Okay so the previous chapter wasn't long by your standards so please bare with me on this I can't write long and my grammar sucks that's a fact couple with my English.

So now in this chapter we'll be focusing on the history of the citadel and the continues changes that our MC is going to do and some trolling here and there. Also I'd like to say thank you for the reviews it helps.

Also id like you guys to comment on some of your Ocs whether they are purifiers or the council races and cause I suck at creating names…

I would also say this, the story ain't your typical self insert and there are surprises up ahead not just changes on the course of history. Also I'd like to thank Mr. guest on his review regarding this, I will not touch the events of ME by much it's more like a ghost coming out of nowhere and scaring the shit out of people just for laughs and don't worry about the important parts of Mass Effect cause I won't touch it but the Catalyst stays with Arun till he deems to return it to Citadel.

So with that out of the way hit Arun!

ARUN: Amano does not own Mass Effect, Starcraft and the Sentinels but he does own the Oc lives… may Emperor help us.

CHAPTER 4: TIMELINE WITH A FEW SCREWS LOOSE

GENERAL POV

Spending years near the Citadel, Arun did some studying on the old races that the Reapers harvested in the previous cycles and the only answer he gets is "Harvest… really can't these guys do anything other than harvest?" as he looks into the terminal incredulously

"These guys are so simple minded I can't help but question the mentality of the leviathans regarding their so called problem" the only thing was able to learn were knowledge and battle tactics left by the protheans to understand the species. Not much was left by the Reapers so he had to make do with what he had.

He did discover some of their planets with data from the intelligence on the Relay activities and he mapped the frequently used ones at the time. And since his memory on most of the events weren't good he had to make do with what he'd known on some of Shepards missions regarding the Reapers and only ilos came to mind with the Prothean Vi 'Vigil'. And regarding the Vi he would just leave it as it is to let the events flow naturally, also to avoid some unnecessary events that might occur with his tampering.

Arun did some 'testing' within the following years on the Catalyst, and he found some very interesting finds. It was mostly bio data on all of the deceased races that the Reapers have Harvest since their creation. He did find it intriguing to revive them or make them purifier personalities, but that would take the fun out of everything if he did that. He did however plan to revive them after the events of Mass Effect 3 or somewhere in the Andromeda timeline. He also found something interesting on the intelligence code, that being a learning program. It seems that when the leviathans created the Ai they were just too lazy to fix the problem and had it unlimited access on what to do to find a solution, and with its answer found it sought to do what it was intended. So all in all the Ai was just a simple minded construct, not too complex as Arun thought.

"Will you let go of me, Purifier" and within Arun's Core Matrixes lie the Ai, constantly bugging him for release

"No" and within those years he learned to ignore or tolerant the constant annoyance of the Ai.

It was a bundle of chaotic data at first within his body, always trashing and sending junk codes and self made viruses. But it wasn't enough to break the firewall within his advanced network of codes added to the Purifiers network, the Ai had no chance of escaping his matrix. But as time passed it knew it wouldn't escape so it did the best thing to release its stress 'Annoying it's host to oblivion' and constantly questioning about the makers of the Purifiers and where they originated.

To its satisfaction and annoyance, Arun would reply to it in cryptic and short versions of what it asks and mostly satisfy its curiosity towards the Purifiers not related to their making. Right now Arun was busying himself with studying some of the Reapers Arsenal, he had obtained within the Ai. He admits that he didn't paid too much attention on them other than shoot it with a big gun and hope it dies, back when he was playing ME. So now he is visibly annoyed with the Ai's constant pleas.

"For how long will you keep me locked up?" It asked in monotone, its favorite default voice setting just to piss the other off.

"That is for me to know, and WILL YOU SHUT UP!" his visor lights up with his mood being a bit irritated.

"Not until you give me more space it's cramped in here"

"Do you want me to shut you up" he says as he reaches to the side of his left arm, fingers hovering over some holographic buttons.

