The inhabitans of the Cradle System are no strangers to religion. The Progenitors' existence in the distant past was marked by vast wars between rivalling religions. The end of the First Dark Age of Industry caused this to escalate further as many now-forgotten nations collapsed into theocracies and then barbarism, the latter either in spite of or because of religion.
With the coming of the Nerakk Empire, the Progenitor-Descendants adopted many of the creeds of their new Nerakk masters. When the Nerakk left the Cradle System and the Hrukan Oligarchy emerged, much effort was done towards creating a new distinct Hruka culture, as independent and different as possible from those of the Nerakk. Whether that has succeeded or not is up to debate, but in the field of theology it has meant that the dominant Hruka religions are the ones which came into being shortly after the eruption of the Great Two-Front War which crippled the Nerakk Empire.
The current religious currents of Hruka society have much in common, and ironically the shared tenets only serve to highlight the different schisms. This makes Hrukan religion extremely confusing since noone is completely sure exactly what means what and a great deal of them never openly question their own definitions or motivations. To add to the mess which the Hruka religions resemble to an outsider, the many movements have many sub-schools and sub-movements which intertwine with each other in a truly strange web. Individual thinkers and/or groups of thinkers have connections and relations to other groups which have splintered off from movements whose ideologies are all but completely alien to the thinkers mentioned first in this sentence, and tiny disagreements have caused almost violent schisms which never have been forgiven.
Add to this that the "spiritual landscape" of the Hruka is perhaps that where things are the least black/white and you have something very difficult to comprehend. Even the highest thinkers of the Hruka do not know exactly whether their proclaimed enemies just misunderstood tiny details or disagree with them vehemently on all points.
To begin with, Hruka religions are not as much religions as they are philosophies with adherents with practically religious loyalty to their respective schools. The overall effect in their society, though, is much like that of religion. Whereas the religions we know usually are built upon the assumed existence of deities, the only thing that all Hruka religions agree on are the complete and assured existence of any sort of goddesses or gods. What they then build upon is the consequence of the non-existence of gods.
The two major schools of thought and their many sub-groups are:
Seih-Avinlak teaches that since gods do not exist, we mortals must strive to produce gods of some sort. Exactly how is the source of the internal schisms within this school.
- Seih-Avinlak rhekra Hruk Eg-Hra takes this literally and attempts to make gods of mortals through means relating to natural science, as the Hruk Eg-Hra find that all which cannot be measured and weighted do not exist. These are often found disagreeing on exact what the definition of godhood is, producing further schisms within this. The Hruk Eg-Hra Nukar-Vhul have been conducting expensive, but well-funded, experiments in genetic engineering (both mechanical and selective breeding) to produce increasingly intelligent and physically strong prodigal Hruka - as such, they count among them the brightest minds of the Hruka. The Hruk Eg-Hra Kahok-Sa are infamous for their other approach to becoming gods as they upload their minds to mechanical bodies and modify their computerized minds. Despite their few numbers, they are amongst the most influental and powerful of the Hruka sects. Mention must also be given to the Hruk Eg-Hra Svankar-Hrai-Katak, who basically want to produce their gods by crossbreeding with Faeries taking Hruka forms, something which has not happened yet.
- Seih-Avinlak rhekra Hruk Gir-Sa-Hra believes that the bit about becoming gods is a metaphor for striving higher and producing a society of such splendour that all else pale in comparison. Much of this movement overlaps with Hnur-Avinkor, but parts of it considers itself a wholly different beast such as Hruk Gir-Sa-Hra Sak-Vhul-Knar who define the divine mindset as considering oneself of godly importance next to others - in other words, Hruk Gir-Sa-Hra Sak-Vhul-Knar is that everyone should only apply any sort of morals to oneself and not respect anyone else. Hruk Gir-Sa-Hra Sak-Vhul-Knar overlaps at times with Hruk Eg-Hra, but it is not known to which an extent as Sak-Vhul-Knar thinkers usually solve their arguments with knifefights rather than actual discussions. This particular submovement is nonetheless popular amongst the most ruthless and scheming of the Hruka nobility. Other Gir-Sa-Hra sects include Hruk Gir-Sa-Hra Avak-Nath-Svahok, who believe in lifestyles planned in great detail through mathemathical calculations in order to produce perfection, Hruk Gir-Sa-Hra Nukar-Ji-Sa who recommend that the Hruka nobility should strive towards only produce children of prodigal intelligence (though they have no hopes of producing literally god-like people) and the strange mysticism practised by Hruk Gir-Sa-Hra Eg-Avin-Kha and its splinter group Hruk Gir-Sa-Hra Eg-Avin-Sikul which places great importance upon psychic powers. Hruk Gir-Sa-Hra Eg-Avin-Kha shows some inspiration from Veglyr religion, and as such it is a new subschool since few Veglyr ever receive permission to even set foot upon Dragim, and in those cases only ambassadors and Cosmic Fleet officers on political visits.
- Hnur-Avinkor rhekhra Hruk Sik-Vuharak-Re is similar to a mirror image of Hruk Eg-Hra in that they give no attention to that which cannot be measured or weighed. Most of them are very hostile to the very concept of art as distinct from decoration, and the Hruk Sik-Vuharak-Re Kel-Reh-Sua-Nak sub-movement even refused to believe in the existence of extradimensionals until one of their adherents witnessed with his own eyes Hadariel's meeting with the Hrukan Oligarchy's highest governing council. The major philosophical schism within Hruk Sik-Vuharak-Re is on the relationship between logic and emotion - the Hruk Sik-Vuharak-Re Hnakka-Suln subschool teaches the abandonment of all emotions, the Hruk Sik-Vuharak-Re Sil-Saruun find the differences between logic and emotions nonexistent (for which they are often considered an outlaw movement by the Hnakka-Suln) and the Hruk Sik-Vuharak-Re Sil-Siak-Arhi who advocate a balance between logic and emotion similar to that symbolized by the yin-yang. A growing group within these, however, the Hruk Sik-Vuharak-Re Kel-Vahish operate with a trichotomy between logic, emotion and a form of affect which they call Vahish.
- Hnur-Avinkor rhekhra Hruk Gvi-Hrennak-Sha believes that godlike entities can exist but do not and should not. What it means to prevent deities from existing, though, is unclear. The Gvi-Hrennak-Sha Hnur-Hrai use this as an excuse for taking an extremely hostile stance towards extradimensionals, both Faeries and Mala'akim, something which in practice amounts to violently attacking adherents to Hruk Eg-Hra Svankar-Hrai-Katak, extreme paranoia (even by Hrukan standards) about who actually is a Hruka and who actually is a Faerie and picketing the occassional negotiation with an extradimensional. The much bigger Gvi-Hrennak-Sha Hnur-Khas-Nukar movement and its many ideological subschisms, though, want extensive laws regulating genetic engineering, computer development and a ban on mind-uploading. A few of these even argue in favour of a technological regression. Finally, the Hruk Gvi-Hrennak-Sha Gir-Kaiv-Rihx movement, which borders on actually being of the Hruk Sik-Vuharak-Re persuasion, interpretate "godhood" as allegorical and warn against megalomania and associated states of mind. They have attracted much ire for calling for an end to the legendary isolationism which the Hrukan Oligarchy has maintained forever.
