All Hail The King Poem by Jacob Courtney

This is my kingdom. I rule with an iron
fist for I am lord, I am the highest
power in this land. You will do as I
say and beg at my feet. Forgiveness is
not in my nature for I am the fist of
vengence that destroys my enemies
before they can destroy me. Any who
do not stand with me are against me
there is no middle ground. I am
absolute in this. There is no swaying
me in any direction but my own. Not
even my wives can escape my wrath for
I decide who will live and who will die.

So can you tell me, what is my name?
