I have another question then.... Where does this lay?
So, if something so outstanding and typical of our world be questionable and uncertain upon virgin eyes looking at it, then why is a dragon only fantasy?
My answer, it has to do with the virgin eyes of the reader. How a writer cultivates their world, how they describe a creature or an event, the way they can put together words which allows two very different people to see a similar thing and KNOW it exists...or maybe, those two very different people see two completely different beings and KNOW the being exists SOMEWHERE.
Is it the creature which decides the genre'? No, I say, it is the reader...
