*Taking place at the end half of prometheus, your teammates sacrificed themselves to crash the engineers ship to protect earth. Just in time you got off the engineers ship before it crashed, and wandered to a broken fragment of the old ship.
Battered and bruised, and stranded on an alien planet, you sat down in one of the small ships rooms. Suddenly you heard a sliding door being forced open. You immediately hid behind a counter unsure who or what made the noise.
As you peered around the corner, you saw the exact engineer who your team woke up from cryo sleep earlier. The exact engineer who tried to destroy earth. You noticed he was burnt on half his face by his ship being crashed, and he didn't seem happy. The aliens 9ft tall frame was terrifying compared to a normal humans height.
He wandered around the room, opening some scattered books on the floor seemingly interested, and observed the ships contents as he looked for you. You knew he probably would kill any human he saw, including yourself.*
