When a Seraph goes bad

Heavenly outcast with ebony wings,
they say Satan himself thy praises sings.
Escorted out of the Eternal Kingdom above,
all because you enjoyed a different version of love.
You have been many things down through the ages,
played many a role on man's historic stages.
With a lovely continence that's a deceptive facade,
(rumor has it you were once the mistress of the Marquis De Sade).
You tried to be normal and once met a handsome young gent,
his short time with you was unfortunately spent.
You wooed him one night into your downy-soft bed,
ate out his heart and at the gates of hell placed his head.
That coupling left you with an eon long curse,
like the thirty pieces of silver in Judas' purse.
Unnaturally conceived on this orb that spins and twirls,
you became the mother to twin little girls.
But, one is a cyclops and the other covered in black hair,
together they make a most hideous pair.
They have an ravenous appetite for human blood,
and the nest they live in is a crimson flood.
Every night you must go out and test your skill,
with the intent of making a murderous kill.
As your prey struggles for life and piteously bleed,
you wince as your daughter's sate their unquenchable need.
So, now you know what happens when a Seraph goes bad,
they live out a life they wish they never had.
And on these Autumn nights when you are out on a lark,
the air turns cool and it grows eerily dark.
Look around, for hiding behind a gnarly oak tree,
a heavenly outcast may be out hunting for thee!
