Eternal Father
<"Thou needn't cry aloud, thou art chosen.">
His fingers traced small ternions across bare flesh, smoke rising where the digit pressed into skin. In its wake was left raw meat, the outer layers of skin burned away by mere touch. The individual to which the skin belonged to pulled hard against the restraints around their wrists and ankles, sheets of metal torn from the walls and tightly bent around each limb until movement was fully impeded. No matter how much they struggled, the bonds would not budge; and would even grow tighter over time, blood seeping out where the metal dug into their skin.
Demiurge was an innately ritualistic creature, drawn to symbolism and ornate ceremony. One could consider him the most devoutly religious of the pair, with Carnifex focusing more on the material world and its material needs. In a way, Demiurge was obsessed with the material as well, but with how to ascend it entirely. He believed that pain was the key, that through pain the abandonment of flesh could be achieved. Already, the pair primarily existed as formless energy, but without an avatar of flesh to act as a conduit for their power they could do little to affect the world around them.
He wanted to overcome that limitation, to pass beyond the barrier and achieve full incorporeal might. To this end, he subjected countless to immense suffering. His latest victim squirmed as Demiurge drew another symbol into his flesh, the stench of sizzling skin tantalizing to the Dark Lord's finely tuned senses. Conversation between them had quickly died out, as Demiurge refused to speak to them in anything other than ur-Kittât, which they could not understand. Even if they could, Demiurge's crypticism would only confuse them, for they were not as enlightened as he.
Suddenly, Demiurge perked his head to one side. <"It seems we are not as alone as I had believed."> Demiurge then slid his finger along the man's lips, fusing them together as though they had been welded shut. With his screams now muffled, Demiurge felt confident in leaving his canvas alone for a moment to investigate.
