Referencing Bureau of Shadows File 44-K — The Sacred Ledger

Furnace Catechist
On those who preach the Chain of Cause to men who know perfectly well why the furnace roars — and why neither party will say so aloud.
The Bureau of Doctrine's industrial clergy — stationed in every bastion powerhouse to preach that fire burns by divine permission rather than chemistry. Three thousand four hundred Catechists, two factions, and one question no one will authorise an answer to.
