[Opinions] Re: Azula and Sapphire
Azula is a beautiful name and I prefer it over Azure or other similar names which seem a little harsh and cold (which is ironic coming from the character this name originates from lol). And obviously I don't mind the association being an ATLA fan myself (I could also see Katara working in real life).
Sapphire has never worked for me as a name, if you want a quirky sounding gem name I think Topaz is a better choice.
