Durin the Deathless is a legendary figure from J.R.R. Tolkien's Middle-earth, specifically known as one of the most important Dwarven kings. He is the eldest of the Seven Fathers of the Dwarves and is credited with founding the great Dwarven city of Khazad-dûm, also known as Moria. His reign is marked by prosperity and the discovery of rich mineral resources. Durin is unique among Dwarves for his long lifespan, living for several centuries. He is often depicted with a distinctive appearance, including a long beard and a crown. His legacy continues through his descendants, known as the Durin's Folk, who carry his name and honor his memory in their culture.
