[x] Imperial Dispensation
No this is wrong. You are treating Emperor given dispension as less valid than Collage one and that is completely off base. Emperor says we are cool then we are cool. No if or buts about it. Nobody and I mean nobody in the Empire can go "but muh protocol" on Emperor given dispension. That is what being Emperor means.
You go Collage dispension, 50 people know about it. You take Emperor one, 3 people does. And Emperor one is more ironclad to booth.
No, i'm treating this on the idea that an enemy wanna be downtalking or is critical of the project for whatever reason.
And the head research found out about the fact you need Dhar in the waystones. And instead of letting all the different mage expert know about it, instead ignored protocol to go to the Emperor, who isn't a mage in order to by-pass every other expert's opinion.
Like, if you are a sigmariate, who's looking to shut down this project, this would be one easy place to press pressure at it, because like. Sigmaraties aren't stupid, if they find out you need Dhar to keep waystone functioning they'll probaly grumble, but they are also aware that the entire old world relies on them exisisting, you can't just go tearing them down, because they contain dark magic.
The fact that The grand theologan was willing to use the secret's of Dhar, proves that Sigmaraties are willing to comprimise on their beliefs if they think the situation deserves it.
So, you find out that waystones need Dhar, but that the head mage, instead of telling everyone about it, went out of her way in order to make sure that the least amount of people possible would find out. And, these people would be the patriacts, the supposely most trusted and loyal of all the mages to the Empire, and she didn't want them to know.
That more then anything, feels to me, like it would be way more suspicious. Because it's the actions of someone, that needs to hide stuff from their own side, because their own side might have objections to what your doing.
If we go through the proper protocols, we can point to them and go "We found out about the Dhar, and alereted everyone who needed to know, the most loyal and trustworthy of the mages to this at once", so there are checks and balances against Matilda going full dark lady mode over here, with Dhar waystones. While both would cause grumling amonst the Sigmar people, i think the one where we try to hide it, from our own members, is by far the more suspicious one
