Wanted to take stock of common misconceptions people have about Typemoon stuff that you see that have or had spread due to popular fanfics, mistranslations, or because it was repeated so many times. Or things that people assume when there is no evidence for or against. Can include things that have been debunked.
As well as discussion on why this fanon spread and they make intuitive sense to the people who believe and defend them.

For instance off the top of my head
The World is a RM
There are only 5? RM users
King Hassan has MEoDP
Caliburn had the concept of "assured victory" so that's how it beat Herc

I think people really latched onto the MEoDP thing for King Hassan because of his blue fire-y eyes, his Insta-death gimmick, and the fact that he was Grand Assassin. And like MEoDP is literally the uber-tier killing power. So it makes sense that the greatest "killer" in history should have the greatest "killing" power. And the whole Tiamat thing about "giving her the concept of death." Which when you think about it, is explicitly like not how MEoDP works.
