The Carnage of War

I sat in a large dark room, my heart beating between my ears at a pace that even I couldn't keep track of. From in front of me, a large screen lit up. I looked at the blank white page in front of me until suddenly a voice rang out from it. So loud that for a moment my ears rang. As I came back to my senses, I noticed words had appeared on the screen and a voice was reading a title.
"Please choose your class." A robotic female voice said to me. Seconds passed of me standing in shock.
"Please choose your class." The voice said once more, just as patient as before. I read over the three choices: 'Cheerer, Builder, and Warrior'
"Please choose your class." The voices reminded me once more. I squinted my eyes at the bright screen as I read the short descriptions underneath each choice. I held up a shaky hand my heart beating faster than ever.
"Please choose your-" The voice suddenly cut off as my finger rested on the choice that read:
'Warrior'
