Note: I included this poem in a Redwall fic (now deleted,) and it seemed to describe Garnet perfectly when I altered it a little bit.
*******
Little princess, little princess,
Not yet fit to be a queen
Little princess, little princess,
Is this what your fate's foreseen?
Growing monarch, growing monarch,
Do not cry for loved one's passing
Growing monarch, growing monarch,
Fight the evil fast amassing.
Desperate ruler, desperate ruler,
Still naïve in this world's pain
Desperate ruler, desperate ruler,
You must shine as shadows reign.
