Hello everyone this is Nagato21

I am please to present you my first Stargate fanfiction :Stargate Unbound

For starters this story is heavily AU, it is set in the distance future, the 23rd century. In this setting, Earth never discovered the Stargate or rather they never suspected it's importance. However they did discover bits of Alteran technology which they use to advance their own further and develop hyperspace travel.

Many characters from the franchise will appear in this story and some will be similar in character as seen in the TV but there will be a lot of OCs, so for those who don't like it, you are free to live but please try to be open minded.

I apologies for some of the mistakes and spelling that might occur and I promise to do my best to correct them.

Now enjoy and please review.

February 12th 2185

Epsilon Secondus sector, Terran Alliance territorial borders

TAS Battlecruiser: Hammer of Intent, flagship of TBG-23, 8th Frontier Fleet

En route to Star System SX-B12378-Sigma Outpost 281

For the hundredth time, Commodore Susan Ivanova growls as she is fighting a losing battle against the bane of all career officers: Paperwork. Despite advances in computers and the advent of neural interface, signing, approving and reviewing forms was still a chore. Ivanova knew it was one of the many prices to pay when in command of such large battle group especially in such crucial mission.

Thirty six hours ago, the Research outpost Sigma 281 in the uncharted Epsilon Secondus sector had sent a distress signal before ceasing all communications. A recon Frigate the TAS Pollux from Picus Anchorage in Epsilon Eridanus star cluster had been dispatch to investigate. Six hours later, the frigate had sent its own distress signal and a Hotel-Charlie-0 code which meant in Alliance military code: Hostile Contact, meaning they had encountered a hostile alien life form. Afterward the frigate had ceased contact.

High Command sensing the danger had immediately ordered the Frontier Fleet to dispatch a battle group to investigate more thoroughly the situation. However the President did not want to risk a full inter-stellar war before learning more about their aggressors, so a member of the Terran Ministry of Affairs was on route to meet Ivanova's battlegroup and attempt peaceful contact

Ivanova snorted at the thought, the embassador would arrive to late and beside it might already be futile. The Pollux before its destruction did not just send a distress signal; it also sent an encrypted stream of data of its encounter with the unknown. Four ships with tetrahedron shape and a pyramid at the center like the one built in ancient Egypt. Those strange alien ships had opened fire the moment the frigate came in orbit of the planet. The Pollux managed to fire back but its small armament bounced on the ships, revealing they had energy shields. The Pollux attempted to flee and somehow outrun the ships but it was chased by another group of six ships, smaller than the frigate but very fast and also equipped with energy shields. With half of its weapons destroyed or useless, the Pollux was destroyed along with its two hundred crewmen. The entire battle lasted ten minutes but the trove of information sent by the Pollux gave an idea to High Com what they were facing and it wasn't encouraging. They were dealing with a technological and very aggressive species. The Terran Navy sported energy shields but the power requirements for such device was so huge that only the eight kilometers long Saratoga class Heavy Carrier or the fifteen kilometers long Hecatoncares Battlecruiser like the Hammer of Intent could sport them. Even then those shields were not proper shields but design to deflect energy base weapons and could barely stop solid kinetic type weaponry. From the analysis of the alien ships their shields was plasma based unlike the Terrans who used Ion energy shields. Luckily Ivanova's battle group TBG-23(Terran Battle Group) was carrying a large stock of Neutron warhead missiles codename Widowmaker, design specifically to nullify energy shields and also discharge powerful EMP waves into a ship's subsystems. If it didn't work the fleet was still armed with powerful plasma weaponry on par with the aliens and also had fusion beam canons and Particle Accelerator Canons as well not to mention fusion nuclear warheads.

'We have enough firepower to level an entire planet six times over' Ivanova thought 'they will have to think twice before engaging us'

Unlike the regular fleet, the Frontier Fleets were design to act as the eyes of the Terran navy by patrolling trading lanes and the edge of the borders of the Alliance; also act as a response unit against potential hostile enemies. As such they were more independent, flexible and could operate in deep space for longer period of time. There were a total of nine fleets, each was divided into six battlegroups of fifty nine ships each, consisting of 12 frigates, 25 destroyers, 16 cruisers, 2 Carriers led by two Battlecruisers and supported by one Hospital ship and one Mobile Shipyard. It was a powerful force and would send a powerful message to anyone who would dare challenge the Alliance. Although many had criticized the need to have so many ships, the Chaos War which had devastated most of the Alliance sixteen years reminded many that without a strong military, humanity might have gone into an unprecedented dark age of violence and blood not seen since the Middle Ages.

