Subjectively, in your own headcanon.

Also, we went from
'Wolves don't eat stone walls, they want to eat people'
briefly to
'Wolves love to eat stone walls and prefer them over eating people and will destroy all the ancient structures of the world for lulz'
back to
'Wolves ignore stone walls unless MAYBE the player is on the other side'

Also, bear in mind the notion of a universe where any/all reasonable expectations are unbound by "because magic" wherever a convenient explanation of anomaly is needed, loses all coherency and literary value.

I'm pretty read on Norse myth, and this is the developers own inspired creation, not a exact mythological simulacrum. No mythos is abstract. Regard must be taken to maintain a fundamental coherency to the expectations of perceived human experience or it loses value to humans.
