I was made aware by Torlof of a discord post by Infragris that had some additional information on the claim - I'll post it here in order to collate all relevant claim information in the one place for ease of reference:
The NPC listing for the TG was never finished. Just ignore it for now and assume that there will be 8-10 NPCs in that interior.
The basic concept behind the place is the same as TG hideouts in Vvardenfell, like the South Wall Cornerclub, Dirty Muriel's, or the Rat in the Pot. The South Wall's "People" tab is a pretty goo guide: there might be two or three normal patrons, but the rest are at the very least on the Guild's payroll, if not outright members: https://en.uesp.net/wiki/Morrowind:Sout ... Cornerclub
. If you check TG guildhalls in Morrowind, you'll notice that they aren't really "hideouts", and that most business seems to happen in the open. You can sort of nod to that, but since we have the space a couple of private backrooms are not a bad idea. The difference between the Vvardenfell guildhalls and this one is that the Guild is very powerful and well-established in Cyrodiil, so it can afford bigger and better digs.
In general, I think one "open" public room, a couple of backrooms set up for illegal gambling, and some more TG-exclusive rooms on the top floor. Maybe set up the interior so that you have to pass one guarded door to reach the backrooms, including the upper floor. A basement/tunnel network would also be pretty nice, for storing loot and stuff
Actually come to think of it, original planning for that place was sort of inspired by the Thieves Guild level in the original Thief game, if you ever played that
which was a casino, connected to a large sewer hideout, which in turn connected to the lavish town houses of the Guild leaders
The idea was to have an underground sewer/tunnel/cave part starting from the Spearmouth's basement and ending in a lavishly decorated hidden chamber where the guild leader lairs.
I was modelling the interior in the vein of vanilla TG guildhalls which, as the discord post notes, mostly had things done out in the open - hence the fact that I was initially going to restrict the 'private' space to the 3x3 section alone. This will be changed to align more with the vision presented in the discord post.
-Interior layout completed, major object placement in parts of the interior. The interior space that corresponds with the exterior piece 'T_Imp_SetAnv_X_Building_05' has had its' size increased from 4x5 to 5x5. The initial plan for this space was to have it mainly serve as the general public inn space, with stairs that led to rooms for hire on the 2nd floor and doors in the back that led to the more private space in the 3x3 block. With the new info from the discord post, I've since partitioned this space between a section that carries the original idea for the space (public inn space) and a back section where gambling and other unscrupulous activities occur. The increase in size is to better accommodate this expanded function of the space.
-The 2nd floor will most likely have the rooms for hire removed; my initial plan was to have the 3x3 section serve as the TG-exclusive space, with stairs located in the front to provide access to rooms for hire in the 2nd floor - this clashes with the concept presented in the discord post which has most of the interior be effectively private and host to stuff the TG would rather keep out of the open. The reason why they are still there is because I haven't yet figured what they will be replaced with - likely private parlour rooms.
-The basement will still serve as a storage area for legitimate and illegitimate goods, as well as a secondary entrance via the trapdoor. One change from my initial plan has been to add a 3x3 section that will tentatively serve as the guild leader's office/quarters; it's not as elaborate as what is described in the discord post, but it will serve in the interim (I might change it in the future, but it's something I need to think on further, as I'm not really too sure how extensive I can make any sort of 'basement/tunnel network' as is mentioned in the discord post).
Things will hopefully be more settled by the next update.
