Well as you can tell the Grand Desert of the South is a Desert that is Grand and is in the South. It has many dunes, pits, The Now Endangered Desert Penguins and Desert Dragons. When you travel to the desert don't bring water walk ten miles Northwest (Don't Complain in Ironman's you have to run 11-20!) and there is the Pit of requirement. Go aroung it 3 times thinking of what you desire (don't just think of water) and then jump in the pit and it'll take to that place, let's say you need the bathroom once you go around 3 times and jump in the pit and then there will be a bathroom.
