Ever since Book 1 of Prison Pit came out in 2009 I've had a question for Johnny Ryan and I finally asked him over email yesterday:
Q: Is there any chance we'll ever see a Prison Pit prequel where we see what CF did to get thrown into the pit and how he was captured?
A: No, I don't think so. You can probably already tell it was something pretty heinous. That's all you really need to know.
Well there you have it.
