I would like to make an announcment. The OSA Council will be changed to the OSA Senate so as to not confuse between Citadel Council and OSA Council. The OSA Senate will still be the same people and size jsut the name is different.

Citadel

Council Chambers

The Citadel council was looking at the video a Salarian STG took of the complete failure of the Citadel fleet trying to retake back the Turian colony Bostra. The Council was shocked and scared beyond belief that the species they once thought was new and inexperience had powerful allies waiting to come to their rescue.

The Asari Councilor just looked at her other fellow Councilors, Valern was scared out of his mine for the possible return of another galactic war, as for Sparatus the look of anger was clear on his face that not only did this new race defeated the Turians once, but twice wounded his pride, a pride that could be the death of us all said Tevos while thinking to herself.

Sparatus could not handle the humiliation the Hierarchy could be feeling at this time "we must act quickly before they all come here and attack the citadel, we must call upon every species in Citadel space the Volus, Hanar, Elcor, and the Batarians to bring their ships here to defend the Citadel."

Tevos showed anger on her face and could not stand Sparatus any longer "First the Hierarchy sent ships to subdue this race and failed, then when they retaliated I voiced my objection to send the Citadel fleet to retake back Bostra and pushed for peace, but I was out voted and look what happened; now you want to bring in the other Citadel races to obviously fight not one race but a whole group, Spartaus they obviously have allies we can't fight all of them."

Before Sparatus could object her reasoning Valern stepped in "I agree with Tevos we can't risk another galactic war."

Sparatus could not let this happen "if you think the Hierarchy will go along with this you are clearly mistaken, we can win this if we put the entire Citadel races behind us."

Before anyone could say anything else Executor Anise reported to the council over the comm. "Councilors we have detected an unidentified fleet in front of the Citadel they are broadcasting a message on all frequencies."

OSA 4th Fleet

Sangheili Empire Repentant-Class Super-carrier "Seeker of Justice"

Slip Space

Heading to the Citadel, the center of galactic government for species around in the Mass Relay network was a fleet that encompassed all species from all corners of the OSA. The ship leading the fleet is the Arbiter Thel 'Vadam's Repentant-Class super-carrier the "Seeker of Justice". Onboard the super-carrier, the OSA ambassador a San 'Shyuum was discussing her plans for how she should handle the Citadel Council with the UNSC ambassador Donnel Udina.

"Arbiter, we will soon exit slip space in front of the Citadel."

The Arbiter was pleased…now he will finally confront these disgraceful cowards. "Very good… once we exit the portal, open a communication on all frequencies; it's time we revealed ourselves to the rest of the galaxy."

When the entire OSA fleet of 400 vessels dropped out of slip space, the entire Citadel defense fleet was on high alert before moving in to intercept, but were ordered not to attack. The Arbiter got up from his chair and moved close to the holo-projector. He saw how big the Citadel was, a Sangheili nearby just chuckled at the thought of how much bigger high charity was compared to the Citadel.

The Arbiter then took the stage in front of a microphone—this was the moment he was readying himself for. "Attention Citadel Council, this is the OSA ship 'Seeker of Justice'. one of your member species the Turians attacked one of our allies, humanity, for breaking a law they had no knowledge of and spilled the blood of their people; instead of going to war, they waited for the hand of peace. Instead, the Turians attacked them in force and were repelled. Humanity then responded to this attack by attacking a Turian colony trying to send a message to you to force the Turians to peace; instead you joined the Turians hoping you could overpower them, but you were unaware that Humanity had allies and were a part of the Orion Systems Alliance. We have come here today to prevent any more bloodshed, but if you refuse and continue this war we will not hesitate to destroy your Citadel."

The OSA fleet waited until the Asari Councilor opened communications "I am the Asari Councilor Tevos, and may I be the first to apologize for the actions of the Turians—this has been a huge misunderstanding, if you would give us a chance to open a dialogue between our two governments, we could resolve this."

The Arbiter was pleased his words reached out to the council "We will be sending ambassadors to the Citadel to negotiate a Ceasefire." The Arbiter disconnected the comm. link and turned to his fellow Sangheili "Report to the ambassadors that they are cleared to leave on a phantom along with their Honor Guard."

Citadel Docking

The phantom carrying the ambassadors along with a contingent of Sangheili Honor Guard had made it to the docking bay. Sangheili Honor Guard were among the most skilled of all Sangheili warriors and were hand-picked for the duty of protecting the OSA Senate and other high ranking officials in the OSA, having had their roots in the Sangheili Imperial Guard that had existed to this day—all of them were given the choice of joining the OSA SPECOPS division before they became members. They were joined by a team of Spartans en-route to the Citadel docking bay, they were greeted by a group of Asari and Salarian C-sec officers along with an Asari executor.

