The Next Great Journey

A/N: Readers I would like to state here first that this is the first story that I write and also that English is my second language, so if you see any errors in grammar, punctuation, etc. please tell me about them I would highly appreciate that.

Now this story is cannon for the halo part of the story until the destruction of Requiem, in the Mass Effect part of the story in will be all AU except for some details (Timeline till 2155 is the same, Alien species, weapons, abilities, ships designs, the Krogan's, Batarian's, Quarian's, and Geth's place on the galaxy, the Terminus systems also will be exactly the same).

What you will mostly see and notice in the Mass Effect part of the story is that the council use more common sense and tactics to deal with a potential enemy that is superior to them in most of the space parts of battle but in equal terms of ground battle, also the council will be using a LOT the STG and SPECTRES to make illegal operations that will give them either more information on the enemy, or advantages in the cold war and total war parts on this story.

Now in the Halo part of the story you will notice that the UNSC and the UEG will rely more on ONI (after all they are the intelligence part of the military), also the Loyalist Covenant will be playing a big part on this story as will be the Separatist. Also do NOT expect to see Cortana coming back like a super AI that can do everything like a Forerunner AI, and also Master Chief will be part of the story but he will not be in all chapters and battles/operations.

The timeline will be for the counsel space the year is 2155, that's equivalent to the year 2557 when Requiem was destroyed.

This Chapter has been edited after some things got my attention as the one of the reader that informed me.

Disclaimer: I don't own Halo or Mass Effect both belong to their perspective owners.

Now onto the story:

Chapter 1: Timeline and Discoveries

2155/2557: After the destruction of Requiem, Infinity and its battle group of Strident class heavy frigates return to the Solar System.

2155/2557: High command of the UNSC discuss options to deal with Catherine Halsey's betrayal of humanity. In the end ONI sends prowlers to locate and eliminate her in order to ensure COLE protocol.

2156/2558: Covenant Loyalist forces attack the colony of Sanctuary in the perimeter of Separatist space in order to create a distraction for more Loyalist forces to enter UNSC space and establish an operations base. The fleet of Redeeming Souls is sent to recuperate Sanctuary with a fleet of 4 CAS-class assault carriers, 12 CCS Battlecruisers, 15 CPV-class heavy destroyers, and 20 SDV-class corvettes.

2156/2558: After 5 months of battle in the colony of Sanctuary, separatist forces win the battle after losing 3 CAS-class assault carriers, 5 CCS Battlecruisers, 8 CPV-class heavy destroyers, and 10 SDV-class corvettes. Loyalist forces successfully establish an operational base inside the Corelius nebula, hiding their signature presence to UNSC patrols, plans for an invasion to Earth commence.

2157/2559: Saren Arterius becomes the youngest SPECTRE after successfully stopping Batarian pirate forces of invading a Turian civilian colony in the edge of the Hades cluster without casualties to his battalion in the planet.

2158/2560: The UNSC and the UEG send a message to Separatist forces to have a conference above Earth in order to establish an alliance between them. During the conference an invasion fleet of Loyalist forces in slipspace is detected outside of the Solar System in route to Earth.

2158/2560: 10 minutes after detection the Loyalist fleet exits slipspace arriving to Earth, consisting of 40 CSO-class supercarriers, 60 CAS-class assault carriers, 68 CCS Battlecruisers, 20 CPV-class heavy destroyers, and 80 SDV-class corvettes. The Earth defense fleet with the aid of the Separatist endeavor engages the Loyalist fleet. After a close battle, the Earth defense fleet and the Separatist forces win against the Loyalist suffering a total of 60% of losses for the defense fleet and a 55% loss of the Separatist endeavor. After the losses are accounted for both sides the UNSC and UEG government, after realizing the great advantage that both have combating side by side against enemy forces established an alliance with the Separatist covenant forming the System Alliance (Noted that both of the ex-factions will still design their class of ships but will share technology, also their ships will have armaments from both Human and Covenant, their fleets will also have mixed personal and ship designs).

2159/2561: The newly formed System Alliance under covers the operation directed by ONI against the Sangheili government. In a fast move made by the newly Alliance, they managed to trap and kill the current leaders of ONI and all personnel involved in the operation against the Sangheili.

2160/2562: ONI is reformed and now is under the control of the System Alliance military branch the UNSC. Jason Patterson is appointed new head of ONI after showing impressive skills in all intelligence departments for time of war situations.

