They are always led by a Log-a-Log, a tough shrew who commands the bunch and is usually a bit more laid-back and less argumentative than the average shrew. The weapons of choice for the Guosim are small, deadly rapiers, they also use bows, and slings. They often wear brightly-colored headbands. They love to eat, and Guosim cooks are considered to be some of the best in Mossflower. Guosim are also often called rivermice by vermin. Guosim law states that if a Log-a-Log is murdered, his death must be avenged, and the shrew that avenges his death becomes the next Log-a-Log.
