Isis "ghost key"

it's cold snowing blue light dusk settles
a fire burns with failing light against the growing darkness
bending over the dying flames you were with me then as always
through the fluttering veil of frozen blue a hooded figure cuts its path
to cleave the night in two
pull its outer husk from its body and the rest escapes
and there upon the ground the remnants of our struggle
this is the ghost key
