"I am your worst nightmare. I have conquered fear, I have come to terms with terror and pain is my best friend. I will come from nowhere, i will dissapear without a trace. My brothers and sisters will lay down their lives for me, as i will for them. I am a UNSC SPARTAN. The first and last line of defence."