"Hello, I am Executor Anise, head of Citadel Security. I welcome you all to the Citadel."

The ambassadors just nodded. It was Udina that was the first to speak. "Are you the one who will take us to see the Citadel Council?"

"Yes, right this way please."

The large group walked through the presidium where every species lined up to see the group calling themselves the OSA that put the Turians in their place, the group could overhear what the Citadel races were talking about. "I can't believe the Turians went this far they could have started a war." said an Asari, watching as the group moved towards the Council Tower.

The Salarian next to her nodded…his fascination with these new species was due in part to his duty as a scientist. "Yes I agree, I hope this new race doesn't judge all the races of the Citadel."

Nearby, a Volus was also watching from outside his place of employment, which happened to be a bank. "Do you think... they will join... the Citadel?"

Council Chambers

As the species of the Citadel talk about the OSA, the ambassadors ride in an elevator up to the Citadel Tower. The group then made their way to the Council Chambers where they saw three individuals across a unlink bridge waiting on the arrivals. The Asari Councilor was the first to speak "welcome to the Citadel, and may I be the first to apologies for what has occurred between our governments this has been a terrible misunderstanding."

The OSA Ambassador of Obligation was a San 'Shyuum was sitting in her anti-gravity chair surrounded by her Honor Guard. Her expression was very solemn as she spoke of the grievances suffered by the Council. "The OSA Senate would agree with you Councilor, but not after we learned why the Turians tried to subdue the human world of Shanxi."

The Councilors looked confused by this, before anyone could say anything Obligation raised her hand for silence before she continued. "My associate can explain."

The UNSC ambassador stepped forward along with his Spartans, and began to speak "According to the information we obtained in the failed attack by the Turians, their mission was to attempt to not only subdue our colony, but to take any and all technologies from us to increase their authority in Citadel space."

The Citadel council was surprised by this and Tevos took the stage before Spartus did…much to the Turian Councilor's displeasure. "This is a serious accusation ambassador; we would need more proof then your words."

Udina was not surprised by this; from the information he had gained in the Codex, the Citadel Council rarely took any action without evidence to do so. "You want proof? Well here it is." It was here that he lifted up a data pad that contained the information ONI and the AI's had obtained when searching through their systems. A C-sec officer took the pad and handed it to Tevos, she downloaded the information into her console and sends it to the other councilors. By the time they were finished reading the document, they were all wide-eyed by this revelation.

Sparatus could not stand this accusation against his people…nor was he willing to go down without a fight. "This could very well be a trick from them; the Hierarchy would never do this, and I am curious to know how you could obtain any information from our ships as they are well-protected by the most advanced VI programs and firewalls."

This was the moment Udina was waiting for…his grin had promised a world of pain for Sparatus as he began. "Our Artificial Intelligences were able to break through all defenses and gather the information. Your VI programs could not stand a chance!"

The Citadel Council was shocked by this new information…the look of rage on Sparatus' face was very clear, and the following tirade only served to reinforce his anger. "YOU HAVE A.I.'s! DECOMMISSION THEM NOW BEFORE YOU KILL US ALL!"

The nerve of him…to demand such a thing from the very race that defeated his own! Udina was most definitely not going to back down from an angry Turian. "We will not decommission our A.I.'s because of the Councils paranoia over the idea that all A.I.'s will turn on their creators."

Before Sparatus could say a thing Tevos stepped in to cool tensions "Please you must understand are concerns, for a new space fairing race such as yourselves you don't know the dangers when it comes to A.I.'s."

"You must be mistaken!" said Obligation, "Humanity has been a space fairing race for nearly 500 years and my species has been for over 4000 years." Udina stepped in "And in that time our A.I.'s have never turned against us."

"Yes your A.I.'s have been obedient thus far, but how long until they turn on you?" asked Valern, his paranoia kicking in quickly. Udina and Obligation were getting annoyed by this continued argument over their use of A.I.'s. Tevos seeing how this bothered the ambassadors quickly tried to calm everyone. "We are only trying to make sure that history doesn't reapeat itself like what happened to the Quarians."

Obligation could only huff in disappointment. "We are aware of what happened to the Quarians; you kicked them out of the citadel when they pleaded for help. That in itself is something the OSA would never do."

