Ghouls are undead creatures given life through the strong presence of Dark Ka. They survive by consuming the flesh of the living. Some ghouls also possess the ability to take on the appearance of those that they consume, allowing them to walk among humans for short periods of time unnoticed.
Ghouls generally gather in tribes and make their homes in subterranean area, usually near grave sites. The are nocturnal creatures but are capable of functioning in daylight if need be.
