Main content that is cut and reusable is voiced lines, extensively so compared to the Bioware modules. Some assessment of what is included in Shadows of Undrentide voice line wise.

From the looks of it several sets of quests and lines were cut, what a shame! It also appeared that the "Interlude" was chapter 2 and chapter 2 was at some point chapter 3 (see the "_temp" area, where a sign says "move to chapter 3" found in the Interlude module file) - likely most of the cuts are to the interlude and chapter 2.

Module/Plot/Level Cuts

Most of this is pieced together from the voicesets/voicelines and some random leftovers in the modules.

Chapter 1:

• Mischa Waymeet the Paladin was a 4th completely cut companion. She is evidently setup as one in the module, and the voicelines have a ton of quest and discussion voices.
• Uppsala a female Frost Giant was involved in chapter 1 most likely. Possibly the polymorph potion making you into a frost giant wasn't part of the design until later when she was cut? Implied to help once items are returned.
• J'Nah has incomplete voicelines (buggy/cut off) that implied some further quest related to her Gnolls

Interlude:

• Katriana has a full voiceset (so possibly at least temporary companion?) and cut voicelines about travelling and possibly being captured. Therefore the plot in the interlude may have been quite different.
• Assam has a full voiceset and may be a temporary companion; possibly was Interlude and Chapter 2, since mentions the madusa.

Chapter 2:

• Archmage Leomund (maybe the Leomund) has a full voiceset (possibly a temporary companion?) and lots of cut voicelines and never appears in the game
• Heurodis mentions a Race to master the North/South/East/West winds, and dying means she gets resurrected. Some other voiced lines references the Elemental Winds too so a big cut portion there.
• Corith and Malthia Drammar would have been present since Heurodis is named.
• Cskikil the Shaman of the Seatung Tribe may have been present in this chapter and wanting their mate to be rescued.
  • These two groups also mention the "four winds" needing to be mastered.

Voicesets

These are the SSF voicesets and what they're used for, if anyone. Not listed here is any PC voicesets included in SoU.

Since voicesets are commonly tied to voicelines, it'll reference them and we'll carry on that work further on.

Voicelines

Note all of these are cut content but some are included here for completeness especially if referenced by other NPCs who were cut (eg the Asabi are referenced).

Note the voicelines are not in the TLK file usually, so they won't have proper subtitles so some guesswork is involved in the transcripts.

Asabi Thrall vs_nx0asabm

Asabi slaves in chapter 2. Has partial NPC voiceset.

Ashtara vs_nx0ashtm

Slave owner in chapter 2. Has partial NPC voiceset.

Assam Al Jurdi vs_nx0assmm

Assam. A cut NPC - or at least temporary companion? Presumably from the Interlude onwards (maybe it was once longer and not just an interlude but a full chapter 2 of 3). Most likely due to mentioning the Bedine who appear at the Oasis of the Green Palm, he'd first appear there.

Potentially he's been replaced by Ali Ibn-Musud who does take his portrait but doesn't actually do a lot except talk. The fact that Assam meets the PC several times implies a completely scrapped set of quests/areas or that they just followed along like Deekin/Dorna/Xanos did in the caravan (or the caravans destinations).

"Maneaters" and "Asabi" are mentioned as well as "the medusa" so presumably went into the final chapter.

Reused for PC voiceset "Human, Male, Desert Warrior".

There are no TLK entries (except for his voiceset) so nothing but transcriptions for his voicelines.

Ayala vs_nx0ayalf

Ayala is the harper in chapter 1, who of course doesn't continue with us. Her voice lines are all used so there's no cut content here.

Corith Drammar vs_nx0cortm

Has voiced lines 50 through 59 totally unused.

Mentions a the tower, and seems to be either stuck, injured or whatever outside of it (in the ruins) and a puzzle involved in it ("mastery of the four winds").

"You stand in the ruins of the great citadel of Undrentide" means probably Interlude or Chapter 2. Also mentions Heurodis so knows about them as well.

"Elf, Male, Wizard" in toolset. Seems to have a likely portrait el_m_11_

No TLK lines so these are transcribed.

Malthia Drammar vs_nx0maltf

Corith is her father and presumably a questgiver to go save him (unless you find him before her).

Voiceset is renamed "Elf, Female, Noble" suggesting they were an elf. Matches a portrait quite accurately see below. 50 - 67 voicelines so quite a few.

May be to do with the Winds race. Takes something for safekeeping.

Has a full voiceset. Suggested to be a Mage instead of a Cleric with some of her voicelines. The full soundset could mean they're a temporary (or permanent) companion.

