The Earth Kingdom is high up in the trees of the forest. This kingdom has a group of elders that rules the forests and they are the ones that live in the castle. The others live in the treetops in tree houses of sorts. The houses are all connected by rope bridges so travel up so high is easy. Even though the earth elementalists live in the trees, they spend a lot of their time on the ground. Physical abilities are very important to the earth elementalists and they often hold Olympic-type races and contests to prove who is the strongest.

In the Earth Kingdom, women are just as strong as males. There is no discrimination, unlike the Fire Kingdom, and there is an even amount of female and male elders. The earth elementalists are also brilliant at both long-range and hand-to-hand combat. They don't have steel weapons like the Fire Kingdom, but wield hand-made bows and arrows instead.
