The Completion of My Arm

As long as I have a pencil in my hand,
I hold the power.
I'm able to create what no one else can understand.
I can take life's greatest tragedies
And rewrite the ending to make it fit.
I can take a perfect romance
And destroy the desire they feel with a single betrayal.
I can create worlds
And lands that are too good to be true.
Dystopias and utopias come alive
In the palm of my hand,
Spilled onto a single page.
Magic can enchant,
Creatures can roam,
Lives can end and begin
All in the single sentence that I form.
One simple change can ruin everything that I have built up:
The butterfly effect.
I have complete and total control over my characters' lives,
Like a lord wreaking havoc or bringing joy to my people.
I'm able to play God
With the pages of my books,
And I know that I'd rather be in the story
Than in my actual life,
Because if I wanted to change the outcome,
I'd know how to do it.
Like Sweeny Todd and his razor,
My arm's complete with my pencil.
I am a dictator over several unwritten lives
And a soothesayer to those of whom will not survive.
I hold the power
To take their homes,
Food,
Children,
Parents,
Lives.
I hold the power
To give them gifts,
Curses,
Love,
Hate,
Reasons for life.
I'm the one they don't see,
But know is there.
I'm their past and their future.
I'm their beginning and their end.
I'm their fate.
As long as they are aware of that,
As long as they know,
In some strange way,
That I'm their creator,
As long as I hold this pen,
This pencil,
As long as I have this keyboard,
I have the power
To destroy and create.
I have the power
All to myself.
