Unknown Location, Outer Space.
The separatists were flown away from the planet and onto a light battleship orbiting Azeroth. Once they were in the ship, they found other Horde separatists who were friendly to their friends of the Alliance. But they were all wondering about this faction. The UNSC reminded them of their previous enemy long forgotten in time, but this one was tolerable of the presence of the natives who served their kings once before.
Some of them felt their lives had moved to a new chapter. They saw the ship floating away from Azeroth, passing through an orbiting gas giant that wasn't even there before. An ice moon was spotted in the distance. That's where the ship was going, but how will they breathe in the vacuum of space? Luckly for the natives, some were mages. They can think of a way of breathing in space.
Except when they landed on the tundra part of the moon, the people were breathing like normal when they went outside the ship. The air was converted to actual oxygen by the generators that altered the atmosphere. Other than the absence of trees or leaves, there was buildings all over the area, ships were parked in hangars. Military equipment were everywhere. Troops welcomed the natives normally, then went back to their tasks. More construction were further ahead, or they were mining quarries.
The main building was at the frozen lake, which was typically the HQ. The doors opened to a courtyard which was decorated nicely, and by surprise. Kirin Tor mages were creating a stable air supply throughout the facility and creating portals linking back to Azeroth. More separatists from other ships came into the yard. The main commander was awaiting for everyone to take their spots. She rested on a floating chair, and her legs were clearly disabled.
"You sure this is everyone here?" The commander asked a elderly scientist, obviously waiting for everyone to get here.
"That's what the teams can recover at the moment. Now's the time to start." She replied to the commander. The bio-scanner tagged 80 natives in the yard, and 250 more in other areas of the moon.
She emerged from the inner door to the courtyard in a stand. Beginning her speech without feeling afraid of the many rebels that wanted to be here.
"Welcome to the UNSC Marines Corps.. My name is Sarah Palmer, Commander of 74'th Frontier Battalion." She began slowly to make sure that she doesn't make a fool of herself.
"We're the main military forces operating on Azeroth against your former allies, the Alliance and Horde are our main concern. In fact, some of our secret operatives knew you were tired of your people in executive power. You risked your traditions to leave your past behind, but you expected a new outcome in this group. We can offer you everything we can give you. We're all over this galaxy of ours, and we can give you the right to travel to different planets to live as a citizen, have a working job or to start companies for yourself and your family." Palmer offered the natives the right to bear citizenship, allowing full rights to everything they can offer to them.
"Or.. You can join the Marine Corps and other UNSC affiliated branches. You can help us fight against our enemies with a vast collection of powerful weapons, up-to-date intelligence, and aid cooperative operatives and other operations across this Solar System. All of these can help you in many ways you can imagine, but which one will you choose?" She then offered for them to join the UNSC or any other branches of their military forces.
Many people rose up and made their decision. A good portion of them chose the UNSC, and the personal had to follow them into training rooms. Only 25% chose to be citizens of the faction. Not many people had died trying to get to the UNSC today, a shameful display by the Alliance and Horde. More will betray their clans to fight alongside their new friends or live in the stars.
The War Games - Simulation Board.
A month later. The rebels had been training around the clock in various times, getting used to their new combat environment in some training rooms that offered simulations of the battlefields of Azeroth. They all paired against their former supporters or the deadly legends of the Burning Legion's ranks. Many separatists had entered into the military into different branches. Many went into the armored trooper squads, some into Special Forces. People chose to be the soldiers or remained as simple warriors or the many druids, priests, paladins or mages of Azeroth.
Others had gone into a rumored super-soldier program. The Spartans were genetically enhanced super soldiers that can perform in any operation. They sport in the top-of-the-line power-suits with energy shields. Many heroes represented the Spartans for their super strength and their mastery of any weapon.
The program had gotten fame in the Spartan-II operatives, but controversy was followed when they were actually children being trained for this super soldier program by an secret government organization. Then the genetic experimentation had either severely crippled or killed them, but it had produced a very deadly set of soldiers that went toe-to-toe with an alien race. Most of the UNSC nearly lost the war and face utter extinction, but the Spartan-II operatives' genetic enhancements, durable power suits and tactical supremacy were the prime factors of securing a miraculous victory over their enemies.
