Murderous tyrants of marshes, swamps, bogs, and fens, black dragons terrorize their domains with intense fervor. Gleefully sadistic, they rule their fetid principalities from a deep cave or otherwise isolated part of the swamp with a mix of lightning-quick raids and subterfuge. Their hatred for other creatures is as acidic as their breath weapons, and they rarely tolerate even other dragons of their kind-except perhaps to mate or temporarily collaborate to take down a mutual enemy.
