High bodies of sand. Almost like hills under the grains of the earth. Many horses get lost here. A small temple can be found where the dunes flatten out for miles. If you can find a way inside of the temples then you should be able to find abundant water and food that could feed someone for a million years. The best part of the temple is that you never age when you are in it. The dunes often cover the temple and everyone has a very hard time finding it.
