The void roared its silent symphony around the Imperial fleet as it tore through the warp. Within the polished, ceramite-lined halls of the battle barge Steel Coffin, flagship of the Crimson Fists Chapter detachment, the atmosphere was one of grim anticipation. Two companies of Space Marines, honed for war across a thousand battlefields, moved with a purpose that bordered on ritual. Bolters were meticulously cleaned and blessed, power armor checked and re-checked, vox-channels tested, and prayers to the Emperor offered with unwavering faith.
Captain Valerius Theron, commander of the Crimson Fists' 3rd Company and acting overall commander of the detachment, stood on the bridge of the Steel Coffin. Unlike the stoic Admiral Kaelen, Theron's face bore the scars of countless campaigns, a testament to his chapter's unyielding doctrine. His power armor, a deep, cerulean blue with a crimson gauntlet emblazoned on the right pauldron, hummed faintly with latent energy. He watched the star chart projections, the Golgoth system a distant, ominous glow.
"Reports from the advance scouts are consistent, Captain," his Sergeant, Roric, rumbled, his voice a deep baritone through his helmet's vox-grille. "The xenos entity remains stationary atop the mountain. The shadow constructs maintain their perimeter, no outward expansion detected since the eradication of the Ork WAAAGH!"
Theron grunted, a sound of contemplation. "Too quiet. An enemy that eradicates a Great WAAAGH! with such ease does not simply sit idle. It is either a display of supreme confidence, or it is a predator waiting for its prey to blunder into its lair." He clenched a gauntleted fist. "Either way, we will meet it with the Emperor's fury."
The Space Marines were a different breed from the conventional Imperial forces. Where the Astra Militarum brought overwhelming numbers and the Navy unparalleled firepower, the Astartes brought precision, unmatched combat prowess, and an unshakeable will. Each Crimson Fist was a living weapon, a genetically engineered demigod clad in impregnable armor, wielding weapons that could tear through plasteel and flesh alike. Thirty thousand Guardsmen were a hammer, but five hundred Space Marines were a scalpel and a spear, designed to find the enemy's heart and rip it out.
"Prepare for real-space emergence," Theron ordered, his voice echoing across the bridge. "Battle-brothers of the 3rd and 7th Companies, assume breach positions. We will deploy directly to the surface via Thunderhawks and drop pods. The orbital bombardment will clear a path for the Astra Militarum, but we will be the first to taste the enemy's blood."
Across the fleet, the vast transports carrying the Cadian Shock Troopers and the grim, unyielding Death Korps of Krieg prepared for the brutal reality of planetary assault. Deck officers barked orders, troopers checked their lasguns, and the heavy thrum of starship engines intensified as they approached the system's boundary.
On the bridge of the Imperator Rex, Admiral Kaelen watched the warp coils flare one last time before the lurch of real-space translation. "Golgoth system, all ahead full. Prepare for orbital bombardment. Target grid designated 'Shadowfall Mountain.' Lord Commander Militant, your regiments are cleared for deployment once the initial saturation strike is complete."
Lord Commander Militant Vorkos, observing from a secure channel, simply acknowledged with a curt, metallic "Understood." His forces were ready. They were always ready.
As the fleet emerged from the warp, arrayed in a formidable spearhead, the grim vista of the Golgoth system unfolded before them. A gas giant dominated the void, its swirling storms a kaleidoscope of dangerous beauty. Around it, the lifeless, rocky planet of Golgoth Prime hung like a bruised apple. And there, on its dark surface, visible even from orbit with the fleet's powerful augurs, was the black mountain.
And atop it, utterly unmoving, was the figure.
Even at this immense distance, the sheer, unnerving stillness of the entity was palpable. It seemed to absorb the light, a void in the cosmic tapestry. Around its base, the 'shadows' were like a vast, dark stain on the cracked plains. The sight sent a shiver down the spines of even the most hardened Imperial officers. This was no mere Xenos infestation. This was something new, something that radiated an aura of ancient, terrible power.
"Commence orbital bombardment," Admiral Kaelen commanded, his voice tight. "Concentrate fire on the perimeter of the shadow formations. We will test their resilience."
The colossal battleships and cruisers unleashed their fury. Lances of pure energy, each capable of scouring continents, tore through the void. Macrocannon shells, the size of hab-domes, arced down, trailing fiery contrails. The very air around Golgoth Prime screamed as the Imperial fleet poured its righteous wrath onto the black mountain and its silent army.
The surface of Golgoth Prime erupted in a cataclysm of fire and superheated rock. Continents shuddered, and vast clouds of dust and ash blossomed into the upper atmosphere, momentarily obscuring the target. Yet, as the smoke began to clear, a terrifying truth became apparent to the watching Imperial commanders.
The black mountain still stood. And the figure atop it remained.
The orbital bombardment had scoured the plains, annihilated vast swathes of the terrain, but where the shadow army had been, new shadows were already forming, coalescing from the dust and debris. They were reforming, silent and relentless, as if the very act of destruction only fed their numbers.
Admiral Kaelen's knuckles whitened as he gripped the armrest of his command throne. "Impossible," he breathed. "Bring all augurs to bear. What... what are we facing?"
Inquisitor Lyra Valerius's grim face reappeared on the hololithic. Her voice, usually so controlled, held a note of genuine dread. "It appears, Admiral, that our initial intelligence was gravely underestimated. This entity... it is not merely commanding an army. It is creating one from nothing. A force that thrives on death itself."
On the Steel Coffin, Captain Theron watched the same, terrifying scene unfold. His face was a mask of grim determination. "Then we will give it a death it cannot absorb," he growled. "Thunderhawks, drop pods, prepare for immediate deployment. For the Emperor! For Dorn! Let the storm break!"
