Noble titles in the Wold
From Woldipedia
Aisildur has nobility. That's the only one I know of (says Jerry).
PCity has knighthoods both for bravery in defense of the country as well as for doing something grand for the city that didn't involve war. It is not an inherited title
Floating City has no nobility that I know of. I think I remember them having "titles" like Overlord's Champion, Archmage to the Overlord, etc. Again, these are not inherited.
Hook City's nobles would be called "citizens" or "original citizens." If you're within the city, you are elite.
We could set some up if they were REALLY needed. I've never been big on all that. ;) Don't hate it, but just didn't want to fiddle with all the honorifics.
