The fact is that there is an incredulous amount of info in this wiki that will not be used (hear me out o.k)
An author can only write so much and the story in nearing the endgame,
It would not be very good if CK crammed a bunch of info into the story during
team runt going to the capital and dont even get me started on classes. sure the topic of classes would come up but even i know that there are to many to put into one journal entry. and if so it would be so boring readers would wanna gouge there eyes out.
In fact team runt will probably not go to most of the realms (possibly nether and/or ice-hollow) team runt will probably not use every potion team runt will probably not interact with most divinities (maybe servants though) team runt will probably not use every item. The truth is once an author finishes a series
They cant just hop on discord and say whoops actually max was evil and betrayed them all along so the majority of info will not be canon, An author only has power over there story through the books.
One of those "guide books" for example J.K Rowling released an official copy of fantastic beasts and where to find them ( with small notes in margins by harry)
I feel as if though that would probably be the the best option.
Thanks for reading through that wall of text.
TL;DR to much info not enough books if series ends without giving all info none of it will be canon
