Okay, I have understood for a long time that Festivia was actually adopted and she and her descendants are not real Butterfly, and reveal that Festivia was a folk foot, so her descendants including Star and Moon are also.



But my question is, was it really a coincidence that Moon ended up on Pie Island? Of all Mewni, perhaps the progenitor of magic realm had every intention of sending Moon to the place where her roots came from? When she said about Moon "she should not be here" she did not talk only about magic realm?
