This is a crossover between Warhammer 40K and StarGate, StarWars, StarCraft. I always wanted a new race for Warhammer 40K. The new race is an amalgamation of the Galactic Empire of StarWars, Goa'uld Empire of StarGate, and the Terran and Protoss from StarCraft. I will be using the Clone Wars era for the StarWars, and post Ori-invasion for the Goa'uld, and units from both StarCraft and StarCraft 2. I don't own anything from Warhammer 40K, StarGate, StarWars, StarCraft. I am just writing it for fun.

Void Keeper Wars - Warhammer 40K

Prologue

"Well?"

The voice was quiet but strong. The voice came from a naked man, standing tall at about two metres and long dark brown hair that reached down to his waist, staring at the stars outside the massive window. The window was easily ten metres high and fifty metres wide, and outside was the vastness of the empty space, where the stars could barely be seen. Another voice answered his question. It was soft gentle voice but it was genderless. It was a neutral voice. A computer's voice.

"We are in 41th century AD in the alternate universe 1C4294.03A-94, variance 94 of a 'Warhammer Universe'. At this time in this reality, the human race has sprawled across over three hundred eighty million planets in the galaxy under the name of 'Imperium of Man' under the command of their 'God Emperor', and there are over a million worlds in territorial conflict with them. Other races within this galaxy include the Eldar, Necrons, Tau, Ork and an amalgamation of human and demons called the Chaos."

The man merely continued to watch the stars.

"I already know of Warhammer. Never really played it. Haven't I come to this universe before?"

The computer answered again.

"Yes, master. 7834 years ago, personal time. You ran several simulations introducing elements from other alternate universes into the Warhammer Universe."

The man smiled slightly.

"I love a good crossover. What did I do?"

"You have introduced Goa'uld from 1B6352.49D-55 StarGate Universe."

"The result?"

"The first attempt failed because the Goa'uld Empire was far smaller than the other empires. The second attempt was set with Goa'uld's Jaffa army to match the Tau Empire. However, the conflict between the Goa'uld's hyperdrives disturbed Immetarium and the corruption of Jaffa and the Goa'ulds ultimately led to the corruption of the entire Imperium of Man by the Chaos within two thousand years. The third and the successful attempt were simulated with the Goa'uld hyperdrive not entering the Immetarium and beginning with the territory and army matching the Tau Empire. Also, you have set a single leader of the Goa'uld and gave them the Kull Warriors and several technologies from the StarGate universe."

"Very good. Let's play again. Hmmm. I think I want a mixture of some kind this time. Let's play from the very beginning. Prepare for Time Warp. Get me to about fifteen million years in the past from now."

"Yes, master. Preparing for Time Warp."

The man turned and walked away.

Chapter 1: Origins of War

For a long time the Lord Marshal Joshua Hegalis of the Imperial Guard was stationed on Terra in charge of administrative duties. Finally, he got back his command. A meagre force of one million but it would do. He was to be made the Governor Militant of a planet at the edge of the Imperium. An obscure planet called Cafalas IV, colonised several thousand years ago but still at the edge of the Imperium.

At the time, the forces of Chaos began to appear in the region. This sudden movement of the Chaos forces surprised the Imperium but the administrative procedures were extremely slow and the Lord Commander Militants of the Imperial Guards decided to send Joshua to garrison the planet and defend it. The travel through the Warp was perilous but he and his forces finally arrived. His ships descended upon the lush green world.

As the Governor Militant, Joshua quickly set up his base of operation in the capital city of Galvan in the northern continent. The presiding 'governor' of the planet was quickly set aside to make way for the militarisation of the planet. Joshua fully intended to make his mark upon the history of the Imperium and all those who serve the God Emperor will know his devotion.

Within fifty years, the once green agrarian world turned into a world of barracks, airfield, factories and armament storages. Joshua called in every favour he could to turn Cafalas IV into a military planet. Vast foundries were fed by the nearby asteroid field and the metal turned into machines of war. The Machine Cult was very delighted and supported Joshua with various technologies and resources to build up a full scale machine world bent on producing troops and military hardware.

The city of Galvan grew one hundred twenty times in size during that time and it held one hundred eighty million, where as the whole planet only held fifty million by the time Joshua took control of the planet. Now, a powerful planet of population over a billion and a lot of military power, Cafalas IV became the fist of Imperial rule in the region. Joshua also pushed for the colonisation, or reassertion of Imperial rule in the region, expanding the Imperial border and beating back the forces of Chaos from the region. The hierarchy of the Imperial Guards were very pleased.

Now old, the Governor Militant Joshua Hegalis surveyed the city from the tall and mighty fortress citadel. Once a technologically primitive colony of building no higher than three floors have now become a city full of skyscrapers reaching high into the dark sky, and he was pleased. He was old now. An old man, despite the longevity given to him by the Imperium, and he was fading. His name would still be remembered as the Emperor's fist against the forces of Chaos and the Executor of his will in this desolate and barren region of the galaxy.

He had fought many battles since his arrival. The Chaos began to extend their reach into this region of the Imperium and took over many worlds. It was only Joshua's support of unending stream of reinforcements that allowed various regiment of Imperial Guards and the Space Marines to win against the vast hordes of the Chaos. To the Imperium, this sudden push for a rather barren and unpopulated region of the galaxy was strange and curious.

