It was announced as one of the DC YOU titles to launch in June, written by Alisa Kwitney with an artist as yet unallocated.
It was one of the two titles announced still unseen. Dark Universe saw its creative team of James Tynion IV and Ming Doyle leave the book, with no news about the book's future – except that it now probably doesn't have one.
But as for Mystic U, very little is known. Aside that, from the title, one could presume that it was a university of college for DC Comics' characters of a more sorcerous and youthful nature. Tim Hunter and friends.
But I understand there was a creative and editorial logjam over what was expected from the book after it was greenlit. And no party seemed to come to any agreement over what was wanted and provided.
And so, while technically still on the books, month after month of solicitations have come and gone without a first issue bothering the schedules.
Will a new year finally bring a first term for this series?
