I've been following the discussion about how Yelm crosses the sky each day,
and a question came to my mind that can be related to this issue:
Nights are dark, but is this elemental darkness? (I supose so, since when
Yelm died the darkness was expeled from the underworld to the surface
world.)
If the dark at night is elemental darkness, where does it came from? And
where does it go in daylight?