A low buzz interrupted Ivanova of her thoughts; she reached the console on her desk and pressed a button.

"Ivanova speaking"

"Commodore this is the bridge" replied a voice she recognize as her XO, Robert Elland

"We have just received the telemetry from our recon probes; I think you should come see it"

"On my way" Ivanova turned off the communication, got up and adjusted her uniform, which was a dark blue skintight jumpsuit, the chest, arm and leg joints were reinforced with extra padding. The suit itself was made of nano-fiber composite of E-carbon and Trinium, while seemingly light, the suit could stop bullets from an assault rifle or even low power energy pulse weaponry. Furthermore the suit contains an onboard medical maintenance system, consisting of a special cocktail of drugs and enzymes design to prevent rapid blood loss and give accelerated regenerations of organs, all maintained by a semi-Artificial Intelligence system design to monitor the wearer's life signs.

Ivanova grabbed her jacket and left her cabin, at the door exit stood two Terran Marines who stood at attention. Like all Terran Marine Corp, the two men were tall, measuring nearly three meters, a byproduct of genetic enhancements following their training at boot camp under heavy gravity. Terran Marines were not normal soldiers; they were super soldiers or in their terms, super beefed up Marines. Their reaction times was three times faster than a normal, they could lift up to eighty kilos of material on their back and run a hundred kilometers marathon barely breaking a sweat. Special neural implants allowed them to see better at night, their ears could pick a needle dropping in the sand and their blood contained special regenerative enzymes that would help heal most fatal injuries, not mention making them immune to all known form of chemical and bacteriological agents. Ivanova had even heard rumors that some were immune to nuclear radiations. In other words, Terran Marines were the greatest soldiers ever created by humanity, but they were not all just muscle and power. The Terran Marine Corp was comprised entirely of volunteers and they all followed a strict if not almost fanatic code of conduct that ensured that never they would abuse their amazing abilities nor harm civilians unless threatened. In the early days of the Alliance the Marines had been seen as distrustful and dangerous but time and time again they proved to be anything if not honorable men and women. Ivanova had experience with Marines during the Seth Crisis; religious fanatics had attempted to overthrow the Alliance in a campaign of terror using nuclear, chemical and biological weapons. Two hundred million people had died and three million Marines had given their lives to end the fanatics' reign of terror.

At her presence, the Marines saluted her; she replied with the same gesture and continued toward the lift, the Marines in tow. During the Chaos War, many Alliance officers had been assassinated or brainwashed, half of them by infiltrators and sleeper agents onboard their ships, the other half by booby trapping their cabins, poison in their drinks, or sabotage of their ship's fusion reactors. Since then, the Marine Corp protected their senior officers with extreme zealousness and would constantly perform sweeps of living quarters to search for anything remotely dangerous. If the strict bio-scans done regularly on a ship, naval base, government facilities were not enough, surprise inspections onboard warships and stations were the norm, even though the war ended some sixteen years ago, the Marines, Terran Naval Intelligence (TNI) and the Terran Law Enforcement Agency (TLEA) were still searching for sleeper agents and secret worshippers who were still wrecking havocs in the outer colonies.

It took two minutes for Ivanova to reach the bridge via one of the two electromagnetic powered lift that travelled all along the ship's spine. The bridge was located at the heart of the ship and also contained the CIC in order to coordinate the various ships comprising the battle group. Shaped like a hexagon, the area was heavily armored and protected not only by several thick doors made of Trinium and Carbon composite but also automated gun turrets, robotic sentries and a full platoon of Marines, the bridge itself contained an armory for emergency purposes. At the center of the room was a circular shape holoprojector displaying the ship and all of its surrounding across several thousands of kilometers, tags of various color describing allies and objects of various size and types. All around, rows of consoles attended by crewmen sitting in their chairs or standing. Despite being a starship, the Hammerhead class Battlecruiser had no command chair in its bridge, not a design oversight but according to many Alliance officers during the ship's conception, one didn't have time to sit while conducting a war. Instead the Captain's time inside was taken by leaning on the fence bar surrounding the holoprojector, from there he/she could keep an eye on the people and the situation around the ship.

As she entered the bridge she was greeted by Elland, a black skinned man well built with a shaved head and a small goatee.

"What have we got?" she asks in her usual business tone as she approached the holomap

"The recon drones have spotted several energy signatures in orbit of the fifth moon of the seventh planet. Their signature matches those who attacked the Pollux." replied the XO as he typed on the console fixed on the fence to display the information on the holomap. The system where Sigma outpost was located was a binary star system comprised of a dozen planets, none were habitable and half were gas giants. The seventh planet was one of them and it was surrounded by hundreds of natural satellites and a large debris ring. Initial surveys had detected large amount of Trinium and the very rare metal call Neutronium which made the area a perfect place for future mining colonies and even shipyards. Plans were made to terraform the moons of the seventh planet and the Sigma outpost had been placed to make final studies before approval hence its presence in the area.

