We have a bunch of categories. That's good.
They are totally disorganized. That's bad.
We need to have a proper category tree. A category tree is where we have one "base" category, and all other categories are "descendants" of it. So, something like this (for example):
This is important for making everything organized.
Also, there seem to currently be duplicate and unnecessary categories.
Category:Book_of_the_Dead_Item seems useless.
Thoughts? Feel free to propose a good tree (or part of one) in your posts.
