AU Summary: World War II became the single most devastating war for Humanity. Other world beings called Sirens joined the war, and started killing off the human population without regard. After many decades of war, 60% of the whole human population have been killed off. The factions that remain have come together, and have been doing guerrilla war tactics on the enemy throughout the planet. SGT Costa with the Eagle Union's Army Sappers was en-route to an All-Faction secret meeting when his plane got attacked.

The ringing that usually came after a nearby explosion with unprotected ears, was in itself a blessing to him. Then the sensation of free falling, and overall wind rushing around him was enough for him to realize the precarious situation he was currently in. The cogs in his mind started turning, and the fog of the unknown started dissipating with coming to terms that he was no longer on board of the aircraft anymore.

Only the sheer darkness of below greeted his eyes as the trail of the flaming wreckage continued its course to the depths below. Beams of lights and conventional ammo being expended towards the sky quickly reminded him that he was indeed in hostile lands. The man quickly grabbed the small cord attached to his parachute, and pulled with all his might to release the one thing that could perhaps save him from certain death.

Of course that is… if he ever figured out where exactly he was landing to begin with and the hope that the ongoing sundering fire power wouldn't hit him or his parachute.

While the parachute did it's job in slowing his descent, he took the time to analyze the situation he unfortunately was in. His eyes trailed after the speck that was once the military plane taking him to the allied forces. Depressing the small button in his communication headset, he cleared his throat in preparation to hail anyone who happened to be alive from the small crew.

Only silence greeted his headset meaning all communications were down, dashing any miniscule hopes his heart had gathered. Anxiety spread upon him as visible land started to make way into his vision. Landing harshly on what only he could assume was asphalt, he buckled his knees to land on his side in a manner taught by his jump masters.

A super heated plasma beam hit a wall some feet away from him causing him to look up and grab his M4 Carbine. An enemy Siren quadruped unit was preparing another beam attack which he took as a cue to start firing at it's single mechanical eye. The quadruped screeched in pain and he shot a few more to suppress it for a while more. He scrambled to take off the parachute's harness, and promptly sprinted at the mechanical alien.

There were many types of Sirens in the known world. Most being out on the seas, but a few types have made it on land. All of the land types were towering walking fortresses on four stubby legs. They towered eight to ten feet in height, and weighed approximately one ton. Most common configuration was the beam emitter type. From their single mono-lens they would charge a super heated plasma beam that could punch through most materials with ease.

There were others with rocket launcher attachments, and others had what seemed like laser beam machine guns as arms. All 3 types were highly dangerous once they locked on to their enemies. They were also noted to be quicker than what their mass made them appear.

Bringing up his carbine and shooting off a few rounds at its head to distract it, he took notice of another coming in from a different path. Dodging a focused beam, he came up to the back side of the first one and, using his combat knife, he stabbed the energy spinal cord connecting the neck to the body. The siren gave one last chilling screech before succumbing to its death.

Using the now immobile body of the one he defeated, he maintained its body in between him and the other. One of the lessons hammered into him were that land Sirens needed ocular targeting to engage their weapons. So shooting their optical lenses actually caused them to shut down temporarily. The onboard repair system they had inside would repair the damage within a few minutes, but it would be enough to give soldiers an advantage. The surest way to defeat them was the thick cable on their back, which was quickly labeled the spinal cord. Those were the two known weak points of these types of Sirens.

Hearing the other moving around the dead body of its brethren, he quickly moved below the disabled one in preparation of sneaking around the second one. After letting the other giant move along, he came up to it and stabbed its spinal cord deactivating it from service. Before it did, it made a horrible screech that he knew would alert anything close by.

He knew that screech well. It was a disturbing sound that became known as an omen to all militaries around the world.. Or what was left of them. Scanning frantically at his surroundings, he noticed the building not far off. The scorched hole reminding him of how close he was to dying without even knowing it. Adjusting his assault pack, he quickly looked around for an entrance.

