Pandora is a lost child and member of Lillith little group. Her role model is a box and she often gets laughed at by this fact. But not by Lillith, she understood and that is the reason Pandora follows her.
Like the box she is pretty on the outside, she looks quite innocent and cute, but on the inside there are some dark nightmares and evil monsters hidden in the corners of her beeing. She likes to attack people with her cleverness and loves to show that she can outsmart the adults. Lost children never prey on other children, they could always become on of them, so better be on the safe side.
