Sitting with the elders is something Snorri would do (and probably has been doing offscreen) for the last hundred years.
But i don't see him getting involved in things like negotiations on behalf of clan Winterheath. He's got enough on his plate with being the runelord of kraka drakk and his own work.
Due to (probably not reading closely enough) the way the posts went, I got the impression that people asked "Can we sit with the other elders on Kumenouht?" and others answered "No, because we don't do politics." That sent me blinking and confused. And then even your own post shortly after seemed like a confirmation of that to me. ><
After a second readthrough,
@soulcake is Snorri old enough yet to be an elder of his clan and if yes is there any reason we wouldn't be involved in determining clan affairs?
this reply was probably referring to the "any reason we wouldn't be involved in determining clan affairs?" half of the post when saying "We don't do politics." Woops.
... Anyway. My previous post of "Well, people probably have a different feel for what counts as 'politics' and 'meddling' or not..." still more or less stands. Just with less of me assuming "Wait, sitting with the other 800+ year old elders is something we don't do 'because politics'? Whaaaat?" like a derp.
Right, anyway. Snorri probably does some dealing and advising and trading and business. Heck, we know he purchases land, when he goes out and finds the Odd Places things. We also know that he spends a lot of time writing and exchanging papers and letters, with all sorts of craftsdwarfs and colleagues and peers. And of course he sends his Hearth Guard out to go and be helpful.
But he doesn't... quite... politic the way you'd normally define politicking.
He just looks at the world in terms of 'things that need doing' or 'people that need help' or 'beautiful things that need to be crafted' and 'mysteries and pinnacles of craftsdwarfship to uncover and reach' and 'Ancestors to honor.'
... Oh, right, there's another question/topic of politics, too. Political affiliation, at least. Namely, Runelord-type politics and stuff. There, Snorri probably doesn't do much politicking. And hence gets a reputation of "a Dwarf who is very odd to other Runesmiths but possessed of impeccable honor." At least he's not another Yorri, who apparently "was known to rabble-rouse for the heck of it."
Snorri really knew how to teach 'em, though. The deliberately-shortened Apprenticeship, which resulted in a Runelord who takes teaching damn seriously and thoroughly, may even have been calculated for precisely that effect; of cultivating in someone a talent for free/odd-thinking, creativity, a desire to master many specialties and crafts, and a commitment to Apprentices when he takes them. Weird and crazy to do something like that, to give somebody a 20-year Apprenticeship with the expectation/foreward-thinking of the effects it'll have on that Dwarf's own Apprenticeships, but... But, well, Master Yorri
is quite skilled and clever.
