I also like the names, and I'm curious about Ourmthotter. At first I though it said Ourmother, which lent itself to all kinds of interesting ideas about the culture there.
I also immediately started thinking about the geopolitics of this map particularly how the very large (and very small) landlocked countries might develop differently and interact with their coastal neighbors. I'm very curious to see a basic breakdown of where mountains, rivers, forests, etc are, as that could obviously have further complications.
Good work on your first map.
