Prince Durin IV (Owain Arthur) has been hiding something since his debut in The Rings of Power, and Episode 4, "The Great Wave," has revealed the truth. Mithril is a mineral that has a long history in Middle-earth.
Elrond (Robert Aramayo) learns that Durin is going to a remote mining tunnel. Durin answers the question, calling the substance "gray glitter." When Elrond asks what it is, Durin approximates it to be "mith-raud." The two words are pronounced differently to Tolkien fans.
Elrond and Durin exchange a small piece of mithril for a token of friendship. The mine caves in, trapping four Dwarves, and Durin's father decides to shut down the mining operation, much to Durin's chastisement.
Mithril Throughout Middle-earth
Mithril is a precious metal that is both lightweight and strong. It's worth ten times that much in gold and does not tarnish. It's valued by all of Middle-earth's people. Khazad-dum, more commonly known as Numenor, is one of the few locations, along with the Dwarves.
The metal was sometimes referred to as the Elven name, although it was most commonly known as the metal. Men used the terms Moria-silver or true-silver, and the Dwarves are said to have a secret name for it.
Mithril helmets wore by the guards of Minas Tirith lasted for generations as a remnant of their former glory. A second Elven ring was given to Galadriel and will likely appear later in the series.
The words "speak, friend, and enter" are used in the Doors of Durin, as well as by Celebrimbor (Charles Edwards) and Narvi, the dwarf who guards Moria against foes. In The Fellowship of the Ring, Frodo and his companions encounter these doors on their journey. When Merry Brandybuck asks Gandalf the word "Mellon," the doors swing open and allow the group to enter.
The mithril mined from Moria was given to Bilbo as a reward for his heroics against the dragon Smaug, and the same mithril armor saved Frodo's life when it deflected a dangerous blow from the cave troll.
The Fate of Moria
Moria was the only remaining place where mithril could be found in the Third Age. The Dwarves became greedy, and they dug deeper, but they went too far, killing a powerful fire demon. This Balrog became known as Durin's Bane after it killed the Dwarven king and sent the rest of Khazad-dum's people fleeing.
Moria became the home of Orcs, but they avoided the depths where the Balrog remained. Eventually, the Dwarves attempted to reclaim their ancestral land, but they lost all of their lives and, in the end, were unable to return to Khazad-dum due to the Balrog.
Balin decided to resettle Khazad-dum some years after his adventure with Bilbo Baggins. They remained successful in reclaiming the Eastern halls after five years. They died as Orcs because to the fact that they had lost contact with Balin.
Gimli suggested a route through the mines when the Fellowship arrived, believing Balin to be in charge of Moria. They went further and discovered that the Balrog had infiltrated the city of Moria. Gandalf tried to guide the Fellowship away, but the Balrog pursued them. Gandalf fell with the Balrog until they reached the highest point in Celebdil. There, the wizard and demon fought for two days and two nights before Gandalf defeated the Bal
A descendent of the House of Durin successfully restored Moria following the destruction of the ring and well into the Fourth Age. Dwarves were able to return to their long-abandoned home once more.
What Does That Mean For 'Rings of Power'?
The Numenor's destruction would be exciting, but these events are likely to take place hundreds of years later. While the Numenor's destruction would fit the Numenor plot perfectly, The Rings of Power would go into the future of Khazad-dum's.
