Redwings, Blue Fangs, and Black Tideings.
The Blood Marsh is called such because much of the vegetation has a dark red color. Because of this occasionally the water there will resemble pools of blood due to the submerged vegetation.
The marsh is home to many dark and hostile creatures and is considered to be one of the more dangerous areas in the Northlands. Despite the hostile conditions some groups of people have made their home there. Generally a much heartier and tough group the people living there have established several villages nearer the outer edges of the marsh.
