Act 1: Unwanted Attention

January/11/2662

Milky Way / Hades Gamma Cluster / Antaeus System

Near Planet Hunidor

Onboard the Turian Dreadnought Pride of Palaven.

Captain Mankanaze Modon stared trough the viewport. While it provided an excellent view of the orbiting gas giant, the Captain was too preoccupied to notice it. His mind was racing with the questions that started after reading the report he received from his ships long range sensors.

Less than a minute ago a small one man craft entered in this system. It didn't resemble any known design and went beck almost as soon as it came. While a scout frigate is currently scanning the relay to know where the ship came from, all the indication so far hints a first contact scenario. And the last first contact scenario is anything to go by….

"Captain, you look worried." Turning back, he saw General Desolas Arterius, his superior officer and commander of the entire combined forces.

"Well sir, it looks like we have found a new civilization." After delivering as sharp salute, Mankanaze replied.

Nodding in reply, General replied with a wide smile, "Sure looks like it, isn't it wonderful?"

The veteran Captain rubbed his neck in discomfort, "Well sir our encounter with the Rachni was anything but wonderful". He replied.

"The Rachni were an extremely violent race and had clearly been in space for a century at least, this race however has clearly only begin to explore the stars and is still quite primitive." Desolas said with firm confidence.

"Sir, with all due respect we have no idea of knowing that-" Mankanaze was abruptly cut off by Desolas.

"Calm down Captain," Desolas said offhandedly. "Look at that ships ezzo emissions, it barely has any, and look at it size, do you think an advanced civilization would use a ship that small to explore the galaxy? They've obviously only just begun to explore the stars!"

"But sir…" Mankanaze again tried to voice his opinion but once again he was dismissed by Desolas.

"You're worrying too much Captain," Desolas dismissed the concerns of his second-in-command. "They are obviously a very reckless and primitive species."

"Reckless, sir?" Mankanaze was unsure what his superior officer meant by that.

"They violated a direct Citadel law by activating the Mass Relay, and we are required by that law to police them," Desolas said. Mankanaze once again opened his mouth but Desolas's finishing words made him silent.

"A reckless species like this must be put under the control of the Hierarchy to ensure the safety of the galaxy". Desolas declared.

'Oh ,so that what it's about!' Mankanaze though. 'He is not interested in enforcing the law, not exactly, he's far more interested in capturing the race. An action like that would make him famous throughout the Hierarchy.'

'Not that it's a bad thing' Mankanaze again though. He too is going to share the credit and integration of a new species has its advantages. 'Besides, they did violate the Citadel law, and that calls for a response.'

"How many ships do you want to send General?" steeling himself, Mankanaze asked.

"The entire fleet, Captain." Desolas replied flatly.

"The entire fleet, sir?" Mankanaze was clearly surprised. "But sir if it is a primitive civilization we don't need to… "

"Intimidation is a very effective weapon against lesser races, Captain." Desolas said in a condescending tone. "Besides, the entire fleet is here for training, the policing and integration of a primitive species would be a valuable experience for them."

"As you wish sir." Mankanaze decided to put an end to the conversation as the General clearly made up his mind.

"Massage from the from the scout frigate Captain" A young voice came through the comm. They have confirmed that the ship is in fact from uncharted space and have the coordinates. They are now awaiting orders.

"Tell them to standby. And put the fleet on alert." Mankanaze replied.

"Understood Captain." With that reply, the comm went silent.

"Well Captain, shall we proceed?" Desolas said with a smile that likely won't disappear anytime soon.

Nodding, Mankanaze started heading towards the bridge. He has to address the crew about this while Desolas gets permission from the High command. And Mankanaze knows that he won't be denied.

Act 2: Spartan Room service

January/11/2662

Milky Way/Minos Wasteland/ Caestus system

Near planet Temerarus

Onboard the Batarian slavers frigate Torment.

