"You know, Rn Rarak, that the universe is composed of great clusters of suns, separated from each other by billions of light-years of space, and that our own sun is situated at the very edge of our Galaxy. Beyond lie inconceivable depths of space never crossed by the ships of the Federation fleet or by anything else. Three weeks ago, however, our astronomers discovered that a gigantic dark star is approaching from that relam of infinite space, racing toward our Galaxy at an inconceivable velocity."
