Iron Pupil

In the brutalist citadel of Panoptis, a look can kill. Literally. The society is rigidly divided by "The Sight." The ruling Seers possess a weaponized gaze capable of paralyzing or burning their enemies, while the underclass, the "Veiled, " are forced to wear heavy iron blindfolds to survive, never allowed to look upon their masters. Sable is a Burnisher. A slave tasked with polishing the black iron of the citadel, she hides a dangerous secret: "Mirror-Eyes." A rare mutation has turned her irises into polished silver, allowing her not just to resist Ocular Magic, but to reflect it.
She keeps her head down, invisible and safe in the dark. Torin is the Lord Inquisitor, known as "The Basilisk." His gaze is so monstrously powerful that it causes spontaneous cardiac arrest in anyone he meets. Isolated behind a heavy iron visor, he is the most feared man in the empire, yet the most touch-starved. He has not looked another human being in the eye for fifteen years without ending their life.
The dynamic changes forever when Sable loses her blindfold during a raid. Torin looks at her, expecting death. Instead, his lethal magic bounces off her silver eyes, and for the first time in his life, someone survives his gaze. Captivated by the impossibility of her existence, Torin claims her. He locks her in his private chambers not for punishment, but for a singular, desperate need: she is the only creature in the world he can actually look at.
But in a city built on surveillance, their connection is a dangerous flaw in the design. He is the eye that kills. She is the mirror that saves. And he will burn the world just to keep watching her.
