The Fine Line

The borderlands that separate Doren and Alberea from Montclaire.

The Fine Line was once a beautiful and blossoming natural region of largely untouched fields, except for the Dorenese and Montclairoise farmers that settled there harmoniously. It served as a large stretch of land that stood for the century-long peace between the regions of Toussaint, as well as a physical buffer between the culturally vastly different civilisations of elves and men.

In 1379, a terrible plague that would later come to be known as the Cobalt Plague broke out on the Fine Line, near the Dorenese Melchior Becker's farm. The plague would spread through the vegetation of the region and would ravage the borderlands in the years to come. The Cobalt Plague and destruction of the Fine Line, including the heightened racial tensions that followed, ultimately led to the breaking of the century-long peace and the start of the Great War in 1380.

Revelations
During Episode 1, 2 and 3, it was revealed that Eliott Castan, a Montclairoise elf now living with the Lavornes, was partly responsible for the start of the plague. Instructed by his mentor Regis Provost, an elven insurrectionist previously working for the Delphine Division, and provided with a mysterious cobalt blue liquid, Eli poisoned the great oak tree on Becker's farm.
