The sun is the celestial body which gives Nirn its natural light. It is unknown whether the sun is a star around which Nirn spins or, as some believe, a large hole in the fabric of Aetherius which feeds the world magicka.
Culture[]
Many relate the sun to Magnus, the esoteric god of magic. Believing that during the Dawn Age he escaped from Nirn by tearing a hole through Aetherius. They thus believe that the magic present in Aetheius flows through the hole into Nirn.
