The marsh-dwellers are the people who live in the swamps near The City. They are known for their use of a particular kind of moss that grows in those marshes, which they use to make boots that make them silent killers. The moss can also be used in special Moss Quivers to make arrows silent.
- This and their use of moss may be a reference to the Pagans of an earlier time in the history of Thief. Yeperdoodle
