Deepmire, or just The Mire to most, is an unforgiving swampland filled with man-eating reptilian creatures. Tales and songs about Deepmire usually involve Val Madrigal, the Knight of Wintergrave.
Legend tells of Madrigal and the dragon Xaghastixia. Xaghastixia killed the Knight of Wintergrave’s wife and young child and Madrigal swore an oath to hunt down and kill the dragon. Most of the stories tell of his heroic defeat of the dragon, most also skip the part where he lived sad and alone in his castle until his 74th birthday when he climbed from his death bed and wandered into the forest in a fever to die.