The plot outline for Malthia and Corith could be:

• You find Malthia 
• You rescue (or don't, quest ends/Malthia attacks) Corith
• You get involved in the Winds race and they help
  • Possibly involved in a rather bigget fight to stop Heudrolis getting to a particular wind - certainly can teleport or similar to get ahead of her in one case

Cskikil vs_nx0csskf

Name taken from the unused portrait filename.

Unused female NPC for snake/lizard-like people. Floodgate or Bioware reused this voiceset for a "Medusa" which isn't quite right since her attack lines mention the Saetung Tribe. Might be worth redoing the Medusa SSF to be just her non-specific lines or just attack noises like other monsters. Funnily enough her original voiceset line was made into "Medusa, Handmaiden" and another one added for just "Medusa".

Cskikil is "Shaman of the Saetung Tribe". Is a healer. Has a portrait see further down. Not sure if they even have a model to be honest. Snake person of some kind?

Has a mate "Tarnical" (sp?) who apparently you can rescue.

Wants "the blood of our sacrifice" which is vague. This might reference 

"Those who once dwelled here named this city Undrentide" so likely Chapter 2.

Deekin, Dorna, Drogan

These three have all their voicelines used, nothing seems to reference the four winds.

Belpheron's Construct vs_nx0headm

A set of golems created by Belpheron (who is the mentor of Heurodis, and also makes a cameo attacking the player in Cania in HotU). According to voicelines and the naming of the voiceset they are only heads. There are 3 of them and it seems you were meant to defeat (or in one instance let them go to sleep). Due to the same voiceline for all 3 heads, it could easily be made so that they all can be encountered in any order.

It suggests they were mere heads but presumably had some power to reform and/or attack the player by implication of them defending themselves. There's no specific new model in SoU for golems mind you. In this case having a hovering golem head might be quite a fun way of doing it - a massive head from what would have been a crazy big golem.

There also is no obvious area they'd be in - but it could have been some offshoot of the main area as either harder content with a mighty treasure reward (and some more info on Heurodis' plans) or even a potentially necessary step given Drogan mentions Belpheron directly.

These constructs would be from the Interlude inside of Anauroch due to mentioning it directly and Drogans lines.

• Note: There is a Shield Golem there, and they guard a corpse which was a modified Lich (so has the same description, but the appearance and name is changed to Skeleton) - which suggests a remnant of this idea of sorts.

The toolset name of the soundset "Lich, Mage" is off - it should have been "Belpheron's Construct" since the voicelines do refer to repairing and Belpheron in the third person - odd how it was named that way.

Drogan references Belpheron in the interlude:

82885    Our enemy is a powerful sorceress by the name of Heurodis. Little is known of her personally, but we do know that she was once apprentice to the dread lich Belpheron.

82886    Belpheron had spent all of his extended lifetime learning of ancient Netheril and its artifacts, and he passed this knowledge onto his apprentices. The Harpers thought all of Belpheron's students were killed when he was. Apparently they were wrong.

82887    But now we know what this Heurodis is after: she desires to obtain the power of the ancient Netherese mages for herself. Power beyond any magic practiced since the Empire's fall.

82888    This is why she seeks the mythallar... and why she has come here. With Belpheron's knowledge, Heurodis is more than capable of attaining this goal.

Heurodis vs_nx0heurf

She's got a lot of voice lines. A lot. 50 through to 98. However only some of them appear to have references in the TLK file 50 through to 66.

There is a huge amount of cut lines for the final Chapter 2. It was going to be a lot more involved.

Of particular note is the Winds race (the winds being "winds of magic" it seems). This is evidently in Chapter 2:

• Mastery of the North, South, East, West winds (is po_dwind_h.tga related?)
  
  • "Useless Trickster" on the West wind delaying her
  • A trap! (076) haha
• Suggests a race with the player to master them, and the player can get there first - to all four in fact - and either gain an advantage over her final boss fight, or she gains an advantage making it harder (Essentially the same thing tbh)
• She summons 4 winds at the end of it to attack the player (pre-boss fight maybe)
• Can kill her and they keep raising from the dead
  • Noting that she was transformed into an Undead Medusa wizard at some point between turning the player into stone and these lines - all the cut lines are in her "undead" phase of "life"

There is in the final game the areas "Temple of the Winds" where you race up to see her at the top. Possibly this entire bit was either part of the existing level design (her just teleporting around being annoying or somesuch) or it was basically all cut for time and the areas we got were not what was intended.

