Once every generation the Earthmother chooses a new born baby to be her mortal champion. Such a chosen is always female. Most of the time the chosen doesn't even realize that she bears some of the Earthmothers' essence. Only in times of great need the Goddess reveals herself in some sort of manifestation and informs her chosen and the druids in a dream vision for her daughters protection.
