In Red Hood and the Outlaws #27, we see something happening to Essence, Ducra's daughter (her death ?).
In this particular panel, we see her "death" or whatever is happening to her being felt by major characters related to magic in the DC New 52 Universe : Constantine, Apollo, a big space guy I don't know, Trigon and Madame Xanadu.
All of them seem stunned or not understanding what is exactly happening.
So, what is happening at this moment and how is this a major event for the magic-related part of the universe ?
