said its mainly to improve character development, so read review and tell me where to improve. thanks

His squad had been massacred by the Forerunner defence AI, his first chance to lead a team had ended in failure, he had managed to get past his post-traumatic vocal disarticulation, and managed to get promoted and was trusted to lead his team and keep them safe, he failed.

His mission was to hold some Forerunner device until they could figure out what it did, they had a few weapon crates filled with ammo and guns, his team of ODSTs had a standard load out, and they were some of humanities finest soldiers, they weren't SPARTANS but they were damn good. The Infinity had crashed a few days ago and they had found this place not long after, the room with the device was large and relatively empty, the device itself was in the centre of the room a single console stood next to it, the device was flat on the floor, it was a weird ring thing that stood six inches tall and a foot thick and about twelve metres in circumference, it was rather uninteresting, it didn't even look like it did anything but according to the scientists it did.

When the Forerunner AIs attacked they had just activated the device, the centre of the ring looked like it had a slip-space rupture inside of it. The scientists were the first to be killed by the AIs; they didn't even see what killed them before they were turned to the ash, he had ordered his squad to open fire on the crawling AIs, Private Hall had been overwhelmed by the crawlers. The rest of the squad took cover behind portable cover, the massive pieces of metal provided effective cover against the powerful hard light weapons. When the larger and more powerful knights appeared, they started swarming the five remaining ODSTs; Lance Corporal Jameson took a light rifle shot to the chest as she leant out of cover to shoot, she started screaming as the shot burned through her armour, one of the Promethean knights walked up to her, another knight had gotten behind Lance Corporal Scott and Corporal Evans, it sliced at Scott with its hard light blade, as Scott was turning to ash Evans was shot point blank with the rifle on it arm. James looked back at Jameson and saw the knight was stood over her, ready to impale the ODST; James switched his battle rifle to automatic, stood up and charged the knight, firing all the way, the knight looked up at the charging soldier, the shields failed on the knight and charged him back, the two ran at each other James ran out ammo but he didn't stop, intending to use the empty gun as a club, the larger AI slammed into him, he was sent flying into the weapons crate which had been blasted close to the edge of the ring by a stray grenade, when he knocked into it, the crate fell into the blue-black centre of the ring. James Darrow landed on the edge if the ring he looked up to see Jameson be finished off by one of the other AIs. The one he had charged walked up to him and lifted him up to its face, its helmet opened down the middle revealing what looked like a human skull as it screamed into his face, he slowly grabbed the knife in his boot, as the AI finished it scream he plunged the knife into it neck, the sudden movement caught it off guard so it lost its balance, they both fell into the centre of the ring and everything went black.

Colorado- Cheyenne mountain complex, SGC- October 15th 2000

Chief Master Sargent Walter Harriman was on duty watching over the stargate, so far his shift had been uneventful, mainly because Sg-1 was currently on base and there weren't any teams due back for a few more hours. After checking all the systems again he decided to play solitaire, it was the only game on the computer plus the General wouldn't mind seeing as it was getting late and there was nothing to do. After some time he heard something and looked up at the stargate, he noticed he was the only one in the control room, he looked back at the 'gate and saw small blue sparks jump from the centre of the gate, he was about to sound the alarm when a blue-black thing appeared in front of the gate, it was bigger than the gate and blocked it from sight, he smacked the alarm and soon enough marines and SFs were flooding the gate room, and General Hammond came down the stairs from the briefing room,

"What's going on Sargent? And what in God's name is that thing?" he asked the second he saw the portal thing.

"I don't know sir; it just appeared out of nowhere." Walter replied, 'why does this always happen on my shift' he thought.

Bits of dust seemed to fly out of the portal; the guards had their weapons trained on the anomaly, Major Carter and Colonel O'Neill had just walked into the control room when a large crate flew out of the portal and smashed into the wall just below the control room, the SFs had to dive out of the way of the projectile crate.

"Well there's something you don't see every day," Jack quipped, always making a joke out of things,

Just as Sam was about to reply two people flew out and landed with a heavy thud on the floor, the SFs all trained their weapons on the people, Jack and Sam both ran into the gate room and took a weapon off of one of the SFs, Jack went to the people and saw that one was definitely not a person, parts of it seemed to float and weren't connected to it, there was a knife stuck in its neck, the person below the thing however seemed human, but it was covered head to toe in black and grey armour, the thing was grey and orange stood up, it looked around the gate room and looked at Jack, it leant forward and let out a scream as its helmet opened, Jack jumped back in surprise at the human skull in the helmet, it stood to its full height, at little over ten foot it towered over everyone in the gate room, the SFs opened fire as it raised it gun, which was also its hand, the thing fell under the combined fire, but not before firing a shot which hit one of the SFs, the man screamed as he turned to ash, the thing finally died and also started to turn to dust, it dropped it gun and the knife in its neck next to where it had died.

Jack walked up to the other figure, and from the looks of it he had also been the one to stab the robot thing that had just attacked, the figure on the ground had been in a fight, its armour was burned, scratched and had taken quite a hit from the looks of it, a dent stood in the middle of his chest plate, on its left shoulder was a MEDREF, Jack reached for it neck instinctively, he found a weak pulse, but a pulse nonetheless,

"Call a med team, this guy's still alive!" He shouted, Carter ran up next to him as she was the only one with first aid training in the room, General Hammond walked in to the gate room and noticed the portal had closed, leaving nothing to show it had been there, except the person that had fallen through, he watched as Sam and Jack removed the helmet while waiting for the med team, the man in the armour looked to be in his late twenties or early thirties, his hair was about as long as Jacks and completely black, he had what looked like claw marks running down his right cheek and went below his under armour, he had several smaller scars over his face, before he could get a better look the med team arrived and took him to the infirmary, he ordered for the box and weapons to be taken out of the gate room, he could see Sam pick up the aliens weapon which had deactivated and collapsed into a small grey and orange box.

