here is how he came up with those stories: "well golly gee i wonder what it would be like if the story of Star Wars took place in Middle-earth, except that i'd call it Alagaesia . Also, what if the Jedi were the Dragonriders of Pern instead. And what if i called the Sith the Foresworn. And what if instead of lightsabers they had glowing swords. What if also, the magic system works the same way as it did in Earthsea. yea... yea that would be sweet, and i'd call it the 'Inheritance Trilogy', except then i'd change my mind and make 4 books." come on, now.
