Hildórien is a fictional region in J.R.R. Tolkien's Middle-earth, specifically located in the land of Beleriand. It is known as the "Land of the Dawn" and is situated in the eastern part of the continent. Hildórien is significant as it is believed to be the first place where the Edain, the ancestors of the Dúnedain, settled after leaving Middle-earth. The region is characterized by its lush landscapes and is often associated with the early history of the Houses of Men. Hildórien plays a crucial role in the lore of Tolkien's works, representing the beginning of human civilization in his expansive mythology.
