Ghân-buri-Ghân, or simply Ghân, is a character in the epic fantasy The Lord of the Rings by J.R.R. Tolkien. Ghân is the chief of the Drúedain, also known as the Woses, the wild men who inhabit Drúadan Forest. In the third volume of The Lord of the Rings, The Return of the King, he leads Théoden, King of Rohan, through the forest so he can reach Minas Tirith with reinforcements. In return, Théoden promises that his people will have peace with the Drúedain, and that his people will wage war and drive away the gorgûn ( Orcs), that Ghân hates so much and that have been troubling the Drúedain. In the end of The Return of the King Aragorn, the newly crowned King of Gondor, gives the Forest of Drúadan to Ghân and his people, decreeing that none shall enter again without his leave.
Ghân-buri-Ghân is perceived as a "leftover," a prehistoric type of human surviving in the modern world. Like the rest of his people, Ghân has a flat face, dark skin and eyes, and wears only a grass skirt. He is seen as a "good guy" with a kind of primitive nobility, a classic example of the noble savage. He is by no means stupid, and he "refuses to be patronized."
