Back when Lucas had headed into the Millennium Mountains in search of the Aión source —the Heart of Silver— there was a crisis that threatened the Neon Summer province of Trundel City.
A desolate beast wave with at least one hundred thousand desolate beasts ranging from the third to fifth levels, and rated as a Class B threat was approaching the city.
A Class B threat was a threat that could wipe out one or two districts in a city-state. In the Belfargos region, major cities were the equivalent of a district, so a Class B threat could take on one or two cities. In other words, the desolate beasts wave had the ability to wipe out Trundel City.
Due to this, the Desolate Beasts Conflict Organisation, or DBCO for short, was called in to handle the crisis. The DBCO was an organisation founded by the authorities in Belfargos City to handle the threat of desolate beasts in the region, especially from the Class A desolate beasts domain, the Millennium Mountains.
