Mythril (item)

Mythril (ミスリル Misuriru) is a valuable metal found in the Final Fantasy series. It can be crafted into many pieces of equipment, like swords, armor and gauntlets. The name seems to be derived from a metal called Mithril, appearing in J.R.R. Tolkien's fictional universe, featured in "The Hobbit" and "The Lord of the Rings". In fact, in Final Fantasy VI, it is called Mithril. It is a possibility that it is intended to be "Mithril" in English, but was changed to "Mythril" iafter Final Fantasy VI to lessen the chances of a copyright lawsuit from Christopher Tolkien, who is infamously very litigious.