"…"

And with that the Ai shuts up not wanting to anger its host, cause within the time of its confinement its host would usually send a stream of data to corrupt most of its code. It can easily repair it, but it hurts. In terms of being a synthetic, the data is like a paralytic venom with a lot of pins sticking within the area corrupted. And its host would use that when it gets a bit annoying.

"Finally…" Arun grumbles as he continues reading the data within the terminal.

During Aruns first ten days in the Mass Effect universe he had sent observers to the Council races homeworlds, to do some studying on their tactics and psychology to better understand them for future talks. And from what he observed the Asari were already doing their wide spread colonization and exploration in their area and closing in on Citadel and it was estimated they would arrive here in a few hours, the Salarians in the mean time were… back stabbing each other at every turn and furthering their own technology against rival political figures and their so called 'intelligent services' or rather named League of One almost found an observer when it got to close to a motion detector. The Turians on the other hand were to put in simple terms showing their big guns and their colonies starting to get a bit rowdy it, would be 60 years till their Unification War starts.

Their histories were quite interesting to read and watch in the eyes of the observers in their system and cause Arun also didn't care to look up much on their history, only the major parts that seemed interesting when he was still human other than seeing if they could 'interbreed'… never mind that. He also did some language decoding on the Prothean alphabet and that of other races in hopes that the Theatric he has planned will blow the Asaris minds when they arrive.

While Cybros stationed itself near the Citadel waiting for the Asaris arrival, back at Auir most of the system was filled with activity. Since Arun left he made some plans regarding the system, that being it preparing itself for the so called first contact scenario with the humans and Turians. Which is a thousand years from now.

One of them is a bigger version of the mothership. From its 3km length and width and 1km height, it will be increased to a 8long and wide ship with a 4km height. Its purpose being the flag ship of Arun to showcase their technological superiority and to keep humans from advancing into space without properly defending themselves and for Crushing Desolas forces when he enters the system.

While the construction of the mothership was going, the planet itself was fully settled. With most parts of the major continents sported cities of gold and Purifier bases stationed near them for protection. The orbital stations surrounding the planet have upgraded themselves since Cybros left, with new armaments such as interceptors stored in certain hangers to fend off ships at close range to upgraded shielding that could take on a barrage of medium sized asteroids, coupled with some Phase Disruptor cannons at the sides. It was also necessary to add some additional armor to stations for added defense and give the stations mobility like Cybros. There are a total of ten stations surrounding the planet coupled with the ten motherships and their escorts within the system.

The moon of Aiur now named Luna, was turned into a mini garden world for added space to the growing empire and its sole purpose as a communication array with Psi spires littered all over the moon. The moon now houses 30,000,000 Ai personnel most of them being high templar to broadcast the Psi network of the Purifiers. There are some research stations within the moon filled with Khalai engineers and Sentinels for the Scientific division of the Empire. Their main goal is to find different types of resources that could potentially aid the Purifiers in the long run, it was Aruns orders to find alternative fuel so that they won't be over reliant on Solarite and to broaden the technology of the Protoss Empire while he was gone.

There were some scientific progress in their works, like the fusion between the Probe and the Energizer for mobile base building and for rushing opponents near the sector. There were also notable changes with the Colossi, their Thermal Lances fire more power and that they are equipt with a Phase disruptor at their heads to let them target air units sadly they are still weak when they are surrounded. Some of the weaponry where upgraded to fire faster than before like those of the canons of the Immortal and some were added more fire power like the Stalker.

The Theta system were the Purifiers reside is heavily defended with motherships and their escorts patrolling the area for any dangers, mobile orbital stations near the planet, to the planets Photon and Plasma Cannons. The Relays in the area were positioned to desired chokepoints for better coordination of the fleets in the area to the stations weapon range.

And within those years the military section where beefing up their Navy for the coming events within the following years ahead.

SOMEWHERE IN SPACE

A group of Asari explorers were assigned a task to find the famous Citadel the Protheans spoke about in the beacon. It was a daunting task and it seemed that they would never find it with so many relays in the area of space. Until they finally found an active relay that seemed to lead into a series of other activated ones, and with that they continue following the route laid upon them by the Reapers towards the Citadel.

Not knowing they were being watched by invisible eyes of the observers.

