Ever so slight issue, people aren't gonna be writing this kind of information down for something like 9500-10000 QuestYears. To get it, we either need to get a good long look at an example of the architecture we want, and then we can make a similar structure, or if we want to get a general overview of proper castle construction techniques we would need to send a kid off to have an apprenticeship under a professional castle designer and then have them be the next person we play as, and get the data from him when we build stuff.
If you were to go a full season without having made anything, then he'd start getting a bit upset with you. However, once you've made enough weapons to arm every fighter in the valley, he won't really care all that much.
As long as you do it once a season, Dorri will be satisfied. Making quality stuff takes time, he knows that very well.
I suspect we can substitute Stored Experiences for this. This could be exceptionally helpful if we wanted to test this out on someone without offending them, or if we wanted to try it out on a Spirit who has already gone through this method before.
AFAIK, there is a shot at a piece of the Weapon in Vestifold, we may be able to nab it during that clusterfuck. There is also the option of mindblender, any way of permenantly fucking up their mind should effectively mission-kill them. Then there is the options of conceptual Destruction, which iirc is how Blackhand's Infinite Murder Fire works. A theoretical Death Hugariendia could do the trick, although I wouldn't trust it to work as they aren't killed by a lack of anything a normal human needs to live, and it may extend to them counting as dead for an attack that goes "If the target is alive, they are now dead". Etir would work, and I think the Nid hit from poisoning them would always be worth it. Odr poisoning to shatter their soul should also work, although getting the time for that would be hard. Maybe a Sedir to Needlebind open their Gate, and hope that we can keep them distracted long enough to have it kill them. Maybe Soulscape to Soulscape warfare, try and invade their soul with the spirits in our soul and if we win we can probably break their soul from inside? Maybe a teleport Burl that we throw at them, it shatters on them, and teleports them into the Gjoll (I think that one has lethal water?)
The way the stored Experience thing works is we focus all of our senses on the thing, to the exclusion of everything else, then spread the feeling of the missing sense over all the senses, and then we have the stored Experience. This mean we would need to go find another castle to do that to, as it only works with current stuff, not memories. Muna might work differently, but that would require testing.
