For ten-thousand years, the Symaarian Imperium has been at the forefront of defending this galaxy from the horrors of the universe. For ten-thousand years, it has weathered unspeakable atrocities. For ten-thousand years, it has kept this galaxy from falling apart at the seams.
For ten-thousand years, it has terrorized, slaughtered, and enslaved countless alien species. Justice comes at a cost - that cost is freedom: the freedom to speak out, the freedom to bear arms, the freedom of religion, and in some cases the freedom to live. Those who conformed to Symaarian law were treated like animals and were eventually killed off anyway because of the Imperium's growing xenophobic tendencies. Even though it was not always this way, the Imperium had grown too afraid of its own surroundings and too arrogant to admit it. They blamed it on their mummified "god," calling it the will of the Navigator. The most powerful military empire the Milky Way had ever seen, and it was jumping at its own shadow dancing on the wall. Reform was needed, but the High Lords of Symaar Primus refused to listen to advice - especially advice given from aliens. All ties to the Keresh were severed and supply lines were actively attacked until they ceased to exist between the two. Space Marine Warmasters who had sympathized with the Keresh actually defected from the Imperium and joined with Ravek, bringing their entire Legions with them.
The schism provided just what the Confederate leaders wanted. They needed the Imperium undermanned and confused, a sprained muscle so that the bone underneath could be broken. Atrioch Zephaiah rallied his troops and embarked on a military campaign his ancestors could only have dreamed of...
Space over Holocaust, 1744 galactic standard time
Atrioch watched as the orbital bombardment of the volcanic world's surface went according to plan. The Imperials below him had exhausted all energy in the void shields keeping the foundries and factories from being obliterated under the uncompromising barrage. Meanwhile, any and all ground forces were pushed into bunkers and tunnels lest they become part of the Confederate Navy's gruesome tally. However many died in the initial attacks could not be estimated. Over the course of the siege, the many millions who were caught in the blasts were broken and battered beyond recognition now. Relief efforts had to face the wrath of the Confederate-occupied worlds around Holocaust before actually breaching the blockade around the vital forge world itself. The droid core ships already locked in place on the surfaces of these worlds would be difficult to remove due to their sheer enormity as well as the armies of automatons gradually awakening within them.
The void shields began to crack as a few battleship-class artillery shells plummeted through the breaks and mangled the Imperial production plants desperately hidden behind them. Screaming arcs of fire and metal were all the celebration Confederate engineers needed once the void shields died down and the Symaarians began to retreat into the lava caves.
The Alkha folded his hands behind his back and gave a triumphant nod, knowing he would soon win Holocaust.
