But I can think of a dozen other scenarios. A doppelganger has been running around impersonating nobility and then assassinating whoever gives them audience. You're on a different plane of existence, a different timeline, an alternate universe. Even if your world has divinely chosen nobles, does that apply to every noble? Including the example of successful businessman given a title? What if that title is granted halfway around the world in a region the locals have never hear of? These are all things that could happen in my campaign.
