Part 3/7:
As a Maia, Arien was entrusted with the monumental task of guiding the sun, a duty that underscores her significance in the cosmology of Middle-earth. The Valar chose her for this honor due to her unwavering determination and her inherent connection to the light of Laurelin, one of the Two Trees of Valinor that once illuminated the world. This association with light symbolizes hope and purity in contrast to Melkor's dark endeavors.
When Melkor destroyed the Two Trees, he caused cataclysmic changes in the world, ultimately leading to the creation of the Sun and the Moon from their final fruits. Arien’s transformation into a blazing embodiment of light represents her acceptance of this celestial responsibility, which placed her on a celestial stage, illuminating the skies and the lands below.
