Tree-Demons

Tree-demons are a race of demons that typically live in woodland areas. Their flesh is made of a hard, wooden matter that blends in with woodland areas.

Physiology
Tree-demons purposely resemble the appearance of tree trunks. This is used as a predation method so that they can ambush their prey.

Like all other species of demons, tree-demons are nocturnal creatures. It is not known exactly why this is, but it is suspected to be another way to ambush prey as it is easier to capture when it is asleep.
