Archival Authority of Argus

The Archival Authority of Argus is a Burning Legion organization presumably based on Argus. They have deemed A Hypothetical Examination of the Legion's Weaknesses to be apocryphal, and the book is currently banned in all Legion-controlled worlds.

Speculation
Since some demons struggle with the ways of the Legion, it is possible the Archival Authority is responsible of the handling of proper propaganda for its troops.
