===003.M31: Council of Nikaea===
{{Main|Council of Nikaea (Hektor Heresy)}}

After [[Shakya Vardhana]] brought news to the Emperor of the [[Black Augurs]] apparently using of horrific sorcery, the legitimacy of the Librarium was called into question.  Notables of the Imperium were gathered on the world of Nikaea to determine whether sorcery could be used at all without presenting a dire threat to mankind.  The Council also served as a ''de facto'' trial of [[The Voidwatcher]]. Many of the Primarchs spoke on the matter, but the final decision was the Emperor's.  The Librariums were disbanded and their members sent into ordinary squads, under strict instructions not to make use of their powers.  Malcador the Sigilite ordered that each Legion follow the example of [[Void Angels|Fifth Legion]] and establish an order of '''Tribunes''' within their ranks to police the Emperor's decision.
