Board Thread:Warhammer 40k General Discussion/@comment-2253300-20130211000751

Now I generally consider myself to be well read on 40k lore. I also consider myself to have a good idea about how the lore works within the setting. Despite this there is a single question that I have found myself unable to answer. The question is a rather important one in regards to understanding the lives of the Imperial citezenry, and for those of you who, like myself, like to write some fanfiction every so often poses an obastacle.

How much does the Imperial public know about the Horus Heresy? now from what I have read nobody in the modern day Imperium knows everything that happened during the Horus Heresy with the exception of Big E himself. Furthermore it is widely understood that the Imperium harshly keeps knowledge of Chaos from the general population in order to decrees the likelyhood of Chaotic taint taking root.

My issue with understanding this is with the teachings of the Imperial Cult. If I am not mistaken it is understood by the Imperial populace that the Emperor sacrificed himsefl, suffering grievous wounds in order to preserve his subjects, but do the people of the Imperium know how he came to be in his state? Were they told of the Hellish rebellion that occured? Are they aware that this rebellion was lead by Primarchs, or even that these Traitor Primarchs existed? Perhaps they were told that the Emperor recieved his wounds when dealing with some foul evil.

I can't be sure. So I submit my question to you, my fellow 40k fanatics and experts. How much does the average Imperial citezen know about the Horus Heresy?