Off all the nine persons that stood in front of the ships, most even didn't had the chance to call their personal gods before being torn into shreds by a hail of 7.62x51mm bullets form Chief's AIE-486H Heavy Machine Gun. The other six that were standing throughout the hanger didn't had the chance to be surprised as slugs form the roof turrets turned them into Swiss cheese before they could be sure what they are watching.

"Well this is a nice start," Cortana commented as Chief stepped off the shuttle. "Only nine remains. Who said elements of surprise is no longer decisive?"

"No one." Chief gave a short reply and asked, "What kind of obstacle it there between us and the Bridge?"

"Nothing serious, just some small defense turrets and…" Cortana was interrupted by a series of noise.

Suddenly three crates in the cargo bay begun to unpack. Within seconds, they grew legs, a pair of arms which contained an arsenal of weapons and a large round head with a pair of vertical red "Eye" in the middle.

"…Those." Cortana finished her sentence.

Dropping the heavy weapon, Chief quickly dived for cover behind a nearby crate. The heavy turrets immediately opened fire but rocket fire from the giant mechs simply tore them to shreds.

"Cortana a little help?" Chief said as the mechs begun to close in his position.

"Hold on" Cortana said as she quickly begun to surf though the Omi-tool database. "Those are Hahne-Kedar YMIR Mech, factory designation Model 34-A, but more commonly called a Heavy Mech. Heavily armed with twin automatic mass accelerator cannons concealed in the right arm and a rocket launcher in the left and has heavy armor and shield to protect itself. However, it is slow and cumbersome. The head is a weak spot but you have to take down its shields and armor reinforcement that protects it first. Try to stick to cove and fire suppressive shots…"

Before Cortana could finish, Chief bolted out of cover and charged straight for the nearby mech. The giant killing machine turned to face him but Chief jumped as soon the mech raised it weapons. Propelling himself in the air, Chief primed and shoved a plasma grenade in the mech's head. Carrying on the momentum he jolted towards another mech, and took cover behind him. The third mech immediately tracked the movement and fired a rocket toward him which struck home on the mech that was front of Chief. Chief quickly pulled out his pair of M6G that he swapped for the Needlers from the shuttle and fired six shot on the now unprotected head of the mech. Then he dived for his discarded Machine Gun. As soon as he picked it up, both of the mech violently exploded.

Aiming it towards the lone mech that was recovering for the explosion of his brethrens, Chief opened fire. The bullets shattered what remained of the kinetic barrier and punched trough armor like they were wet tissue paper. Within seconds the lifeless hulk of the mech slammed to the ground and exploded.

"…That works too." Cortana said in a slightly amused voice.

"What's next" Chief said as he dropped the weapon and picked up a M45 Tactical Shotgun form the shuttle.

"Well all of them have likely taken position in the bridge, " Cortana said, but Apparently they have about 30 LOKI Mechs and some defense drone. They are going to slow us down a bit but I don't think…CHIEF SHOOT THAT RED BOX!" Cortana suddenly screamed and marked a red circuit box in John's HUD .

Without asking question, Chief quickly pulled one of his M6G and fired multiple shot as the box. The box let out a stream of sparks as it got hit.

"Phew. They were going to disable the force field," Cortana said with relief. "Couple more seconds and they would've vent us to space." Recovering, Cortana came back on topic. "Chief pack some extra frag grenades, LOKI's find strength in numbers and are slow moving, frags will do wonder in close combat."

Nodding, Chief discarded half of his Plasma grenades and replaced them with frags.

"This way chief." Cortana said as she marked a door.

Raising his shotgun. Chief carefully entered the narrow corridor. Cortana sealed the door behind to make sure no one will have access to the hanger bay.

Act 3: Exploration in force

January/11/2662

Milky Way / Orion Arm / Exodus Cluster / Asguard System

Near Asteroid X57

Onboard the ITSS Prometheus.

