Alright, let's look over the Thorek section in a bit more detail
"Karaz Ghumzul rebelled," he growls, "and closed their gates to a Throng that went on to march with empty bellies and blunted axes to their doom at the hands of exiled Elgi sorcerers. And when the Time of Woes taught them the true, bitter taste of independence, they abandoned their Hold and sent their own starving children on a march across a ruined continent to beg for food and shelter from the Empire they betrayed while they used their riches to buy a place among the Umgi. Treason seems to be carved into the bedrock of those lands. Elgi, Dawi, Umgi, all seem to find treachery growing in their hearts in the shadows of those cursed peaks." He narrows his eyes at you. "I have marched into worse to seek the relics of the Ancestors, but the world has no shortage of cursed mountains filled with ancient woes. Even now a Throng begins to gather to right the wrongs of the Silver Road Wars, and each heartbeat I spend at the forge will prevent a drop less of Dwarven blood spilled upon Karag Agilwutraz."
We've been seeing the good side of the dwarves for quite a long time, and here is our long overdue look at the other side of that coin. Their inability to let go of a grudge has never really been a problem for us, as the Empire as a whole has managed to avoid getting any serious grudges against it as an entity. However here we see what happens when that's not the case. Apparently Thorek - despite being from a hold that's about as far away from Ghumzul as it is possible to get, that's been cut off for 3000 years - still harbour that grudge against Ghumzul, and from the way he speaks it seems almost personal to him. While this ugly side of the dwarves has always been there, I think this is the first time we've ever seen it come out.
"You have a price in mind, I take it." One that he does not want widely known, you would guess. That would explain why you're having this meeting here, far from any Dwarven ears except those sworn to Thorek's service.
"Two," he says frankly. "First, the descendants of ancient Dawi treason live fat, happy lives within Middenheim. There are many wrongs that must be punished before their own inherited sins are a priority for the Karaz Ankor, but they still hold the keys to Karaz Ghumzul. I need allies in the Empire to bring pressure to bear on them so they will surrender those keys, so that I might harvest a beginning of repayment from its ruins."
Most Imperial cities with a substantial population of expatriate Dwarves are very protective of such industrious and knowledgeable citizens, and Middenheim is no exception. Trying to bring pressure to bear on them would be politically fraught. But you knew that partnership with a Runelord as renowned as Thorek Ironbrow would not be cheap.
So Thorek's first price is to put a little pressure on the the Imperial Dwarves in order to get them to give up the keys to their old hold. Unfortunately, this likely has larger implications than it would seem. IIRC there have been periods in imperial history where pogroms against the Imperial Dwarves occured, and even when not activly racist the wiki tells me there's always a simmering resentment amongst the lower classes. This likely makes them not likely to respond all that well to the Empire putting pressure on them. Even beyond that, it could drive a wedge between the Imperial Dwarves, and the KA dwarves that might cause problems.
Further, I don't think our reputation amongst the dwarves will amount to nearly as much with them as it will in the Karaz Ankor. From what little has been mentioned of them, they see themselves as culturally distinct from the KA, and while our rep will likely buy us some amount of goodwill, it likely won't stretch nearly as far as we would expect. Further, as mentioned in the Nuln spymaster interview the Imperial Dwarves still get upset when someone tries to mess with their old fortresses - even if there isn't much let standing.
Because of the above factors, this will likely cause a seperation between the Imperial Dwarves, and the Empire leadership. This might amount to little - the imperial nobility is likely much more powerful and influential, so even if annoyed, an argument could be made that they won't rock the boat too much. OTOH, they're still dwarves, and they'll remember slights against them. And I doubt their price for giving up the keys will be cheap... If they are willing to give them up at all (and I suspect they will not).
Now, strictly we wouldn't be agreeing to get the keys or anything, just put a bit of pressure, but it's still something that will likely have consequences. Also, attempting to get a minority group to give up an important cultural relic, so some guy from a far-off land can pillage even more relics from the site of their ancestor's graves doesn't sit well with me.
Some of the steel goes out of Thorek, and he takes another pull on his ale as he considers his words. "The Waystones," he says carefully, "are a product of some of the greatest minds of the Golden Age. There are many who would say that there is no question that their workings would be considered secrets of Runesmithing, and therefore cannot be shared with anyone without the blood of Thungni flowing through their veins. But there is another line of argument, that this information was so intimately entwined with Zhuf magic that some knowledge of it must have been shared with the Elgi, and so it cannot be called a sin to share that knowledge without levelling that accusation at those that were taught by the Ancestor Gods incarnate. I look at these facts arrayed before me, and know that you are asking me to choose an interpretation of them that is favourable to you. So I would ask the same of you."
"Aye?" you say cautiously, running through the possibilities in your mind. Karag Dum, you'd guess, or Karak Vlag. Either the old scar or the fresh wound in Runesmithing orthodoxy.
