Nelos Llothry's dialogue topic kinda contradicts what he has to say previously when you try to rectuit him
Talking to Nelos Llothry about "Nelos Llothry" you can convince him to rejoin the guild, he then proceeds to say that he has a hunch as to why Ethalvora wants him back "I have a hunch as to what that research his"
he then asks you to retrive his notes, with the dialogue topic "notes on hyperbolic tesselation". in this topic his hunch turns into certainty "I need my notes on this subject to assist the Guildmaster with her latest research"
I really liked this dungeon, it's difficult to navigate (in a good way), the enemies are well placed and the three things you have to repair complements the challenges of the dungeon itself
I just have a couple of points that I think could make this dwemer ruin even better
When seeking advancement to Wizard in the Mages Guild the player needs a Wizard's Staff. Mainland guild members will still direct the player to a cave near Dragon Fel, which can be ludicrously far away for them to have heard of (in-fact, the vanilla dialog here doesn't actually mark Dagon Fel on the map, making it even more absurd for people playing characters that never step foot on Vvardenfell). This seems like a simple place to add another "free" Wizard's Staff for the player to be directed to if they seek advancement in a guild on the mainland (or at least southern mainland.
The quest for general Casik (Belated Justice) and the one for Bera (The Exiled Duke's Affair) result in very similar rewards
The main NPCs from both quests reside in the same cell (Old Ebonheart, Legion Dungeons) and both quests reward the player with an amulet that increases personality and/or speechcraft
There are more items in TR that have similar effects, most of which are amulets
here's a longer list of kinda similar items, the first two are the one from the quests in OE dungeons, the first four items are amulets:
Whole goal is to get Staron out of the town so Ordinators could get him. He can be lured with command humanoid in vanilla game. There could be proximity trigger for such resolution, skipping whole trickery with intervention scrolls.
Talking to guards with punavit in the inventory gets it confiscated. This is normally fine, but it creates a problem in Bounty: Turedus Esdrecus where it will lower the reward, which is rather odd since the the theft is publicly known and you've been explicitly tasked with getting them back. While this quest is active and Turedus Esdrecus has been killed, guards should instead express relief at their retreival and give you directions to Indoril Ilvi (generic town dialog otherwise doesn't state where in town he is).
After finding the prince, Iron-Claws says he will wait with the Alfiq while I go back to the prince's brother, but when I returned to the mission, Iron-Claws was already there. I think I exhausted the dialog options that were available to me with the Alfiq (I was playing a Khajiit so I was able to communicate), but I didn't give him moon sugar. Still, Iron-Claws insisted he would stay and watch over the prince so it was strange he was back in the mission before me...
In vanilla, all of the blades trainers, in addition to offering helpful advice to the player and sometimes some items, all also have unique responses to 'latest rumors' that expands upon their personal jobs/tasks within the blades organisation.
This small bit of flavour text goes a long way and is missing, at least for Idra Uvalen in Firewatch and I suspect the others. Is a great way to give a little bit of context, depth and background information on the goings on of an area.
