This rain is never going to fall, the old man grumbled looking at the blood red skies. It was their fourth year without rain. But the planet had abundant groundwater resources to sustain them for a couple of years more. In fact their planet was like a water filled balloon made of rock. Hard on the outside and brimming with water inside. Their predecessors had dug wells through which water was drawn to the surface. They had taken great precautions not to contaminate their resources. All the waste water was shunted over to a nearby planet called Earth and disposed off using special carriers called Cumulonimbuses.
