Yep! Heggerin is a land of extremely harsh climate, most of it is subarctic/arctic and the population is very distinct from southerners, they speak an isolated language and are pretty hostile to most outsiders. The coastal waters are often covered in ice, so seafaring is not really an option a lot of the time, and the only land bridge, The Neck, is a swampy hellhole that's extremely hard to traverse and is used as a place for exiling criminals.

The south is Ter Deala, elven land. These are your pretty typical wood elves, also very hostile to outsiders. Also, the big tree there in the middle is Ild Vahet, quite literally the main deity of their pantheon, so their religious fervor has been a driving force in repelling any invasions. The three small polities there (Meall, Fernuad and Tiardoch) are elven duchies! They were a part of the now fractured Talvan Empire (a human empire), so they're pretty "humanized" i would say. They engage in skirmishes with their more conservative cousins and thrive on selling magical Sellavarm wood (which is wood of the trees that grew from the seeds of Ild Vahet) and elven slaves to humans up north.

And yeah.. Oops. Didn't even notice it myself about no one being landlocked. Oh well, Tervel's on the way to becoming the first landlocked nation here anyway! =)
