TWO PRIMARY LOCAL CULTURES
The Yuorics and the Danneins collectively have been in an interaction of cultures between one another over the last 150 - 250 years (depending on exact location within the Marke Lands). The Yuorics originate from the westernmost continent of Nadril and arrived on the Andra Peninsula by boat. They sailed from across the expansive Moctura Sea, island hopping through the straits of the Gaeirmund archipelago. The Nadrilian westerners have gradually established a foothold of Yuoric culture in what was to them a foreign land of the east. They came initially for the lure of exploration and trade. They quickly decided to establish permanent settlements to mine iron and copper, log dense timberlands, and farm the rich Andran soil.
The interchange between the Yuorics and Danneins started as a "clash of civilizations" but has ever so gradually trended towards a "blend of cultures", with the more dominant Yuoric culture enjoying the heavier part of the blend largely because of its higher developed culture and technology. That being said, there are still lapses back towards the clash scenario. Several factions on each side even strive for more confrontation, though many others call for peace and cooperation.
Along with obvious technological and economic disparity between the Yourics and Danneins, religious differences could be argued as one of the most volatile points of contention between them. The Yuoric people generally have only one religion (though not all are true followers of it by any means) in the veneration of Gellir, whom they think of as a deity over the entire earth and a sponsor of mankind as a whole. In practicality, Gellir is thought to favor the Yuoric people and their highly developed culture. The Church of Gellir is highly integrated into Yuoric culture and government.
The Danneins recognize a wider and more diverse pantheon of nature-oriented deities. Some of the deities are benign, a few are aloof and indifferent, and others are quite vicious. The Danneins call this deity set the First Gods. Non-Danneins most often call them the Land Gods, the Dannein Gods, or even the Savage Gods. The largest point of contestation is that one or more of the Dannein gods call for, or at least allow for, human sacrifice, a practice that is completely intolerable to the Church of Gellir and a sign of true savagery in the eyes of the Yuoric people.
Perhaps strangely, perhaps not, the Danneins have extremely similar physical characteristics as their encroaching Yuoric neighbors. A few bold sages of the Yuoric cities suggest that the two people were related in a more distant past, sharing ancestors who separated one from another in an early, pre-historic time. Most reject this theory, though the physical similarities remain undeniable, at least in general trends.
