Muris are the most prolific species of faunus, and are by far the most well-integrated into modern society. Standing half the height of an average human, muris are mouse-like humanoids, with somewhat disproportionately large hands and feet. Muris live in large familial units, known as nests, typically on the lower-end of the middle class neighborhoods in kingdoms. Those that live in the countryside tend to form villages with other nests, but commonly travel to more integrated villages for trade and friendship. Muris are generally a friendly folk, always ready to help a friend or stranger in need - they have earned a strong reputation as hard workers and good companions.