Oh he was not going to have any of it. Sparatus simply let out a grunt of conviction—there was no way he was ever forgiving them for what happened. "The Quarians broke our laws when they created the Geth, and so they are being punished for it."

Before the meeting could escalate any further and off topic, Valern had simply remembered that there was mention of the OSA. The concern had betrayed his voice as he spoke. "Before your arrival, you said the OSA would not allow it. What is the OSA?"

This is where Obligation stepped in with a smile on her face. Now they would know who they were! "The OSA, or Orion Systems Alliance, is a collection of different species from the Orion Arm of the galaxy who have banded together to form a galactic government similar to your Citadel. For more detailed information, we created our own version of your codex." She then transferred the information to the Councilors' consoles. In it was only the basic information about each of the different species, their cultures and religious beliefs, along with the history of the OSA.

The Councilors looked over the information, and were surprised by the accomplishments and to their great shock the mysterious Forerunners and their great accomplishments. Tevos was the first to speak…and her astonishment was clear in her voice. "I am impressed how a group could accomplish all this without the guidance of the Citadel Council."

Spartus was not so pleased…his envy could only be rivaled by his anger. "This is absurd," he said, "there cannot be two galactic governments! And from what I have read, they barely even existed for over a century while the Citadel Council has existed for over 3000 years."

"I agree with Sparatus on this one," began Valern, "you have done well for yourselves thus far, but the responsibilities with forming this OSA may be too much for you to handle."

''You should consider joining the Citadel,'' said Tevos, ''we could learn much from each other, but of course their are certain conditions you must follow before joining the Citadel.''

Udina knew this was going to come up sooner or later, and he had a lot to say ''your demands and conditions to be a part of this Citadel are ridiculous! you ask the races that want to join to limit their ships size and numbers, and you out law AI's! I am afraid we will not join.''

Obligation was pleased with herself as she grinned at their reactions. "You'd be surprised at how long my kind and the Sangehili first took responsibility over the other races in the Orion arm, but we did not come here to see who is superior we came for a ceasefire."

Tevos could only nod her head in assent. "I agree, we have gone off track as to why we are all here this very day."

Sparatus knew that this was going to be switched back to them. Oh he was not going down at all! "I will not agree to anything until they return all Turian prisoners and are colony back to us."

"We never intended to keep your people or your colony," countered Udina, "we'd be glad to give them back to you with some stipulations."

"You are in no position to make demands of the Council, ambassador!"

Obligation was not pleased by the Turian Councilor's arrogance. "Neither is the Citadel Council in a position to make any demands of us."

Before both the ambassadors and Sparatus could say anything else Tevos stepped in. "We understand, and we will listen to your conditions."

Valern and Sparatus were not happy that Tevos caved in so easily to them, but understood that this could only go on for so long. After seeing the other Two councilors not objecting to the Asari, Obligation began. "First of all, the Turians will cease any further plans of attacking the UNSC and entering their territory. Second, the Exodus cluster and surrounding systems will be under OSA control for joint colonization. Third, no Citadel ship of any kind and race will be allowed entry into our territories unless they have an official permit or approval—the OSA will show the same courtesy. Do you agree to these conditions?"

The Council took a moment to converse with each other privately. After a few minutes, it was Tevos that answered. "The Citadel council agrees to these conditions, under the assumption that you will return what Sparatus has asked for."

"We will return the prisoners and the colony Bostra back to the Turians, after we have signed the agreement," said Obligation "and as a gesture of our goodwill, we offer you the opportunity to bring any ambassador of your choosing and take them to meet the OSA Senate on board our capital of High Charity—the opposite of your Citadel Council as a way to bridge the gap between our governments."

Tevos was glad that they had come to an agreement. There would be no more bloodshed for a while now that this meeting was over. "We would be glad to send ambassadors to meet your leaders to further open a dialogue between us and them."

Valern agreed only because he wanted to learn more about the OSA through his STG operatives. As for Sparatus, he was not pleased by this olive branch of theirs, but agreed anyway…because for today, the battle was in favor of the OSA.

Citadel Tower

Council Chambers

After the meeting was over and the Council signed the treaty, they chose their ambassadors to go along with the OSA ambassador to meet the OSA leaders. The council is looking out their window at the OSA fleet at their form of FTL travel now known to them as slip space. The Salarian Councilor was reporting the unsuccessful attempt of placing tracking devices on their ships. "Our attempts have failed—their form of FTL travel is not the same as ours."

