If you were given the chance to develop your very own Game of Thrones spin off, what would you want to see? For me, I'd love to see what the world would be like after jumping forward several hundred years, taking it up to our modern times. How might a world where dragons and White Walkers are real might develop after industrialisation, electricity and computers? How much would have become myth and legend? What great cities might've sprung up? What families are still around?
