Aww ty! I guess I have some random lore bits of them, sure ^^
I put Percy as fae originally, but he's a nymph! He was born out of the land itself, and belongs to it. One of the reasons he's so restless is that he has a subconscious compulsion to go back home. Percy will always find his way back to the Neverseas Islands, the forests part and twist to help him, and even the sea plays with him. It's all subtle enough you'd have to pay attention to even notice. He in, conversely, "clumsier" in RSA since he's away from home for a while. The longer he's away, the weaker his magic gets, and if he were to leave for too long his health would actually get worse too.
Also, a human Yuu could put 1 + 1 together and see what legends Percy has in their home world- like the Far Darrig.
It's very lucky for Tink that Jude hasn't yet correlated him with the troublemaking, impulsive runaway fairy that broke the Blue Moon, aka the fairies' main method of mass collecting fairy dust. The same fairy dust the kind fairies so generously gave Jude to help him transition and perform magic and he feels seriously indebted to the fairies for since it's become such a rare resource. And therefore has a serious grudge against the aforementioned troublemaker fairy.
Jude has a very boyish laugh! Snorts too! But the only ones to really make him laugh from his belly so far have been Percy and Gwen.
Typho considers Malleus a bro! He even helped the prince find some lost egg-shapped little console with a virtual pet inside.
Typho's whole family are a type of dragons from the Neverseas! There's less and less of them lately, they're nomadic, and they mostly avoid humans, so RSA is a real change for him. Their magic abilities are slightly different from the royal dragons, and weaker, but Typho doesn't rlly care. Female dragons have been specially elusive and so get preferred treatment here and there, but thankfully none of his dads took it to heart when Typho decided to transition.
Not really afraid of anything, but more cautious around petrifaction spells. They're no joke! (Slight childhood trauma of seeing his family petrified)
Ximmer's real form is, like Bibi, more insectiod! Most people find it off-putting so for RSA they take potions to look more humanoid.
Friends with Bibi. It started as business, going to buy supplies for adventures and classes, but they ended bonding over being insectoid-fairies and the troubles of it. Bibi feels out of place amidst beefolk or fairies, and Ximmer doesn't even know where they come from since the dragons adopted them as a baby.
Ximmer has a fixation for butterflies. Loves them and likes eating them, like some people with cows or chickens. Has since learned that humans don't find his eating habit too endearing.
