The Fall of Odin

Vulgar Loki, dark shape shifter
  Betrayer of the Gods
  Enemy of all of us
  From him, the wolf was born

Invincible Fenrir, mighty and strong
  You were lured and trapped
  With chains made by dwarven hands
  Sealed deep in stone

Darkness comes at the end of time
  The devastation that will befall us
  Will Gods and men alike slay
  Then you will break free

And from the ground, you will rise
  Mouth gaping, teeth sharp
  Into the neck of Odin
  His blood will flow and dry

Ragnarök, the end of ends
  And yet the new beginning
  The world will burn, then flood wet and cold
  And from the ashes will rise anew
