It's been fifty years now, since first contact. When the Cordis arrived, many believed that it would be the end of the world. How wrong can one race be? We soon discovered that they were simply one race amongst thousands, who had a policy of non-interference. What this meant, was that any given civilization had to have reached a certain level of technology, before they were allowed into the planetary alliance. The Alliance was made up of Type One, Two and Three civilizations. We were Type One, in that we were now able to visit other solar systems. Type Two civilizations were thousands of years ahead of Type One, but were still tied to simple interplanetary voyages. Type Three civilizations were masters of the universe. There was nowhere that they couldn't go and nothing they couldn't do. We very rarely saw the Type Three aliens as we held little interest for them. I'd learned all of this at school alongside other aliens, so for me at the age of eighteen seeing aliens walking around on the street was simply the norm.
