I think there should be a "den" staging area for wolves that guild members can put up wolves that they want to be freely taken by other guild members! Maybe it can start at 10 spots and be expanded with talent points?
That seems nice! A free wolf exchange mechanic seems cute, I can see use cases (especially for guilds that might be centered around a certain wolf aesthetic, or roleplay guilds with lore reasons for wolves to “travel” between dens, or just leveled up “battle” wolves for newbie players), and as suggested it seems realistically-scoped enough to work as a feature. Seconding!
