Brackish trudges are lumbering masses of sentient fungus and vegetation that thrive in the bayou. They are living examples of the conflicting forces of life and decay existing in a harmonious cycle. Flowers and other plant life grow on their backs, necks, and heads. When these plants die, they decay and become the ideal habitat for fungi. The older a trudge is, the wilder and more varied are the plants and fungi that thrive in the tiny ecosystem on its back.