2161/2563: ONI stealth prowlers locate Catherine Halsey and Jul Mdama in unexplored space, Jason Patterson, leader of ONI, authorize the deployment of a SHIVA bomb to disable Jul Mdama's fleet to give spartan team Gladiator a window to infiltrate Mdama's ship to kill Halsey, capture or kill Mdama, and recuperate the other half of the Janus Key.

2161/2563: Spartan team Gladiator successfully kills Halsey but Jul Mdama managed to escape in a SDV-class corvette to Loyalist Space with the other half of the Janus key.

2161/2563: The Council authorizes the activation of relay 217 in order to acquire new resources for the implement of the Citadel fleets to star expansion in the galaxy.

2166/2568: In order to improve relations between the System Alliance races, the colony of Phoenix in the system Deca-5, is founded to improve relationships between alien races of the System alliance. Construction of Arturus Station commences, this will be the new capital of the System Alliance and will be located in one of the most protected systems inside their space. After 5 years of establishment and mining operations in the system beyond relay 217, renamed Prometheus, the Citadel Council begins construction of more vessels, especially dreadnoughts, saying that it is for protection when the expansion of Citadel Space continues and evade another Rachni war.

2170/2572: After 5 years since the inauguration of the Phoenix colony the relationships between former separatist covenant and humans have greatly improved at a level where there is respect and no hostility between them (It will take decades before most of the resentments of the Covenant war disappear), there is only 1% of the System Alliance population that doesn't believe in this cooperation and take hostile actions against them. Also in this time period of 5 years the System Alliance have been expanded in the rest of the Orion arm of the galaxy having control over 78% of the space in the Orion arm consisting in a total of approximately 950 worlds. Planets that where glassed during the Human-Covenant war have been terraformed to a point where in a few years would be restored to their pre-war status.

2171/2573: The System Alliance fleets have been restored to pre-war levels thanks to the cooperation between species and the discovery of 2 more shield words in their systems. Construction of Arcturus station is finished, it is located on the system Reincarnation. Citadel Counsel activates a second relay located inside the Prometheus system, once on the other end of the relay the Citadel encounters a colossal structure of the size of the orbiting planet and resembling a ring, STG, commandos, archeologist and 3 SPECTRES are deployed on the ring for study. Once insertion groups where detected on the ring surface the Oracle of the ring, named 216-Redeemer, activated a full lockdown of all installations on the ring after confirming that none of the species where reclaimers, stealth sentinels where deployed to observe the newcomers.

2172/2574: After the discovery of the ring the Citadel Council banned the activation of more relays to concentrate in the investigation of the most TOP SECRET discovery for Citadel government, the purpose of the unidentified object it's still unknown because of the difficulty to open the structures inside the ring and the defenses that the structures that they have managed to open have.

2172/2574: The System Alliance discovers an anomaly at the edge of the system Deca-5 in the presumed planetoid M4578S, Investigation group Foxtrot has been deployed to investigate the anomaly.

September 5, 2574, 2147 Hours, System Alliance Calendar, Deca-5 system, CPV-Class Heavy DestroyerESTEEM, Close to planetoid M4578S.

Shipmaster Orna 'Fulsamee observed the planetoid from which the proves sent where observing the anomaly, for the past hour his investigation group; that consisted of his CPV Class Heavy Destroyer ESTEEM, 2 Stalwart light frigates, the UNSC Bellerophon and the UNSC Fair Wether, 2 SDV-Class corvettes, the Ardent Prayer and the conceiving Light, and 3 Civilian vessels, the Liberty, the Independence, and the Naomi; where observing the data transmitted from the planet, to say that he had no idea what most of that data mean was an accurate observation, but what he did know was that he had a feeling that this was something big, in a good or bad way he didn't know, but he will be prepared in case the worst happens.

"Shipmaster" Uptac, an Unggoy Petty Officer 3rd Class managing the communications of the ship said, "We have an incoming transmission from the Liberty, do you want me to patch it through?"

"Yes, let's see what the scientists have to say about all this" Orna said.

"Immediately Shipmaster" Uptac said while passing the transmission.

Orna looked at the communications screen, there appeared a female human, she had a round like shape face, long black hair like the void of space, and blue eyes that showed curiosity and knowledge of what its outside in the galaxy, Orna could only identify her as Elena Ramirez thanks to the badge that she had, and he knew that she was the scientist leader of this investigation group, "Shipmaster." Elena said.

"Doctor, I presume that we know what is happening in the surface of the planetoid?" Orna asked.

