Fatch was a young Guosim shrew. While aboard the Pearl Queen he very nearly fell overboard until he was rescued by Rufe Brush. He swore to protect Rufe - this came to fruition during the Battle of Southsward, where Fatch sacrificed his life to save Rufe from Silvamord. Rufe later named one of the Swords of Finnbarr Galedeep Fatch in the brave shrew's honor.