Sparatus was not at all happy about this as he slammed his fist onto the armrest of his chair. "How could we be pushed around by these newcomers so easily? The people of the Citadel will begin to question our authority and power; some of them may even leave and join the OSA."

Tevos was never in agreement with Sparatus until now. "I agree with you, the OSA have caused changes in the Citadel, we must now be aware that we are not the only form of galactic government in the galaxy."

Valern then had an idea. "I believe that we must search for Forerunner technologies in order to retain our own superiority."

Sparatus almost forgot about the Forerunners…he could only grin in triumph. "Valern has a point, the OSA was able to gain much from studying their technology, we should be able to do the same."

Something about this arrangement had given her a feeling that this would one day come back to haunt them, but Tevos could not doubt the legitimacy of their claims. "I agree with both of you, but we can't turn a blind eye from the OSA. We must glean information on their technologies as well. The future of the Citadel is at risk of collapsing."

OSA Space

High Charity

Senate Chambers

The OSA Senate was looking over the successful negotiations between their ambassador and the Citadel Council. As they waited for the Citadel ambassadors to further continue negotiations. Senator Soha 'Rolamee voiced his opinion on bringing the ambassadors to the station. "Why are we continuing our talks with them? We have nothing more to gain from them."

Anita Goyle understood Rolamee's annoyance of still talking with the Citadel Council. She too was confused as to what the point of it was. "Soha, we may not gain anything of value, but we gain a lot for our people. We could setup trade between us and them, and of course we would have to place certain restrictions on what to trade."

The San 'Shyuum Senator of Tranquility was more concerned about other things "Why did we put information about the Forerunners in the codex? They could attempt to acquire their technology and use it against us."

"First off, the Forerunners placed a sort of lock on their technology that requires either a Forerunner or a Reclaimer to activate them. Secondly, we know the location of every Forerunner cache in the galaxy thanks to the Ark, so we have nothing to worry about."

"I beg to differ," said Tranquility, "the San 'Shyuum were able to access forerunner technologies with the help from the Huragok. If they locate one of them, they could easily acquire any information from them."

Goyle scoffed, and for good reason. "We don't have to worry about that, since all the Huragoks are under our control and we know the location of each one—we can trust them not to divulge any information to the Citadel."

"Still we should do everything in our power to keep their filthy hands off of are Gods' creations," continued Tranquility, "it would be heresy to not do anything—not to mention the dangers posed if by some act of chance they manage to unlock the technology."

Rolamee shook his head in irritation. "I may not agree with everything Tranquility had said just now, but I do agree that we need to make sure they don't get their hands on any Forerunner technologies in case they unleash the Flood…it's only a matter of chance for them to free the accursed parasite."

Anita could see they weren't going to let this go. "Alright then, we can get our Intelligence division to keep an eye on the Citadel Council in case they find Forerunner caches. But the thing that bothers me the most is if these Mass Relays are supposed to be everywhere in the galaxy, why we didn't find any in our home systems?"

'Rolamee and Tranqulity only had looks of questions too on their faces.

"I have a feeling the Forerunners had something to do with that." said Goyle as she continues to think it over again "why don't we just find out? Mendicant Bias, would you please tell us if the Forerunners had anything to do with the Mass Relays?"

Mendicant Bias was an AI of the forerunners that turned on its creators during the Forerunner-Flood War, but was defeated by its counterpart Offensive Bias and his mind was split into pieces one going straight to the Ark and the others on Key ships. When Humanity reconstructed the Covenant, they discovered the Forerunner dreadnought and aboard it was a piece of Mendicant Bias. The day they reached the Ark, they brought both the piece they had and the one on the dreadnought together—he became grateful and ashamed at the same time wanting to atone for his crimes against its creators. He was made High charity's AI, but the problem was that he only listened to the Humans, or Reclaimers, as he liked to call them.

"Of course Reclaimer," said Mendicant Bias, "I am afraid I have no information on the Mass Relays, or if my creators had anything to do with them. But I believe the answers you seek may be on the Ark."

Anita was a little disappointed. "Very well then, open a slip space communications link to the Ark."

Mendicant Bias did as it was told and a holographic image of the head director for the Ark appeared "Senators to what do I owe the pleasure of speaking with you?" asked Professor Anders, surprised to see the OSA leaders.

"Professor Anders, you must be aware of what's going on in the galaxy even if you are 262,144 light years from the galactic center we still keep you appraised of everything that goes on in the universe, do we not?"

