Blackmarsh

The broad swampland that acts as a natural boundary in Valden, the Blackmarsh is essentially a mix between swampland and the delta to the Cosoon River, which all intermingle with the southern Avalia Ocean. The problem is that the marshland is incredibly unstable, with widely varying degrees of depth, resulting in quicksand, warrens for underground and underwater creatures, and inhospitable terrain. Despite this, there are several thriving elven settlements, and the elves themselves seem to understand the marsh very well.
