The "Two Trees of Valinor" are two legendary trees named Telperion and Laurelin from J.R.R. Tolkien's mythology. They were created by the Valar to illuminate the land of Valinor, providing light before the creation of the sun and moon. Telperion produced silver light, while Laurelin emitted golden light, together creating a beautiful and harmonious environment. These trees were central to the history of Middle-earth and were cherished by the Elves. However, they were ultimately destroyed by the dark being Melkor and the giant spider Ungoliant. Their demise led to the creation of the sun and moon, marking a significant shift in the world's illumination.
