I've described this in detail before but it always seems to have gotten lost in the vilifying of my personality.
Regardless:
- WLW comes out in 2012.
- Following which Bakker maintains publicly that he is working on *one* draft titled The Unholy Consult.
- I received a draft of something titled The Great Ordeal and I opened that manuscript originally on camera with Wilshire and FB before we recorded the first TSACast.
- We are notably confused about the title but continue on with our Casting ambitions without my having read TGO or taken notes.
- Two months later (Summer '14), I go spend some time with Bakker after having both read the draft and done line by line edits and overarching thoughts (I always say 23pgs but I think that is literally mundane errors with 5 more pages of plot/narrative/continuity suggestion - none of which is ever fixed in the final edition *because Overlook*).
- Important: This is the point that he reveals to me that he's been writing two books simultaneously for over a year and a half already and apologized that he couldn't have The Unholy Consult draft ready for me before his submission of *both* drafts (clearly my head exploded at this point thinking that Dagliash was the end of TAE, which I had already spent two months digesting as the end of TAE, TNG presumably bringing the fucking heat).
- His publishers don't know about the split at this point - and Bakker has talked much about his bad faith move on TPB over time - and thus I'm sworn to secrecy regarding discussing my impressions of TGO "as the last book in a trilogy."
- Shortly after that meeting, he extended me the trust to discuss my impressions of TGO online without discussing the split books but never ends up once speaking publicly about the split until almost Oct '15, after issues with his publisher are resolved. TGO is released Summer '16.
- I finally saw the draft of TUC August '16 and send many pages of notes back in Sep (which famously again get *Overlooked*), following which Bakker and I sit down again for a post-TUC meeting. At this point the draft has already been looked over once by Overlook.
- TUC is published Summer '17 and Zaudunyanicon (arguably the last instance of any news) happens August '17.
As per what's in the drafts I saw at those times vs. what ended up in the books, there isn't really much difference. I know that in some instances continuity/pacing inconsistencies I noted in both (and Wilshire and MG noticed in TUC) were ignored by the outsourced Overlook editor (Bakker had told us at Zaudunyanicon that Overlook hired an outside contractor to edit TGO/TUC after the departure of Bakker's familiar Overlook editor circa. beginning of year 2015 - apparently unrelated to Bakker's sudden reappearance to touch base with the publisher).
In the Zaudunyanicon/Nascenti threads, I know a few of us draft readers discussed the cut Seswatha parts from TGO and TUC (the lengthier versions were definitely cut from TUC) as well as pacing issues with the Ordeal/Scalded/Proyas Chapter early on (which included a big chunk of narrative describing Kellhus/the Mandate's plan to have certain Mandati not eat the Meat and starve themselves but then got confused by the editor with the passages later regarding Zsoronga belonging to a congregation of those don't eat the Scalded).
This having been the longest post I've written in almost two years, I'll leave it at that for now (and for fuck sakes are the forum functions fucked up).
Truth be told, the publications of TGO/TUC were riddled with complications. Which as we know is a damn shame. But ultimately, I think Bakker waiting so long to explain to fans *the split* was the first and possibly inevitably fatal blow regarding execution and reception.
EDIT: Also, final thought for now, as MSJ said, Bakker was public about the arbitrariness of the splits since an interview with Pat's Fantasy Hotlist circa. TJE. He treats TAE as one book and just makes random "snips" that he thinks worked. I think he did quite well with TGO and I'm of the opinion that WLW and TGO are actually two halves of one book mirroring TWP. TUC itself almost perfectly mimes TTT without the TGO portion.
Again, it all comes back to Bakker probably unintentionally misleading reader expectations.
