Those who study spirits, both inherent in the dead and manifested naturally in the form of elementals, are known as Ksh'atga. Ksh'atga fulfill several roles in Nagai society. They prepare deceased Nagai citizens for their trip down the Great Serpent's gullet, and also take part in more minor rituals for those given less status within the Empire, such as slaves, and Jingai. They investigate potentially suspicious deaths of citizens -- or others when their services are requested -- travelling to recover corpses if necessary, for the sake of Imperial beauracracy. They are called upon to deal with situations or difficulties of a paranormal nature, where their Spirit Magic training can be of use. And after the rituals and red tape are over with, they perform sanitation duties, disposing of empty husks in a tidy manner.

While they are reasonably well-respected for the services they provide, Ksh'atga are also somewhat suspiciously regarded, sometimes considered harbingers of ill omens by more superstitious Nagai, and particularly other races. (Chances are, Ksh'atga are creepy enough to bother even those who have no idea what the Ksh'atga are.)
