The ''''''''Nikaea''' is a planet widely known for the '''[[Council of Nikaea]]''' on which was a great convocation called by the [[Emperor]], several [[Primarchs]] and high ranking [[Adepts]] of the [[AdministratumMankind]] met one year after shortly before the [[Ullanor CrusadeHorus Heresy]], to decide discuss the fate use of psychic powers in the [[Psykers]] and [[SorceryImperium]] , particularly within the [[ImperiumAdeptus Astartes|Legions Astartes]].''''' {{Planets|Map=Galaxy map unknown.jpg|Planetary Image=Unknown.jpg|Name=Nikaea|Segmentum=Unknown|Sector=Unknown|Subsector=Unknown|System=Unknown|Population=Unknown|Affiliation=Unknown|Class=Dead World|Tithe Grade=Aptus Non}}

==Origins==
There was an increasing concern as the Great Crusade progressed as to the specific use of the physic powers that were manifesting in the human population. Many individuals with psychic powers were put to use as [[Astropaths]] and [[Navigators]]. Some time after the start of the [[Great Crusade]], three [[Primarch]]s - [[Magnus|Magnus the Red]] of the [[Thousand Sons]], [[Sanguinius]] of the [[Blood Angels]], and [[Jaghatai Khan]] of the [[White Scars]] - proposed that Librarius Departments should be formed in the Legions to harness the latent psychic powers that were beginning to manifest in some Astartes. Initially, the Emperor sanctioned the experiments; however, as he withdrew from the fighting of the crusade, many called for him to pass judgment on whether the experiment should continue. More and more often the [[Imperial Guard|Imperial Army]] and [[Space Marines]] would make planetfall only to find that the populace thralls to [[Ruinous Powers|mysterious powers]]. These people were essentially slave cults who would resist the forces of the Emperor with sorcerous powers granted them by [[Daemons|daemonic beings]] from across the [[Warp]] - powers that were very similar to those used by Magnus and his Thousand Sons.
=The Planet Nikaea= Nikaea was a world that, during the time of the [[Great Crusade]], was a new world or a world in it's geological infancy. Clouds obscured the surface while tectonic movement created constant pyroclastic eruptions and storms across the planet, rendering navigation in the system and on the planet's surface next to impossible. The only way to navigate to the Nikaea system and the planet below was through the use of a beacon of incandescent light visible only to those with "aether-sight"<sup>1</sup>. The council chambers were created on Nikaea within a hollowed out volcano.<sup>2</sup> =Origins= There was an increasing concern as the Great Crusade progressed as to the specific use of the physic powers that were manifesting in the human population.

Also known as After both sides had an opportunity to speak on the '''''Edict topic of Nikaea'''''using the aether, the Emperor stood and made his decree.
==The Emperor's Decision==Ultimately, in what would become known as the Edict of Nikaea, the [[Emperor]] decreed that the Legions would disband their Librarius Departments, and all Librarians would return to the battle companies and never employ their physic psychic powers. He believed that men were incapable of using the [[warp]] while not succumbing to its "darker temptations". He did however sanction the use of [[Astropaths]] and [[Navigators]] as without them the [[Imperium]] would be impossible to rule over. He also gave one final warning:
'''''"Woe betide he who ignores my warning or breaks faith with me. He shall be my enemy, and I will visit such destruction upon him and all his followers that, until the end of all things, he shall rue the day he turned from my light."''''' <sup>4</sup>
==Attendees==
*<sup></sup> ''denotes individuals who gave testimony at the Council''
It should be noted that there were several individuals in attendance whose identity remains hidden. This is due to the use of ''''"falsehoods'''' " that hid the identities of the person, or persons concealed behind them. [[The Emperor]] order ordered that falsehoods be used so that no individuals' testimony would "be corrupted by fear of those who's eyes are upon him."<sup>5</sup> It is implied by [[Ahzek Ahriman]] of the [[Thousand Sons]] that these individuals behind the falsehoods are in fact, Primarchs from other Legions; this is due to his ability to feel the power emanating from behind the falsehoods.
