A few thoughts on the Expedition's time of conclusion...
[ ] The job is done. Ale and riches for everybody.
This is insanely optimistic. The Karak doesn't have a reliable source of food, though planting of mushrooms is doubtless underway. It still doesn't have secure lines back to Barak Varr or to Karak Azul, though both are underway. It doesn't have a secure East Valley, as that's still under the eyes of greenskins. It still has no idea what dwells within and beneath a full half of the Karak's peaks. Declaring victory now is doing so from a position of weakness and ignorance on the blithely optimistic expectation that everything will continue to go well.
[ ] The Citadel should be destroyed before we can consider our position secure.
This is the absolute minimum we can consider.
[ ] The residents are weakened, taking the Citadel is now a possibility.
A far better choice; considering the mass of greenskin casualties and the tactical dominance of the Citadel over the Caldera. Letting the Expedition bleed a bit to storm the fortress now is likely to save far more blood over the coming years.
[ ] Taking Kvinn-Wyr would mean we have every Karag flanking the Eastern Valley.
This is true but I see no reason that we'd take Kvinn-Wyr over the Citadel when we know that it's full of trolls, who are unlikely to cause trouble on their own- they're more of an environmental hazard.
This... seems like what we need to do, if we're actually arguing for when the Expedition should end. Taking the Citadel will be nice, and it's important, but the Expedition has moved
very quickly. We have been visible to the greenskins and skaven here for what, a week at most? It could easily be taking that long for one of the major threats around there to be beating everyone else into line and gathering their forces.
We can't really leave until we have secured all the necessities needed to live here and a route back home- not merely planned on how to secure them, but
actually secured them- and thoroughly scouted our enemies, then eliminated any serious possibility of attack in the immediate future.
I'm very concerned that if we declare victory and thirty thousand humans go home, we'll be putting the people settling here in a position of slow, grinding attrition against the skaven and greenskins who live here. They'll do well, but they'll lose a dwarf or three at a time even though their enemies lose far more, and we know how that story goes. It's how Karaks die and get abandoned. We need to leave them not merely secure, but in a position of decisive superiority over all other forces in the Karak, such that even if they don't have enough population to actually live in the entire place they can at least be sure that they aren't being outbred and losing a war of attrition to enemies living in their own home.
I'm not sure how to express this sentiment in a short, punchy vote, though. For now I'll just go with this one.
