Hey I would just like to say I'm pretty sure the skin color is off for like all of these characters that might be something you wanna look into and fix it's not ok to white wash but you know this happens sometimes so just try to fix that
That is the leader of Fang, quite easier to identify through her hair color actually. She is also the mother of Namaari, perhaps you should rewatch the show. Although I do agree that the creator did whitewash them a bit and make it a bit difficult to identify who is who.
I’m going to try and name most of the lands/country’s in Raya and the last dragon by memory Heart Fang Drill? (Probably something else) Tail? (At this point I’m just guessing)
