Just sticking my beak in as the Charodaen creator.
Charoda are bloody weird things to play, particularly in a world like Mizahar. There's all sorts of things under the sea that are particularly dangerous, and they have their way of handling them.
Charbosi really needs to be developed, because their hometown is really closed off to others.
I think, though, when I get the city developed, more people will have interest in them for play.
But yes... the avatar/playby is probably the hardest part of them. >.>