"Based on the analysis made by the proves and the scans made by your ship, we have been able to determine that M4578S its suffering a magnetic field change, also seismic activity has been detected on the surface, and the velocity of the orbit of the planetoid is decreasing by a factor of 10 for each 30 minutes" Elena explained.

"So you are telling me that a planetoid, that it's supposed to have zero seismic activity, its having multiple one around it? Also how is it possible that its orbit velocity it's decreasing?" Orna asked, he had not much knowledge of astrophysics but he knew that a planetoid was not supposed to have any kind of seismic activity and that any object in space didn't decrease its velocity unless another force was acting upon it.

"Based on the more profound scans made by your ship and the AI aboard the Fair weather we have determinate that something inside M4578S it's the cause of this anomalies" Elena stated while looking at a notepad that she had, "Also based in the quantities of energy detected in M4578S we are estimating that in a few hours M4578S would be destroyed by this massive expulsions of energy." Orna could only wonder what this information could mean to the Alliance, if what the doctor said was true, that probably was, this meant that a potential artifact could be inside the planetoid, but what it was it was any ones guess, "Shipmaster I request permission to take a closer look to M4578S, so we can make more profound scans of the energy, if we can determine what kind of energy it is emitting we could have a more accurate guess at what lies inside M4578S"

Orna considered what the doctor was telling him, if he didn't give her permission, the fleet defending Phoenix could be at a disadvantage if what was inside the planetoid was something dangerous, but if he give the doctor permission to continue her scans they could alert the fleet defending Phoenix in case worst came to worst, yes he knew that he could very well loose part of the investigation group with that decision but he would take precautions to prevent that from happening.

"Permission granted doctor, but at the first sign of trouble pull back immediately, got it?" Orna said with a stern gaze.

"Affirmative shipmaster" Elena said before cutting the connection.

Orna sighted and looked at the bridge, " Officer R'das" he said to his systems Petty officer 3rd class, "I want you to scan the Liberty and the Fair weather once they get close to the planetoid, any change in diagnostics and you are to inform me immediately"

"At once shipmaster" said R'das before turning to his console and do as he was commanded.

"Uptac contact high command and transfer the transmission to my headquarters, they will want to know what's happening here" said Orna.

"Yes shipmaster"

"Commander Nor 'Kros you have the bridge till I return, if something happens inform me at once"

"As you command shipmaster" answered 'Kros.

With his orders given Orna made his way to his headquarters to talk to high command and explain the situation, with some luck and this events would signify something good for the Alliance.

September 5, 2574, 2230 Hours, System Alliance Calendar, Deca-5 system, Stalwart Light FrigateFair Weather, Orbit around planetoid M4578S.

Captain Frederick Stuart, veteran of the Human-Covenant war, hopped that the eggheads aboard the Liberty knew what they were doing. After he received orders from shipmaster Orna to escort the Liberty closer to the planetoid he wondered if he received enough paying to get this close to those expulsions of energy from the planet, that for all he knew that energy could kill him the instant it reached him, it wasn't that he didn't liked the assignment but since this operation started he had a presentment in his gut that said that this energy dilemma was bad news.

Frederick sighted and looked at the tactical screen in the center of the bridge, "Raven how are the scans going?" Frederick asked the AI of the ship Raven, which actually looked like a Raven, 'seriously who names AI's this days?' Frederick thought.

"70% complete captain, we will finish the scans in 2 minutes and 37 seconds the moment I finish speaking." Raven answered.

"Copy, Lieutenant Rogers contact the Liberty" Frederick said to communications, 'let's see what the doctor has too say about the data' he thought.

"Yes Captain" answered Rogers, "Liberty on screen sir."

Frederick looked at the communications screen and he could see Dr. Ramirez and 3 more eggheads checking data on the multiple of holo-screens in the bridge of the Liberty.

"Yes Captain?" the doctor asked.

"Dr. Ramirez report, what are we dealing with here?" he asked.

Elena took a minute to respond, checking data and giving directions to her colleges, then she answered, "Based on the scans captain, we determinate that we are dealing with energy only found on dark matter, also the energy has increased by a factor of 6 since our last scan."

Frederick took a moment to process what he was told then he asked, "Does this energy will affect our systems?"

"Unlikely, while this amount of energy is troubling, our shields should be able to deflect most of it." She answered.

"Most of it? What happens with the rest that penetrates our shields?" Frederick inquired.

