The only reason why she can darken the world is because she is sealed away. With out her being active, the light from the sun is sealed away with her. Thus the moon would not work without the light of the sun.

science wise this is true. Honestly though there are most likely still other gods of the sun that can brighten things up not just her. So I would assume that just means that the world gets darker earlier.
