Okay, yeah. :/ That'd make things way complex for a short fic. I guess you could also have it that the higher castes breed for Blood affinity and tend to kill any lowblood who shows it so they're pretty rare and any higher jewels amongst them are as common as ... idk, a blueblood with helmsman-grade psychics... but yeah, even that much would make everything prety complex. Though I can see Aradia as pretty strong that way and confusing Equius even more. XDDD
