Path of the Earth Bender

Your ancestors have a strong connection to the earth and nature around them and because of that came into contact with some giant moles that had the ability to instinctually mold the earth around them and formed a symbiotic relationship with them. after centuries of staying with these creatures your ancestors gained the ability to instinctually mold the earth around them as well, and this ability has been passed down through the generations ever since.
