The soulless are enemies with the lumens (creatures with glowing eyes). The soulless are lumens who lost their light to extreme depression, saddness, anger, and other bad feelings, so they pretty much give up on life and become soulless. The soulless are bone skinny sun deprived creatures that are pretty much hollow shells of their former lively selves. They can only get around by night cuz of their pale skin, and they can stand on their hind legs.