"The little energy that is not being deflected its actually fortifying our shields." The doctor answered while Frederick wondered how that was happening, but before he could ask Raven said.

"Captain detecting grand spikes of energy increase signatures inside M4578S, also seismic activity has increased, I suggest that we pull back, at this rate that quantity of energy will destroy M4578S in minutes" Raven sated in a calm voice.

Once Frederick heard that he addressed the doctor, "Doctor Ramirez I want the Liberty back to formation with the rest of the investigation group now." He said with a tone of voice that gave no space for excuses.

"Yes Captain" the doctor said with disappointment in her voice, it wasn't that she wanted to get the crew aboard the Liberty killed, no but this was probably the closest to study this type of energy that she would ever get, she just wished that she would had have more time to study it. She disconnected the transmission to pull back with the rest of the group.

"Raven pull the ship back in formation now" Frederick ordered the AI.

"Yes captain, pulling back now" Raven said

Frederick just watched the planetoid in what he presumed were its last minutes of existence.

September 5, 2574, 2309 Hours, System Alliance Calendar, Deca-5 system, CPV-Class Heavy DestroyerESTEEM, Close to planetoid M4578S.

Once Orna received word of what was happening he cut the transmission with high command and made his way to the bridge more at peace than when he left the bridge. Once he had explained the situation to high command they decided to send the Fast Response Fleet (FRF) Alpha, which consisted of 4 CCS-Class Battlecruisers, 5 UNSC Destroyers, 5 UNSC Halcyon-class light cruisers, 8 SDV-Class heavy corvettes, and 3 UNSC Strident-Class Heavy Frigates, which would be in system in 30 minutes. If the worst happened at least they would be prepared.

When Orna arrived to the bridge he saw that the investigation group was in formation and away of M4578S, but that wasn't what stopped him in his tracks, no the fact that M4578S had disappeared and its place was a fork like structure with a brilliant blue miniaturized star surrounded by 3 rings rotating in different trajectories around it, and what was left of M4578S floating around said structure.

"For the gods, commander what just happened?!" Orna asked totally surprised by what he was seeing.

"Shipmaster apparently that structure destroyed the planetoid after the energy of the object increased" commander 'Kros answered.

"Uptac contact Captain Stuart of the Fair Weather and Doctor Elena of the Liberty at once, I want to know the details of this event" Shipmaster Orna commanded, "Also I want the investigation group in red alert, tell all ships to have weapons ready and shields at full force, send a message to the civilian ships I want them behind the frigates"

"At once shipmaster" Uptac stated, "Shipmaster, Captain Stuart and Dr. Elena are on screen" he announced.

Orna turned to the communications screen and noticed the worried expression of the captain, likely because he, like him, could tell that this situation could turn very dangerous any minute now, he also noticed the exited expression of the doctor, like all scientific minds he had known she surely was fascinated by this artifact just as his people were when they would find Forerunner relics during the Great War, sometimes he asked himself if the Humans and the Sangheili were more similar than different, but that would have to wait he had more important matters at hand right now.

"Captain, Doctor" he grated, "I presume that you are informed of the…interesting developments that happened." They both nodded comprehending immediately of what the shipmaster was talking about. "Doctor can you explain what exactly happened?" he asked.

Elena took some seconds to form an answer then she said, "Shipmaster, Captain, it appears that when the object liberated that enormous spike of energy M4578S couldn't retain the energy any more, making the planetoid collapse in itself. Further readings and analysis of the object, with the help of scans and Raven, we have concluded that the object appears dormant, I suggest that we take a closer look to have cleared readings."

"Shipmaster if I may?" Captain Stuart asked, "It wouldn't be better if we wait for reinforcements in case this situation goes south? I mean the object, designated Tango 1, managed to send a big wave of energy while it was dormant, if what Dr. Ramirez says is correct, then if we accidentally activate it while investigating it we could make this situation a dangerous one for us and the colony, if we wait for reinforcements and the worst happens we could be more prepared to deal with whatever it is going to happen more easily." The captain expressed.

Orna considered both suggestions and while he was curious as to what this object was and what was it that it does, he knew that Captain Stuart's suggestion was more appropriate for the current situation. With that in mind he make his orders.

"Doctor prepare your team to investigate the object you are to be deployed in a Pelican escorted by 2 Banshees in 40 minutes. Captain your Frigate wild be close to the investigation team for extraction in case something happens, the Fast Response Fleet (FRF) Alpha will arrive in 20 minutes." Orna watched as Captain Stuart relaxed a bit after hearing that reinforcements were in route to the system before acknowledging his orders and disconnecting the line with the Doctor not far behind. 'At least we will be prepared in case something goes wrong' he thought.

