A pronged trapezoid was the item used by Andraethu to further his powers of stealing souls, particularly those of children. Like Penelope's music box, the trapezoid is believed by some to be a Deceiver, and it causes insanity at the touch of a mortal. Andraethu succumbed to its power, and went on a rampage of murder, fulfilling parts of the Prophecy of the Wraith.
