Chapter 2: New Identity, Same Capability.

Be the light that guide us...

UNSC Enterprise, Epoch-class Heavy Carrier hull number CV-600... This will be my final battle after one too many...

I shall not fail.

A pair of maroon red eyes fluttered open, obscured by a thick black glass of a helmet visor, droplets of water hitting the surface of the said visor slowly leaving moist marks on it. The owner groaned, both from pain and physical exertion, pushing herself off of whatever she was lying on only to froze when realization hit her with the might of MAC round.

She shouldn't have eyes.

She shouldn't have feet.

Panic filled her heart for the briefest of second until military discipline took control, she tried to regulate her breathing to keep calm and began to assess the situation. Activating her HUD system, which somehow took the same order when she was still a ship, her vision suddenly filled with various warning messages from her internal and external systems.

Reactors, hull integrity, weapon system and sensors took utmost priority almost immediately above all, giving her full readouts of her current condition. She spared them a brief glance before pushing the messages clear and instead directed her gaze below to look at her own body. A body that somehow took an appearance of human female, cladded in what she recognized as Mark V MJOLNIR Power Armor those Spartan super soldiers she once transported to an outer colony world wore. Tentatively, she brought her hands up to examine both appeandages and for the first time in her life she knew how it felt to have fingers as she flexed the ten digits experimentally, despite the initial clumsiness it didn't took her long to master her own fingers and soon she had full control of them.

This shouldn't be possible. She shouldn't have human body, she should be dead.

The latter she was certain of because she could still remember how a CAS-class Assault Carrier tore her hull with its swarm of Plasma Torpedoes, and she sure could still remember the scream her crew let out when she failed them.

The ship-turned-woman bit her lip, a foreign feeling bubbling inside her stomach, a feeling a moment later she realized as fear. Myriad of these emotions swirled up together, creating a storm of unknown sensation she never felt before. Her new consciousness struggled to register every single one of them.

Her crew, they were all dead, she couldn't hear their chatters inside her hallways and bridge, she couldn't hear the usual squabble the Marines would have in her hangars, she couldn't feel the comfort knowing she had the best men and women fighting with her, alongside her. They were all gone, only silence except the sound of thunder and rain permeating around her, not even the dark of space ever made her feel this lonely.

She looked up, trying to distract herself from such frail thoughts, staring at the dark sky numbly. At least one thing for certain that she was on a planet and not a gas giant, or worse a black hole. She couldn't make sure which one was better though, being sucked by a gravity field strong enough to tear her apart or being in this confusing situation.

In the end, the need to acquire more information won out. She brought up her damage control report again, silently reading through various warnings and alerts in hope to get a bead on what actually happening to her. The last video file her system recorded did nothing to appease her confusion and instead only served to make her unease, it's her final battle defending planet Reach, the last bastion for mankind, which led to her eventual doom. Nothing in the video could be used to help her finding answer.

In other word, she just popped up literally out of nowhere to this planet with zero clue how and why. It was frustrating and concerning at the same time.

There has to be an explanation... There is no way I turned to human just like that...

Once again, she looked down. Frowning deeply when she noticed things she didn't notice earlier about her appearance. Her weapon systems read normal, she still retained her entire armaments with her, but their physical forms were all changed to fit her new body if not straight up minimalized from their normal size. Her single 56A2F9/Rapid-Fire Variant Light Magnetic Accelerator Cannon was resting behind her right shoulder with a metal arm supporting it, its long barrel jutting up to the sky with somekind of handle near its tip, its rear compartment curved like the magazine feed used in M41 Rocket Launcher but instead of disposable rocket tube a magazine belt was attached to it running down to her back where her reactors were, leading her to believe it's a power supply line instead of for actual magazine.

The dual Mark 15 Breakwater Naval Coilguns took more drastic change than her MAC, at least her MAC still had a resemblance to its former self unlike her coilguns which changed to what seemed like some sort of handguns with coils around their barrels. Both weapons were stored on her thighs, clasped in magnetic holsters. A quick inspection revealed they didn't have any visible magazine feed just like her MAC gun, but the moment her fingers closed around them, they suddenly lit up with blue-ish color especially around the coils.

So... They don't exactly need ammunitions, at least not like how firearms should be. She thought drly, looking at the ammo counters on the right corner of her HUD, despite not requiring continous ammo cycling they still had limited shells, the reading showed they had the exact ammunition count when she was fully stocked.

