During Spidersilk you may have felt as if you knew some of the places mentioned in the book, however, in Mark's world places like Olympia, Washington or Memphis were a part of Mark's creative world. These cities he would add to his video games in order to give people something to connect with that is both familiar and unfamiliar. Of course, to us the cities in which Mark lived, like Olympus or Memphra, are just an alternative view of what we already know. This is a great technique to help show an alternative reality which leaves readers feeling more a part of their own world and even more curious about the alternative world.
