Each mischief of mice (for that is what a group of mice are called!) is led by a queen. \n'b' The average field mouse is fearful of most everything, and for good reason. They are considerably more powerful in groups however, and even more so when led by a queen. \n'b' Field mice are led in massive groups numbering in the thousands by a queen. Field mice queens are knowledgeable about much of Faerie and can be invaluable advisors, particularly out in the wildlands where civilized consultation is in short supply. They also make excellent guides and can act as the guiding force behind field mice swarms. \n'b' Then gathered by a queen or called by a whistle of field mice summoning, the little field mice become a potent force capable of dragging any heavy creature or object. \n'b' These swarms number up to eight, or about a thousand mice per swarm.'
