In a fairy community, all trees are magical and sacred to them, however not all are sentient. In fact only a few are found to be.
These are Treefolk. Treefolk, as they are called, can take on humanoid shape and move a short distance from their tree, or, in extreme cases, uproot the entire tree and use the roots as a shuffling form of locomotion.
In their humanoid form, Treefolk are often described as resembling their tree, so that an apple treewoman might have green hair and brownish skin while an elder treeman might have eyes as purply black as berries. They can have trunk like legs, great branches for arms and have wood for skin.
Treefolk hate anyone who cuts down trees.
They will die if they are cut down, although some linger on as spirits to haunt those that caused their demise. They also have a fear of fire as it can do them great harm.
