The world of Black Desert Online has been divided into two countries, the Republic of Calpheon and the Kingdom of Valencia, who compete for the Black Stone, an essential energy resource. These two countries are culturally and religiously different. Whereas Calpheon is more of a materialistic civilization, people in Valencia pursue spiritual values “Black Stones” litter the desert area separating the two countries, known to the people of Calpheon as the “Black Desert”. The people of Valencia call this area the “Red Desert” because of the blood that stains its sand.

Here, users must write their own individual story as part of the epic that is the Black Desert.