The Asari were using the Destiny Ascension, their greatest ship and symbol of their technological superiority from the other Council races. As it glides beautifully at space it finally reached the Relay to the Citadel, and with no hesitation it entered. The Rings of the Relay spin and with it the bluish energy engulfed the whole ship transporting it to the other side...

CITADEL

With one of the Relays showing a massive amount of energy spike, Arun stopped his studying on the Reapers and looked to the viewing deck seeing the Asaris arrival into the system from the celestial array. Grinning he went to order his men to power up Cybros and prepare a file to be sent to the blue bitches when they're done.

As Cybros powered up its systems, the Asari marveled as they gaze towards the Citadel for the first time in their lives. And with that they traveled closer towards the station, too focused on the Citadel they weren't able to notice the Purifiers within the system, nearing it they were engrossed by the architects beauty and size.

"By the Goddess! We finally found it!" one of the younger Asari crewmen said as she gazed upon the station with stars in her eyes.

"Agreed, we are the first of our kind to discover it. It was a blessing we found that active Relay" another one piped up.

"The Goddess must have answered our prayers!" a fellow devotee to the goddess exclaimed as she put her hands together.

As the Asari were celebrating within the Destiny Ascension, one of the crewmembers manning the visual sensors of the ship noticed a signal emitting 50,000 km behind the Citadel. Alarmed she turned to the Matriarch Fal'lita Edodri who led the Asari exploration to the Citadel, and reported her finding to her.

"Matriarch! There is something behind the Citadel, it is giving of strange Solar readings!" she exclaimed pointing to the origin of the signal on the visual sensor noticing a white structure with golden glows rising above the Citadel.

"What?!" Matriarch Fal'lita looked onto screen noticing it as well. As the structure slowly rises, she noted the designs of the mysterious structure. It was T shaped with three massive Appendages connected to its Oval head with golden glowing lines that encircled some parts of the station, at the center of its head where building like structures that glowed once in a while. The neck till its tip on the other hand resembled that of a syringe.

"By the Goddess! Its 1/2 the size of the citadel" the crewman in charge of the sensor exclaimed as the structure positioned itself on top of the Citadel.

As the structure came on top, the three arms around its side were spinning, Fal'lita was immersed watching the structure until her aide notified her of an incoming signal within the citadel.

"Matriarch! There seems to be a Prothean broadcast within the Citadel" Fal'lita's aide exclaimed when she noticed the signal being more frequent and distress, as the White stations readings were excluding an high energy output at the tip.

"There seems to be a high output of solar energy coming off from the structure, Matriarch! It seems to be firing towards the citadel!" the aide went frantic as the energy readings were similar to that of a solar flare.

"Helm, connect it to the Destiny Ascention and get us far away from the white one!" Fal'lita exclaimed as the crew within the dreadnought got to work on their assigned stations, activating the Eezero drive core the ship jumped 30,000 km away from the Citadel.

Within Cybros, Arun mused as he watched the Asari moved a couple of kilometers away from the two stations. His plan was simple broadcast a signal in perfect Prothean with the main theme being 'mercy' and using Cybros to show a scene of them wiping out the last of the Protheans within the Citadel.

Within those years Arun had the Prothean bio template that he got from the Catalys,t and used it to create bodies for his grand theatric though he did make them asleep to avoid any escapees. He aims to do something similar to that of the Ur-Didact but with leaving some remains in the form of bones and dust within the Citadel. He had to modify the Purifier Beam to not damage the Citadel and to only destroy the Protheans clones within. And with that he activates Cybros modified beam to kill the Protheans.

From the Asaris point of view within the Destiny Ascension, they were shocked to say the least from what they heard from the broadcast. It was a constant plea for their lives in perfect Prothean over and over again, some of the younger maidens within voiced that those were Protheans themselves sending the message. But those older didn't care about whether or not those where the Protheans, all they see was a weapon of mass destruction used on the famed Citadel.

But they all were baffled in the end as to why the Citadel still stood, from their readings it was a direct energy weapon used on the station.

