Guerilla Union of Shrews in Mossflower

The Guosim is an important group of shrews that traverse Mossflower Woods and the surrounding country. They are water creatures are typically use logboats on the many streams and tributaries for transportation. An argumentive and indecesive bunch, they are nevertheless deadly in battle and never unwilling to help Redwalls or other good creatures, and often act as transportation, crew or bodyguards for the protagonist.

They are always led by a Log-a-Log, a tough male shrew who commands the bunch and is usually a bit more laid-back and less argumentive than the average shrew. The weapons of choice for the Guosim are small, deadly rapiers, and they often wear brightly-colored headbands. They love to eat.

The Guosssim is a southern faction of the Guosim and is characterized by the usage of the Blackstone, which defines rank.

It should also be noted that in Redwall there are inconsistancies involving the Guosim; for instance, instead of the band having the name, an individual shrew was named Guosim. The error was rectified in all other books.