September 5, 2574, 2334 Hours, System Alliance Calendar, In Route to Deca-5 system, CCS-Class BattlecruiserPurity of Spirit, 5 minutes to exit Slipspace.

Fleet master Qunu watched the report of what was happening in the Deca-5 system, to say that he was worried about the meaning of this was an understatement, he knew that this discovery would change the way the System Alliance viewed the rest of the galaxy, but he also knew that if this situation went in a positive way it would open more possibilities to the Alliance, but if it went south then he didn't want to imagine the repercussions of this. Qunu had fought in the final years of the Great War and despite that his people are a warrior race he didn't like to fight another war unless it was for the right reasons, after all for all that he knew this device, designated Tango 1, could be a trap from the Loyalist or from another race that wanted to exterminate them.

"Fleet master we are exiting slipspace" Announced Tala 'Lira the systems Liutenant taking him out of his thoughts.

"Understand, navigation show me the status of the fleets in the system" Qunu commanded.

"Yes Fleet master" the navigations officer answered while showing in the tactical display the status of the fleets.

After analyzing the situation Qunu distributed his fleet to offer maximum protection to the colony and the investigation group while this situation was resolved. He then addressed his communications officer.

"Crewman Robert transmit the following orders to the fleet and the Defense Fleet of Phoenix; I want the UNSC Destroyers Armageddon's Edge and Iroquois, and also the SDC-class corvettes Solstice, Redeemer, Lightning strike, and Adamant Prayer to accompany my ship to the location of the investigation group, the rest of the fleet is to maintain position at sector 6B" Qunu ordered.

"Yes Sir." Robert answered while transmitting the new orders.

"Crewman Robert contact the CPV-Class Heavy Destroyer ESTEEM" Qunu ordered.

"Acknowledged" Robert replied, "ESTEEM on screen Fleet master"

Qunu turned to the screen and saw shipmaster Orna's controlled expression on screen.

"Fleet master." Orna replied.

"Shipmaster Orna I trust everything is under control?" he asked

"Affirmative Fleet master" Orna answered.

"Good, what's the situation shipmaster?"

"After reading heavy sparks of energy on the planetoid we pulled back, once we made it back to a safe distance we observed how M4578S imploded in itself revealing an artifact designated Tango 1, I give my authorization to deploy a science team to investigate further the artifact in a Pelican drop ship escorted by 2 Banshees and the frigate Fair Weather, they are to be deployed in 5 minutes Fleet master." Orna replied.

"Good work Shipmaster continue the operation will be on standby in case something happens, Fleet master out" Qunu cut the connection and observed the situation unfold in front of him.

September 5, 2574, 2344 Hours, System Alliance Calendar, Deca-5 system, Pelican Drop ShipDelta-309, In Route to Tango 1 Artifact.

Doctor Elena Ramirez was exited, this was going to be the one of the biggest discovers that the Alliance would make, and she was sure of it, after all how many time did you discovered and artifact that worked using dark matter?

"Doctor we are in range to scan the artifact, do you want me to proceed?" asked the pilot.

"Affirmative commence scans" she commanded

"Copy Doctor commencing scans now" replied the pilot.

"Wallace I want you to check the spectrum analysis of the object, Davis look for any kind of transmissions or signals from the artifact" commanded Elena.

"Yes ma'am" replied Wallace and Davis.

"Doctor, spectrum analysis report that Tango one is having a constant fluid of energy" informed Wallace.

"Understood keep scanning, Davis report?" Elena replied.

"Doctor I'm receiving some kind of message covered in static from the artifact, I can't clear it, do you want me to answer?" asked Davis.

"Negative let's get closer, let's see if you can clear it that way if not answer to the message."

"Copy Doctor" replied Davis

"Pilot get closer to the artifact to get better readings" Elena ordered.

"Copy that ma'am" the pilot answered, "getting closer to Tango 1"

Once the Pelican started moving Elena could field the gravitational pull that the artifact had on the drop ship.

"Davis can you clear that message?" she asked.

"Negative, I'm sending a signal right now" Davis complied while sending the signal.

"Doctor? What's happening? Tango 1 is showing increase of activity, it is pulling us to it, retiring from Tango 1 at once over." The pilot informed.