Anders wasn't pleased by this statement…but at the same time, she wanted to know exactly what they were getting at. " Yes I do and you have to understand Senators that the Forerunners had tremendous knowledge in their data bases we have only begun to scratch the surface what's in here, and also the language between our two civilizations are drastically different."

The look of befuddlement was clear in Goyle's face as it was in her voice. "Is the AI of the Ark not helping you?"

"Offensive Bias has been a tremendous help in understanding some of the knowledge, but it has restrictions to some of the information contained in the Forerunners' Database. There are also passwords and codes that have been put in place by the Forerunners that are restricting information, but luckily for us they did not put any in the Index that contains the information on all sentient species' biology. We found the Citadel species catalogued in it along with us."

"That still doesn't explain about the Mass Relays."

"Maybe the information is locked in there like she said," suggested Rolamee, "which only brings us to another concern; why would they keep it a secret?"

The negative shake of her head told them everything. "I don't have answers for that, not yet anyway my team and I will keep looking and try to break the code." It was there that communications were disconnected on Anders' side.

The Senators all agreed to end their conversation here and began getting ready to meet the Citadel ambassadors.

Earth

Sydney Australia

High Command Facility, Bravo-6

The UNSC Security Committee was going over their plans for the future on what to do now that the OSA has revealed themselves to the rest of the galaxy. Anthony Hood could see the other members of the Committee were not happy how this turned out between them and the Turians. VC Morris spoke his mind. "We should have demanded reparations for the damage to the Shanxi Defense Fleet…instead we ask them not to come into our territories anymore. Talk about a slap on the wrist."

Hood knew this was going to come up as he sighed. "The reason we didn't ask is because they didn't attack Shanxi directly. Also, they didn't ask for reparations for the damage done to Bostra."

"What about their attempts at trying to steal our technologies?"

Hood was getting annoyed by the VC. "During our attack, we were able to acquire some Turian technologies so it's a win for us, do not drag this any longer and let's move on to important stuff."

Hood turns to General Young. "How are our forces coming along at Bostra?"

"The second fleet, along with the OSA have cleaned up the battlefield of any destroyed UNSC ships, so we don't have to worry about the Turians salvaging anything from it. all ground forces and equipment have been picked up and we are currently in the middle of returning the prisoners from Shanxi to the Citadel as per the terms for our conditions."

Hood was pleased by the success of everything thus far as he lit a cigar. "Good, that takes care of that. Anything else we need to discuss?"

"Yes there is," said Ackerson, "The director of ONI would like more funding for a new project he is creating."

Hood was surprised by this request that he almost dropped the cigar from his mouth. "Remind me again who is the director of ONI again?"

Ackerson pulled up a file of the director, but with no picture and some of the information is blurred out from the holo-projection. "Leonard Church was once a former ONI agent; one of the best, he moved around from different branches of ONI, but at one time he worked under Catherine Halsey in Section Four at the Ark, until the unexplained accident that took the lives of a dozen scientists and the disappearance of Halsey along with half of Section Four's personnel. Leonard Church is also responsible for some of the technologies we use today."

Hood was impressed by the director's success in ONI. "Ok what is this project he wants to create?"

"I'm afraid I cannot reveal anything about Project Freelancer, only that it's a necessity to secure and protect the interests of the UNSC."

Hood was not at all about to give up anything that will protect the UNSC, but he knew all about ONI—they never did anything unless there was something in it for them. "Very well, tell director Church he has his funding, but I want to see results by the end of the month, am I clear?"

Hood along with the other members stood from their chairs and walked out of the room.

Procyon System

ONI Space Station 3

The Office of Naval Intelligence was a division of the UNSC Navy that was responsible for counter-espionage, and it was under the jurisdiction of the Navy. ONI appears to report directly to HIGHCOM, but in the later years, they have only reported to the Director of ONI. It was responsible for intelligence matters across the UNSC, and as such, ONI employed members of other military branches, and even civilians, to complete the Division's shadowy work. They have spies across UNSC space and OSA space.

In the Depths of ONI Station 3 a man was sitting in a chair overlooking a holographic projection of the information gathered by his agents at the Citadel. He was concerned about the secret organizations that hid behind in the dark like the Shadow Broker, Salarian STG, and Citadel SPECTREs; they could be a threat to the UNSC and OSA. Before he could think any more on the subject, a man walked in the room. "Director, Agent Ackerson came through! The UNSC has sent over the funding we need to kick-start Project Freelancer, but I'm confused sir."

Church made his irritation at the counselor clear when he looked at the man with a barely-contained hatred in his eyes. "I do not pay you to be confused Counselor," he gritted out, "but all the same, enlighten me."

