Edge Of Sanity - Achilles Heel

This tome presented many further views
Essential rules of power were revealed
And thus the pages offered up one clue
The child bore one significant Achilles Heel
Should the Crimson Queen be blinded,
then powerless she'll be
Bereft of piercing vision,
her victims will be free

Salvation lies in
banishing this creature to the dark Let not your hand be hesitant
or death will be your mark
Lest regained sight
should speed her flight away from burning hell
A steady heart must seal her back
within her crimson cell

And thou who didst release
this most vindictive enemy
Must serve to be her
warden there for all eternity
