Furmo was the Log-a-Log of the Guosim at the time when Martin the Warrior went questing for his father. Furmo was only too eager to help Martin on his quest, as the Guosim shrews were growing restless and quarrelsome.
Furmo and his shrews accompanied Martin and his friends as they traveled to the North Shores. In particular, Furmo took charge of the ship they captured from Sholabar's band, renaming it the Honeysuckle after his wife. He navigated it skillfully through the perilous Tall Rocks, and when they returned to Mossflower Woods he supervised the fitting of wheels to the flat-bottomed craft, turning it into a land-sailer. He presented it as a gift to his wife.
Furmo was a fine fighter and a good leader of shrews, as well as an excellent cook. However, of the few things that intimidated him his own wife ranked first on the list. Furmo himself admitted that Honeysuckle was the true leader of the Guosim.
Not to be confused with Furm.
