Obsidian Peaks (Volcanic)

Of course, it helps that Dextroluma who are genetically adapted to the region are not harmed by lava and magma.  It is believed to be an innate form of magical protection.  Still, other parts of eruptions can harm them - not to mention other residents without that innate defense - so there are many efforts made by the nation's Volcano Management Department to avoid pressure buildups in magma chambers that could lead to eruptions.

Perhaps due to this extreme environment, the Obsidian Peaks tends to adapt new technologies rapidly.  The residents and leaders are deeply interested in anything that could keep their dwellings, possessions, and information secure even in the face of major eruptions.  As a result, of the surface nations of Aerius, it tends to be the most technologically advanced and the fastest to adapt something new from Galactica, the Arcane Artifice, or other worlds.  However, if a technology turns out to not be very useful, it will also wind up ditched very quickly - citizens of the Peaks have little patience for duds.

The Peaks tend to rely more on other nations for food, exporting more in the way of ordinarily rare resources that come from their volcanos.  The edges of the nation have very rich soil, though, so so what agriculture is done here is typically done near the borders.
