I did not understand. Not until that moment.
The girl's back arched so violently I heard something crack—a rib, perhaps, or the cartilage between her shoulder blades. Her mouth opened, but no sound came out. Not at first. The light poured through her skin like water through gauze, illuminating her from within so that I could see the branching network of her veins, the shadow of her ribs, the dark knot of her heart hammering behind bone. She was a lantern. A living lantern, lit from the inside, and the light was searching.
It found what it was looking for.
Something dark rose beneath her skin. It moved like smoke trapped under glass—coiling, recoiling, trying desperately toretreat deeper into her body as the light pursued it. Shadow essence. The trace of her heritage, buried so deep she had probably never even known it was there. It writhed along her forearms, pooled in the hollows of her collarbones, gathered at her temples like a bruise forming in real time.
Thenshe screamed.
The sound filled the lecture theater. It bounced off the marble walls and the vaulted ceiling and the forty-three faces that watched with varying degrees of fascination, discomfort, and—in some cases—excitement. It was not a scream of pain exactly, though pain was part of it. It was the sound of something beingripped out. Of a body being forced to betray itself, to vomit up the secret it had carried since conception.
"Note the patterning," Selim said over the screaming, in the same tone he'd use to point out an interesting rock. "The shadow essence surfaces first in the extremities, then migrates toward the core. This indicates a third-generation half-blood—the taint is diluted but present. In a first-generation subject, the emergence would be far more… dramatic."
The girl collapsed to her knees. The chains on her wrists kept her from falling completely, held her suspended at an angle that looked like supplication—or crucifixion. Her head hung forward. Her shift was soaked through with sweat, and where the shadow essence surfaced, the fabric had begun to smoke, tiny holes burning through the gray linen as darkness and light warred across her skin.
Naz was still writing notes. The scratch of her quill was the loudest sound in the room between screams.
I sat very still. My hands were in my lap. My face held the mask. Inside my chest, something had begun to crack—a fissure running through the bedrock of everything I had been taught to believe about mercy and salvation and the divine right of the light to burn.
Selim increased the pressure. I could see his knuckles whitening where his palm met her sternum, and the girl convulsed—full-body convulsions that slammed her against the chains with a sound like wet meat hitting stone. The shadow essence was being forced through her pores now, seeping out of her like black sweat, dripping onto the white marble beneath her knees where it hissed and evaporated on contact.
"The extraction rate accelerates once the core reserves are breached," Selim narrated. "At this point, we could halt the process and the subject would survive, though with significantly reduced?—"
The girl's head snapped up. Her eyes were open, and they were no longer brown. They were black from lid to lid—pure shadow, the last of her tainted heritage flooding to the surface in one desperate surge. She stared directly at me.
Not at Selim. Not at the students. Atme.
Her mouth moved. No sound. But I read the shape of the word on her lips.
Why?
Selim removed his hand. The girl dropped like a puppet cut from its strings, crumpling onto the marble in a heap of gray linen and trembling limbs. The shadow essence still leaked from her skin, slower now, thinning. Her eyes flickered—brown, black, brown again—and then she began to sob. Quiet, broken sobs that weresomehow worse than the screaming because they sounded like something that would never stop.
"Excellent," Selim said. He wiped his palm on a white cloth produced from his belt, the way one might clean a blade after butchering. "As you observed, the detection method is both faster and more comprehensive than traditional testing. Any shadow-taint, regardless of generational dilution, will be identified."
He turned to the class. "The subject will be transferred to the purification wing for full cleansing. Given the depth of her contamination?—"
He saidcontaminationthe way you might sayinfection. As if her blood were a disease. As if she had chosen it.
"—I anticipate the process will be thorough."
Thorough.In the Light Court's careful vocabulary, that meant the cleansing would not stop until every trace of shadow had been burned away. And for a girl whose shadow-taint ran this deep, burning it all away would mean burning away most ofher.
It meant she would die.
The guards reentered. One of them seized the girl under the arms and hauled her upright. Her legs did not hold. She hung between them like a body between pallbearers, and as they dragged her toward the door, something in her seemed to understand whatthoroughmeant too, because she started screaming again—not the animal sound from before but words, actual words, tumbling out of her in a broken stream.
"Please—I didn't know—I didn'tknow—I never used it—I'm loyal—I've served the light my whole life—please?—"
The doors closed behind her. The screaming continued, muffled, fading as they dragged her deeper into the Academy's corridors. Then silence.
Selim clasped his hands.
"For next week, I want three pages on the theoretical applications of detection magic in border enforcement. Dismissed."
Around me, students stood. Benches scraped. Someone laughed about something unrelated. Lord Ediz's son stretched and yawned. Naz capped her inkwell and tucked her notes into a leather satchel with the careful composure of someone who has just attended a lecture on any other subject.
I did not move.
