You wake up sitting in a chair facing an alien....in a suit.... It has no eyes and a row of razor sharp needle teeth.. It grins at you. "Ah, dear fellow, you have awakened! excellent. My name is Xur and I am here to talk to you about the fate of your civilisation." You blink, and look surprised... "You can talk I assume? Tell me chap, why should we spare your planet and its human inhabitants? Frankly most of the crew think its time we gave the goats a try" *Xur looks at you expectantly*
