Doctrine
The Rite House is the oldest surviving religious institution on Geba and the official faith of the imperial capital. Its teaching holds that He Who Allows is the supreme cosmic authority and that the empire Vaer'karesh established is the direct expression of that authority on the planet. The unification of the five nations, the standardization of language, the conquest of Thazvaar, the liberation of Berinu, the assimilation of Jeyrha, all of it is framed as permitted and endorsed by He Who Allows through the imperial line.
What the Rite House does not teach is where the problems begin. It does not acknowledge what the Velcrith did to the planet. It does not teach that they restructured a brown dwarf into a habitable world or that Velcrith Vessels channeled knowledge that shaped the entire course of civilization. The Velcrith are either absent from the narrative or treated as a deviation from the order that He Who Allows established. The Seraveth fare worse. They are not addressed at all. They do not appear in Rite House teaching, doctrine, or liturgy. An entire category of beings that merge with humans in alignment with the Infinite simply does not exist within the institution that claims to be the final word on He Who Allows.
Influence
For most of recorded history the Rite House held enormous religious and political authority. Its priestesses and administrators operated as an extension of imperial governance during the eras of conquest and expansion, lending spiritual weight to military campaigns and territorial absorption. Leaving before ordination was not something people did. Eira Vey's departure was the exception, permitted only because Prince Raeth stood behind it, and what she produced afterward became the alternative the Rite House could not answer.
In the modern era the Rite House retains its official position in Karesh but its reach has contracted. Veyan Thought is now the most widely accepted understanding of He Who Allows on the planet, and it was built by the woman who walked out of the Rite House's doors. The institution did not lose a doctrinal argument. It lost a factual one. When evidence from real Vessels became available through Eira Vey's writings, the Rite House could not incorporate it without dismantling the imperial bias that was its entire reason for existing. It chose the bias. The population chose the evidence.
Modern Position
The Rite House continues to operate in the capital and maintains chapters in major cities across the Geba continent. It remains the faith of the administrative class and retains the ceremonial functions tied to imperial tradition. For the billions who follow Veyan Thought or the Saodeh or who reject the framework entirely, the Rite House is an artifact of an era when the empire needed a god that agreed with it. It still teaches that god. The rest of the planet moved on.
