<P> Setting out to write something on an epic scale, Martin projected to write three books of 800 manuscript pages in the very early stages of the series . His original 1990s contract specified one - year deadlines for his previous literary works, but Martin only realized later that his new books were longer and hence required more writing time . In 2000, Martin planned to take 18 months to two years for each volume and projected the last of the planned six books to be released five or six years later . However, with the Ice and Fire series evolving into the biggest and most ambitious story he has ever attempted writing, he still has two more books to write as of 2016 . Martin said he needed to be in his own office in Santa Fe, New Mexico to immerse himself in the fictional world and write . As of 2011, Martin was still typing his fiction on a DOS computer with WordStar 4.0 software . He begins each day at 10 am with rewriting and polishing the previous day's work, and may write all day or struggle to write anything . Excised material and previous old versions are saved to be possibly re-inserted at a later time . </P> <P> Martin set the Ice and Fire story in a secondary world inspired by Tolkien's writing . Unlike Tolkien, who created entire languages, mythologies, and histories for Middle - earth long before writing The Lord of the Rings, Martin usually starts with a rough sketch of an imaginary world that he improvises into a workable fictional setting along the way . He described his writing as coming from a subconscious level in "almost a daydreaming process", and his stories, which have a mythic rather than a scientific core, draw from emotion instead of rationality . Martin employs maps and a cast list topping 60 pages in the fourth volume, but keeps most information in his mind . His imagined backstory remains subject to change until published, and only the novels count as canon . Martin does not intend to publish his private notes after the series is finished . </P> <P> Martin drew much inspiration from actual history for the series, having several bookcases filled with medieval history for research and visiting historic European landmarks . For an American who speaks only English, the history of England proved the easiest source of medieval history for him, giving the series a British rather than a German or Spanish historic flavor . For example, Ned and Robb Stark resemble Richard, 3rd Duke of York and his son Edward IV, and Queen Cersei resembles both Margaret of Anjou and Elizabeth Woodville . Martin immersed himself in many diverse medieval topics such as clothing, food, feasting, and tournaments, to have the facts at hand if needed during writing . The series was in particular influenced by the Hundred Years' War, the Crusades, the Albigensian Crusade, and the Wars of the Roses, although Martin refrained from making any direct adaptations . Martin was also inspired by the French historical novels The Accursed Kings by Maurice Druon, which are about the French monarchy in the 13th and 14th centuries . </P> <P> The story is written to follow principal landmarks with an ultimate destination, but leaves Martin room for improvisation . On occasion, improvised details significantly affected the planned story . By the fourth book, Martin kept more private notes than ever before to keep track of the many subplots, which became so detailed and sprawling by the fifth book as to be unwieldy . Martin's editors, copy editors, and readers monitor for accidental mistakes, although some errors have slipped into publication . For instance, Martin has inconsistently referred to certain characters' eye colors, and has described a horse as being of one sex and then another . </P>
