the next Halloween related life-form on the list is the ghoul! I don't know about you but i think they are quite interesting. The ghoul is an ancient Arabic folklore and has many characteristics similar to a zombie or undead being. most of the differences are probably visual, They are said to have black teeth and skin which is tainted silver, and does not rot like an ordinary zombie. Like zombies, they have a morbid obsession for death and are known to hang around graves, and eat flesh. It is believed that ghouls are created by vampires. there are many types of ghouls, but to keep it simple, they are divided into three main groups: Vassals, independents, and reverends. Vassals are ghouls who serve for a vampire, and most likely the one who aided them to undergo change. Independents are quite self explanatory, but if you don't know, they are Solly independent. Reverends are ghoul clans who have a steady and efficient society.
Sadly all the images i found of ghouls were really boring, and so i wont bother posting one.
