Radeln is a vast savanna covered with long grass and peppered with occasional spindly trees or small shrubs. It receives heavy rainfall during the colder months of the year, and is exceedingly dry during the spring and summer. The area is prone to widespread fires during the dry season, though the grasses and shrubs grow back quickly during the rainy season and the trees are rarely affected by the fires due to their heat-resistant properties. Animals commonly found in parts of Radeln include giraffes, zebras, buffaloes, kangaroos, mice, snakes, termites, beetles, lions, and elephants.
Radeln is populated by tribes calling themselves The Tribes of the Vogel. These tribes consist of either humans or gnolls. The humans live in semi-permanent settlements where they practice primitive agriculture. Human settlements rarely exceed 100 members (the exception being Stark). The gnolls live by hunting, and follow herds of animals across the Radeln.
