The twisting Servant River neatly halves Antonica, and it keeps the plains in the middle of the continent fertile and green. Starting inauspiciously at the lake near Halas, it flows quickly over sharp rocks down to a branching in the middle of the continent. Its west branch is used for barge travel, and small riverside communities dot the banks of the water. The east branch becomes the Lifire River, the chief source of water in the Desert of Ro. The water wanders muddily in the southern part of Antonica before it empties into the Gulf of Gunthak.
