The Murkmire Marshlands were a large, swamp-like region in the Fencrest Foothills, where freshwater rivers met saltwater wetland. The marshland, located south of the hills of Cliffsunder, occupied a peninsula at the west edge of Commona, dividing the Bay of Broken Tides from the Splitmaw Strait. Bordered on three sides to open ocean winds, unique geologic conditions in its salty inner bogs created unique preservative properties.
The place was of great interest to both archeologists and those studying occult lore, as many remnants from the Pre-Unified Age turned up preserved in its swamps. Many books were written by Cliffsunder academics on the area, as such treasures as the Murkmire Stone indicated that it was home to more secrets than it seemed.
These efforts were often repelled by the small colonies of Elven rangers, Firbolg stewards, and Lizardfolk colonies in the mire, who sought to preserve its history and repel the Human invaders.
