A corphal is a malevolent spirit. The Manatorians believe that corphals haunt the catacombs of their city, seeking bodies to possess, and thus they have their bodies preserved by taxidermy after they die, so that the corphals can't use them. When the kaldane Ghek was imprisoned in Manator, he exploited the superstitions of the Manatorians, using his various inhuman abilities to convince his guards that he was a corphal. Being accused of corphalism is roughly the same in the nation of Manator as being accused of witchcraft.
