Mithril is a fictional metal found in the works of J.R.R. Tolkien, particularly in The Lord of the Rings and The Silmarillion. It is known for being lightweight, incredibly strong, and resistant to corrosion. Often described as silver-like in appearance, mithril is highly valued and sought after for crafting armor and weapons. In Tolkien's legendarium, mithril is primarily mined in the Moria region by the Dwarves. The metal's rarity and exceptional properties make it a symbol of wealth and craftsmanship. Items made from mithril, such as Frodo Baggins's shirt, are considered precious and often have significant historical importance.
