You are not stupid, Yavia. You offered it as an idea back then while we were brainstorming, please don't feel bad about it.
Living indoors can be applied to any of the tribes really, they all cuddle up and sleep somewhere, or have days where it's too cold or other weather conditions that are unwanted (like heat during draught in the desert). Wouldn't mind seeing some cosy Wolfrider dens, like when they're asleep, but you can still see the sun peaking in.
Actually, I can think of several situations for just the Wolfriders inside; like during a healing, or a cub being born, a sneaky hiding place during a game of Taal...
It is the situation we are in right now, true, but my introvert self doesn't see this as a bad thing of itself, and it's a fitting theme.
