Russ, the first sentence for the synopsis of Death of the Author should be 'at a remote manor,' not 'on a remote manor.' I feel embarrassed I missed that, considering how many editing passes I took.
Nnesk, Death of the Author is the intro adventure for the upcoming Adventures in ZEITGEIST setting book, which advances the timeline to twenty years after the Gears of Revolution adventure path.
I think the plan is that now that the 5e conversion of the adventure path is done, we're going to start soon on layout for the adventure. The vibe I shot for was that of an Agatha Christie novel, though this being D&D, naturally there's a bit more action and monsters involved.
