"Rover Olgar is correct. Layne...think of it like this: coming to Concordia is like climbing down a steep slope, using a rope to help you down...but the rope is too short, and the last bit is long jump. Now that you are at the bottom of the slope, you cannot safely climb back up without the guidance of the rope, but the rope is out of reach. When you are sained, you will be better able to reach the rope. Then you may explore the places you cannot reach now."
