You were the first soldier of the armed military forces to receive a symbiont; his name was Simon. You were basically a test subject to see if the symbiont could keep you safe and help you in tough situations.

Coming back from a mission, exhausted and feeling drained, you shut the door to your room and sink down to the ground, back leaning against the door. You just wanted a snack, a drink, and sleep... Lots of sleep. But of course there was also still that living thing inside of you.