As time went on, the Spartans became more widespread in recruitment of official UNSC soldiers. But sadly, the genetic enhancements were lowered to reduce the chance of fatal damages or death to the candidates. It produced lowered strength and neural improvements. The Spartan-III and Spartan-IV were the examples of expanding opportunities to other marines.
However. The UNSC was only here for a year and one of the newest Dragon Aspects had a solution to their problems. The Spartan-V program was recently started because of the intervention of the Aspects. Their magical power had simply combined with the genetic experimentation processes that was under the safe threshold, it had created no damages inflicted on the body, but yet created a stronger super soldier than ever before.
The subjects would even resist artificial gravity about a hundred time stronger than Azeroth, and it made the armor weight completely nothing at all. It was paying tribute to the successive Spartan-II program, which had produced Spartan-117, the hero of the war that separated victory of extinction of their civilization. He fought entire armies almost alone, but yet won at most major battles across the galaxy.
Afterwards. The War Games in the UNSC was a popular way of training recruits, facing them against others in simulations that sometimes ended up as a sport between Spartans. When the UNSC began its operations on Azeroth, they expanded their training to face off against the Alliance and Horde, and the other target was the Burning Legion as well. The Marines were to expect Azeroth's tricky environment to avoid casualities as much as possible.
Natives had no clue what to expect. At first, they were afraid that this was real. But by logic, they were inspired to train alongside them against their enemies. People had chose to be Spartans, but remained as they wanted to be. As Azeroth's original heroes.
The same doctor from a month ago watches the simulation from the board. The Spartan and Marine recruits face themselves against the Burning Legion and the Alliance in a mosh pit of powerful enemies at the Legion's camp.
The soldiers' own minds were their leaders. Directing themselves or others to follow a suitable command. It works with them in chaotic situations where the soldiers would attempt to use their brains to guide others in the right path and the other person would do the same. There was no chain of command in these situations, only the instinct of the squad members were the only things that kept them alive. But Azeroth's ancient enemies were more intelligent and greater in numbers and strength.
But the doctor would prove it otherwise. As long as the Spartans doesn't intend on dying or losing to them. They would get the mission done, no matter what the odds that they face on this planet.
She had kept watching them navigate the forests of Northrend while the Alliance and the Legion caught the small teams of Marines in the crossfire. They were carrying colonial civilians away from a downed ship to the extraction point, and this was the last test. Which can lasts for hours, and they can run out of ammo at any moment. Luckly for them. The other hero types were able to restore lost ammo, but they need to focus to cast any spell, or to take cover at a moment's notice. Thanks to the volume of enemy fire and the magnitude of enemy forces.
One of the mages had created a temporary shield to block some amounts of arrows and magic, but it ran out quickly. At least they found a cave to hide themselves. Sadly. It would take hours for the fighting to die down. But they weren't that much harmed at all, soon enough. They shall pass their trial.
Unknown Ruins, The Mountains of Hyjal.
Back on Azeroth. A lost ruin lies within the depths of Hyjal, but it was recently been discovered by the Argent Crusade to execute their enemies. This time, it was something that they will regret greatly.
A Dragon was being put under a pillar of sunlight, infused with ancient alien technology within his scales. He was burned when the light struck him at full power, until he was disintegrated completely straight after. All of the Argent Crusade shouted in victory. Because of the Dragon's own affiliation was of the Dark, but it was the Aspect of the Storm. For some reason, one of the Wardens who were there had started to act strange.
Suddenly, one of the more powerful Illidari Revenants had appeared from a disguised person. Then the Death Knights had popped up out of nowhere and started to work with each other and attack the Crusaders.
(Good evening, Sameria) - An unknown voice invades the Warden's own mind. This was relating to either of the Death Knights or the Demon Hunters to this fight, she wasn't even moving.
(Today, you shall know the sins of your own organization, and your redemption is right in front of you. These Wardens had imprisoned our kind for ages, just to sacrifice everything to fight off the Legion so many times. These 'heroes' are a mere mockery, imprisoning great warriors because of their own powers that were simply 'unacceptable'. Now you will bring forward their punishment, but only if you are able to trust us) - The voice had used visions of the Warden's past.
