Grullba Deathwind was a big male river rat, and the chieftain of a horde of about five score other rats. He was described as a real barbarian fighter, said to be able to take on any three of his band at once and emerge victorious. He was especially known for his skill with the battle-axe; his own axe had holes forged through the blade so the weapon, when swung, would create a whistling, swishing sound.
