Eternal Father

"The ignorance of a man blinded to truth, and the grief of a child who loved a corpse. A repugnant combination."
The Dark Lord's blade was knock aside, the broken weapon tumbling in the air for a brief moment before quickly righting itself. It danced through the air, pirouetting and circling around for another strike. Again and again, relentless and hungry. It had tasted so many deaths before it's sundering, and it yearned to replenish all that had been lost. The whimpers and shrill screams of a thousand multitudes wailed from behind the blade's metallic surface, the length etched with a myriad of blasphemous Sith runes that radiated with a dark power all their own.
From below, the earth's maw opened wide and thick roots reached up to take hold of the Dark Lord's body. His eyes only spared the vegetation a ephemeral glance, His gaze already settling back on the Jedi Master. Leaping from His flesh came gouts of bright azure flame, incandescent rays of fiery energy that voraciously sought out life and matter. They were bound to the Dark Lord's will, entirely reliant on His power for their existence. They chewed through organic matter easily, but so too did they consume inorganic matter; metal, stone, glass, even things that would normally not be afflicted by the ravages of the inferno.
Beyond that, and perhaps most insidiously, was their devouring of the bonds that connected the Force with the material universe. It did not simply disrupt the influence of a Force-user over the world, it erased it wherever the flame touched. In it's wake were colorless streaks of entropy, instances where the connection had been severed so grotesquely it stained the universe with it's perversion. It was painful to look at for too long, and the keen disturbance that rippled outward from where the crude edges of entropy met the rest of the universe was far too unsettling.
Darth Carnifex moved forward, almost a spectral mirage than a being of flesh and blood. "Don't you understand, Alexandra? Yasha Cadera died on Mandalore, I devoured her soul myself. What then has shared your bed all these years, if not a corpse?"
Suddenly He was between her and Manu, His movements so sudden and abrupt that the light bouncing off where He'd previously was hadn't even had time to fully dissipate; that fleeting version of the Dark Lord slowly fading as the photons scattered. His hand came down, wreathed in the power of the Dark Side to be as strong and as cutting as any well-honed blade. Forgoing a traditional weapon, He sought to cleave her from shoulder to groin with His bare hand.
"Go join the grub in oblivion."
