The First Age is a significant period in the mythology of J.R.R. Tolkien, particularly in his works The Silmarillion and The Hobbit. It is characterized by the epic struggles between the Elves, Men, and the dark lord Morgoth, who sought to dominate the world. This age is marked by the creation of the Silmarils, three precious jewels that held the light of the Two Trees of Valinor. During the First Age, many legendary heroes emerged, including Beren and Lúthien, whose love story is central to the lore. The age concludes with the War of Wrath, leading to the downfall of Morgoth and significant changes in the world of Middle-earth, setting the stage for the subsequent ages.
