Lord Anargo has a strict policy against the practice of any religion other than the Imperial Cult in an unacculturated form. As such no local observances, practices or organic introduction of a specifically Anargan practice of the Imperium Cult is present and, as such, the influence of the adeptus ministorum on the ‘hearts and minds’ of the local population is minimised. Any non-standard practise is considered cult activity and, as such, penalised as heresy by the local adeptus arbites. The Imperial adeptus arbites take a somewhat less rigid stance to acculturated forms of the Imperial Cult, more so specifically because as off-worlders they often share these ‘non-standard’ beliefs. Off-worlders are, however, permitted to perform acculturated forms of the Imperial cult in the various extraterritorial zones of the world, most specifically the starports and the Imperial Conclave.

Anargo’s approach to religion is an outgrowth of the Anargan Theocracy, a pro-Vandire government which came to power out of the acculturated beliefs of the Anargan people during the early Age of the Imperium and the Age of Strife. The pre-Age of Strife religion was a derivative sector of an archaic millennial religion which believed that a saviour would arrive and lead the Anargans to greatness. With the formation of the adeptus ministorum following the Emperor’s ascension to the Golden Throne, the Anargan religion was easily acculturated into one of the standard variants of the Imperial Cult: the Emperor was the messiah who had come and once again sacrificed himself for his people, his Saints and Angels the Primarchs and blessed warriors and heroes of the adeptus astartes and all those warriors who served and worshipped him with all their heart. As the Age of Imperium was broken by the Horus Heresy, non-standard ideas were slowly integrated into the Anargan religion and the power that was only theirs in part was, by the Age of Apostasy, assumed in total: the Anargan Theocracy that was born with the coming of the Imperium grew to maturity under the cloak of Vandire.

It was not until the Gaian revolt of 362.M39 that the Anargan Theocracy was gradually put down and the soon-to-be-raised Imperial Commander censored the specific variation of the Anargan faith as ‘heretical’. After suffering for a millennia the people were ony too willing to move away from the teachings of the Anagan Theocracy and the dogmatic variations from the older ways that had been such an integral part of their lives.

The specific religious beliefs of Anargo are therefore those of the Imperium. With that said, however, the presence of the adeptus ministorum is reduced over many developed worlds of the Imperium. While the administrative districts are essentially the same as the previous diocesal and parish boundaries, there is no translation over to the adeptus ministorum. Rather, the administrative districts are divided into parishes and the former dioceses integrated into much larger entities. While nominally this might seem to increase the power of individual Cardinals of the adeptus ministorum, diocesal power is maintained as an administrative feature with the Cardinal merely being the ‘priest’ of the largest Church to the Emperor of Mankind. It is a very fine and minor point, but one that is traditional to Anargo and which has often brought the position of Lord Anargo into question with the priesthood of Dorvastor.
