The Steel Inquisitives

Maddened enforcers with steel eyes who burn metal to crush dissent and hunt Mistborn rebels.

The Steel Inquisitives are a terrifying order of enforcers created by the Lord Ruler to maintain his absolute rule over Scadrial. Originally human men and women, they undergo a brutal ritual that pierces their eyes with steel needles, granting them immense Allomantic power while stripping away their sanity and humanity.

Lore & Background

The psychological toll is immediate and severe. Inquisitives lose their capacity for empathy, logic, and self-preservation, becoming ravenous predators driven solely by the instinct to hunt those who wield Allomancy or defy the Lord Ruler. They are often depicted as twitching, weeping figures with steel eyes that glow faintly, constantly burning metal in a state of manic exertion. Despite their madness, they remain highly effective soldiers, serving as the primary threat to the rebellion throughout the history of the Final Empire.

In Their Own Story

The street was empty save for the rain, slick and cold against the cobblestones. Then came the sound: a wet, rhythmic tearing of metal. He turned, his heart hammering against ribs that felt too fragile. Standing at the end of the alley was a figure in dark robes, head tilted unnaturally. Two points of dull steel glowed where eyes should have been. The air suddenly grew heavy with the taste of copper and ozone as the Inquisitive began to burn Steel. With a sickening crunch, the man's own belt buckle tore loose from his waist, yanked violently by an invisible hand. Before he could scream, the metal in his bones was pushed, twisting him like wet clay into a broken heap.

Reader's Guide

The Steel Inquisitives represent the ultimate perversion of Allomancy within the Final Empire. Created by the Lord Ruler to hunt down Mistborn and suppress rebellion, they are former humans transformed through a ritual involving steel needles driven into their eyes. This transformation grants them an overwhelming ability to burn Steel, allowing them to push on any metal present in a living body. This makes them terrifyingly effective at disarming opponents or crushing internal organs without touching them. However, the power of Preservation that fuels this ability drives them mad, leaving them as mindless, weeping monsters. While they serve as the primary antagonists during the reign of the Final Empire, their existence highlights the Lord Ruler's cruelty and his reliance on fear. Their eventual defeat marks a turning point in the history of Scadrial, signaling the end of an era where magic was used solely for oppression.
