For some reason I thought Harold had reason to believe Renne was dead but I don't know if I made that up in my head to explain his actions. While I don't think the full truth about the DG Cult ever went public I think enough of it did that if Harold knew Renne got taken by them (and I'm pretty sure he did) and
wasn't
returned by the guild/government after the suppression operation that was a pretty grim sign.
May you find your book in this place.
