The Bloody Border refers to the region at the junction of the Southern Countries of the Human World and the southern Kawa Great Forest of the Seta Continent.
This area extends for hundreds of kilometers, and for thousands of years, the beastmen within the Kawa Great Forest have been engaged in seesaw battles with human soldiers from the Southern Countries in this area. The blood shed by humans and beastmen has nearly stained every piece of land red, hence it is called the Bloody Border.
To resist the invasion of beastmen from the Kawa Great Forest, several duchies in the Human World's south, bordering the Bloody Border, formed an alliance, relying on cities to establish a massive defensive line within the border area. They connected these cities with walls using a large number of enslaved farmers, ultimately forming the unbreakable Bloody Great Wall.
