Nearly all older trees growing in the wild have an elemental spirit dwelling in them called a Dryad. They are the energy within the tree that has taken form. Dryads appear young, and only grow old near the end of a tree's life. However, almost no trees die of old age, but instead die of fire, rot, earthquakes, lumbering, etc. They can use green magic and have control over plants, but must lose power if they go to far away from their tree. They appear similar to elves, but their skin is made of wood or vines.
