Q:
Does a new name appear in the personal story?
No reason not to work that way. Stuff like this works as a template, not as a fixed text stored somewhere. So whenever you open the panel, it does something like “Pull out of the database and print StoryVar1, pull out of the database and print CharacterName, pull out of the database and print StoryVar2…”
20 level 80s and counting.
I just checked. It uses the post-change name.