Commander Katyusha was standing in front of the holographic table. In front of her is the holograph of Captain Ali Bokor, Commander of the survey ship Pathfinder. A well aged and veteran officer, he has a well built body the and really bright blue eyes. In besides him is another holograph of a much younger and well looking blond woman, wearing a white lab coat and holding a pad in her left hand. She is Professor Natasha Petrova, Pathfinder's Chief science officer and her elder sister .For the last 30 minutes, they and Katyusha spoke nothing but the incident and relay and Katyusha's mind is still busy with deciphering half the technical terms her sister so far babbled out. She can't help but wonder if her sister is deliberately using those terms as she haven't contacted her for six months. And that's more than enough to piss her sister off.

"Well Commander, I will return to my duties I'm sure you and Professor Petrova have a lot to catch up." Captain Bokor said to Katyusha and disappeared from the table. She can't help but notice the relief in Captains face just before his face disappeared. She couldn't blame him, as she too would love get away from this nightmare of a briefing.

"Shall we proceed, Commander?" While Natasha's voice contained a calm professional tone, the coldness in her green eye's told Katyusha she's far from being clam.

"Oh come on Sis! How much more you're planning to torture me?" Katyusha simply had enough of her sister's technobabble rampage.

"Six hours, sir." Natasha's answer came with a sinister grin.

"Look Sis, I'm sorry all right?" Katyusha voice sounded as tired as it sounded desperate. "It was a classified raid, I was no allowed to tell anyone about it, not even to you."

"You could inform me that you're going under, sir." Natasha's voice while slightly soften, was still emotionless for the most part.

"I will do that next time. Now please forgive me, Pleeeese?" Katyusha expressed her apology with an expression that is commonly described as ''Puppy eyes".

"Oh, for God's sake Katyusha drop that look. " Natasha failed to keep her professional appearance anymore as smile busted out of her face. "Mother was right, you can make yourself look as cute as a polar bear cub when apologizing."

"There is a reason why I was rarely grounded." Katyusha replied with a smile of her own.

"Anyway how it is with you and Boris? Have you two gone on a date yet?" The sudden question for her elder sister put Katyusha off balance, literally.

"Boris? What is it with him an me?" Despite her best attempt to look innocent, the blood gathered in her cheeks showed her true emotion.

"Oh come on Katyusha, don't you think I don't know what trouble you went through to have him assigned as your first officer? Or how you ALWAYS checking him out while he is looking the other way? " Katyusha can't remember when the last time she saw her sister was smiling so widely.

Katyusha remained silent. But the increase of blood in her cheeks replied for her.

"So how far you two went?" Natasha smile is a wide as ever.

"Well…" Katyusha grasped for appropriate words but unfortunately couldn't find any.

Natasha's smile disappeared. "You haven't even told him that you like him, did you?" her voice suddenly became sharp.

"What if rejects me sis? What if I'm not good enough for him?" Briefly, Katyusha didn't sound like an Imperial officer who is commanding a military ship, but as a lovestruck teenager who got struck with the ultimate question.

"WHAT IF HE REJECTS YOU!" To say Natasha was furious would be a colossal understatement. "Look at you! A 5.9 feet tall women with golden hair and emerald eyes, a body and a face that looks like they were made for a Greek goddess, callable of cooking 26 different cuisine, how can you be NOT good enough for him! Don't you remember how many guys asked you out in your entire academic life?"

"46." Katyusha said in a bemused voice. "You'll never let me forget that."

"And you rejected ALL of them!" Natasha voice is overwhelmed with frustration. "To this day you haven't even kissed a single boy OR girl! And you're 124 years old!"

"Sis, you're overreacting." Katyusha weakly tried to handle the situation.

"Overreacting? OVERREACTING!" Natasha apparently slammed her fist on the table in front of her. "After all this time, my little sister finds a boy she likes and even after sharing the same bulkhead for the last two years, can't tell him that she like him? Wait till mother hears about this."

"Mother!" Katyusha all but cried out in panic. "Sis let's make a deal."

"What deal?" Natasha suddenly became interested.

