"Most magical creatures have ancestry to fey. Some closer than others. In any event, I generally know if someone has magical creature blood. Kind of like how you can feel magic near you, depending on how attuned you are to magic. Though it gets harder the higher the fey hierarchy. Fewer and fewer differences essentially." That was why I couldn’t necessarily tell what Luna was. She had ancestry from a fey, that I could tell. Just no idea what type of fey.