The Space Marines sought some mystical artefacts in the region to no avail. Also, the Chaos somehow changed their tactics in this region. Once infested and entire taken over, they would stop and begin to fortify their positions rather than moving on. Planets after planets, systems after systems fell into their hands though most were valueless. The Space Marines and the Imperial Guards managed to drive off the several important planets and systems, but the new behaviour of the Chaos was baffling at best.

It was as if they were waiting for something. Entrenching themselves to defend against any intrusion. One of the Imperial Guard regiment, along with the support of the Space Marines and the other Orders, assaulted one of the planets conquered by the Chaos, but they only met death by the numerous and unending fields of defensive structures, turrets and a powerful and vast garrison of daemons and Chaos Space Marines. Joshua had sent over three hundred thousand troops and tens of thousands of hardware. None returned.

As the time passed, other races joined in the fray. The Eldar arrived and began to colonise the outlying worlds. Orks and Tau arrived to see what was all the fuss about this region of the galaxy. Even the Necrons arrived in their strange ships and began to eradicate all life from the worlds they landed on. Soon, the region became a powder keg of the galactic powers, and Cafalas IV was the core of the Imperium's territory and war effort.

Strangely enough, various Orders of the Imperium began to arrive in forces, taking up residence in the Cafalas system, and some on Cafalas IV. Something big was going to happen and it would happen here. Governor Military Hegalis felt it. The Orks burnt and pillaged because they were savages, and Tau had no idea, but they arrived just to show that they are also a galactic power. However, the Chaos, the Eldar, the Necrons and the Space Marines knew something. They all fortified their worlds rather than fighting each other vehemently. Something was going to happen.

--

"Governor Militant, Sir! The scouts in the Telerix system report of sightings of strange ships entering the system. The Space Marines and the Battle Sisters have begun a full mobilisation of their assets in the system, sir!"

The governor turned. He still had more fights left in him.

"Very well, lieutenant. If this was what they were waiting for then, I will see to it myself. Call Lieutenant General Derius and the Librarian. Begin the mobilisation of 11th and 12th Regiments."

"Yes, sir!"

Telerix system had only one colonised planet of one hundred million humans. It was near the border with the Eldar and the Imperial presence was rather weak there. Last ten years, the Space Marines began to garrison the Telerix II, while the Eldar, who had entered the system thirty years ago, reinforced their positions. Chaos and Necrons also landed and thus divided the barren planet.

"You have called me, Governor Militant, sir?"

Lieutenant General Jonas Derius, the young Lieutenant General who was favoured by the Joshua himself to succeed him as the Governor Militant, entered chamber. He was wearing his full armour. To honour to his valour in battle, where he saved many Space Marines from a certain and pointless doom, the Space Marines have given Jonas a set of power armour not unlike that of standard Space Marine, but in the colour and decoration of Cafalas Regiments.

"Yes, Lieutenant General Derius. Come! There as been some developments."

Then the door opened once more and the Librarian, in his full armour, entered and gave a short salute to the Governor Militant.

"Governor Militant, you have summoned me?"

"Yes, Librarian Gilmore. There is a situation developing in Telerix system. We must discuss this."

The Librarian was assigned as an attaché to Governor Militant, not only as a show of Space Marine's cooperation to the local Imperial Guards, but to insure that the numerous regiments on Cafalas IV were indeed sent to reinforce the Space Marines, thus avoiding the Kronus Incident where the Blood Ravens and the Governor Militant Lukas Alexander clashed.

"There is nothing more to discuss, Governor Militant. The Space Marines will deal with the situation."

The Librarian spoke curtly. Joshua raised one eyebrow. He growled.

"You forget your place, Librarian. I have been charged in maintaining the Imperial rule in the region and reinforcing the Space Marines is an important duty I, as the Governor Militant, is required to do. Even if the Space Marines refuse my aid, it would be negligence in my part if we do not even discuss this."

The Librarian nodded slightly to acknowledge the Governor's words. Joshua nodded and then spoke. The two guests sat on each side of him, facing each other.

"A moment ago, I have received intelligence that a strange fleet has entered the Telerix system, and the Space Marines and the Battle Sisters, who are charged with Telerix II, are mobilising. That planet has much possibility of turning into a quagmire eating up the Space Marines if we do not intervene. The corrupt traitors to the Imperium are one thing to deal with, but the Eldar and the Necrons in the fray makes this whole situation complex."

The Librarian slammed his fist on the table.

"As I have said, the Space Marines do not require aid. We are the Emperor's Chosen. We will be victorious."

The Governor Militant frowned.

"Why were you not like this during the Colidus campaign? Was it not the Imperial Guards' reinforcement that allowed the continuation of the Purge? If this is some pride thing, then you should be ashamed, Librarian. You would sacrifice your brothers for the sake of your own pride than to accept help and bring victory for the sake of the Emperor. If it is not pride, then tell me the reason for refusing reinforcements in an area where you are in a clearly disadvantageous situation."

The Librarian paused. Emotions of anger and shame appeared on his face for a moment. Then he nodded.

"Very well, Governor Militant Hegalis. If you insist, we will gladly accept your reinforcement. However, remember that your forces will only need to defend the cities."

Joshua nodded.

"I understand. General Derius, I have mobilised 11th and 12th Regiments, take them first and I will send 9th Infantry Regiment and 4th and 5th Armoured Divisions as soon as I can get them ready."

Derius saluted.

"As you command, Governor Militant!"

Joshua nodded.

"Move out, then."

I hope it was fun. Anything to fix, then post a comment, thanks.
