I have a some questions about my current avatar, mainly I just want to know what it is? There's a few avatars of this guy on the last page, it looks like some sort of dragon? Is it part of the lioden lore or is it just a random creepy figure?

Also, whenever I update my details and press save it says: "Your details have been saved.
However, your avatar was not saved as we couldn't find it." Why does it say that?
