Mystic

Kind of like this setting's version of Marvel mutants in that they're humans who are a minority because of their powers/biology. In this specific case they gain powers related to magical creatures or magic human types like witches, but except for the latter almost always gain an appearance to match. Also some of them come from families that have had these powers for a long time, believing themselves descended from the actual magical beings (no one really knows), but they hid themselves behind inheritable illusions (meaning you were born with them on) until recently. Others have erupted seemingly spontaneously from non-mystic lines. Those that hid revealed themselves because their population was getting too big to keep covering up, but not before they got several governments to pass anti-hate legislation in secret. That last thing didn't sit well with conspiracy nuts, anti-magic religious nuts think they're demons, but there hasn't been a Marvel-esque hysteria (the kind with giant hunter robots) from most of the rest of humanity (not that there isn't prejudice).
