Laverathian Basin

The Laverathian Basin is located within the northern region of the Eadrenan. As it is the site of the isolationistic Laverathian Empire, it does not appear on maps crafted in the surface world. However, it is regarded as its own geopolitical entity to those who know of it. An international treaty bars surfacer ships from legal entry to the Laverathian Basin.
