1) So the idea of Nilsova being primitive mostly comes from the fact that society in the swamps is much less structured and hierarchical than the other regions, the coexistent, cooperative relationship with nature they tend to have, and the generally isolationist attitude most in Nilsova have toward the world outside the swamps. Now, in actuality, there’s a bit of truth to them being less advanced, in that Nilsova has basically no Magi tech, at least not that they made themselves. There are artificers in Nilsova, but they tend to modify and reverse engineer foreign technology rather than making their own.(you’d be surprised how easy it is to misplace an airship) As far as their actual civilization though, Nilsova has a few larger settlements, though cities might not be the right word. By design, a lot of the region remains wild, but natives are pretty adept at navigating the riverways and swamps. Most people live in smaller settlements. Some don’t live in any fixed location, instead opting to live nomadic lives on riverboats. Basically, there’s a variety of lifestyles in Nilsova that outsiders don’t know about, and while they may seem somewhat primitive, it’s more that they’re just very different compared to their neighbors.

2)That could absolutely work. Hunting parties would totally still exist in Nilsova, as it has probably the most, uh, concerning wildlife out of the regions (excepting maybe the far north of Verholt and the Sphinxes in Isila). It’s not known to outsiders, but Otherfolk still live deep in the swamps as well, and children of mixed lineage are not, strictly speaking, uncommon, though first generations are a bit more rare. For instance, Linxi has faeblood, though it’s a few generations old. Usually these children have unique magical talents, as many Otherfolk have innate magical ability. Your premise sounds like it fits in just fine! 

And no worries, ask as many questions as you need, it’s what I’m here for!
