The two days that followed were not a lapse in time, but a slow descent into a specialized, clinical hell. Inside the windowless laboratory, the concept of morning and evening had vanished, replaced only by the wet, rattling percussion of Solvayne's breathing and the soft, rhythmic sob of Nyxelle's voice. She was chanting—low, melodic incantations that her body could no longer afford to speak, each syllable dragging a price from her marrow.
Nyxelle's hands, which had once glowed with the warm, golden radiance of a summer sunrise, were now a horrifying sight. The light pulsing from her palms had turned a sickly, flickering pale green—the color of swamp gas or a candle guttering out in a drafty tomb.
"Just a little more," she whispered to the empty air, her voice cracking. "Just one more layer."
Anasil's cruelty was methodical. He provided them with nothing but thin, watery broth—a liquid insult devoid of the caloric supplements and mana-rich proteins required for high-level restoration magic. To heal Solvayne, Nyxelle was forced to burn her own life force as fuel. She was the wick, and her magic was the flame eating her alive. For nine hours every night, she knelt over her sister, her small frame trembling with such violence that her teeth turned the inside of her lip to ribbons.
"Please... please close," Nyxelle whimpered, her vision blurring as she pressed her palms against a deep, purple hematoma on Solvayne's ribs.
Underneath the silk rags of her shift, Nyxelle's own skin felt paper-thin, stretched taut over bones that protruded like the very skeletons preserved in Anasil's jars. Every time she pushed mana into Solvayne, she felt a phantom sensation of her own organs shriveling.
"Nyxelle... stop," a voice wheezed.
Solvayne's eyes fluttered open, glassy and unfocused. The massive bruise that had once blackened her face had faded to a jaundiced, sickly yellow, but her insides remained a shattered battlefield. She could feel the heat of Nyxelle's magic—a heat that felt like it was being stolen from a dying hearth.
"You're... you're turning gray," Solvayne managed, her voice a ghost of itself. "Your hair... it's falling out. Stop. You'll die."
"I don't care," Nyxelle sobbed, a thick drop of cold sweat hitting Solvayne's cheek. "I don't care about the hair or the skin. Why? Why did you do it, Solvayne? You knew he was looking for a reason. You knew he'd enjoy breaking you!"
Solvayne reached up, her fingers shaking with the effort. She brushed a brittle, translucent strand of hair from her younger sister's face, her touch lighter than a feather. A weak, bloody smile touched her cracked lips.
"It's what... an elder sister... would do," she whispered. "I'm the shield. You're the heart. We... we have to keep the heart beating."
The effort of the sentence was the final straw. Solvayne's hand fell limp, striking the cold stone floor with a dull thud. Her eyes rolled back into her head as she fainted once more, claimed by the sheer agony of the mending process.
The heavy laboratory door clicked open with the sharp, final sound of a guillotine blade hitting the block. Lord Anasil stepped in, his presence immediately tainting the room. He smelled of expensive sandalwood cologne and the fresh, mocking scent of the outdoors—a world the sisters were no longer permitted to inhabit.
He stood there for a moment, silhouetted against the bright hall light, watching the half-dead child on the floor and the trembling, skeletal girl hovering over her. He didn't look angry. He looked like a connoisseur viewing a masterpiece.
"Still at it?" Anasil asked, his voice airy and light, as if he were discussing the weather at tea.
He strolled across the room, the click of his heels sounding like hammer strikes. He stopped by Solvayne's head and nudged her limp leg with the tip of his polished, calfskin boot.
"She's quite resilient, I'll give her that," he mused. "Most children her age would have succumbed to the internal hemorrhaging by the second hour. You've done a commendable job of keeping her 'pretty' for the gala, Nyxelle. I was worried I'd have to present a lumpy sack of meat to the Auditor."
Nyxelle looked up at him, her eyes so sunken and rimmed with dark shadows that she looked like a corpse herself. "She needs food. Real food. Not water. Please, Uncle... she won't survive the night without more mana. Her heart... it's skipping. I can feel it."
Anasil leaned down, his shadow stretching long and distorted across the laboratory floor, swallowing both sisters. He reached out and tucked a lock of Nyxelle's hair behind her ear. His fingers were freezing, feeling more like porcelain than flesh.
"Life is about choices, Nyxelle," he whispered, his smile sharpening into something truly vile. "You are working so hard to save her. You are giving her your youth, your beauty, your very blood. But look at you. You are becoming... hollowed out. A husk."
He leaned in closer, his voice dropping to a conspiratorial murmur that made the very air in the room feel oily and stagnant.
"Let us make a wager, little bird. A game to pass the time before the guests arrive. If your 'elder sister' fails to wake up... if she dies before the gala begins... I will be in a difficult position. I will need a new project to ensure the lineage continues. Since the 'set' will be broken, I will have no use for a niece."
He let his hand linger on her shoulder, his grip tightening just enough to cause the bone to creak.
"If she dies, you will no longer be my niece. You will be my vessel. You will bear my child. We shall see if the next generation can be bred with a bit more... durability than you two failures."
Nyxelle's heart stopped. The air left her lungs as the sheer, stomach-turning horror of his words sank into her mind. It wasn't just a threat; it was a promise. She looked at the glass incubators surrounding them, seeing her own terrified, ghostly reflection multiplied a dozen times over.
Anasil stood up, smoothing his waistcoat with a self-satisfied hum. He looked down at them one last time, his eyes gleaming with a dark, predatory hunger.
"Better keep those hands glowing, little bird," he called back over his shoulder as he walked toward the door. "The stakes have never been higher. Don't let the fire go out."
The door slammed shut, leaving Nyxelle alone in the dark with her dying sister and a choice that felt like a death sentence.