A broken window was the soldier's ticket in. Carefully pushing his pack in before him, he climbed into the building. He scooted to the corner, and finally breathed softly to get his bearings on what happened. Adrenaline kept his body on edge for any potential danger.

His plane was shot from the air, and he was lucky to be alive in the first place. Next, finding himself on clearly enemy land, and killing two land Sirens showed how much Lady Luck loved him. Now the current situation was him figuring out where he was, and surviving whatever support that blasted Siren called in.

Multiple heavy stomps outside the building was a clear confirmation of his own inner thoughts.

There was no rest for the weary so it would seem.

Putting on his assault pack, he carefully navigated outside the small room he was in. His M4 at eye level for quick bursts if need be. The more he navigated around the hall, the more it started to look like a former school of sorts. Clearing each room as he went along, the soldier kept his ears open for the stomping sounding right outside the building he found himself in.

Seems like there were at least a couple of sirens outside. Now which type were they was the question he didn't want to find out, but he probably did not have a choice in the matter at this point. Taking the stairs up, he scanned upwards before moving along. Having a second floor was a blessing in the disguise. While he had more rooms to clear, it also provided a tactical advantage in seeing the terrain he finds himself in.

He approached a window to one of the classrooms, and couldn't help frustration sink in at his current predicament.

It's a damn island.

An abandoned, now with Sirens, island.

He slid down the floor and once again gathered his thoughts. At the very least almost all Sirens were too big to get into the school, and since they hadn't started blasting the school down he could only assume they couldn't find him. Opening his pack, he gathered some supplies to at least get prepared for the night in enemy territory. The sound of thumping soon went away and he took a chance in peeking out the window again.

Of course. One of the Sirens was a rocket launcher type. The worst kind to deal with in his opinion. The beam type was the easier one of the two current ones. It seemed like both were heading to the island's plaza or town center. There they seem to seemingly deactivate though he knew from experience that they were never really off. It was a standby mode that could turn on at a moment's notice.

He saw squads wiped off like paper when they incorrectly assumed that they had the advantage over the supposed offline units. He would not make that mistake.

The soldier continued to take count of his supplies, when he noticed a peculiar line of light being projected onto the chalkboard of the school room he was in. He slowly moved towards the chalkboard, hoping that whatever it was that it wouldn't kill him. A drawer from the desk was cracked slightly letting out the blue light displayed on the chalkboard. Opening it slowly, his mind raced at seeing the object.

A blue shimmering cube.

It felt like he was staring at the foreign object for ages not knowing what to do with it.

What was it?

Could he safely touch it?

Was it radioactive?

Many questions came, with no answers to supply them with. With the near total annihilation of the human race, much knowledge was lost with the passage of time. Decades of the one sided slaughter made it so only knowledge pertaining to the continued survival of the race was the only thing kept and taught to the last remains of the once great civilizations.

You know what? He would probably die on this island anyways.

Grasping the cube in his palms, he examined the object with no small amounts of trepidation. The cube shimmered and pulsed in his hand. It was warm which was something he hoped had nothing to do with radiation. The object didn't do anything as far as he could tell with his experimentation with it. It seemed like an ordinary alien lamp thing.

Suddenly, he heard the sounds of sniffing right behind his ear. Swirling around in a panic, he saw.. Nothing.

But how?

He distinctly heard what sounded like a dog or cat sniffing his ear. Was his mind playing tricks on him? He immediately turned his attention to the cube in his hand.

Couldn't be this thing, right?

Deciding to put the lamp thing on the back burner, he walked over to his pack. There was not much he could do at this point with communications down, and night time preventing any sort of valuable information gathering. He knew that the burning aircraft must have landed in the water from what he remembered while on the parachute. More than likely the flight crew were dead.