J'Nah vs_nx0jnahf and vs_nx0jnah2

J'Nah controls the Gnolls, and obviously just betrays you, no other options in the voicelines alas, but it does imply Chapter 1 was always the most complete of the 3 and contains fewer cuts.

Katriana vs_nx0katrf

Katriana the camp mistress. Lines 50 through 79. Only 50 to 69 are used and in the TLK file so 9 are unused.

Voiceset is partial on the SSF but can be made to be a full voiceset easily enough (would be good for PCs). Looks like it might also have the full voicelines in the TLK file too. See lines around 76064.

The voicelines 70 to 79 look like they are for a caravan to Miyeritar? (or something like it "Mar-ya-tar") Including pay? Bit confusing. This implies some significantly cut content though. It seems:

• There was an additional stop after getting Garrick which was a caravansary (trade post)
  • You left the caravan at this point
  • You'd probably still have ended up finding Heurodis who turns you to stone, but it wouldn't be just a hop skip and a jump after by teleportation.
• At the caravansary you see/hear her getting captured (or are actively involved somehow?) and can rescue her

May have also been captured with lines ending in 79 and can be released. A bit confusing though.

Leomund vs_nx0leomm

This Leomund?! https://forgottenrealms.fandom.com/wiki/Leomund (and yes it probably is!)

Has a likely portrait unused in the campaign since it was included in SoU and looks very NPC-like (hu_m_36_).

Alas no TLK lines referencing the man. It suggests he's a planar traveller so could fit in sort of anywhere.

Mentions the item "Thermolabe" or similar (frankly can't place the name, voice line 53) and looks at a "shard" and mentions knowing Drogan.

Infamously this voiceset is marked as Human, Male, Blackguard! It's also really a full one that can be used for PCs or Henchmen.

The cut content probably fits in Interlude:

• He's found in Mordenkain's Magnificent Mansion or at least a portal to it (or coming out of it in a cutscene might be fun)
• He's researching Balpheron's ruins and/or trying to find his lair (or will help the PC do so since their goals match)
  • IMO to show off he's a real archmage either you are seeing him in his mansion (and so he doesn't do legwork defeating monsters) or he has to open some door or magical protection seal and can't enter without being then trapped (because the seal would reform and he can't open it from inside). Either might work for hm.
  • Might tie into the Belpheron's heads as enemies.
• Once finished he might well give some information about the mythallar shard you have with you
• I guess easiest thing is once the research is complete (ie he's got enough from Belhperon's place) he exits stage left before the whole thing goes upside down ("Why didn'y the archmage just kill Heurdolis" kinda thing).

Mischa Waymeet

See Overhaul Mischa Waymeet. She's basically a proper henchman and has her own quest.

Tymofarrar vs_nx0tymom

This is J'dah's "ally" who betrays her. No extra voicelines so looks pretty complete but wonder how he'd interact with Uppsala. Anyway just needs voiceset properly adding.

Uppsala vs_nx0uppsf

Is why a Female Ice Giant was added to the game. Is in their own fortress. Chapter 1 most likely since she's not in a desert after all. Looks like their ssf file (vs_nx0uppsf.ssf) is named "Half-Orc, Female, Baroness", even though it mentions Jotunheim which is a giant thing.

Note there is a single leftover refrence to "uppsala" in the modules and that's for "UppsalasMark" item in xp1_checkupmark.nss in chapter 1 of course. So someone added a conversation to check for this item but later removed it.

Quests it seems:

• 3 way involvement with Tymofarrar and J'Nar it seems (1 item each?) mentions J'Nar kind of in line 60.
• Obviously could be just defeated for stuff
• 2 Quests given out:
  • Looking for an amulet from a "ink stained little meiser"
  • Getting an axe from a barrow
• Then presumably can help fight Tymofarrar

Going on a "Barrow Raid" for an Axe.

Helps against Tymofarrar if you do her tasks. I wonder if the items were hers and they were stolen from her (by J'Nar? it implies if you talk to her first, she sends you to kill her for something)

Looks like it could be implemented. Her portrait suggests being in a human village.

Could use a tweaked model - the Frost Giant, Female is obviously her but with a helmet and slightly different legs. c_gntuppsala.dds texture (used on the frost giant female model) suggests it could get some more chainmail. Or just use the frost giant female as is, it's not that bad.

Xanos Messarmos

Has one additional line not in the TLK file related to the Winds quest. Seems henchmen were going to say something about it as well.

Portraits

There are several unused portraits that were intended for specific NPC characters. Some were made available to PCs and some were toolset only content.