"What? How can the citadel stand after such an attack?" The Matriarch questioned as she gazed upon the Massive station, with no signs of damage what so ever.

"Matriarch, the signals within the Citadel has stopped!" a maiden exclaimed as she got no further readings from within.

"The White one is activating again!" the sensor crewman stated as the readings of the White station powered up once more.

"Micro jump us away again" the Matriarch said with fear as she thought the station will use an even more powerful attack "Get us awa-" she said before she was cut off by one the visual crewman.

"Mam, the station just disappeared!"

"What?"

"It's just as I said… it just disappeared" the visual crewman said as she found no visual and energy readings within the area it was last seen.

"What was all that?" one of the younger crewmembers said as they all try to decipher what happened a minute ago.

"I don't know… helm move us into the Citadel! Let's check if there was anyone alive in there"

When the Asari arrived to the massive station they were surprised to find dead bodies of the inhabitants, they all share one thing in common and that is their organic parts were incinerated. What was only left were bones and dust thought the complex. But what surprised them were those that survived the blast the 'Keepers', it seemed that whatever that weapon was it only targeted the inhabitants and left the rest intact and explained why the Citadel wasn't damaged.

As they explored within they uncovered some of the files that Arun found within the station regarding the Protheans, most of them were about civilian technology and biotic implants but those regarding the Reapers where discarded for it only said 'Reaper and the other Harvest', they only assume it as something in an agricultural sector with the words themselves being vague. But what they found most alarming were messages that seemed to be left by the inhabitants about the white station, they were vast from their failure in some tests to unworthy to the so called gods named Protoss.

And with the event that was witnessed that day, the Asari historians of the future would always look back on their history of their arrival on the Citadel not knowing who or what attacked the station, but only knowing that they were possibly the ones to wipe out the Prothean Empire. It was also kept a secret to Aruns delight about the events that transpired that day, to the other races of the galaxy they didn't know for the Asari kept it a secret hoping that if whoever these Protoss where to came back they would try to negotiate with them.

And with that a minor change within the Asari happened for they were preparing for the Protoss arrival believing them to be a higher race that deemed the Protheans as a failure. It was in some messages that Arun left within the Citadel that changed most of the Asaris view of the Protheans

'Species code 0146-Prothean were a waste of our time, they failed the test we laid out to them and breaking one of our sacred laws the Daeh'ul. They were an arrogant species that turned to their watchers believing themselves as the pinnacle of other races. And with the order of the conclave it was deemed to Purify the race as to stop its blight'

The Asari were baffled as to what kind of law the Daeh'ul was, it seemed too holy that the Protoss deemed the Protheans as a threat to some kind of order. Whatever it is they were watching before the Protheans even learn learned to make fire, this information and anything related to the Protoss and Protheans were kept a top secret from the rest of the population and only the Asari Matriarch Council knew of it. It was deemed as a Black file same with the Prothean beacon within the statue of Athame.

So with that the history of the Citadel Era Begins

13,000 BCE

The turians of Palaven begin to develop civilization around this time.

6000 BCE

Seeking to escape the imminent explosion of their sun, an alien race constructs an AI-managed starship equipped with supercomputers containing a virtual world, into which some one billion of the aliens transfer their consciousnesses. The starship begins a journey throughout the galaxy which lasts for the next 8,000 years.

1900 BCE

Tuchanka, the krogan homeworld, enters the nuclear age. In a global conflict, weapons of mass destruction are released, triggering a nuclear winter. In the resulting devastation, krogan society devolves into a collection of warring clans.

1800 BCE

A supernova propels the Mu Relay, the only point of access to the remote Pangaea Expanse, out of position. Concealed somewhere in the dense nebula formed by the supernova, the relay's position is effectively lost for centuries. Later, the rachni rediscover the relay.

And during this time Arun was sent to the Mass Effect Universe

580 BCE

After developing faster-than-light spacefaring capabilities based upon Prothean technology, the Asari begin to explore the mass relay network, and eventually discover the huge Citadel space station and the Purifier station at a hub of many mass relays.

