The Death Worship, known to it's followers as Sekêrrayîtsa, in the Ieseleu-speaking world as Seheuhediice, and to the Lákhar as the Og'oie Zrim, the great heresy, is a very controversial religious movement originating around 400 terran years ago. It is the only monotheistic faith on Suenu, and the only one with holy scriptures. It is also unique in that it has an exclusively female clergy, even though men can fill other roles within the religious hierarchy. It was probably the first example of a cosmopolitan, universal religious movement, open to converts from all ethnic, economic, class and national backgrounds.
Sangal, the small continent north of the equatorial woods region, located to the north-east of the Netegeniu, was originally populated by neolithic hunter-gatherers and sea fishermen, numbering no more than 6000 inhabitants. Their culture is now mostly assimilated, save for archeologic remains, as a consequence of dramatic migration around the year -100. The huge migratory movement of -100, that involved some 400.000 people over a period of thirty years, came from the mainland, specifically from the Lákhar peoples. The Sanga language is probably the language, or at least one of the languages, spoken by the native Sangalese peoples before the time of the migration. Local folklore both from Sangal and the Lákhar nations tell the story of king Azrgam [sanga. âsarrakâme] who disagreed with the preaching of a very successful local prophet from the eastern coast of the peninsula called Seyiri [sanga. seyirri]. The prophet and his following were the object of systematic religious persecution for months, and in response Seyiri called his followers on an exodus to the promised lands beyond the sea, to the island now known as Sangal.
In reality, the huge migration that took place from around -100 to -70 had deeply-rooted economic and demographic causes: not only was the economy of many Lákhar kindgoms had been destabilized by excessive minting and consecutive inflation, but a grave epidemic of a virulent and very fast-acting disease, lethal on around 6% of infected cases within days, had sown panic throughout the region. In fact Sangal wasn't just populated by Lákhar-speaking immigrants, but also Ieseleu and even some Yi families from the south got on the trading ships as refugees and were dropped off in the ports of Sangal.
A key strategic move by the prophet Seyirri, who had become not only the religious but also the political leader of the fledling Sanga nation, was to enforce, even against the advice of his own retinue, a policy of openness to immigrants and newcomers. This "everyone's welcome" policy, that has been more or less carried on by the Sanga religious authorities after his death, flies in the face of traditional Lákhar values. For the Lákharzasc, migration is a sign of disrespect towards one's motherland, birthplace, family, and community. In times of deep economic and social upheaval, such as the early years of the Sekêrrayîtsa movement, however, the open borders policy brings in many refugees that flee from various undesirable situations. The historical reasons why the newly-formed immigrant society that formed around the ports of Sangal adopted the native Sanga language, spoken by what was now an ethnic minority within their own home territories: one distinct possibility is that Seyirri himself was from Sangal, or had some bonds with the local peoples. This would also explain the negligible resistance of the native Sangalese peoples the whole movement.
