The Marshmen usually dwell in the swamps, only rising to the higher lands during Mistfall, which happens every fifty years or so. They are upright bipeds with light-brown leathery skin, five-fingered hands and fish-like facial features. Although possibly not fully sapient, these creatures are intelligent and extremely fast learners. Their bodies also have the ability (shared by other Alzarian species) to undergo rapid mutation in order to adapt to new environmental circumstances, such as developing the ability to breathe the poisonous gases released during Mistfall. Pure and concentrated oxygen, however, seems to be highly unpleasant for the Marshmen and hampers their adaptive abilities. It is thus a very efficient way to draw them out.
