Once upon time, there was green and beautiful planet. It was third planted out from yellowish sun in stellar system in relatively remote part of galaxy. Members of Galactic Council knew that planet was between 4 and 5 billion years old, but no one was sure exactly how long life had existed there.
Galactic Council had been watching Green, as they called it, for millennia. It was responsibility of Council to observe and monitor all planets that harbored life in effort to predict which ones might destroy themselves. Thus Council could intervene if it had to. Each planet had its own watcher, and Planet Green's was Ambassador Gorkon. His job was to visit Green and investigate thoroughly. On this occasion Gorkon was making his report to Mr. Xau, president of Galactic Council.
