George R.R. Martin enlisted them in 2008 to assist with the project, which at the time he believed would be finished "in just a couple of years ." García is a Martin "superfan" whom the author and HBO have consulted on details previously established by Martin in the series . Addressing comparisons of The World of Ice & Fire to J.R.R. Tolkien's The Silmarillion, Martin clarified that while his book provides a basic overview of the many areas of his fictional world and their histories, he plans to someday publish a more extensive volume focusing primarily on the Targaryens, which he jokingly dubbed The GRRMarillion . As plans for an eventual second companion book became more solidified, Martin said that it would more formally be titled "Fire and Blood", because it gives expanded detail on the reign of each Targaryen king . </P>
