I: General features of Nibenese religion
Vibrant, colourful and exotic, the Nibenese East is often perplexing and bizarre to the outsider’s gaze. The innumerable traditions and rituals that permeate the life of its people can seem just as impenetrable as the jungle that surrounds them; from the rice fields and riverside villages to the sprawling island metropolis of the Empire's majestic capital, all of settled Nibenay is inextricably wound up in the supernal. And yet so different their customs are from those of their western kin or other Nine-worshipping cultures of Tamriel that no aspect of life in the Heartland is more often misunderstood than the religious practices of the Nibenese.
It is a popular saying amongst the Colovians that there are more cults in the Nibenay than there live people along the banks of the great river. Many West Cyrodils share the attitude that their eastern counterparts are lacking in faith; that it is because they only half-heartedly exalt the Divines that they are immoral and of inferior spirit compared to the steadfast West. In turn, the Nibenese consider the Colovians too rigid, passionless and unimaginative in their veneration. They find little to adore about confining themselves to a single portrayal of each of the Nine and only the Nine, existing far above the mundane and accessible only through prayer directly addressing them. Just as hard as it is for the West to understand their mysticism, the East cannot grasp how priests can speak to the gods while removed from everyday life and confined to churches and monasteries; the numinous exists in everything for the Heartlanders, its facets far too many to be appreciated only by prayer.
While an outsider can thus misinterpret the Nibenese in a similar manner that Colovians often do, it would be a grave mistake to believe they are a people given to insincere worship, religious cynicism or even heresy. The world is not divided into the religious and the mundane in the East; one bleeds excessively into the other, everyday acts granted a degree of sanctity by their association with the Divines, who are in turn often worshiped not only by word, but by action as well. The gods are thought infinite and unknowable to mortals, certainly far too vast and complex entities to be known only through vows and contemplation, which is likened to trying to know a room only by the view through the keyhole.
This is the same argument used by the Imperial Cult to justify the existence of cults that have only the weakest of associations with the official religion, but which cannot be fought and driven out by virtue of being too deeply entrenched in society. The religion of the Nibenay is, after all, an entity perhaps just as complex as the gods that now stand at its centre. Ayleids, the Cyrodils’ Nedic ancestors, Nords, the Alessian Order and Tsaesci have all played a part in the creation of the sprawling network of cults that can be found in some form even in the most backwards corner of the Heartland; some had a role more prominent than others, yet all were sooner or later absorbed into this grand tapestry, becoming individual threads that are at the same time woven together with one another and nigh impossible to separate. It can hardly be said today which aspects of the Nine worshipped today began as Alessian saints or what the Order adopted from the rites as ancient as the slavery of Man of which we have only vague and unreliable knowledge.
When the time came for the Nine Divines to enter this shapeless, many-layered entity, it was obvious they could not do so and remain unchanged. So it is that the Divines of the Nibenay have become beings just as vast and multi-faceted, puzzles composed of many pieces. Each aspect is almost a god unto itself, worshiped separately from others and from the entirety that it contributes to. Often, the lines between the gods’ respective domains blur, their various forms passing into one another’s spheres; where a Colovian might not see why a farmer would pray particularly to Talos, he, as the guardian of the crops from both enemy and beast, is a popular figure in the rural areas of the East. Likewise, cavalrymen revere Kynareth as the mother of horses, for it is she who blesses or curses her children and can thus decide a rider’s fate. The Nibenese perceive neither these, nor any other similar examples as oddities; nor do they take issue with certain cults placing aspects of the gods in marriage, while another cult venerates one of those same deities in wedlock with a third. All that is accepted as the effect of the Divines’ infinity and placed in an almost Alessian light by the quite widespread belief that the gods cannot all be endless without, on some level, being one.
Such a great house of the gods as outlined above cannot be easily tended and warrants an equally vast priesthood - the priestly caste of the Nibenay is perhaps the most extensive of all those who worship the Nine. It is not only – and not even the most prominently – those priests which are part of the hierarchy of the Imperial Cult as it is known elsewhere. The line between the clergy and the various semi-autonomous colleges that tend the more prominent cults associated with one of the Divines is rather blurry and the authority of the High Priests over them laxer than it is within the confines of the regular churches.
These colleges are often seen by the Nibenese themselves as the most important of the clerics, for it is they who perform many important rituals and provide certain social services. Two of the three great cults of Mara alone – those of the All-Mother and Mara the Bride – serve a purpose that can hardly be replaced. It is the maids of the All-Mother that tend orphanages in the Nibenay, seeking to draw nearer to the Mother Goddess through experiencing motherhood themselves by raising those who have no parents but Mara. And no Nibenese wedding could be imagined without the joining steps and the applications of marital markings upon the couple’s skin, both acts that are carried out by the bridesmaids; indeed, they are the iconic priestesses of Mara ingrained into the imaginations of most Eastern Cyrodils, with their light, almost fluid silk dresses of vibrant blue fluttering in the waxing and waning passions of the joining dance. Even the poorest of newlyweds scraqe together enough for a sacrifice to the cult to bless their wedlock, a matter of immense importance for their families' honours and the new family's sanctity.
And then there is the Scholarium of Julianos, with its many internal colleges each charged with the advancement and passing on of a particular science; the college of the Ferrymen, found in even the smaller towns of the Nibenay, with their grim duty to the Dragon-Ferry, to see off the dead on the final voyage through the great river in their paper hako skiffs; the coryphees of Dibella, who add one more step to their yearly dance of things past for every month that passes. Those, along with several other major colleges of the Nine, shall be discussed at greater length later.
Beyond the larger colleges, there is a plethora of various other cults of the Divines with their own dedicated priesthoods, more secluded from society, such as the Akatosh-related but influenced by both Nordic and Altmer tradition cult of Time Unhalting, whose priests spend much of their life alone, dwelling on the unstoppable nature of time and living each day the same as the last in an effort to trick the Time God into stopping his relentless march forwards. Smaller cults like this are even less attached to the greater structure of the Churches; many similar ones exist that do not have a dedicated body of priests at all, the highest positions within them held by people with secular occupations – like the more specialised cults of Zenithar. This does not prevent the tenders of these cults from being entrusted with secrets of ritual or the rites from being recognized without question as valid, much to the abhorrence of Colovians.
There exist also the cults that have no associations with the Church of the Nine and yet have their own priests. The dominant among those is clearly the cult of Ancestor-Moth, the moth priests and the moths themselves still retaining a central role in the burial rites of the nobility; however, numerous smaller cults exist, like those of heroic historical figures, particularly past emperors. A number of smaller mythic heroes are gathered together in the Cult of Heroes, very popular among the nobility, many of whom claim to descend from one of these figures. These groups which exist outside the Imperial Cult shall be the first that I will describe in some detail.
