The creature

The Swift shadow,
of all the evils the darkest,
from it's freedom comes it's strength,
from it's speed its power,
gathering new force as it goes,
beginning small,
fragile,
a timorous creature,
but slowly it grows,
as it's power increases,
grows to tower into the sky,
fleet of foot,
swift of wing,
it is a vast,
fearful monster,
at night it gives flight,
preying on those below,
hissing in the dark,
whispering to all,
never giving in to sleep,
forever whispering,
as the sun sneaks over the horizon,
it takes its leave,
returning to the shadows,
hiding from the light,
perches on a rooftop,
striking dread in all around,
dread of when the sun seeps away,
of when the moon returns,
and its flight begins.
