@King Tai(I don't like using names that don't exist (or at least don't have some sort of real roots). The next thing I say is a bit of a spoiler, but eh... Admittedly, it's meant to be a surname for a family that's very existence is hidden in secrecy and not known to the public world (it's a clan of witches who are more or less the de facto leaders of all witches; think of them sort of like a "royalty" among witches), so I could get away with using a name that isn't real, but I'd still want it to have a legit meaning so it probably needs to be a real surname or at least be made up of real words... I'm pretty sure it meant "rose-something", but I've forgotten... There's a flower motif with a lot of the family members, so I went with that name. I picked the name several years ago...)
