Amelia and a gypsy (who I haven't named yet). In the story, Amelia meets a gypsy mystic at the carnival who shows her the Ouiya board. Amelia doesn't believe it works until the woman begins talking to the demon Ephialtes while trying to communicate with Amelia's aunt, Claudia. The demon takes advantage of the woman's spirituality and latches on to her. Because of an untimely decision made by Azriel, Amelia's fate is bargained by Ephialtes.
Remember the Aloadae, the twin giants? If anyone has any questions regarding the story, feel free to ask!
I have never played with a Ouiya board but they creep me out after watching all those paranormal TV shows!
