Matters or doesn’t matter?No, I got it, I just think a genuine difference in metaphysical basis actually matters except in cases where everyone involved is confused about where their esoteric nature comes from, and that doesn't seem to be Nephiliim (they might not be sure of some details of the source, but they know its a common source).
I don’t think superpowers origins matter unless it’s used as a plot point in adventures, particularly if characters use a universal set of rules to represent their powers regardless of origin.
Vampires and wizards are going to have different social concerns, regardless of the fine details. E.g. Wizards aren’t going to worry about finding victims unless they’re blood wizards.
E.g. Nephilim’s equivalents of vampires and wizards may share the same origin, but they have significantly different capabilities and social concerns.