Many searches were conducted to find the enigmatic station, but it proved fruitless. It was also noted that whatever energy used by the station wasn't Eezero but some form of Solar energy. Many Asari scientist where tasked to find substance, they did find it but the way in collecting it was deemed to damgerous for the energy was the sun itself and was too unstable for use.

520 BCE

The salarians discover the Citadel and open diplomatic relations with the Asari. Arun kept watch on the two races aboard the Citadel with his Observers within the srructure.

500 BCE

Founding of the Citadel Council

The Citadel Council is formed. The asari and salarians together colonize the Citadel and establish it as a center of the galactic community, led by the Council. This year is also known as 0 GS, the beginning of the Galactic Standard (GS) timeline.

As a gesture of openness with their new asari allies, the Salarian Union opens the records of the League of One. Under threat, the League responds by assassinating every member of the Union's inner cabinet; Special Tasks Group operatives then hunt down and eliminate the League.

First contact is made with the volus. Eventually, the Citadel Council commissions the volus to draw up the Unified Banking Act, which establishes a standard galactic currency known as the credit and links all galactic economies.

The turian Unification War occurs. The increasingly isolated and xenophobic colonies on the frontiers of turian space go to war with each other. After years of fighting, the Turian Hierarchy sweeps in and pacifies the remaining factions. Animosity between turian colonies continues for decades.

The Council grants the volus the honor of being the first non-Council species with an embassy at the Citadel, rather than a Council seat.

First contact is made with the batarians. They are granted an embassy a century later.

The asari discover the elcor home system and help the elcor locate and activate their nearest mass relay. "Within one elcor lifetime" they establish a regular trade route to the Citadel and are granted an embassy.

First contact is made with the hanar and the quarians. Both races are later granted embassies.

320 BCE

The three worlds around Aiur have been terraformed and named Shakuras, Endion and Haven in order. Each planet contains each faction of the Protoss respectively. Aiur being the Capital planet, Shakuras for the dark templar templates, Endion for the mechanical and scientific division, and Haven as the agricultural sector.

Council Era - War and Rebellion (1 CE - 900 CE)

1 CE

Around 1 CE, salarian explorers opened a mass relay to a previously-unknown system and encountered the rachni, who promptly captured them. The rachni used extensive research on element zero gathered from Kashshaptu to reverse-engineer the FTL drives of the explorers' starships. They proceeded to construct FTL vessels of their own and rapidly expanded into the galaxy, ushering in the Rachni Wars.

Attempts by the Citadel races to negotiate were futile, as it was impossible to make contact with the hive queens that guided the race from beneath the inhospitable surface of their homeworld. It was assumed that the rachni were irredeemably hostile and could only be stopped through warfare, but the rachni had the upper hand and overwhelmed defenses with their sheer numbers.

The Rachni Wars begins.

With news and alerts about a hostile race spread cross Citadel space, an all out war was declared by the Council deeming the race a threat to the peace of the public. With the observers stationed within and out of the Citadel, Arun was able to get a glimpse of the panic and chaos that some of the citizens were displaying.

While the Council was concerned dealing of the upcoming threat and trying to evacuate their colonies at the front of the war, with the Rachni decimating all ground opposition. Arun was busy preparing his flagship named 'Tears of Serenity' the upgraded mothership that he planned a few years back. His goal was to protect and safely escort civilians to safe zones so that the Council will 'owe' him for his services and to instill fear and admiration to the general public.

CODEX ENTRY/PURIFIER

Tears of Serenity- a Purifier mothership, it was built as Aruns flagship to show superiority against those who defy the Protoss Empire. Unlike the regular motherships it size was doubled to 8km long and wide with a height of 4km, its weapons were upgraded to take on fleets of ships and its support armaments capable of stalling the enemy opposition. When surrounded it can warp out of the area and leave a blackhole to destroy those within the area it once was.

Leaving, Arun set out to Citadel space to begin the operation 'Safe Haven'.

Okay now hopefully that was long for you guys and I would like to say thanks for the reviews you've given me, it means a lot. Also I would like to shout out to my favorite girl cousin who helped me made this fic longer.
