The Drowline is a Two mile wide swath of land that stretches from the Northern edge of the Serranzia all the way to the Southern edge. It is used to demarcate the boundary between the West Forest and the Mid Forest.
The land is inexplicably dark and swamp like. Many foul and evil creatures call this area their home. Many do not dare to cross it, even those who face the many dangers of the Elfwood as a profession.
It is thought to be a byproduct of some spell cast during the Old War. Though with many not convinced that the Old War even truly happened, this is often written off as a conspiracy theory.