This already tells us a lot about runesmith politics right now, and I don't like what it says. It tells us that a significant fraction of the runesmith's guild is against this on principle. This means that our pool of likely recruits is probably quite small from the dwarven side. None of those saying the secrets cannot be shared at all are going to join us, and likely even more will stay away because they don't want to risk the condemnation of their peers. Which also means that if we were to turn down Thorek we probably are going to have a difficult time finding someone with the knowledge base we want if we're putting our best foot forwards. Also that we might run into runesmith related problems as the project proceeds onwards.
"Just as you do for the Waystones matter. It seems to me is that Borek was ashamed but not surprised by what he found at Karag Dum. Which would seem to imply that whatever terrible deal they struck with Cor-Dum, it was a final resort that desperation drove them into. Desperation brought on, in no small part, by the schism in the Cult of Thungni, and the southern Runelords abusing their authority to paint Karag Dum as untrustworthy. And as such, when they faced the forces of Chaos, they did so alone."
"You once told me that you'd tear the Guild asunder if you knew for sure that that was the case."
"And your words would give me the authority to do so. Tear it apart and melt it down, that it may be reforged anew. Since we last spoke I have been travelling the Karaz Ankor, and everywhere I look I see so-called Runelords with beards grown yellow instead of white, squatting atop their secrets as jealously and uselessly as a Dragon atop a hoard. They fail the Karaz Ankor twice over, for in the absence of Thungni, Morgrim grows reckless and hasty in his experimentation as He tries to do alone what should be the work of two. I will correct this in time, but could do so in a more efficient and lasting manner with your testimony as a banner."
And here is the actual request number two. He wants us to imply that the split in the cult of Thungni was the primary cause of the fall of Karag Dum - which to be fair is certainly a plausible interpretation so we wouldn't exactly be lying. However we wouldn't exactly be telling the truth either, given we know almost nothing about the issue. And more importantly than the words themselves, we give Thorek the cause he needs to tear the guild asunder.
Now several things stand out about this. The first is his assertion that "in the absence of Thungni, Morgrim grows reckless and hasty in his experimentation". Now, it is probably a good thing to remember that Azul - and Thorek by extension - have been isolated for thousands of years, and as such haven't really been party to much of the Karaz Ankor's technological advancement. Enough that Kazador prefers crossbows and bolt throwers to guns and cannon. So while he's probably opposed to the more radical things that are going on, he - and his faction, which is likely mostly Azul based - might also oppose guns and cannons, seeing even those as reckless advancement. So this could cause larger problems if he is successful.
However we could also look at this from a different direction, namely the "Morgrim grows reckless and hasty in his experimentation as He tries to do alone what should be the work of two" bit. So even while he might oppose some newer tech, this might also imply good things about runic work applied to engineering. Thorek has proven willing to experiment with Anvils, so maybe his faction would be willing to experiment with things like gun runes too, to combine Morgrim and Thungni's work. Now granted, while Thorek has a different perspective to Kragg, he's still on the conservative end of things, so I don't find this too likely, but it could be something that follows if one takes an optimistic perspective.
Then there's how this effects the runesmith's guild itself. Thorek intends to change the operation of the Runesmith's guild, and unfortunately this will undoubtedly run into the stubbornness of dwarves. His opponents will not change their minds to his way of thinking, which means that what Thorek is actually advocating is essentially a purge of the runesmith's guild. Likely with a bunch of the more prominent anti-Dum runelords being forced to take the Slayer's oath, while others are essentially forces to become hermits, staying out of the limelight and becoming increasingly marginalized. Unfortunately this will probably deprive the KA of their work, and might actually precipitate another major loss of runelore as the Runelords that die take their age-old secrets to the grave with them. An argument could be made that the runesmith's guild would be better off in the very long run, but there's little doubt in my mind that this would cause a large decrease in the Karaz Ankor's capabilities in the short to medium term (I.E. within this quest).
And finally, this would tie out ship to Thorek's as far as runemith politics goes. We'd have a definate ally in him and his faction, but at the cost of alienating his enemies. And not just because he's using our words as his rallying cry - and plenty will likely guess we did it at his request - but also because his actions will increasingly politicize the runesmith's guild. And that increasing politicization will occur right as we work closely with one of the faction leaders. Something that could potentially get us into all sorts of trouble even if he wins... And if Thorek loses we - and whoever we drag into the project - also lose big. Potentially grudge-worthy big if the Thorek's loss means the consensus becomes that shareing runelore on waystones is bad, and has to be prevented.
All in all, I think we need Thorek's help here, which means we need to accept one of these prices. And while I find it distasteful, I think pressuring the imperial dwarves will turn out less bad that giving Thorek cause to tear the guild asunder. That last one is too risky, and would too diminish the dwarves at a time when their resurgence is really getting rolling. So I'm planning on
