Requires some knowledge in Germanic/Norse mythology:

A hall she saw standing
remote from the sun
in Náströnd.
Its doors facing north.
There fell drops of venom
in through the roof vent.
That hall is woven
of serpents’ spines.

She saw there wading
onerous streams
men perjured
and wolfish murderers
and the one who seduces
another’s close-trusted wife.
There Nidhögg sucked
corpses of the dead,
the wolf tore men.

• Edda, Völuspá 36,37
