The first Båtflygtninge to arrive in Solenjord were staunch followers of the Old Faith
, who had held onto their religion despite frequent attempts by Werklanders and Continentals to proselytize among them (Both in the Archipelago and when they took control of territories among followers of the Three). However, unlike the more uncompromising religion of the Three, the religion of the Båtflygtninge was rather more open to the introduction of new gods.
In the uninhabited coastal regions of Solenjord that became Båtjord
, the priests came to the decision that the local spirits were the same as in the Archipelago, as this new homeland was clearly created for them to live in. This idea of it being made for them by their gods was challenged when they met the Plains tribes, who indisputably had different gods from the Båtjorders. This led to debates between several factions of priests, who at the time were not under any sort of overarching controlling umbrella other than worshiping the same gods as each other.
Most of these factions were of the opinion that the gods of the Plains Tribes (And later the Mountain Tribes) were just as real as their own, but they disagreed on whether they were equal, superior, or inferior, and on whether the power of their own gods extended into the lands of the Tribes. The debates raged for many years, and were eventually resolved (though not to the complete satisfaction of everybody) with the decision that the respective gods were more or less equally powerful, though while the Båtjorder gods' power extended even into the valleys of the Mountain Tribes, the Mountain and Plains Tribes' gods' power did not extend into the coastal regions. This last part was one of the only points of universal agreement, even among the consulted priests of the Plains and Mountain Tribes.
In Sletjord in the years after the formation of the Union, a synthesis of the religions of the Båtjorders and of the Plains Tribes began to occur, with some of the gods of the Plains Tribes being subsumed into the personality of a similar Båtjorder god, others becoming their own personalities in the Båtjorder pantheon. This religion slowly gained momentum, and in the 1200's, with the rise of the Svertings, it became the main religion in Solenjord.
Under various Sverting kings there were a series of religious reforms, which slowly regularised the religious practices in Solenjord, and cementing the religion as one of the things that united all Solenjorders, regardless of whether they were Båtjorder, Plains or Mountain Tribesman. These reforms aimed to vaguely emulate the Werklander system, and grouped areas into Musterjar, Temples. Each Musterja had a Godi, who in some of the larger Musterjar had several under-priests, and the Godi was under the control of the High Priest, an office which was obtained by being elected by a meeting of all the Godir, and then approved by the king. Even if every Godi had voted for somebody, without the king's approval you could not become High Priest (Though this sort of thing was rare). Similarly, an area's Godi was elected by a meeting of all the free men of that area, and approved by the High Priest. However, in the case of a mere Godi, if the High Priest denied an elected man, the case could be taken to the king, and his approval or disapproval was final.
In this way the religion of the Båtflygtninge who moved to Solenjord slowly became a very different animal from the religion of those who remained in the Archipelago, and it also drastically changed the local religions of the Native Tribes, as well as forming part of the basis of Solenjorder national identity. Nevertheless, it never quite lost its link to the Archipelago, and in the Konigtum
led wars that attempted to impose the Faith of the Three
in the Archipelago in the 10-1200s, the Solenjorders frequently came to the aid of their Båtflyktingar cousins, and surprisingly often were joined by Mountain and Plains Tribesmen who were willing to defend the gods who they had adopted into their own pantheon.