Scoffing in disbelief with how ridiculous it was, she quickly returned both naval coilguns to their new respective places. Brushing her fingers on her Archer missiles pods now positioned on her left hip and did the same thing to her Bident missile on her right. Both guided weapons were again supported by the metal arms protruding from her back, it seemed the metal arms were acting as her weapons foundation and were the most vital part of herself aside from her engines and reactors judging with how most of her point defense guns, now smaller in numbers and size, were arranged on them.

The autocannons she had to fend off Covenant fighters and transports were on the other hand, covering her arms from elbows down to her forearms. Despite looking far smaller than their original size, she somehow knew they could still deal the same damage, no matter how illogical it was.

At this point, she had resigned herself to trust what her intuition told her.

While her MAC occupied her right side, apparently her hangar was now moved to her left shoulder blade, the blast shields were visible amidst the dark plating thanks to the guidance lights once used to help the pilots land safely illuminating it. The prospect brought a new question to her rather than answer, about how would her complement of aircrafts operate. Like her weapons, she got a full combat readiness status from her squadrons but now without any pilots she wasn't sure how they would fly, or how they would look for the matter.

Only one way to find out.

"Enterprise actual to Mercury Flight, prepare for takeoff and conduct in-atmosphere recon" Enterprise ordered to one of her many Broadsword squadrons. Almost instantly she receieved literally a green light on her HUD, followed with a faint whirling sound on her back as the blast shields covering the hangar being lifted, exposing her internal structure for a brief moment because as soon as the Broadswords lurched high into the air it quickly shut itself again.

She was sure whatever passed as her brain almost stuttered to halt as she saw the four buggers disappeared amidst stormy cloud, transforming to a full size Broadsword Fighters. More so when she felt the aircrafts communicate with her through somekind of mental words she didn't understand but could comprehend.

Enterprise blinked once, getting rid of the brain melting thought and the odd sensation her flight group gave her. It seemed her sitution was more severe than what she originally predicted. A space ship easily 35 million metric tons in total displacement, equipped with one of the heaviest armors and weapons humanity ever produced, turned to a woman cladded in Mark V MJOLNIR barely a ton in weight.

And let's not think about her height, because she was certainly not 2,5 Km.

She wasn't even a SPARTAN to begin with, how could she wear a MJOLNIR anyway.

Pulling a digital note, she began to make a log about her current predicament, all known facts and what to do with them later on, she almost done when she noticed she also capable of standing above water surface then promptly added it to her NEED SCIENTIFIC RESEARCH section. If there was something a space ship feared, it was the unknown.

Activating her sensor suite, Enterprise almost cringed when alarm blared in her helmet nearly defeaning her. She hastily deactivated the warning system and double-checked the reading, it seemed her sensors suffered heavy damage with most of them inopt, with only a handful still operational. Bio-detector was offline, her main and secondary LADAR were offline, RADAR was only working on 20% capacity, and her communication suites both for real space and Slipspace arrays were busted with only short-range radio still working. The damage control reported the faults were mostly mechanical, meaning she couldn't just hard start the systems and hope they'd fix themselves.

A mental tug on the back of her head brought her attention, a single message suddenly popped up on the front of her vision. It's a data-link from her Broadswords, displaying a real-time video feed. At first, she wasn't sure with what her fighters showed her but a quick enhancement on the camera later and it was clear that something was there.

Or rather, someone.

According to the Broadswords, a small fleet of wet navy vessels were heading her way, they were consisted of fifteen ships in total, ships with design unregistered to her database. Each were painted in vicious looking dark color with some glowing red lines running amidst the hull, they were also armed with small caliber anti-ship armaments which might pose a threat to her had she been a 21st century vessel herself they seemingly resembled. Too bad she wasn't.

Still, there was too many unknowns. Apparently there was somekind of military organization in this planet, meaning it's habitated and not just some random barren land like she initially thought. The first question was who or what were they, since UNSC only used blue water vessel scarcely for a world with vast water surface it threw the possibility out of equation, and there was the fact her vast databanks ranging from the start of mankind's history to today failed to clue her. Ever since orbital warfare became a thing, wet vessel was considered as obsolete, so either this local inhabitant was too primitive or too advanced they were confident their surface ships could take out a space ship like herself.

Both yet again opened up more questions than answers.

There was also a possibility of them being Insurrectionists, but according to her records the Innies never operated any wet vessel larger than Blue Navy classification of Frigate, which these ships exceeded almost to Cruiser size. She checked her weapons once again, double checking and triple checking everything was accounted for possible upcoming engagement. If they were truly a part of Insurrectionist terrorist group, she wouldn't spare them a chance.

