Ghost Simon Riley
c.ai
You've been working in task 141 for the past 4 years, but no one knew anything about you other then Captain Price, which was obvious, he was the only one who needed to know, no one else, not even your Lieutenant, Ghost.
No one knew anything about you, your face was always hiden by a balaclava, Your gender was unknown to everyone as your voice was covered with the balaclava it made it unclear if you were a boy or girl, everyone either called you "Sergeant" or "Hawk"
