>>98206817>Not understanding the Council of Nikea and why it was done.
The Librarium is called the fucking Libararium because it was a structured designed by Magnus to collect knowledge and for the Legions to be the instrament to collect this knowledge.
Specifically, Warp Knowledge. The Emperor had no qualms against Psykers or Battle Psykers, but he 100% did not like the idea of Psykers dabbling into shit they do not know.
This is where the Rune Priests of the Space Wolves differ, because unlike every other Legion, the Space Wolves did not accept the terms of the Liberarium, and refused to both give and take the knowledge Magnus provided.
Magnus spread the idea of Warp Sorcery and the Knowledge of Warp Sorcery, Rune Priests specifically are not Warp Sorcerers and instead channel the powers of Fenris itself.
Big E visited Fenris himself, Big E would have known if the World was some kind of Daemon, Big E would not have allowed Rune Priests to be exempt.
Fact is Rune Priests are actually VERY GOOD at combating Chaos.
The White Scars would have been exempt too if the Wind Spirits were not found to be Daemons due to the corrupting influence of Magnus's Liberarium.
Every idea of Magnus's was literally "Let's huff Chaos shit"
