Just the basic framework is sufficient, thank you! I was curious about the general concepts, and you mentioned enough of the specific details to ward off any followup questions, I think.
I do have another question on a completely different subject, though!
Regarding beetle mounts for the Dwarves: What species of beetle do you see as the premium, most desired mounts, and which ones are more common, garden-variety? In Into the North, Atlas warbulls seem pretty valuable, but I was wondering if all beetles are rare and difficult to procure, forcing poorer dwarf clans to use big goats or boars; or if beetles are essentially the dwarven equivalent of horses, with different varieties and levels of quality?
