The Necroteuch

The Necroteuch is a proscribed tome of heretical lore whose custody is disputed in Eisenhorn’s Helican investigations. It is classed among the literature restricted under Imperial interdiction, its contents held to concern practices and knowledge forbidden to the unshriven mind.

Within the case record associated with Inquisitor Gregor Eisenhorn, the tome surfaces as an object of pursuit by multiple factions operating in the Helican sub-sector, its exact provenance and full contents not consistently established across the available accounts. Its presence is linked to the location catalogued as KCX-1288, where competing claims to the text are recorded, and to a subsequent auto-seance incident within the sub-sector whose full circumstances and consequences remain disputed in later tradition. Custody of the work is described as having passed between investigators, collectors and proscribed cults, reflecting the broader contest between Imperial authority and heretical interests that characterises the period.

The Necroteuch is treated in these accounts as emblematic of the risks attending forbidden knowledge within the Inquisition’s purview: a text whose study is sanctioned only under strict controls, and whose uncontrolled circulation is regarded as a hazard to those who possess or consult it. Its standing rests less on any single documented act than on its recurring role as a contested object within the wider narrative of Eisenhorn’s career, illustrating the tension between preservation of dangerous lore for study and the imperative of its suppression.
