Dryads are
Greek mythological creatures that live near trees. They are a particular species of
nymph. Dryads are born bonded to a specific tree. If they lived in the tree, they were referred to as
hamadryads; otherwise they were simply dryads. If the tree died, the dryad associated with it died as well. For that reason, dryads and the gods punished any mortals who harmed trees.
