Kerrigan, b**** queen

Knight of darkness, Queen of Blades
Evil soul, the devil's shade
Ripping, tearing her enemies apart
Rage fills her darkened heart
In her eyes there lies no pity
Gone are her feelings and humanity
Anger fills her tormented soul
Now, destruction is her only goal

Buried in her dark, infested soul
Is there salvation or a heart of coal?
Too great has become her pain
Cold and ruthless, she'll fight until she's slain
Hatred is driving her insane

Quenching her thirst for power
Until the Universe belongs to her
Ethereal, she shines like a dark light
Eternal is her incredible might
No more will she ever stop to fight

Author's note: Here's to "My name is not important": I know I'm always
criticizing you for the length of your rhyming lines, but I just wrote it
in a way that would make it cool. Also, there's a hidden message somewhere.
Can you find it?
