I rather think it was conflicting experiments. Initially I followed the guide, then I added a character in-world, then I tried a whole lot of things before I set the character to be global, then I added a line for a new origin character in the Start goal, but nothing worked. So I reverted to before any attempts and started from scratch. Just adding the file under /CharacterCreation, adding a global character and a line to Start goal and it works.

So now I'm back on track!
