Regarding those without magic, there are none, in terms of not having the ability to use magic, but there are those who just don't use it or who use it minimally. These people are not really looked at any differently since, again, magic is a natural thing. Just as someone who has trouble breathing isn't really [i]looked[/i] at differently, so to are those who don't use magic all too often. Still, one important distinction is that these people don't really have trouble using magic (as one may have trouble breathing), they just choose not to use it. Another thing to note is that in some way, shape or form, even these who don't use magic may still find themselves associating with some sort of magic, if following the premise that magic is a natural force, ever-present. See, in the realm, magic is persistent; one cannot really be non-magical in the realm, since non-magic isn't really a thing. Therefore, a coven would accept one who doesn't use magic just as they would one who does. But some people may question why someone would refrain from magic, and certain people would allow such a choice to affect their view on the person, but in general, its not that big of a deal - more of just a quirk.

Regarding phylacteries and life preservation, it is definitely plausible and theoretically possible, but OOCly, I don't think I'd want to allow a player and their character access to immortality. In practice, it just brings about the fear of over powered characters and et cetera. I don't even think that any of the enemies in this book will be using any techniques like this, candidly. Still, like some of the other specifics that have been discussed, I might be persuaded otherwise.