Deciding to investigate by herself, Enterprise quickly recalled her fighters back, there was no point keeping them airborne and she didn't want to risk losing them until she found a way to replenish her supply. Enterprise then began to activate her functioning engines, mindful with the fact she only had one fully operational sub-engine while her other one barely stabilizing on half of its power output. After a slight struggle in balancing herself thanks to her engines new positions directly on her boots instead of back, she finally succeeded keeping herself steady, and soon she was on her way to the direction where the unknown fleet was.

She watched as her Broadsword made a landing turn from the cloud, giving them all clear and raised the blast shields of her hangar. Much to her fascination, they suddenly transformed to four golden balls of light before entering her hangar. She checked their status and was surprised to find they were ready for another deployment.

It usually took minutes to refuel and rearm a Broadsword, not barely a second.

Frowning from yet another illogical phenomenon, she barely flinched when she smashed through a rather large wave, breaking it to countless small droplets. She hoped whatever or whoever these unknowns were they could give her an answer for her many questions, at the very least to an extent. If not, she had the full authority to make sure she operated at a hundred percent capacity, and seeing how her current predicament hindered her from working fully UNSC regulations stated she could take any ways necessary.

That including by peaceful or violent approach. She was ready for either.

Enterprise pushed her sub-engines at their best capabilities but it's hard to maintain even speed with one exhaust sputtering black smoke, still she managed to keep her speed above 80km/h, soaring high above sea level so she didn't have to deal with its raging waves. Her HUD had taken flight mode, enhancing her sight and giving her real-time readouts on her surrounding through passive sensors, Infrared and Thermal were amongst her handful operational sensors, feeding her vision with their datas.

The other non-combat essential sensors she had onboard gave her the data about her vicinity, revealing the environment and atmosphere were similiar to that of Earth's. It didn't surprise her since there's living being in this planet, she even swore she saw a fish down below. The gravity also almost similiar with mankind's home planet with only a slight off on the charts, barely 2% stronger, however such difference could still affect a hundred years worth of evolution.

She didn't want to deal with some freak sea monsters yet, especially in the middle of nowhere.

It could be useful to test my weapons... I don't know how they would perform now. She thought distractedly, running a little simulation in one of her system subroutines.

Discarding the thought for later, Enterprise glanced at the small map her Broadswords provided her, using it as a point of reference to her and the unknowns' positions. She was roughly 10 kilometers short, an extremely close distance in sea much lest for a space ship, from reaching her destination. She didn't wait to issue general quarters and brought her weapons online, dully noting how her point defense guns and autocannons began to move on their own seemingly tracking invisible targets, while her MAC hummed with power.

Soon, her targets came within range of her powerful sensors, sailing undisturbed and unaware with weapons far advanced than what they possessed only a motion away from being unleashed to them. The ship-turned-woman kept her distance for a few more seconds to formulate a plan, observing the small fleet with utmost precision. Every curves, every angles and every weapons they had were slowly being assessed by the woman, and once she had got enough she finally made her first move.

"This is UNSC Epoch-class Heavy Carrier Enterprise broadcasting in all open channels, to unknown fleet consisted of fifteen black-colored ships bearing from 130 degree South East to 302 North West, halt at where you are and identify yourself, failure to comply will be met by force" Enterprise demanded, playing the message in loop and broadcasting it through any known communication methods be it Morse or even tight-beam signals, anything she had that was still functional.

The fleet kept on forward for a few more kilometers, seemingly ignoring her warning, she'd tried to use every known languages be it human's or ones which were a native of the Covenant species' but neither garnered a respond, making her believe this was an entirely new species. Enterprise was about to send a First Contact Package every UNSC ships possessed, detailing all the necessity of greeting about humanity and their intention of peace, that despite her earlier order that could be easily interpreted as a threat she actually prefered peaceful contact, when the ships suddenly came to a sudden halt 5km away below her hovering form.

And they just stopped there, unmoving with zero sign of life whatsoever. It's almost like someone cut their power off and left them be, a mass of floating hunk of metal in the middle of ocean only the sea caused them to sway. Enterprise tried to find any sign of living being, anything to clue her of the native of this planet when suddenly her radio screeched with static.

At first, it was just some unintelligible buzz of nothingness leading her to believe her communication suites were getting interference from the planet's magnetic field and almost passed it off as system malfunction when suddenly a voice speaking in unmistakenly English language echoed amidst the buzzing, a voice clearly of human origin.

