Voluspa - Norse Mythology Book - Verse 45
“Brothers shall fight | and fell each other,
And sisters’ sons | shall kinship stain;
Hard is it on earth, | with mighty whoredom;
Axe-time, sword-time, | shields are sundered,
Wind-time, wolf-time, | ere the world falls;
Nor ever shall men | each other spare.”
Bellows Translation
