Oooh, as a potential side note, if we can steal any of that Skaven "Weird goop thing that is edible and can turn organic material into more of itself" stuff, we might be able to solve the food problem of this trip right then and there, and if any clan is likey to have plenty of that freaky biological miracle on hand it's probably Moulder.
It might not be easy to walk out of there with a full barrel, but if we can get a small container we can probably grow it into a more worthwhile size later.
After all, grass should count as organic, I think, and Kurgan territory at least has to have plenty of grass for their horses.