"How many?"

"Radiation from the gas giant and the binary suns is preventing us from getting an accurate reading however we can count so far a total of sixty five ships, thirty two of them are those pyramid shape vessels in size similar to our cruisers while the remaining thirty three are similar to those gunships that finished off the Pollux, aside from them we have detected smaller spacecrafts we assume to be either fighters and shuttles."

"Any sign of the personnel of the outpost or survivors from the Pollux?"

Each Alliance personnel were outfitted with a subspace transponder and a neural implant, which would allow monitoring their vitals as well location.

"None" answers the XO "However there are traces of debris and matter consistent with the hull of an Aeolus class Frigate. As for the outpost it is nothing more than a pile of ash."

Elland showed a picture a drone had taken of the small moon where the outpost was located, gone was the installation, instead there was a crater.

"Escape pods?" asks Ivanova

"The drones found six but all of them were damaged and their occupants dead. The cause was due to impact from the debris of the Pollux and also traces of... plasma hits." he trailed, implying that the aliens had given them no mercy.

"ETA until we reach the system?" she asks

"Two hours?"

"Excellent. Signal the fleet that when we exit hyperspace to assume combat formation Delta-9. I want primary fighter squadrons ready to launch at a moment notice but no one is to open fire until I give the order."

"Yes m'aam" He obeyed and began relaying the orders through his neural hub to the communication officer who will relay it to the other ships.

"What do you make of those large ships?" she asks her XO pointing the pyramid shape vessels

"At first glance they look intimidating but according to the sensor log of the Pollux, their firepower is not widely distributed."

"Really?"

"Yes" nods Elland, he tapped a button on the console and the holoprojector displayed in grand size the shape of the alien vessel. "Scanners counted at least twenty high intensity plasma canons and thirty low yields plasma turrets probably for anti-fighter duties, but most of the heavy plasma is on the ventral section of the ship which generally implies a ship design for planetary bombardment but..."

"But it's too big" finishes Ivanova, she had to agree with him. At first glance the ship seemed to have enough firepower to rival a Metropolitan Heavy Cruiser but the emplacement of its weapons made the rate of distribution uneven. In the case of this alien vessel it would need to show its ventral side if it wanted to unleash large amount of damage against an enemy ship of similar or superior weight. It could be a bombardment ship but its size was too big and according to the scanners its power source did not take that much size.

"Could it be a troop ship?" she asks

"To be honest Commander I don't know what to think" he sighed "Hopefully we will get our answers when we arrive."

Ivanova nodded but interiorly she hoped it would not require a rain of plasma and lasers to obtain the answer.

"Notify the carriers Apollo and Demetrius to arm all of our bombers with Widowmakers, they are going to be our ace in the hole against their shields if we fight them." she ordered.

"You mean when we fight them?" it wasn't really a question; both officers had enough experience to know that the moment they exit hyperspace the aliens would fire upon them. The brutality they had showed in destroying the outpost and the Pollux attested to that.

...

SX-B12378-above the remnants of Sigma Outpost 281

Lieutenant Alexander .Jr. Sheppard wondered if his current predicament was god's way of making him pay for all of his misdeeds with a certain admiral's daughter. The admiral in question had not been happy that his only daughter was shacking up with a lieutenant naval space pilot who had history of insubordination, misappropriation of military equipments, followed by a string of infractions and insubordination as long as the Orion Arm of the Milky Way. To resume, Alexander Jr. Sheppard call sign Madcat was troublesome fellow, despite being one of the best pilot in the Terran Navy, he had made a lot of enemies which would have been cause for demotion and dishonorable discharge, unfortunately or fortunately Sheppard also had some incredible stroke of luck as well as very powerful friends and was a decorated officer, in addition of being a national hero for his performance during the Chaos War. One particular fit had been to cause a Seth cultist combat group en route for a populated colony to shoot against each other thanks to Sheppard flying between the tight formations of ships and insulting on all frequencies about their God. Suffice to say the cultists had never been known for their anger managements and began to fire all weapons in an attempt to eliminate the blaspheming fly call Madcat. It didn't turn pretty well for them and by the time reinforcements arrived, half of the combat group had been destroyed by their own weapons and still cursing Sheppard's name. The man became an interstellar hero and poster child for the Navy to their greatest regret. None of the fame however could have saved Sheppard for owning to his past mistakes and after the war he found himself in a strings of transfer after transfer, from a Heavy Carrier to a remote base and now he was a pilot jock running supply onboard a shuttlecraft. Any attempt to transfer or even quit the Navy was forestalled because of his previous 'deeds' for an undetermined period of time. For six months Sheppard had been bored, living with a bunch of scientists studying rocks and theorizing about god knows what. His only entertainment was when he was flying survey missions on one of the many moons orbiting the gas giant. It never ceased to amaze him about the beauty of so many cosmic objects. Unfortunately his enjoyment had been cut when a fleet of unknown warships entered the system and began shooting at him and the research station. Sheppard had tried to outrun the fighters but he was piloting a civilian use survey shuttle, not a gunship. Rather than being dust, the aliens had crippled the engines and then towed the shuttle to one of their ships.

