The Amethystites are oofas that believe in gods within the floating purple gems (amethysts). They try and collect them because their belief is that once you have enough, you can become blessed and go to Fayjerusa, or heaven for them. And if they cannot collect enough, they go to Guocusa, or hell for them. Most Amethystites are criminals and have been put in jail for trying to steal amethysts from Emperor Zoofusa.
