Ok that is beyond my abilities to comprehend at the moment due to how f'ed it is.
and the fable system is just an example of how it wasn't implemented very well
Like it said it's like a half baked idea of mine so I wouldn't read much into it but....
It could work something like
Picking a character to start as in Final Fantasy XIV for example
you choose you deity or god you presumably worship, instead you could perhaps pick your heritage or family tree you wish to be born into, given the story line supports the reasoning behind it. There would be maybe idk 30-40 surnames to choose from.
Starting out this character in whichever heritage gains you a sort of
"temporary guild or Linkshell" and gives you people you can converse with prior to joining another Linkshell
many players don't usually find a linkshell immediately before they begin question and leveling so this could possibly add some more community aspect to the game that it might already be lacking
or maybe it doesn't
