In southernmost Stygia, the great deserts break into patches of stinking marshland. Tropical trees there poke from the unfarmable earth. If one journeys further south, the marshlands turn thicker and the trees grow denser, until a traveler stands on the edge of the impenetrable jungles of the Black Kingdoms. There the Purple Lotus Swamp spreads like a bruise across the realm. Large marsh snakes glide underneath the silt-darkened water, ready to drag wanderers down into a drowning doom. Deep tar pits dot the landscape, filled with the bones of the unwary. For all that, though, the swamp is a well-traveled place. The attraction is the beautiful, valuable flower that grows here and nowhere else in Hyboria.