Several hours later Jack walked into Carters lab to see her hard at work, he took a moment to admire her as she worked, she had the armour that was taken off of the man in the infirmary,

"So, Carter what are doing?" Jack asked after a moment, she looked up and smiled at him,

"I'm examining the armour that was on the soldier, it's really interesting from what I've been able to tell its made of several layers, it's under suit is made of Kevlar, protecting the wearer from most small arms, it also contains a heating and cooling systems, it's also coated with a heat resistant material to disperse heat, I's also pressurized to allow the wearer to operate in a zero g environment and in space. The outer armour is made up of a titanium and ceramic composite plating, further adding to the protection of the wearer. The helmet is made up of the same composite as the outer shell, it also has an on board computer, but I haven't been able to figure out how to access it yet. " She replied, however the explanation went straight over Jacks head,

"Cool, I guess, so have you figured out how that laser gun works yet?" Jack asked, after all it would give them one hell of an advantage if they could turn their opponents into ash with a single shot.

"Umm… I haven't actually been able to figure it out, I can't even get it to activate never mind figure out how it works." She replied, `Damn it` Jack thought,

"Have you found out anything about our mystery gust?"

"Well I did find a tablet inside the armoured rucksack but I gave it to Daniel to look at, and a flag under his chest plate," she replied helpfully,

"A flag? Really?" Jack asked, Sam just pointed to a folded up red and gold flag, it was folded in the standard thirteen fold. "Hey, Carter what happened to that big crate?"

"It's down in the armoury. When we cracked it open we found it full of weapons and ammo." She replied although she had gone back to examining the armours computer. Just as Jack was about to leave to have a look at the weapons from the crate Daniel walked in while still looking at a tablet, Jack guessed it was the one from the mystery soldier,

"Oh hey Jack, Sam you may want have a look at something I found on the tablet," Daniel shot out as thrust the tablet into Jacks hands as he was the closest, Jack looked at the tablet as Sam walked round the table to have a look, on the screen was a list of what looked like video files,

"Press the one labelled 'New Jerusalem" Daniel ordered, Jack pressed it and looked back at Daniel and saw that whatever it was had shaken him up a bit, he couldn't even look at the screen as the recording started to play. The video was from a helmet cam and if Jack were to guess he would say it was the mystery soldier in the infirmary , both him and Sam watched as the man dropped from orbit in what was basically a metal coffin with windows into a battle ridden city, which was called Mount Haven according to the signs around the city, they watched as entire platoons were wiped out by various different aliens, they could see the dead that had littered the streets no one was spared from the onslaught, even children were torn apart, some of them had been eaten by the looks of it, eventually the soldier was the only one left and had fund a crashed drop ship, with a dying officer nearby, the officer told the 'Rookie' his entire life story which gave the two Air Force officers some insight into his peoples culture, which from what they were able to tell from the man's story was at war with itself before the aliens or The Covenant as the dying officer called them ,arrived and started a holy war against humanity as a whole and how they started to 'glass' the human colonies. The cam shifted to look back at what was obviously once a very beautiful city being burned by massive ships that were floating above the city, dozens if not hundreds of drop ships and fighter were heading towards the soldiers position, the officer told the rest of his story, Jack was shocked when the man called Gage Yevgenny told how the soldiers in the bank lied to the children so they could get rich off of the gold in the vault and the betrayal of the men and how they killed a Colonel, it reminded him slightly of the time with Woods and Burke back in his black ops days. Gage then went on to tell the 'Rookie' to get the hell out of there as he was going to detonate a 'Shiva' nuke and blow them all to hell, Jack had to give the guy some credit he was going to sacrifice himself to stop the traitors and the aliens. The soldier dumped most of his gear including his helmet; the cam was actually through the eyes of the 'Rookie' as he had been dubbed, he then proceeded to run and didn't stop till he reached the other side of the mountain which was when the nuke went off, and the 'Rookie' looked back to see the mushroom cloud form on the other side of the mountain, the 'Rookie' then proceeded on to call for an evac. A drop ship like the one that had been found by the 'Rookie' landed and as he got into the troop bay he asked one of the soldiers in the back if there was anyone else from the 26th expeditionary force had managed to get an evac, one of the troopers shook his head,

"You're the only one we've picked up, we just got word that Reach has been glassed, all UNSC forces are to fall back to Earth, it's the only place left now." Jack was shocked, the trooper had just said Earth, "I think he might be from another universe sir" Carter state before he could say anything, "After all it would make sense as to what the portal was, except I have no idea how it would work or how to replicate it and send him back home."

"Yeah," was all Jack could manage, the video was truly harrowing even after all he had seen it still shook him; what he had seen on that recording. He looked back up at Daniel who had already seen the video, he looked like he was going to be ill, and Carter looked the same, the aliens they had been fighting had shown absolutely no mercy, even the Goa'uld weren't that bad. The phone on the wall rang causing the three to jump slightly, Sam moved to answer it, and Jack couldn't hear what the other person was saying but Sam just nodded and said that they'd be right down.

"Hey Jack where's Teal'c?" Daniel asked while Sam was on the phone,

"He's in the infirmary; watching over our guest." Jack replied, Sam had put the phone back on its hook and looked at the two men,

"That was Dr Frasier; our mystery guest is awake." She told them, and the three of them moved towards the infirmary.
