Often forests will be the home of Dragons, Dwarves, Elves, Fairies, Giants, Gnomes, Satyrs, Goblins, Orcs, Trolls, Dark Elves, Unicorns, and other mythical creatures. The mythical creatures may be sometimes be portrayed in some stories, as either living in a hidden kingdom or solitary. There may be trees that talk or with branches that will push people off their horses, thorny bushes which will open to let people in but close and leave people stuck inside, and other plants that move or turn into animals at night, or the like.
