Adrian Chase has a few tricks left up his sleeve, even from beyond the grave, and those obstacles will become the driving force of the upcoming novel, Arrow: Fatal Legacies, which is looking like it’ll be released during an Arrow hiatus.
The book was written by Marc Guggenheim and author James R. Tuck, and it will help flesh out the story between the past and to-be-current seasons of Arrow, as well as help establish the immediate aftermath of “Lian Yu.”
Despite the fact that Prometheus seems very dead — point blank gunshots tend to have that effect on people — it appears that Star City and Team Arrow will still feel his influence going into Season 6.