He stuffed the cube in his pack and prepared to sleep for a few hours until day break. Sitting with his back to the wall, he prepared his carbine on his lap with the sling wrapped around his arm. If the Sirens haven't found him yet, then he hoped he was safe enough for a nap.

Hopefully.

Waking up to the aching of his back and a cat rubbing it's head on his chest. He semi-consciousnessly scratched the back of one of it's ears resulting in a purr of bliss from said animal.

His eyes snapped open and attempted to grab the cat. His attempt rewarded him with nothing but air. Sitting up he rapidly scanned the room also noting it was day time.

There was no cat.

That was the second time his mind was playing tricks on him. It felt so real to him though. Grabbing his weapon, the soldier took a peek through the window. He was hoping that with the daylight he would have a better understanding of where he was, and how absolutely screwed he was.

The two Sirens stood there on the plaza like gargoyles waiting to attack anyone coming to their territory. With most of the buildings razed down to the ground, he could clearly see the devastation brought to this island. Which begs the question,

Where was here exactly?

Beyond the two mechanical aliens, he saw something from the vague whispers of human history. Taking his binoculars from his pack, he couldn't help a small bit of hope take root in his heart. Half a ship jutted out of the water on the shore with a torn flag with the vague colors of the Eagle Union. Scanning the ship he saw that it was an aircraft carrier from the flat deck. Maybe he could find some way to communicate with his superiors in the Eagle Union.

The soldier grabbed his pack and started to head down the building. Seeing that the two mechanical entities not moving or patrolling anywhere, gave him a semblance of security for his task ahead. Skirting alongside a path at the edges of the island, the Eagle Union man carefully made his way around the center of the town square. No need to wake the robotic monster, and make life harder.

While traveling around, the soldier thought more of his situation. While the priority was to see if he could contact anyone of the friendly nature, taking out the twin walkers was in itself another top priority. Exploring this island and it's features could only be done it's entirety by eliminating the threat that those two Sirens pose.

Finally reaching the remains of the carrier, he double checked to make sure that the unfriendly duo had not moved since he last checked on them. Noticing that they have indeed remained stationary, he proceeded to find a way into the carrier. It seemed he would have some ways to swim to it, but that shouldn't pose too much of an issue.

Taking off the assault pack, he was planning on swimming without it when the cube inside started shining brightly. His eyes widened and he reflexively swiveled his head in the direction of the unpleasant hosts of the island.

They were awake and moving in his direction with a speed unbecoming of their large natures. Being at the shoreline he did not have any cover to get behind, which was soon proven true with explosions wreaking havoc on the sand around him. He threw himself on to the sand desperately hoping the volley would end and he somehow lived through it.

Sand and smoke filled his vision, while concussive shockwaves tore through him. His yells of pain were drowned with the destructive symphony of the missile volley. Even when the volley ended, pain continued to throb all over his physical state from the concussive blasts that washed through his body. Covered in soot and sand, the unknown soldier finally forced his body to kneel. Giant holes littered the sand, and his uniform was worse for wear.

The twin machines continued on their unrelenting path to him, their sights narrowed at him without remorse. The man stood shakily on his feet.

The sun bathed his back, and he posed his weapon at the eye of the rocket Siren.

"If this is how it's going to be.. I'm not dying like a coward!" He shouted with all his remaining might.

Round after round burst from his M4, yet none found their marks. The Sirens with clear vision of him, rotated their heads to avoid their weak point from being destroyed. Soon he spent his ammo, and while dropping the empty mag he grabbed another from his kit.

The Sirens loomed slowly over him, and he couldn't help but to look up at their angry red optical lenses. Snapping the charge handle, he saw their attacks being prepped to completely destroy him at close range.

"This is for my friends," He started aiming at the eye of the rocket Siren. It was prepping another volley at close range with no regards to itself or it's companion. He could feel the heat of the other prepping it's beam attack to incinerate him where he stood.

"I'm sorry."

