A True Dragon in GOT

A Dragon with the abilities of DND comes to the world of Westeros. With these abilities, this Dragon will shape the way the world is either for the better or for the worse. Though what this Dragon does is to be seen. This is a mixture of the Game of Thrones books and TV shows. As for which edition of DND I will be using, is the Fifth edition, but I will be adding homebrew things too. I do not own the book cover or GOT. — Description from novelcodex.org