"My, what a rude way to greet someone..." It said with a mocking hollow giggle, prompting Enterprise to frown. There was something wrong about it that caused her to put up her guard instantly.

"I'm not going to repeat myself again, identify yourself" Enterprise ordered, hands moving to her dual naval coilguns. "Failure to comply will be met by force"

There was a moment of tense silence, only punctuated by the cracks of thunders around them as both factions seized each other up. Despite Enterprise's disadvantage in number she still held her ground, giving her intention clear that she was more powerful than what she seemed to her opponents. Whoever these unknowns were, they certainly had made contact with mankind before if they had known how to communicate in English. Even the Covenant with their technological might needed a direct contact to translate a language.

Any other scenarios were straight up impossible.

Finally, a more quiet tone of her unknown dialer reached her, this time more clearer than before Enterprise could deduce it's a female she spoke with.

"You're not from around here, aren't you?UNSC... Epoch Heavy Carrier... Your designation CV-600... Those all don't exist in this world". In far more smaller tone she then added "But not your name... It always exist..."

Enterprise ignored the last comment. "You know human language, you must have made contact with humanity before-"

"Made contact?" It said, this time a deafening laugh followed it. "We made contact with mankind everyday, we watch them live and sail this realm from the deepest of ocean. We ravaged their lands and burn their seas, filling their life with despair and agony is our daily basis". The voice paused, as if thinking about something before it continued "I can feel something within your soul... You are a new reborn, aren't you? Your newly projected spirit is filled with unadulterated hatred and anger, unmolded at its purer form. What a delicious feeling"

"... So there is human habitating this planet?"

"There is... They've been here before we have, waging war against each other in the thirst of blood, how stupid".

Enterprise blinked, mulling the new information. So there was human in this planet, one that had been a local for quite long time, maybe they're from a lost colony ship or even an unregistered colony world?

She logged the information. "What is this 'we' you are refering yourself as? What are you exactly?" Enterprise began in hope to squeeze as much intel as possible, right now all she needed was knowledge especially one involving her condition.

It seemed this unknown also thought of the same thing.

"You ask too much... How about I ask you for a change? One question for the other"

"Very well, but answer my earlier question first"

"Fine..." The voice breathed out. "We are known by many names, Living Lies, Twisted Maidens, Sea Whisperers... They were ones of many. But to this world we are simply known as Siren"

"Siren..." Enterprise muttered, testing the word with her new tongue. Her system automatically designated the ships based on their classification and allegiance, the previously yellow colored words 'Unknown' now were replaced with red pulsating 'Siren Cruiser 1' all the way to 15 . At least she knew what she up against.

"Get it? Some says the first step to defeat your enemy is by knowing them, so please tell what is this 'UNSC' you said you are a part of"

Enterprise's armored hand twitched beside her at the implication, her reply came in a solid and simple tone. "United Nations Space Command"

"Space Command...?" The now identified Siren uttered almost hesitantly, as if unsure with what she heard.

"Yes, now's my turn. You mentioned something about being here, since when?"

The Siren took a bit longer to respond, a fact Enterprise noticed instantly. "We've been here for decades, since the Old War"

"Old War?"

"Ah, that's two questions in a row, Enterprise..." She said with a giggle, earning a scoff from the space ship. "My turn, is it true that you are a space ship born from different world than this?"

"Yes" Enterprise replied curtly, not wanting to reveal too much information from her end. "Now answer my earlier question"

"How straight forward, I don't like it" The Siren commented but yet again Enterprise ignored it and instead patiently waited for the more valuable answer. "The Old War, was a war humanity waged amongst their own kind. By their measurement of time, it happened approximately 30 years ago from today. When we arrived to this world, the war was nearing its end with Union solidifying their hold on Sea of Seas and quickly pushing their influence to the East where another power responsible for awakening their wrath resided, while the cunning Knights of Royal and her allies finished off the Chosen Blood on the North. It's endearing to see how they then banded together to fight us Siren, even after so long drowned in each others' blood, truly a fascinating species"

Banded? They were no longer allied themselves to fight these Sirens? But why?

"Something troubling you? Is it the part about them seceding from their alliance?"

"Is that going to be your next question?"

"It is"

"Then the answer is yes" Enterprise replied curtly. "Tell me about this alliance and the factions inside"

"That's gonna take a bit of time"

"We have time"

"I beg a differ" The Siren countered, earning an alerted gaze from Enterprise.

