invite people to live in your castle? That's right! You think Noster the beggar deserves a better life? Ask him to live there! You like that sexy waitress Hroki? Invite her too! Wanna collect NPC's you like into one area? No problem, just invite them to live there! have a kick-ass castle complete with it's own mines, hotsprings, soulgem forge, can hold 40+ followers, marketplace, arena, etc.
order anyone to empty their pockets and give their items to you? ask anyone, like maybe say, Farkas or Balgruuf's kids, to go out and patrol Skyrim as part of your elite rangers? have anyone you don't like beheaded? put to jail? enslaved?
