Beoluska

Orth refers to some isolated islands and towns that encompass the Abyss, while Beoluska (ベオルスカ) is a more macro distinction that includes the entirety of that, plus other islands and territories.

Beoluska is the country encompassing those islands as an archipelago. As a country, Beoluska is a large and powerful nation-state. It encompasses not just those islands, but also parts of the nearest continent, in its territory. However, some events led to the area being split up into East Beoluska and West Beoluska.

Orth imports products such as rice and other exotic foods from both East and West Beoluska.

Orth is located in the southern seas of Beoluska and is protected by the nation, so that people from other countries can't abuse it. One of those policies is requiring Delvers to earn their Whistles through a licensing system.
