You opened up a bit of a tangent with this one, ahem hem
I drew my profile picture! She's my darling little wishdragon Rhubarb.


Wishdragons are somewhere between fairies and genies. They're the only dragons that are naturally Pirelic (i.e. bipedal) and otherwise don't really look like dragons, but they're affected by all the dragon magic and can hear the Call, so they must be dragons yeah?
They live in the half-awake kingdom of Tir na Nog, where they never want for anything. Rather than make them happy this bores them to tears since they've got nothing to do, and so they go on pilgrimages throughout Elysia and use their magic to grant wishes for less fortunate people (hence "wishdragon"). Slightly confusingly they call themselves "wishers" and their wish recipients "wishees".
Every wishdragon carries a little wish bible with them that tells them all the rules. It's in the wishdragon language that nobody else understands, and even if they did, every copy disappears if a non-wishdragon tries to take it.
Rhubarb in particular is extremely sweet and thoughtful, and has a great head to memorize the wish book, but she's often very clumsy with her magic, so Tir na Nog has... encouraged her to go on a pilgrimage. She's not exiled though, and over her adventures she gets better at the whole wishin' business.
One of the most important elements of wishin' is that a wishdragon is free to interpret and even muck a wish however she likes, as long as she acts towards a sincere belief of the wishee's best interests (i.e. the exact opposite of a leprechaun.) Thanks to her imagination and compassion, Rhubarb is extremely good at this... as long as she doesn't honestly screw up her magic.