High caliber rounds zipped past him and obliterated the heads of the sirens, dispersing any preparatory commands from their bodies. They continued to be fired from behind him and punch significant holes in the bodies of the quadrupeds. Once they stopped and felt it was safe to do so, he slowly turned behind him.

Only the lonely sight of the downed aircraft carrier filled his gaze. Searching for any signs of life, he started questioning what really was going on this island. He confirmed that there were indeed two life less Sirens beside him, so that wasn't a figment of his imagination. So who fired those rounds?

"Hello?" He called out.

"Is there anyone there? I am SGT Costa with the Eagle Union Army!"

No signs of life. His eyes focused on the aircraft carrier for it was the only thing in sight with guns big enough to tear apart the land Sirens.

Flowing white locks of hair, and a white uniform stood on board the deck. He could see the female turned towards him, and possibly looking at him.

"Hey! I am-" She disappeared from his sight. Literally blinking out of existence while looking at her.

"How?!"

Frustration didn't begin to describe his feelings. One moment he was seeing a beautiful female on board of the ship, and the next she disappeared like a ghost. If it wasn't for the fact he was literally looking at her, he wouldn't have thought that there was any life here. That and the sight of the two dead remains of the Sirens also proved a point.

He limped his way to his pack in preparation of swimming to the carrier. Checking himself over for any wounds, he gave himself a somewhat clean bill of health. Not counting the superficial pain and ringing of the ears. With the enemy killed, from what he could tell, he would be taking his time swimming to the half sunken ship. Tightening his pack, he took a deep breath before setting a slow pace to the ship.

The salt water burned some of the shallow wounds on his body, but he powered through it hoping that at the very least he could find supplies on board the ship. That and see if he was hallucinating about the woman on the ship. The cube was really starting to become very suspicious to him, and the probability of it causing hallucinations was becoming higher and higher.

After finally getting to a place that he could climb on board the ship, he took a breather while laying on his back. The water stinging his wounds did not help with his current state of mind.

"Can't really complain though. I'm alive after all," He said to himself while standing up from the metal floor.

Bringing his weapon at the ready, the soldier started to once again clear the rooms on the ship. He was meticulous in making sure he was alone on the ship, and scavenged any supplies he could find.

A couple hours passed, and he released a sigh of relief once he arrived at the bridge. Carefully navigating, clearing each room and getting lost along the way took its toll on him. He searched the room and spotted a radio. Limping to the communication device, he attempted to turn it on only for nothing to happen. There seemed to be no power at all along the ship, and it remained the same concept on the bridge itself.

Considering that almost all ships were destroyed decades ago, he should've seen that coming. Everything was filled with a thick layer of dust or a generous amount of water in some rooms. Spotting a familiar blue light coming off a random desk, he slowly made his way over. There was one of those fancy caps officers in the navy would wear sitting on an old desk.

A book sat beside with a title that ultimately surprised him.

"Eagle Union's Enterprise! No way?!" He grabbed the book almost reverently. The Enterprise aircraft carrier was a legend more than half a century ago. She was destroyed when a whole fleet took her out on..

"An unknown island. Fighting all by herself when all others fell." He whispered looking outside the windows of the bridge towards the island. The stories passed by the mouths of sailors and all branches of the military were widespread about this particular ship.

"This is where you made your last stand, huh?"

Costa gently picked up the cap, and examined the cube that laid hidden underneath it.

"Another one. What am I supposed to do with these things?" He said to himself while picking up the cube. Offhandedly looking outside onto the deck of the ship, flowing locks of white hair stood beside a gun turret. Next thing he knew, she disappeared without a trace. Stuffing the cube, book and cap in his assault pack, he quickly went down to where he last spotted her.

Once on the deck, he searched everywhere while walking towards the gun turret.

"Hello?"

Costa felt a little stupid calling out when he wasn't sure if she was real or not. Shuffling beside the turret, he took note of the direction it was facing compared to all others.

