While the characters might not know of all the places marked on this map (such as the Gates to Yu-Shan or Kether Rock, a Cult of the Illuminated Training ground), this map is a fairly complete look at many of the canon locations in Creation.
You can see the starting point of this game at the red dot with the red text saying "Home Manse". It is almost directly south of the city of Yane, in the Southern Threshold. The game will focus there to start with, but where you guys go from there depends at least in part on what sort of objectives you pursue and what you want to achieve. Obviously those objectives may change as time goes on.
You should be able to right-click on the file and save it to your own system. The map is actually pretty massive when it isn't shrunk down to fit the forums. In fact, you'll probably have to save it and look at it yourself if you want to see the actual city names and all that goodness.
