Ohhh! I have seen those meta/memes around before, and participated once myself in something adjacent with some Destiny characters - but no, that's not what I was referencing haha. It's rather charming to think of them defined as character directories, though... I guess in a way that's what they are? And I agree it's a useful exercise!

The directories I was referring to were more a table of contents for directing people to things about a character, usually an original creation who can't be otherwise Wiki'd.
