@supertinyking@ShadowVentusValentus hesitated, as he realized another psychic presence was nearby. This force seemed to be decreasing the power of Chaos, but in order to be able to function within the Warp Storm, this psyker would need to be highly trained. Even Imperial Psykers were usually annihilated by the force of the Warp Storm, blowing themselves to bits. Either that, or this individual would have to be a powerful servant of Chaos, most likely of Tzeench, masquerading as assistance. He remained suspicious, but he would not intervene with the psychic link until it turned out to be an issue. He was not averse to outside assistance, especially now.
"Move out! Guard your minds and bodies, assume everything that moves and isn't your comrades wants to kill you. Shoot on sight." Marching out of the building, Valentus emerged into what appeared to be a crowded city street. Except the crowds were mutants, and the city seemed to be on fire. So it was tuesday again. "Cleanse this world for the Emperor! Fight for your lives, for those that don't make it to the bunker will be dead before the day is done!" Valentus opened fire with his Storm Bolter, the double barreled weapon tearing through the enemy like they were made of tissue paper.Those few abominations that made their way into melee he simply punched to death, not deigning to use the power of the Daemonhammer against them. His flanks were meanwhile covered by the Dominion Soldiers, who were finally able to use their weapons against something that would give a shit.
However, even as Valentus made his way through the city, he felt another presence meddling with the mind of his former ally. Forming a psionic link, and granting power. It was intrusive, and the fact that such a thing had been allowed to happen was heresy by itself. Had he not been balls-deep in heresy right now, he would have hunted down the origin of this meddlesome presence, as it was he simply destroyed it's influence on his vulnerable friend's mind. "An open mind is as a fortress, with it's gates unbarred and unguarded. In the warp storm, trust nothing, not even your own thoughts. The forces of Chaos are devious in their subtelty." He could sense more-less where this being was, that chose to mess with the group. He decided to send a fairly simply message, as the being would find themselves being suddenly telekinetically bitch-slapped.
Of course, the entire effort was most likely pointless. The last time a Warp Storm of this severity had ravaged the universe, it had lasted almost a hundred years. This entire planet, and everything on it, would be cleansed of all pure life long before the Warp Storm abated, and there was nothing Valentus could do about it. The Forces of Chaos would soon arrive, his fallen brethren fighting alongside the Daemonic abominations. But he was a warrior of faith, a soldier in the infinite armies of the God Emperor. He would lead those around him to victory, no matter how unlikely, and die only atop the corpses of his enemies.
Little did he know that he was heading towards the very same bunker that Rex was currently assaulting.
