Firstly, expressing interest (and I'm even already almost done with a character sheet).
Second, Draconilian, wyverns can be defined as just a type/variety of dragon. The only difference is the lack of forelegs, as they are replaced by the wings (rather like birds). The definition of dragon is hugely different in different areas of our world, let alone Nirn. Maybe there are other dragons that look Chinese and Japanese, and Skyrim's are only one variety?
