Earthborn

Earthborn are a mysterious race of large humanoid rock creatures which are genderless. Where they come from, and whether they are created or born, is a mystery. They seemingly come from nowhere, even the Earthborn are unaware of their origin as they are incapable of forming any memories for the first few years of their life. They are hardy, and have an innate sense of guardianship over other good living beings. They have no real purpose in life, but feel the constant desire to leave the world better than when they arrived in it. They have no true desires of their own, and have no ambition. They aren't greedy, though see the value of wealth in regards to how they can better aid others however Earthborn are known to rather enjoy the luxurious snack of gemstones, they say each stone tastes different and the greater the value the finer the taste. It is believed Earthborn were created by the good gods purely to help protect the realms, though it is uncertain.
