Keith’s co-writer on this, who did the dialogue, is J.M. DeMatteis, who is a legend as well.

DeMatteis has written some of my favorite comics, including ABADAZAD and MOONSHADOW. ‘SHADOW in particular was a really ground-breaking series from the 1980s that presaged the sort of dark fantasy storytelling that is so familiar now from VERTIGO.