"Everything else is pointing at the skies, yet you… are pointing at them?"

This gun must be what shot the Sirens, but how? Something must be able to press the trigger. The mechanism won't fire otherwise. Yet the signs pointed that it must have been this gun turret that killed the robots.

"There is just no way. What is going on here?!"

A dainty hand laid gently on his shoulder. He whirled around at the ready with his weapon just to see nothing again. After a moment of searching, the soldier lowered his weapon completely. He sighed and laid a hand on the turret.

"I think I really am going crazy. If I am though… At the very least I want to thank you for saving me. I could just be talking to myself, but I don't care anymore. So thanks, girl. Looks like even in death you still fight on." He gently patted the turret as though it was alive.

Though it may very well be at this point with his state of mind.

While he was no expert when it came to the Navy, he was pretty sure the ship had no way to function at all. It was torn in half, and missing some major components if he guessed correctly. Also any food on board the ship was spoiled and unusable at all. Most of the medical stuff was expired, but he still took off the bandages and similar items just in case.

One thing he was thankful for was the discovery of a simple usable cot. He was taking it with him to the bridge to sleep in for the approaching night. While it was an older style with a steel frame instead of aluminum, it would do the job of providing a somewhat comfortable sleep.

"This thing is heavy though," The soldier complained.

Once on the bridge, Costa started to unpack his assault pack and set up the cot. Taking off his boots after a few days of not seeing his feet, he could smell the need to change socks and his uniform in its entirety. While scavenging the ship he did find a white officer uniform that was the only thing he could find that was usable at all. It was actually in fairly good condition if he was honest.

"Well it's not like I'll get in trouble for breaking protocol in wearing this. I'll use it tomorrow. For now I need to get some shut eye."

Laying on his cot, he eyed the dim light casting off his assault pack. Each cube has its own pocket in his pack so he could differentiate either of them. It also served the purpose of keeping them from touching one another, which he didn't want to test out to see the results of such an experiment.

Reaching over and taking a hold of the cube found on the ship, he gently rubbed his fingers on the warm object. The man still questioned the purpose of these alien objects. This one being discovered here on the ship, he could only guess that it belonged to this ship somehow.

"But in what way? Do you belong to Enterprise or are you just something random thrown on board the ship? Though then again you were hidden in that cap, so someone must've known about you enough to hide you. So… what are you?"

Suddenly visions of the same white hair girl filled his mind. She was absolutely breathtaking. She wore the exact same white uniform with a black flowing coat. To match it off she wore the officer cap on her head, and a bald eagle seemed to find solace on her arm. The young lady looked at him and moved her mouth as if she was speaking to him. No sound came from her lips, and all he could do was try to read her lips.

"What are you saying? I can't hear you. Are you saying I am..."

He tried to decipher her words, only to receive multiple head shakes for every attempt he made. The beautiful young lady seemed almost disappointed at not being able to properly communicate with him. SGT Costa felt frustration and anger at himself with his pitiful attempts at trying to understand her. Being bad at reading lips was one thing, but also having no knowledge of who she was put a damper on his spirits.

He tried to remember any other details from her. The couple of times he saw her were on board the aircraft carrier. Specifically where the gun turret was on the deck. Then he remembered looking at the gun turret and finding it impossible that it could've fired at the enemies with no one to pull the trigger. Not unless of course if the ship were to be alive and did it itself...

"Wait. You're not saying that you're Enterprise are you? Are you Enterprise?"

A small smile and nod of her head was the only indication before he was forcibly taken off the trance like state he was in. Blinking away the cobwebs in his head, he noticed the cube was glowing brightly and it flew away from his hands. It started to float in place and became more bright as the seconds ticked by.

Then a big flash of light blinded him, making him put up his hands to shield the sheer brightness from the eyes. He peaked through his fingers once it died down, only to gasp out loud at what he saw.

"I am Eagle Union's Enterprise. Greetings, Commander."
