Druid Circle: Circle of Lesser Spirits

The Circle of Lesser Spirits is comprised of druids chosen as intercessors by some lesser deity. For whatever reason, this little god has incarnated as a beast and begun teaching you the secrets of the natural world, presumably to pursue some inscrutable purpose or achieve some goal necessary to its preservation. It begins to travel with you and aid you in combat. In exchange you honor it by assuming no form other than its own. Eventually you can have it assume a divine mien that can stand toe to toe with elemental, fiendish, and undead threats.
