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.
