I know that sound weird. but hear me out. I was standing on my Alinor terrace when I thought, hmm, sure would be nice to have someone here playing the lute and singing. And maybe have some people dancing and laughing to make this place feel lively.
And then I thought, oh would be nice to have one of those cooks too. and maybe some people cavorting in the dining hall.
So yeah, I think it would be really cool if we could buy just generic looking npc's to have in our homes that would operate the way they do in npc homes or in public buildings. That would be really cool imo.
