Skill Groups: Adeptus Astartes, Adeptus Mechanicus, Archeotech, the Black Library, Daemonology, Heresy, the Inquisition, Mutants, Psykers, the Traitor Legions, the Warp and Xenos
Forbidden Lore skills represent knowledge usually hidden, veiled, or proscribed by an organisation or society. Mere possession of this knowledge may cause difficulties for those not associated with the group in question. Excessive knowledge of the hidden truths of the Traitor Legions, for example, can be decidedly bad for one’s health for those outside (or even inside) the Adeptus Astartes. A successful Forbidden Lore Test indicates the character recalls basic information about the subject. The GM reveals additional information as appropriate to the Degree of Success on the roll.
Adeptus Astartes: Extensive knowledge of the practices, organisation, and homeworlds of the Imperial Space Marines and their Chapters, including hints and rumours of their myriad of secret rituals and methods of recruitment and training.
Adeptus Mechanicus: An in-depth understanding of followers of the Machine God, including such things as their rituals, observances, common beliefs, core philosophies, and specific knowledge of the Universal Laws.
Archeotech: Knowledge of the great, lost tech devices of past times and clues to their mysterious functions and purposes.
The Black Library: Secret knowledge concerning the Black Library, its forbidden contents, horrific guardians, and the unspeakable xenos that toil within its confines.
Daemonology: The crawling information about some of the most infamous warp entities and their twisted physical manifestations.
Heresy: Wisdom concerning acts and practices deemed heretical by the Imperium, the most contemptible heretics of history, and their acts.
The Inquisition: An understanding of the secretive organisation of the Imperium, its common tenets, and famous Inquisitors.
Mutants: The study of stable and unstable mutations within humanity, their cancerous development over time, and some of the studies and books on the topic.
Psykers: Skill in identifying psykers, the physical effects of their powers, the danger they cause, and the general extent of their capabilities.
The Traitor Legions: The secrets of the lost Space Marine Legions, their names, and the sad tale of their fall from grace.
The Warp: An understanding of the energy of the warp, its interaction and interrelation with realspace, and how its tides and eddies affect travel between the stars.
Xenos: Knowledge of the minor and major alien species known to the Imperium, the threat they pose, and their general appearance.
Skill Use: Free Action… although the consequences of knowing such things can last a lifetime.
