Hungry Ghosts

Wicked people will be reborn as a truly terrible night creature called a Preta, the archetypal Hungry Ghost. These beings are the tortured spirits of once living people who are made to suffer greatly with an insatiable hunger usually for something disgusting. And for some more unfortunate Preta, it can be a desire to eat their own flesh. There are many different types of Preta with each one the result of a specific type of misconduct such as being too stingy or taking advantage of people during the time that they were alive as auriold.
Preta or hungry ghost can generate from lack of care for ancestors or families being wiped out violently, like it happened to Soyou. Indeed their manor is crowded with these spirits and Hae can see them all.

Pretas rarely directly affect auriolds, usually invisible to the living they seek an end to their suffering by attending merit making ceremonies at temples. When a Preta has accumulated enough merit they are freed from their Preta status.
