The Fen Guardian is a massive, walking heap of decaying vegetation, roots, and mud, animated by a primal swamp spirit. Its form is constantly shifting, allowing it to ensnare and absorb unfortunate trespassers into its verdant mass. With surprising agility for its size, it patrols the ancient bogs, its tendrils crackling with absorbed atmospheric energy, ready to lash out at anything that threatens its watery domain.
