Eternal Father
They were called the Black Cells.
Metaphorically and literally, they symbolized the darkest reaches one could ever be subjected to. The very walls of the prison were made from metal blackened to the point where no light could reflect off of it's surface. One could not tell where the walls ended and the ceiling and floors began. Prisoners were thrown into these darkened cells, made to suffer a seemingly endless nothingness. They would find that no matter how far they moved they could never reach the walls, even though they knew the room was not that large when they had been thrown in.
Time would not obey them either, for in their perception years stretched on in complete darkness while only hours passed beyond the walls of their prison. In such total isolation, the mind often succumbed to madness. When a mind was broken in such a way, it could be sifted through and dissected without the redoubts of mental defenses. Those that were discarded to the Black Cells emerged broken people, their minds shattered by the infinity of shadows. And when their gaolers had their fill, they were discarded.
She had only been within a Black Cell for a few hours at most, but in her mind it had been years. Hunger clawed at her belly, thirst strangled her throat, but she did not die. Her body did not wither, she did not age. Her hair never grew, she felt no other bodily compulsion other than an intense hunger and thirst. When they came for her again, the light from the exterior corridor was as blinding as the brightest star. They dragged her from the cell and out into the wider complex, passing by great temples to pain and suffering inflicted upon the enemies of her captors. Today, she would be spared the worst of it.
Where they left her, she could not know -- only that it was a room smothered in smoke and shadow. Her bindings had been removed, the metal having dug into the skin of her wrists and ankles during her captivity. She was left to linger in her misery for a time, before she could sense another in her midst. This was a different shadow than the one she endured in the cell, it was far more potent.
Worst of all, it was a living darkness.
She would only see His outline initially, a smudge against the indistinct smoke that bordered her perception. But, in an instant, it all bled away into normality. She found herself in a plain gray room, no larger than a modest living quarter, but still not alone. He was there with her, His towering presence casting a dire gloom over her. She knew His name, she knew His face, but that knowledge imparted onto her by her master and her comrades paled in comparison to being near Him. He radiated a malice so acute that her skin reacted with phantom sensations, as though it were crawling atop her muscles. An unnatural chill crept up her spine, her every instinct struggling between fight or flight, like she were left naked and unarmed before a great and terrible beast; one that would tear her to ribbons in a heartbeat.
"They call you Revna Sharr, do they not?" His voice was like the death-throes of a primordial world, the glacial annihilation of whole continents as tectonics shifted and collapsed in on one another. She would know in an instant that this was the voice of a being who had ordered the death of trillions, the bane of all life. There was no warmth, no solace to be found in familiar tones, only the harsh bite of each syllable as they crept through her inner ear. To hearken to Him was to hearken to obliteration, to keenly know the articulation of cruelty made manifest.
To gaze upon Him was to court the inevitability of an event horizon, to know certain death was imminent and unavoidable. Every inch was cut the image of a conqueror, a butcher, a tyrant. His shoulders were broad, body sculpted for war. A plain tunic of black cloth hung down across His torso, the edges embroidered with phrases of Sith scripture in the blasphemous tongue of ur-Kittât. He bore no weapon, for He did not require one. He could kill her a word if He wanted to, every action potentially lethal.
All of His being demanded submission, and her own body fought to obey that sensation; as though to not commit yourself to His will was wrong and grotesque.
"Your master makes very large waves for a creature so small, Revna Sharr. I want to hear your thoughts on his recent actions." Though she felt no compulsion through the Force, it was as if His very voice compelled her to do as He asked. "For the sins of the master are often laid upon the brow of the apprentice, are they not?"
