Fiction:Attero Dominatus/Picking up the Pieces

Masterplan
Gravius Gnissenkrassau was in charge of the Tyranny counteroffensive, and had pooled a mind boggling 50 million Tyranny ships into a force that was meant to be able to with ease take the slaves down. 100 million Mark 2s Gravius thought, supported by the Tyranny, was more than enough to be able to crush entire civilizations in a massive show of force of the Drakodominatus Tyranny. The capital ships, capable of standing to practically any ship in the First Gigauquadrant and winning, were pooled into a few strategic black holes which were to be used as launching points from which they couldn't be seen. It did not take a genius to figure out that the slaves were finally going on an offensive against Tyranny controlled worlds, and Gravius, a genius of IQ in excess of 1200, easily predicted the exact systems the slaves were going to attack, in which he made it purposefully easy for the slaves to take over.

The plan was that once the slaves had taken over the worlds, at some cost, and deployed ground troops to rescue slaves, that before they could know about conversion into biodrones, the Dominatus would arrive en force with there massive and advanced fleet that outnumbered the slaves by quite a bit, where 50 million of the Mark 2s would go on a massive path of destruction of conquest among the slave planets to turn them into biodrones and to attack the other nuisances to the Tyranny while 50 million of the other Mark 2s would go to the planets and engage the slaves in what was to be a series of incredibly one sided pitched battles where the Dominatus would utterly crush the slave forces in a display of their raw power, intimidating everybody else.

Gravius had complete and utter faith in his plan, he had never lost a battle before, and his Mark 2s were powerful enough to go toe to toe with DCP ships of the same class. He merely faced slaves, revolting worms who had to be crushed and turned into biodrones. The massive armada gathered at the black holes where they awaited the strikes, where the Tyranny would finally emerge triumphant.

Steamroller
The first attacks started in the Milky Way, where the Tyranny had lost the most amount of colonies where the slaves were attacking with what was generally commandeered Mark 1 ships, which according to an official transmission from the Draconid Imperium, they were classes as being able to go one on one with even the ships of the Draconid Imperium given their size. These slaves had the plan in which they would simultaneously attack all across a wide front on a campaign to take over the infrastructure of the Tyranny in the Milky Way, a plan they had absolute faith in. They however did not know much of the Dominatus counter plan, and had no idea what they were getting into.

The first attacks entered into a few worlds of the Tyranny only known by name to some, and unknown to most Dominatus generally, except the Dominatus knew of each planet in depth for this operation. Everything was intricately laid out, the biodrones hidden beneath the equator and the slaves would not know the consequences of invading the world. The first attacks started relatively gently, as the slaves launched probing attacks which they followed with massive strikes on Sentinel Class battlestations, where the Dominatus themselves weakened the shields in order to hasten the battle.

The slaves soon had space dominance and elated by this turn of events began landing troops onto the worlds where excited by the thrill of victory, they surged while only minimal amounts of Myrmidons and overseers were deployed against them, and soon enough, as they surged across the worlds, they knew that they were going to win, however, right as they found out the worlds infrastructure had been destroyed before and that the slaves were biodrones, the Tyranny fleet appeared over the planets and outnumbering and outclassing the slave ships, utterly and completely obliterated their forces with their system shattering firepower, as they used their baleful weaponry against less advanced and less numerous ships.

The slaves in the Milky Way were much too late to realize their folly, as Interdictor Class Dreadnaughts also prevented their hyperdrives from working to any extent, and they were trapped in one sided battles. This was accompanied by the Dominatus landing their own land forces in tandem with orbital bombardment on the slave armies, which were now forced into horrendous last stands in which they were all massacred or turned into biodrones, and the ichor and gore of their bodies fertilized the barren lands of the worlds.

The Tyranny ships also broke out across the slave colonies in a massive steamroller, completely and utterly destroying whatever resistance the slaves managed to put up with sheer brute force, and soon they were going through the slave colonies like a hot knife through butter. Gravius plan was working to his expectations, though anomalies happened in Andromeda.

Mark 2 Might
Mortrig Malevon was not in a pleasant mood, not a good one at all. He had been posted as a fleet commander in order to help support the attacks on the slaves, but he felt another urge, the genocide of a complete borderline tier 3 empire, the Federal Vilerg Council. Mortrig had under his command a million ships, and he diverted them from the slave campaign in order to completely subjugate the Federal Vilerg Council. He marshalled the ships and through a sheer display of force, marched through the Federal Vilerg Council's territory as an unstoppable wave, destroying the vastly outnumbered and vastly outclassed Vilerg ships with a massive flood of Mark 2s.

Worlds burned and fleets were destroyed as the scintillating fire of Gatling Hyperlasers went through their worlds, utterly destroying them and turning all survivors into biodrones. The massive blitzkrieg also came without warning, as the Vilerg had just been in friendly talks with the Dominatus. In minutes, the Vilerg were being wiped out by the vastly more powerful and numerous Mark 2s, and suddenly all there worlds were Dominatus.

The final world was one in the Milky Way, like all of their other colonies, and Mortrig himself led the ground assault, possessed by an inhuman rage, and he went to the palace of the Vilerg and with his bare hands killed the entire council. And with the dead who were not turned into biodrones by his order, displayed a message of gore, and across the burning planet, from space could be read a message, scrawled out in bodies, it read Ameius.