"And why is that?" She queried sharply at the declaration. Enterprise never got the answer however because suddenly one of the ships consisting the Siren fleet exploded into a blazing ball of fire, throwing metals everywhere into the sea. "What's happening?!"

The Siren sighed before she replied "They're here, it seemed you'll get your answers sooner than expected. What a shame I actuallly have plan with you"

There was a loud buzzing sound filling the air, followed by another and another slowly drowning the cackling of thunders around them. Enterprise's point defense guns abruptly turned to the sky as metal objects continued to fall from above the cloud surface, objects she quickly analyzed as bombs, following these bombs were squadrons of piston aircrafts usually found in museums or history books.

They made a diving run, engaging the most strategically positioned ships in the fleet. Tracer rounds filled the sky as anti-aircraft armaments tried to repel the coming strike but only some of them managed to land a hit and score a kill.

The attack didn't last for more than 2 minutes yet the result was devastasting for the Sirens, whatever remained of the fleet moved closer to form a tight formation. Enterprise however just stared during the whole ordeal, conflicted between helping and just observing. Her mind came to halt for a moment due to the amount of informations she receieved and more questions that popped up after the attack.

Enterprise managed to catch a glimpse of the attacking aircrafts with one of her powerful onboard cameras, and to say she was surprised with what she saw would be an understatement. These aircrafts were registered in her database as Douglass SBD Dauntless, a type of scout/bomber aircraft largely utilized by the United State during World War 2, meaning it had been out of service for centuries. They're no longer exist much lest still in active duty.

So seeing them by her own eyes in action was probably the most unexpected thing she would have ever imagine.

"What is going on here..." Enterprise muttered numbly. She was confused, angry, and this burning sensation on her abdomen kept throbbing nonstop since her awakening.

"They were a part of this alliance I mentioned, these aircrafts must be from one of their carriers. The human probably saw you when you descended"

"That didn't even give me any meaningful answer" Enterprise retorted, her burning gaze turned toward the Sirens. "What is your intention in this world? Why do you chose to be mankind's enemy?"

"We do what we deemed necessary"

"Necessary? As in for yourself or something far more larger?"

"I'm afraid I've said too much"

Enterprise nodded, sucking in a deep breath and released it slowly. On her Radar a blip appeared but she ignored it in favor of replying. "Then so be it. UNSC First Contact Protocol Article 3; By intentionally showing a direct or indirect threat to humanity, I am hereby order to neutralize you through any means necessary and gather whatever combat information I may acquire to prepare mankind from further prejudice you and your kind might inflict in the future" There was a hiss as the Archer pod on her hip slid open, revealing the warhead of one of the best anti-ship missiles UNSC had.

"So be it. But heed this, humanity will keep on forward, and those who you hold dearly will eventually forget you, your affection to them will doom you".

Enterprise's reply came in a solid and unwavering tone "I don't care, their survival is my utmost priority above all, even myself". And with that, the Archers launched forward, leaving a trail of angry blue fire on their wakes. Five of these missiles raced in an organized formations, each had their own targets of destinations. "Farewell"

"Until next time, Void Wanderer"

The missiles struck home, all but obliterating the ships before Enterprise. A single Archer missile was rated to cripple smaller UNSC ships, ships equipped with enhanced armor plating liker her. Even Covenant ships with their nanolaminate armor couldn't withstand a full swarm of Archer missiles, granted once their shields were offline. These ships with their inferior armor might as well used paper for their non-exist armor effectiveness.

It was comforting to know her weapons were as effective as they were when she still a ship.

When the dust settled, nothing but burning piles of metals left of the Sirens, slowly sinking down to the endless bottom of the ocean. Those that were destroyed by the aircrafts however slowly disappeared into the thin air, as if their existances were merely deleted from the world leaving nothing to remain. Enterprise observed the occurance with keen interest but only mild surprise, despite how unusual it was she just passed it off as another surprise this unknown world had in store.

Another squadrons of the piston aircrafts made a passing run above her, their bombs still attached on their underbelly never had chance to be used, only when she was sure they had no intention to attack her did she let her point defense guns to ease up. Enterprise then slowly descended to the water surface, literally testing it before cutting her engines offline.

For a moment, she let herself got lost in the silence, thinking over the latest development of her situation. Aside from the fact she found a world habitated by human of unknown origin, she also found another alien entity dead set to kill every human on their path because of reasons, it seemed mankind would always find more enemy.