"Well I'm going to take one Captain Bokor's advice and scout the other side of the device for while re-enforcement arrives." Katyusha said. "If I find friendly aliens or no aliens in the other side of the device as you predicted, you won't tell this to mother. "But, if I find hostile aliens…"

"You'll kiss Boris" Natasha declared.

"WHAT!" Katyusha's face became instant red.

"That's the deal, take it or leave it." Natasha said with the old sinister grin. "Even the possibility of first contact is extremely low so you finding another Covenant is quite unlikely. That fact alone skyrockets the stakes. "

"Fine" Katyusha said after letting out a long berth. "I'm going to prepare for the ships for departure."

"Hey Katy," The suddenly soft tone of her sister voice haven't gone unnoticed by Katyusha, "Be careful" She said with genuine concern in both her face and voice.

A soft smile spared across Katyusha face, "I will be Sis don't you worry" with that Katyusha ended the communication and exited the Communications Room. She has a lot to take care of.

Act 4: What could go wrong?

January/11/2662

Milky Way / Hades Gamma Cluster / Antaeus System

Near Planet Hunidor

Onboard the Turian Dreadnought Pride of Palaven.

Mankanaze looked around the bridge. Both in front and around him are turian soldiers. Some of them are old and familiar, while others are new and young. Right now, all of them are facing him. Their faces sparkled with confidence and pride. They are among the finest his race has to offer and right now all of them are waiting for his orders, orders that they will carry out at any cost.

Hearing the sound of door opening, he turned his chair and saw General Desolas entering the bridge. His wide smile and the small nod answered Mankanaze's unasked question.

Taking a deep breath, he ordered his commutations officer, "Open a fleetwide channel"

"Yes sir." With a short reply, young communication officer quickly punched out a series of buttons on his panel. "Chanel open." He soon reported.

The Captain stood up. He knows right now, the entire fleet is waiting for his voice and the world they will carry. After taking a large breath, he began:

"To all the crew and officer of the 14th fleet, as of by now you all may heard of the mysterious ship that briefly entered this system and left. Many of you are speculated that it is from an alien civilization. That speculation is correct." Mankanaze took a brief pause so everyone can take the news. "It came from an unexplored region of space and we don't know anything about them." He once again took another pause as he personally doesn't quite agree with the later part of his speech but that is what the General instructed him to say. "While they could be part of an advance civilization all indication so far indicates a primitive society that has only recently mastered space travel. They are seems to be extremely reckless as they traveled through the relay with such a small and weak vessel that has little to no defensive capability against any kind of threat. Further, by reactivating the mass relay, they have shown complete disregarded to council laws," 'Laws that they have no idea about' He briefly thought. "This kind of recklessness and disregarded to galactic laws indicates that without proper guidance, this species can become as violent and aggressive as the Krogan and Rachni were. Guidance that only the Hierarchy can provide." He took one last pause and delivered the order he just received in his display, "In accordance to the Turian High-command order No:8960943, the 14th fleet is to neutralized this civilizations military capability and collect the species along their planets for Turian Hierarchy. "
He looked at his crew and said "Do your duty, follow you orders. We have led many species to enlightenment by our teaching, this species is fortunate to receive it. "

Everyone saluted the Captain in unison and returned to their posts.

"Nice speech, Captain," Desolas closed in and spoke to Mankanaze at a low voice. "The crew is more determined than ever."

"I hope the Spirits will guide us in the right path." Mankanaze said with deep concern in his voice.

"Relax, Mankanaze" Desolas said. "This campaign will be over in less than 3 weeks."

"What could possibly go wrong?"

A\N: One of the reviewer pointed out that I'm making extremely long codex entries. We let's just say it cannot be helped as I'm Geek when it come to technical details and I find a story incomplete without details like those. So I have two ideas in mind:

I can open a wiki. That will be difficult for me as I have no idea how to do it.

I can post them in Deviantart (I use the same account name) and those who are interested can check them out.

So which one do you think is a better option?
