>>122048155Might be the equivalent of Iceland, or a rural area of Norway. Trolberg isnt a large city and is fairly rural with it being infested with trolls outside the city. It does have a railway station so it is connected to at least another major city.
Trollberg is probably like the equivalent of an Alaskan city. Fairly isolated possibly being the only source of human civilization for hundreds of miles before you reach an outlaying settlement where things are much safer. That said Trolberg still seems to get new influx of settlers like twintails, and has some industries worth exporting. Given Hilda involvement with Jorts, it transformed into a local product into a multinational empire. So it probably now become something like Coca-Cola, where you associate a city with a well known product.
