Admiral Valinov continued pushing deeper and deeper into Heretek space, crushing the enemy at Aldebaran.
Meanwhile, Sethano decreed that a strike force consisting of two fleets was to jump to the Propus System in the former T’au Empire, now almost entirely under Necron control. If the Necrons were able to complete their extermination of the T’au, they would turn to the Imperium next, as it was still prosecuting its wars against the Hereteks and Tzeentchians. As a purely practical matter, ensuring the continued survival of the T’au would mean that the Necrons would be forced to commit more resources to the front, and that was in the Imperium’s best interest for now.
This was especially important considering how many worlds the Necron Dynasties now ruled, a vast empire in the galactic north.
It would also buy the Imperium time to conduct repairs on the wrecked Attack Moon in the Euros System.
Individual Necron fleets were more powerful than those the Imperium had deployed, so careful planning would be required to draw them out or slip past them as both Imperial Battlfleets moved toward the Wenkwort System, home to a former T’au sector capital.
Meanwhile, efforts had begun to chart a path to the worlds hidden in the chaotic Galactic Core.
Back on the Southern front, Admiral Valinov won yet another overwhelming victory against the foul Hereteks.
All was proceeding as Sethano had foreseen. Besides sharing many of the Emperor’s memories since her childhood, she had always possessed a degree of prescience, whether she had mistaken it as intuition, or glimpsed it as her terrible purpose, to unite the galaxy under Imperial rule no matter how much suffering it would cause, or the compunctions she would have to leave behind to do so. But her powers were ever growing, and she could now extend a measure of the gift - and curse - of prescience to her loyal admirals with a specialized interface, replacing some of the functions of the the Navigators of old, whose bloodlines had gone all but extinct.
The war against the Tzeentchians moved to Segementum Pacificus. Moving to head off Tzeentchian expansion, the Astra Militarum, backed up Psyker Legions, consisting of those who had honed their psychic powers far beyond typical humans, invaded the primitive world of Opis I.
The xenos were not humanity’s friends. However, simply purging them was inefficient and wasteful when they could be forced to toil for the Imperium’s benefit in the rich mines of the world that was no longer theirs, bringing in raw materials critical for the success of the Final Crusade. She did not feel the sort of compunction that had once troubled her when she consigned the Nu-Baol to nourish the Imperium as livestock. If anything, their fate was kind next to the one she had inflicted upon the plantoids. They should be grateful that they had been granted an indefinite stay of execution, as long as they behaved themselves and recognized the Imperium as their rightful overlord.
She did, of course, reserve the right to exterminate the lot of them should they rebel against her rule. But for now, the priority was for the Astra Militarum to turn the planet into a Fortress World, from which the Imperium could project its power into the rest of the Segmentum.
Explorator Fleets finally reached the supermassive black hole at the center of the galaxy, Sagittarius A*. While it had once been far quieter in galactic history, it was now ablaze, inflamed by the presence of warp rifts and the Chaotic energies that seethed from them.
Sethano noted the news as she prepared for battle.
“Lady Commander! It is an honor!” Inquisitor Karamazov said.
"The enemy capital lies before us, Inquisitor,” Sethano said, flanked by a small detachment from the Adeptus Custodes. While they were first and foremost the guardians and companions of the Emperor, as the Imperial Regent, who spoke with the authority of the Emperor, she was one of the few other individuals in the galaxy entitled to their protection. “Kill every last Heretek on the planet and cleanse this world of Chaos’s taint. I leave the details of operational command to you."
“And... if I may ask... what will you be doing during the battle, my Lady?"
Sethano removed the Blade of the Huntress from its sheathe at her side, an ancient relic that hummed with barely contained psionic power... much like her own.
“Leading the charge."
Imperial morale soared when the troops saw Lady Sethano on the front lines. And while she may have been 112 years old, her psychic power bolstered her physical strength, endurance, and reaction time tremendously, letting her fight as if she was a much younger woman in her prime.
The Hereteks never really stood a chance.
Sethano continued to fight in each battle as one Heretek planet was cleansed after another. She noted with interest though a report of a xenos civilization discovered in the Galactic Core. They were not suited to hard labor, but were technically inclined and adapted to arid environments... while being far more nimble than mere servitors.
“Send a battalion of the Astra Militarum to Rayunstrisryn I,” she ordered. “I have use for these xenos called the Ewoxulans. I will grant them my Sanction to live in indentured servitude to those who would benefit from their skills, though they must remain under trusted Imperial supervision at all times. Make an example of any who resist."
On the Necron front, the task force had reached the Wenkwort System. The Paradise World of P’thun became a war zone as Inquisitor Vivica Telux, Inquisitor Karamazov’s younger protege, and a fanatic loyalist to the Lady Commander, led the assault against the soulless machines.
Finally, in 302M43, the last Heretek world fell to the Lady Commander and Inquisitor Karamazov’s forces, after Admiral Valinov demolished the Heretek’s orbital defenses in the Cursa System.
It was a resounding victory against Chaos.
And the Hereteks would only be the first to fall.
