Daga is a specter, a wan and frightening thing without substance to strike or force to scatter. He is imprisoned within a carefully sealed jar kept at Orlanth‘s bedside. When people sin and forget the gods, the jar is opened or broken and Daga swims out to blight the earth and bring people back to a remembrance of their gods.
He is pictured as a skeleton, a death-specter, or as a dying child ravished by malnutrition.
