As soon the full lore is established, I will take it into consideration when making my Dark Knight, however, in the end I will shape my character as I see fit. I'm not one to break lore though, but it is important to know that there are several ways to be what a class/job is.
For example, the Marauders were ex-pirates, right? But just because you wield an axe doesn't mean you HAVE to be part of the Marauders. You could be self-taught or a travelling Marauder could teach you how to wield an axe.
The same with Dragoons. You don't HAVE to be an Elezen from Ishgard to be a Dragoon, your character could just as well have been taught in the ways of the Dragoon outside of Ishgard, which would explain how Miqo'te and Lalafel Dragoons exist.
It's the same with the Dark Knights. Yes, the ORIGINAL Dark Knights might be as the lore states, but that doesn't mean YOUR Dark Knight is one of them. It's an explanation to how the Dark Knights came to be, not a factual rule that ALL DARK KNIGHTS have to be one of those.
