A Monochromatic Adventure

The drought was terrible. The Sun God demanded a sacrifice and the High Priest understands that this is the only way to appease him. You were chosen randomly. A sacrifice by dehydration was the most effective way to beg the Sun God for water from the skies. Everyone knows that this is the highest honor one can attain. You’ll be blessed in the afterlife! …However, you are not quite sure about that. To be honest, you are not willing to have your life ended and you are determined to do whatever it takes to escape this fate.
