Qandisa is a terrible Djinn or Demon, according to Morrocan mythology. Her usual appearance is that of an attractive woman, though she is known to be a shape-shifter. Apparently, she was once the Goddess Of Love but after falling from grace she became an enticing sinister woman.
She entices youn and naive men into the rivers and streams that she inhabits, and those who do follow her are never seen again.
Sacrifices and offerings are made to her at the time of the Summer Solstice in certain parts of Morocco. By doing so these people believe they have appeased her and will be safe from her.
