Krasue are evil spirits from Southeast Asian folklore depicted as the head of a young and beautiful woman that floats at night with her internal organs hanging below her - she is a vicious creature driven by extreme hunger and thirst, active throughout the night until she must return to her body by daylight : during the hours of day she will wander among the local population as a normal human, albeit with a tired expression.
Krasue are believed to be demonic witches who became cursed and thus crave raw flesh and blood, when neither blood nor raw flesh is available the creature will resort to eating carrion and feces, these grotesque habits cause Krasue to spread many vile diseases and they are prone to stalking pregnant mothers so as to try and feed either on the newly born infant or the placenta, using a long tongue to either lap at the placenta or even steal the fetus from a mother before it is even born.
To prevent such evil acts many locals would put spiky plants around their homes, discouraging Krasue from straying close and shortly after birth they would bury the placenta far from the village, believing that doing so would also deter the spirit from stalking the area.
Krasue could often be found in areas already haunted by the male spirit known as Krahang - if she were to be separated from her body when the sun rises she would be doomed to a painful death, likewise if her body was destroyed she would suffer a similar fate : she was also weak to fire and thus her most common enemy were angry locals with torches and machetes, who would pursue her and destroy her body while she hunted at night.
Krasue could also emit ghostly lights, similar to those of the Will O Wisp and more modern depictions often have her with large canine fangs, akin to the Western vampire.
While seen as a legend there are records of Krasue even in the modern era and some have even made it to local news - this has elevated the monster further into the realms of cryptozoology and urban legends.
