I have been a huge fan of your work forever! If it's not too tedious, I have just a few questions I have always wondered about.
1) Just out of curiosity, would you say that after you became involved with W.I.T.C.H., the series' "magic system" more or less followed similar rules to Gargoyles and/or Young Justice?
3) In W.I.T.C.H., I have wondered how Elyon and Lilian became or were born the "Hearts" of their world. With Elyon, I have always assumed her parents perhaps blessed her with this power after her birth, passing/imbuing the Heart of Meridian's power to her, but I have always wondered about how Lilian was the Heart of Earth and, given the she didn't always exist, did Earth have a prior source of mystical energy? Likewise, if they perished, what would happen to the power they possess - for example, would they maintain their status as their world's source of mystical energy even as ghosts?
2) Also, is there a particular framework of magic you created for any given work that you personally prefer or are especially proud of?