"Kal nesh troga!"

The voices took him out of his musing; four silver armor clad men wielding long staffs in their hands came dragging a blond woman dress in the traditional gray jumpsuit of a Terran Alliance researcher toward his cell.

"Lisa!" yells Sheppard as he got up, Lisa was one of the scientists at the outpost, somehow she had survived or they had captured her.

"Sheppard...you are alive" she gasp for a moment when the guards lowered the force field and threw her, Sheppard caught her, not before sending the guards dark looks. Not because of how they were treating them but because the mark on their foreheads while different reminded him of the Seth Cultists, not to mention they looked humans. His gaze caught the eyes of a young man dress in a more decorated and functional armor than his comrades. Sheppard could only guess he was a high ranking officer. However unlike the other 'Jaffa' as he heard them being called, this one's face had a slight mixture of confusion and curiosity, although he was doing a good job to hide it.

"Are you alright?" asks Sheppard to Lisa as he helped her seat on one of the couches.

"They killed everyone" mumbles the scientist "Bob, Carl, Stephanie...oh my god" Her head fell into her laps hiding her tears. Sheppard could only look away, a part of him wishing he could do something. He shook that thought out of his mind, if they wanted to survive he had to get it together or die trying.

"Don't worry Lisa; before they took me in I detected a distress signal being sent from the outpost, I bet reinforcements are on the way." It wasn't a lie either, Sheppard despite his exile maintained regular contact with his friends in the navy once or twice a week, so he knew that elements of the Frontier fleet were not far away. He just hoped they would arrive in time and had enough firepower to take out those bastards. However he needed to make sure they didn't go down with them.

"What are we going to do?" asks Lisa, still shaken but her face had brightened a bit. Sheppard despite her opinion of him being a redneck was a soldier and a very resourceful one.

"First we try to stay alive"

"A wise advice" spoke someone. Sheppard turned toward the entrance, behind the force field to see the same young man he had seen earlier.

"What do you want from us and who are you?" asks Sheppard

"I am Ryac First Prime of the God Apophis" spoke the young man with pride, but Sheppard could swear he smell coldness coming out of those words. However what really shocked him were Ryac's words. He glanced at Lisa sharing the same thoughts.

'Great another bunch of fanatics' thought the Terran pilot. Honestly he shouldn't have been surprised. During the Chaos war, the Cult of Seth had boasted some very advance technologies, decades ahead of the Terran military, in no small part thanks to Hathor Industries who had worked with the cult to control humanity. Many had theorized that the corporation and the cult had stumble upon alien technologies like the one found on Mars and used it to build their deadly toys."

"His lord Apophis wishes to see you both" continues Ryac "I suggest you do not resist" He gestured to the guards who pressed a button, lowering the force field.

Both Terrans were escorted across a hallway before reaching a small room with a circle in the center. Ryac gestured them to enter the circle with him, he pressed a button on his wrist and suddenly the circular ring rose from the floor along with several and a white light flash brilliantly.

The group found themselves in a new room and with barely a glance; Sheppard could guess they were on another ship.

"Incredible" mumbles Lisa, her fear and predicament ignored momentarily, letting place to the scientist in her. "This is matter transportation"

"Excuse me?" asks Sheppard a bit confused as they resume their trek, following Ryac across the hallways. Sheppard was now sure those guys were affiliated with the cultists due to the obscene amount of gold decorating the walls.

"A technology we have yet to master, we know the Alterans perfected it but so far our attempts have been less than successful." continues the scientist

"And somehow the bad guys always get the good toys" grumbles the Terran pilot, remembering his many battles against cultist fighters equipped with plasma canons and energy shields while he had to rely on railguns and time consuming laser weapons.

"By the way how come you are not using your combat implants?" asks Lisa "You are a soldier it shouldn't be a problem right?"

