They're little demon-like creatures that can turn invisible. When they touch an object with coursing blood, their skin becomes visible, and the stronger the ghoul, the more they can control of what becomes visible. They eat humans, large animals, and mangos. In places where mangos are readily available or grown, shrines and offerings are made to keep the ghouls happy and fed. __ Feel free to continue this with your own drawing of what you think ghouls look like !!
