The article explores the importance of the secondary world in Ursula K. Le Guinʼs Earthsea series, which evolved significantly over the more than thirty years she spent developing it. In her effort to introduce a new kind of fantasy heroine, Le Guin found it necessary to reshape the structure of her fictional world, focusing particularly on its historical background. She employed two main approaches to constructing this history, seen in A Description of Earthsea and Tales from Earthsea. The former adopts the tone and format of an official historical record, offering a comprehensive overview of the worldʼs development. Tales from Earthsea contrast with personal narratives set against the backdrop of major historical events. Tales from Earthsea is a notable feature of its emphasis on womenʼs perspectives, contributing to a more feminized view of history. The article concludes that by reimagining the history of Earthsea, Le Guin was able to thoughtfully reconstruct the seriesʼ world in a way that aligns with contemporary themes, while still maintaining the overarching philosophical principles of the original saga.
