I love the idea of creating a faction around crafting specifically, and designing their action economy and even hand size around that! Also seems like they're pretty peaceful!
Only thing I'm wondering about it with the manufactory, it seems like it could do something else really cool like maybe be a wild crafting piece, other than just being used for recruit. Also seems like if it's battled away, there isn't a way to put it back!
Really dig the faction!