Elena could indeed feel the pull of the artifact and she couldn't agree more with the pilot that it was time to go back but apparently the artifact had other ideas.

"Here Pelican Delta-309, we are getting pulled towards artifact designed Tango 1 and we can't pull back, repeat we are getting pulled towards artifact designed Tango 1 and we can't pull back, I request an extraction over."

"Here Frigate Fair Weather coming to extract pelican standby we are coming ETA 90 seconds over"

"Copy, over" the pilot answered while trying to pull the Pelican away from the artifact but it was in vain because 30 seconds after the message the artifact let loose a type of energy that evolved the Pelican, then in a flash of light it was sent at a bigger speed that the speed of light towards the unknown.

September 5, 2574, 2400 Hours, System Alliance Calendar, Unknown system, Pelican Drop ShipDelta-309.

"System are fried, it appears that artifact Tango 1 killed all the system except vital support Doctor" The pilot informed to Doctor Elena.

"Understood pilot let's hope that the Alliance send someone for us." Elena said while trying to get the systems online with the help of the other 2 scientist.

September 5, 2574, 2400 Hours, System Alliance Calendar, Deca-5 system, CCS-Class BattlecruiserPurity of Spirit, Observing Tango 1 Artifact.

When Fleet master Qunu watched the Drop ship get fired like a MAC cannon round across the fabric of space after getting close to Tango 1, he didn't know what to think, that's why he contacted the CPV-Class Heavy Destroyer ESTEEM and the Stalwart Light Frigate Fair Weather to assert the situation at hand.

"Captain Stuart what can your construct tell us about this incident?" Qunu asked.

"Fleet master, it appears that Tango 1 is a transportation device of some sort according to the readings that Raven got once the Pelican got… shot into space" replied Stuart.

"Fleet master if that is the case I offer my ship to go after the pelican and rescue them." Offered Orna.

"Noted shipmaster, we aren't taking any chances here, your ship as Captain Stuart's ship, the UNSC Destroyers Armageddon's Edge and Iroquois, and my ship will go through the artifact and extract the Pelican, we can't lose the lives of those brave souls that risked their lives for the understanding of this artifact." Both the Captain and the Shipmaster nodded, then they closed the line to prepare their ships.

"Crewman Rogers inform the UNSC Destroyers Armageddon's Edge and Iroquois that they are to accompany us to go through the artifact with the Fair Weather and the Esteem" Qunu ordered.

"Yes sir" Replied Rogers.

'Let's see what await us in the other side of this artifact', thought Qunu before their ships were evolved in the brilliant light and shot towards the fabric of space.

September 5, 2574, 2410 Hours, System Alliance Calendar, Unknown system, CCS-Class BattlecruiserPurity of Spirit.

Once the group of 5 ships made it through the artifact Fleet master Qunu turned to the bridge, "Lieutenant 'Lira Fleet report"

"Fleet master all ships report operational, the Destroyers report reactors at 137% of capacity and shields at 78%, the Fair Weather reports shields at 50% and the reactor at 112%, and the Esteem reports shields at 86% and reactor at 120% our ship has shields at 90% and the reactor is at 145% sir." Replied 'Lira, "Sir all ships report all systems returning to normal"

"Understood ensign start scan of the system, Robert inform the Fair Weather to locate the Pelican, also inform the Destroyers to prepare weapons in case we found hostiles, put all ships in red alert" Qunu ordered.

"At once sir" replied Robert, "Sir the Fair Weather reports that it found the pelican, they are extracting it right now." Robert informed.

"Fleet Master" 'Lira announced, "Scan of system complete, I detect another artifact identical to Tango 1, also 15 unknown contacts are around the second planet closest to the star in the system, and 10 unknown contacts approaching to our position, from the looks of it they appear to be 6 Corvettes, 3 Light Frigates, and 1 Heavy Frigate to our standards sir." 'Lira informed.

Qunu could only hope that this situation did not extend to a conflict between this unknowns and the Alliance.

A/N: So here we go the first chapter of the story, I'm sorry to inform that I don't know when I'll be able to post the nest chapter but I'll do it as sun as I can I promise, also please review and tell me what you think, give suggestions and ideas for this story I'll considerate each one of them and I'll see what can I do to include them, and also I'm in the need of various OCs specially alien ones, please specify the next for the OC: Species, Name, Rank (if military), Branch in the military (if military), abilities (if any), specializations, I would appreciate that. Thanks for reading and until the next chapter.