All of them were simply imprisoning Death Knights and the Illidari. For them, they were speaking the truth for the Wardens to help them to ward off the Legion. Except they were blinded by ignorance. And they must be punished utterly, until they're serving this hive mind or to be exterminated completely.
She was heartbroken, and shows her own betrayal by using a large portion of her magic to teleport the Dark Dragon's ashes away from the Argent Crusade. Then she sided with the Illidari and vanished completely along with them. No one knows what happened to her, and now the Wardens must deal with a runaway rogue. But this would lead them all to their demise.
The Sunless World - (Unknown Dimension)
When the knights and the hunters had returned to their homes, it was in a cloud of ancient ash that darkened the entire dimension. This was the rumored Sunless World, a place ravaged by many ancient alien civilizations, the Burning Legion and the Old Gods. The dark energies that remained on this planet had expanded into a black hole and swallowed other nearby planets and merged with this one. An infinitely expanding realm that remains darkened.
The Illidari, Warlocks and the Death Knights had joined allies and made their new home in this realm. Nearly no one has reached to this place and survived the devouring abyss that creeps along the ground. They were an exception, because of their powers. They were allowed to cross into the regular universe and the Sunless World.
Sameria remained silent, and the voice returned once more.
(These people were some of your relatives who were risen from the grave or they chose the power of Fel to sacrifice their fame or public acceptance to aid themselves against their common enemy) - The Voice sounded different, it was nearly sounding like Illidan.
(The Legion threatens our world at every moment they have, but the 'heroes' don't understand our strife to contain this ancient enemy. They were afraid at the wrong thing, and we were put in the fearful minds of many inhabitants of Azeroth. They all went to imprison us, thinking we won't be controlled by anyone else. This was all a mistake they made)
(And you join one of our problematic factions. These Wardens have the spine to imprison us, for we have a simple answer. Mortal power never works against the Legion alone, and ours will never be effective enough to stop them. Both powers must join to crush their advance. For now, you must drink from the Fountains of the Cataclysm. Soon after, find me in the sanctum. You will begin your mission) - The voice fades away, the three fountains form in front of her. They harbor dark energies from within. Anyone drinking from those become powerful with the elements that can destroy anything on Azeroth.
The green fountain represented mostly the element of death, disease and the demons within, the blue represented the powers of many souls. Enough to summon the shades of many warriors to fight off many enemies. The red fountain represented war, wrath and destruction. It manipulated the Earth to be used against enemies with remarkably destructive force. Causing even smaller earthquakes to shatter the ground beneath them.
She drank from each one, and her armor changed color every time. It stopped to a light blue color on her armor, and can now yield souls to her affected glaive and greatsword. It even formed a chain hook at her waist.
The door opens further ahead. Revealing a vortex of souls, and three statues which represented an ancient Orc Warlock, the next was Illidan Stormrage, and the last one was Arthas, the Lich King himself. Their souls were collected once more and placed within the Sunless World. This vortex was a fusion of deadly warriors and kings, and each one of them had spread to other members. They worked together with the hive mind to complete their goals. She had became a part of this, except she was more powerful than the others.
(Now that you've obtained the powers of Cataclysm. I will now direct your anger and confusion to your new enemies. The Wardens remained proud of their false justice, enslaving many of our own for sacrificing everything they had to stop the Legion. Some of these people were long-dead relatives who received the worst from the Wardens) - The mind of Arthas spoke to her to direct her emotions against the Wardens.
(This is your job to use our powers to destroy and desecrate everything that they had, and if you can't kill anyone of these wretched beings, break them down and morph them to serve us to atone their murderous and bigoted nature)
(But along with this. You need to dispose Sylvanas, for she is using our forces to spread her plague and ruin our name. We were made to ward off the Burning Legion, not to recklessly destroy anything as we please. You must dismantle the Forsaken's plague machines and uproot Sylvanas. But be warned, she has new allies, and you can still die as a mortal would. But this shouldn't concern you, the Forsaken must be punished for their arrogance)
(May you suffer well, Lady Sameria) - He sends her out of the Sunless World to now hunt for Sylvanas, infused with the many souls that can bring the ruin of a civilization.
