The air inside the Inevitability tasted of ozone and ancient incense. Brother-Captain Arvann Stern stood motionless in the center of the Strategium, his eyes closed, listening to the psychic choir of the ship’s Navigators. They were screaming.

For the Grey Knights of the 66th Citadel, the Warp was not a mystery; it was a battlefield.

"The breach is widening, My Lord," Justiciar Tancred’s voice crackled through the vox, heavy with the weight of his Terminator plate. "The augurs show a tear in the veil near the Mandeville Point. The signature is unmistakable. Khorne."

Stern opened his eyes. They glowed with a soft, silver light. "Then the prophecy of the Libram of Malis is fulfilled. The Bloodthirster Ka’jagga returns."

He stepped toward the center pedestal, where a massive, silver-bound tome lay open. It was the Chapter’s tactical codex—not a mere book of rules, but a living record of every banishment performed since the days of Malcador. He ran a gauntleted hand over the script. The words seemed to shimmer, shifting to reveal the specific rites of dismissal required for this particular foe. As of late 2024 into 2025, Games Workshop

"Prepare the strike force," Stern commanded, his voice gaining the resonance of a cathedral bell. "We do not go to hold the line. We go to erase the stain."

Minutes later, the teleportarium hummed with world-ending energy. Stern and his Paladins stood encased in Aegis armor, their Nemesis force weapons etched with runes that bled white light.

They materialized in a nightmare. The orbital platform was no longer metal and glass; it was a ribcage of bone and rivers of boiling gore. In the center of the carnage stood Ka’jagga, a mountain of fur and brass, swinging a lash that tore through reality itself.

" Stern roared, his psychic presence flaring like a supernova.

The Grey Knights moved with a synchronization that defied mortal training. Tancred and his squad formed a wall of silver, their storm bolters roaring in a rhythmic cadence that shredded the lesser bloodletters. Stern leapt forward, his Halberd trailing silver fire.

He didn't just strike at the beast's physical form; he struck at its essence. Every blow was a syllable of a banishing ritual found within the sacred codex. As the Halberd bit into the Daemon’s throat, Stern channeled the collective willpower of his brothers through the weapon.

"By the Emperor’s light," Stern whispered as the world began to white out, "I cast thee back into the abyss. Be forgotten!"

The explosion of psychic energy silenced the screams. When the light faded, the gore had evaporated. The platform was silent, cold, and empty.

Stern looked down at his gauntlet. A single drop of ichor remained, sizzling against the silver plating before vanishing. He looked at the holographic display of his wrist-mounted tactical feed—a digital reflection of the codex's wisdom. The entry for Ka’jagga pulsed once, then turned grey. Mission complete.
