The border of the Dark lifeforms was actually a rather large region. This place was adjacent to the Law Realm, and in order to avoid conflicts, both the Law Realm and the Dark lifeforms tried to avoid having their people live in the region.
Of course, there were exceptions to everything. A few frontier folk chose to live in this dangerous region, and even trades between the Law Realm and the Dark lifeforms happened in it. Still, outsiders would never be able to truly get close to these secret exchanges.
The most numerous inhabitants of the border region were not sapient lifeforms but rather the various massive Dark lifeforms. This was because the strongest beast tamer of the Dark lifeforms, Moha, lived here, and his innumerable Dark Behemoths were the strongest barrier between the Law Realm and the Dark lifeforms.