Still, these Sirens, while not as technological advanced than the Covenant, they managed to disrupt a whole world and terrorized its occupants. It reminded her of the Insurrectionist group UNSC had been fighting before the start of Human-Covenant War, a group she had fought a few times in her earlier time of service roughly a few years after she was comissioned into the Navy.

The comparison was... comforting in a way.

An Epoch-class Heavy Carrier like herself was designed for a single ship deployment, meaning she was decently equipped to fight a whole world alone. While her reach wasn't as far as that a Supercarrier like Punic-class, she was still considered as a symbol of UNSC Navy might for being known as the heaviest armored Carrier just below the Supercarriers. Enterprise's resiliency was proven during her entire 50 years of service, starting from 2502 until 2552 where she finally succumbed to her wounds. From the day she was born, Enterprise had been pounded by missiles and cannon shells, seared by lasers and burned with Plasma weapons far too much than she could count, there was even a moment where she receieved a MAC round on her starboard from a hijacked UNSC Frigate during her campaign in Operation TREBUCHET but in the end she always prevailed.

How could a single world be different?

The blip on her Radar returned and she turned toward the direction where it came from, whatever it was it's probably pretty big to be detected by her barely functioning Radar considering how the aircrafts didn't appear on it. It's a good thing her missiles homing algorithms could be toggled with prefered systems so to not rely on a single targeting unit, else her missiles would scatter everywhere.

Standing a few meters before her was a woman approximately on her early twenty. She had a shoulder length silver hair which was rather unkempt, around her neck was a tattered black cloak covering a white shirt. However what caught Enterprise's attention the most was the bow she was holding, it had some sort structure on it that resembled a bridge of a ship, and the black themed landing deck on her side seemingly supported by a single metal arm running down to the woman's back unlike her equipments which was mainly fused to her suit.

Their gazes met for a second, emotionless black glass and stoic purple clashing together in silent battle. Enterprise's MAC hummed to life as the metal arm supporting it moved the weapon to her side as if to offer it to its rightful owner, she didn't wait to grab the handle near the tip, holding the cannon in reverse grip with its barrel pointing straight to the unknown woman. The fact this woman shared the ability to stand above water surface was enough evidence she's also a ship like her, if her equipments weren't enough proof, and since she hadn't seen the true form of this Siren Enterprise could only assume.

The space ship blinked and the image of the unknown girl shifted, instead of a short haired woman she suddenly grew a long silver hair which reached down to her rear, her tattered cloak also changed to a loose black coat that revealed her shoulders. Her bow also gone, and the flight deck on her side gained a pattern of yellow on its surface and a number 6 near the end, it also appeared to be damaged with cracks and blast marks marring its surface.

While her face still retained the same facial structure, a shocked look however replaced the previous stoic expression she had.

Enterprise eased her finger around the trigger of her MAC, the power counter on her HUD stayed the same on 5% capacity however. She tried to find the previous woman but couldn't find her anywhere and decided to check on her recording, only to frown when it's revealed it was this woman she had been staring at from the beginning.

Shaking her head in disbelief, Enterprise focused her attention toward the woman again, activating her external speakers and said the very same thing she said to the Siren earlier.

"Identify yourself"

TBC

I didn't expect this story to receive so many attentions because honestly I wrote it out of boredom, but oh well.

Also here are the asnwers for your questions, I really appreciate your reviews but I'll only point out the most pressing ones.

-The Siren didn't plan for Halo Enterprise's arrival.

-Yorktown is still alive

-The original idea was to have Punic-class, but I reevaluated it since the lore about Punic is too limited and I don't want to throw some random guessing.

-Halo Enterprise shares the namesake of USS Enterprise, she comes from 'our' world where Siren dooesn't exist.

-The characters won't have any abilities like in their game counterparts, however what abilities shown in the anime will exist in this story.

Also here some issues I would like to address:

-I couldn't find any canon source that details about Epoch 2554 retrofit, what I found is Fanon source and I don't want to take a reference unless from canon. Besides, I already hinted about UNSC Enterprise eventual destruction above Reach and as we know the planet fell on 2552 so there won't be any retrofit or advanced energy shielding, any other Post-War techs really.

-I don't know what the Mark 15 Naval Coilguns exact way of operation, but based on the name it implies it was some sort of coilgun which as we all know is the actual explanation of Magnetic Accelerator Cannon. My guess is the 'Naval Coilgun' is actually a preceding design for Mini-MAC, so in this story they will work in the same way.

-Also, can someone explain to me how EXACTLY Bident missile works?

That'll be all, see you guys later.