"Well for two reasons, one I am a pilot so my implants are different than the ones used by ground pounders and two we don't know what those guys are capable of yet so let's wait." Of course being called Madcat and having participated in a few black ops meant Sheppard had a few surprises in store that were outside the standard implant package given to Terran Naval Aviators.

Lisa nodded and Sheppard couldn't help but wonder were the fearful woman of a few moments had gone.

"If you ask me I don't think they are neither Seth Cultists nor Terrans" she said, her comment surprising Sheppard.

"Why not?"

"Well usually the first thing Seth cultists do when capturing a Terran military officer is to either torture him for information or place a neural inhibitor to jam the neural interface, preventing the use of their implants. Add to the fact that their plasma weapons look scary but they are less sophisticated and cruder than the ones used by the military or the snakes."

Sheppard mentally face palmed himself for not noticing, while he had never been a prisoner he had helped in liberating Seth prison camps and knew their MO, these guys were different. They didn't even have any cybernetic implants or augmentations that were favored by the cultists but he could tell they were stronger than an average human.

"How come you know those things?" asks Sheppard "I didn't peg you as being knowledgeable outside astro-physics."

The woman rolled her eyes "I am a Mackay which makes us knowledgeable about a lot of things and just before you start thinking I am damsel in distress I'll have you know I survived the Gideon IV Massacres, hence why I know how the Seths operates."

Sheppard visibly widen at the comment, the Gideon IV Massacres had been one of the bloodiest and darkest moments in humanity's history. He had lost many friends in that day; he could hardly imagine what that woman had gotten through.

The duo finally arrived in a large room that could only be the bridge as several individuals manned the various consoles, at the back of the room however there was a throne made in (no surprise) gold. Sitting on that throne was a man with brown skin, he looked like a perfect human male but Sheppard and Lisa immediately sensed something off about him, something inhuman. Those thoughts were confirmed when his eyes suddenly glowed white. Immediately they were shoved on the ground by the guards, while Ryac approached his master's side with a discreet bow.

"I am your god Apophis" he spoke with a voice that did not belong to the man but yet came from his mouth, clearly he was an alien.

"Nice to meet you" speak Sheppard with half a smile "I am your neighbor next door, how do you do"

Somehow despite being aliens, they knew when someone was being a smartass. One guard used the back of his staff to strike him on the back to remind him of his manners.

"Your tenacity is admirable but futile. Tell me where your homeworld is and I will spare your lives?"

Both Sheppard and Lisa shared a glance that conveyed everything they needed to say

"Alright but at a price" says the female McKay

"You dare treat me as an equal?" shouts Apophis his eyes glowing, the guards raising their weapon staffs

"What she means" starts Sheppard "is that we hope to become your servant my lord as you begin your conquest of those infidel mortals who dare challenge your might" he finished with a slight bow.

Apophis smiled, a smile showing the extent of his ego and greed. He liked this human, despite him and his kind being different than the others. He had been surprised when a few weeks ago one of his patrolling Hatak detected subspace fluctuations coming from Ra's former domain, a domain long abandoned since the war with the Asgard and then fighting against Anubis which had ended in Ra's death and Anubis disappearance at the hands of the Asgards. The System Lords had suffered terrible damage in this costly war against their own but they had recovered. As of now the System Lords where in a state of cold war, with Baal on the rise to become the Supreme System Lord and Sokaar who had returned from his own exile with stronger ships and troops. Apophis counted himself lucky as he managed to absorb some of Ra and Herur territories as well as some advance technologies to strengthen his fleets. However resources were dwindling and he could not afford to step into his rivals territories lest others used that opportunity to take him out. Thus he decided to send ships to scout the former abandon domain of Ra, where the legendary world of the Tau'ri was supposed to be. Tracking the subspace signals had led him to an uninhabitable system rich in Trinium and Naquadah. With those resources, Apophis knew he could build a hundred Hatak upgraded with some of Anubis technology he had acquired and perhaps a dozen Kartak model like his own flagship, paving the way for his domination of the galaxy. Not to mention that this region was quite isolated from the main Goauld holdings meant few would be aware of its location. But first he had to know were those humans came from and how advance they were.

He approached the man kneeling in front of him

"Tell me more about your home, mortal"

So ends the first chapter of the SG Unbound. We are introduced to Sheppard and McKay descendants and both share the some of the quirks of their ancestors. Ivanova is a character inspired from Babylon 5, one of my favorite Scifi TV shows. She is a badass and doesn't take shit from nobody.

There will be more development on Ryac in the following chapters and more will be revealed about the state of the Galaxy as well as the history of the Terrans.

Next chapter is going to have a lot of actions so stay tune.
