Death by dehydration is not quick. For some unfortunates, death comes not from thirst, but from sun burn. Too weak to move, those who collapse suffer terrible injuries to their exposed flesh before the oblivion of death comes. Some monstrous races, especially orcs, stake their victims in the hostile desert. They give their captive just enough water to survive, preferring to let him die an agonizing death as his flesh sears. In rare instances, the soul may be bound to the body by the victim’s desire for water. Other times, a fell spirit finds the blistered corpse and infests it with unlife.
Sun burned appear much as they did in life, save any exposed skin is covered in deep burns and unsightly blisters and their eyes are milky white, blasted by the intense rays from the sun. The latter has not diminished their ability to see. Sun burned radiate constant heat. The intensity is not enough to combust nearby materials unless the creature touches them.
