This is a work of fiction. It is meant to entertain, not instruct. It is not intended as a work of theology and, if it were, would fail utterly, as much of it would be really bad theology. Again: it is meant to entertain, not instruct.
I have chosen to base this off of several other works of fiction, largely because mixing the ideas from Mrs. Rowling with those from these other works is amusing. At times these choices constrain other choices I as an author might have otherwise made differently. Some of the theology here-in is really bad theology not because I could not imagine better, but because I sourced it in. I cannot fix everything without destroying the crossover feel that I am aiming for. In particular, much of the information in this section comes from, or rather is based on, Many Waters, although what I came up with dovetails nicely (or at least I think it does) with a concept I get from The Screwtape Letters concerning the morphology of angelic beings.
Recall that these appendices are written from the perspective of an in-world researcher. These in-world researchers are off stage both in the that they do not appear in the story itself, but also in the sense that they are not necessarily from the present as the characters in the story would perceive time. Not all of these researchers have written in the same style, nor have all aimed at, or achieved, any uniform level of professional scholarly writing. Most of these researchers are religious figures working for various in-world Vatican departments or commissions.
Footnotes are not part of the in-world document, despite any appearance to the contrary, and despite the fact that if this were a real document, it would have been written with real footnotes.
A people punished primarily with changes to their magic, reproduction, and lifespan. The placement of veela on this list is highly controversial. In raw cognitive ability, a veela is roughly equivalent to a normal human. The problem is in her emotional intelligence. Many veela have essentially no control over their emotions, and this triggers the magic of her punishment. - See The Veela Curse for an in depth description. - Veela are also complex to categorize because the nature of the veela “curse” makes it difficult for researchers to distinguish between the so-called “full” and “partial” veela. - The veela is the only example of a “race” that is purely female, it depends on cross breeding to survive. Due to the nature of its magic, any female child is born veela. See The Veela Curse for more details.