"I thought we agreed to wait three years to initiate Project Freelancer, why so early?"

"Fate has forced my hand; with the discovery of the Mass Relays, it has opened us to the rest of the galaxy along with the shady organizations that come with it. We need to prepare for what could possibly be a war in the making."

"Sir I am aware of the Shadow Broker—and while he seems like a threat, we can't keep an eye out in that region of space and still look out for ourselves…if we did, we'd be stretched too thin."

"That is why I am creating a new organization that will be the shield and sword for the UNSC and OSA from the darkness. A task force will be created between ONI and the UNION to protect the new joint colonies around the Mass Relays, eliminate threats to the OSA and UNSC, and provide intelligence for the new High Command in that region of space. They will be an army, a "Cerberus", established to protect all members of the OSA against outside attacks by any alien or organization, and I have the perfect person to run the organization."

"Who will it be Director?"

Church could only grin in pride. "He is my protégé and close friend—I will admit, he is a little distrustful of our alien allies, but he believes in the end justifying the means. He is a perfect agent to control the organization, but we will give him an alias—a code name if you will: The Illusive Man."

If you are all wondering why I put a red vs blue Project Freelancer in here is beacuse I liked the whole show and it was perefect to setup how to bring Cerberus in the picture also I will only use the characters from Project Freelancer no Red or Blue characters at all sorry Caboose fans. Cerberus will still have the same tacticus and ideals as the one in mass effect, the only difference is their will be aliens from the OSA that are part of Cerberus, but the majority members are Human. next Chapter will be a timeline like the first chapter just to Speed things up, so I hope you have enjoyed this chapter and write back tell me what you liked and didn't.

Codex- OSA Alien Races

San 'Shyuum-The San 'Shyuum have no form of government other than the OSA Senate. The majority of their species lives on High Charity which makes them an endangered species. The San shyuum were once a frail Species unable to perform basic work thanks to humanities understanding augmentation they are no longer a frail weak species, but capable of a lot of things, but high ranking officials still use anti-gravity technology to show off their superiority.

SangheiliEmpire- The Sangheili government appears to be a feudal meritocracy, and is partially democratic, as elders of different states rule different areas. The ruler of these areas, a Kaidon is elected by a group of council elders that reside in that area—none of them are above the emperor. If a council elder believes that his vote was "ill advised" or "had second thoughts", it was considered a tradition for council elders to initiate some form of attack, such as sending assassins, against the Kaidon in order "...to test the true merit of [the] ruler's martial abilities." The belief was that "a Kaidon who could not defend himself was not a true leader." Should the attack fail, the responsible elder will be executed immediately, and his family will be killed. However, punishment for this form of heresy was usually flexible. As such, if the elder did something honorable, such as attack the Kaidon himself, or attempted to make a final stand against the Kaidon, then he would probably have managed to save his family from certain death, although they might still be banished.

Jiralhanae Tribal Confederacy- The Jiralhanae Clans is ruled by the five most powerful chieftains who meet at a neutral location to discuss galactic politics and the future for their people. Some would say that this is a new form of government compared to the old standards they lived by at one time, but thanks to the OSA influence they have changed much.

Mgalekgolo Commonwealth-The Mgalekgolo are the strangest aliens in the OSA because of their form communication and each Mgalekgolo being a gestalt creature made of worms known as Lekgolo. Their bond with the Sangheili runs deep, as they have a great respect for their fellow warrior-race.

Huragok-The Huragok have no form of government created by the Forerunners they are incredible engineers and are stationed on every OSA and UNSC ship.

Yanme'e Hives-The Yanme'e are insect like species. Their form of government iscontrolled by Queens who are never seen outside of their home world, but continue to be a part of the OSA.

Kig-Yar Trade Union- The Kig-yar government on Eayn is a post-industrial capitalist system, with a population of 978 million. It is also described as an ochlocracy, a system of government best described as a government by mob, or the intimidation of constitutional authorities. Presumably, this implies that whatever form of local government the Kig-yar possesses is ineffective and ignored. In their early history, they were once pirates that attacked supply ships and preyed on colonies—when the OSA was formed, they put the kig-yar pirates down hard with the combined OSA fleet and outlawed piracy.

Unggoy Republic-The Unggoy are unable to build ships of their own so the OSA puts the entire Unggoy race and their worlds under their protection. In exchange for this they offer their service by help developing colonies or in unloading or loading of supply onto ships.
