Secondary World Fantasy refers to a genre of fiction that creates an entirely new universe, distinct from our own. This genre allows authors to construct intricate worlds with their own rules, cultures, and histories, often featuring elements like magic and mythical creatures. Notable examples include J.R.R. Tolkien's Middle-earth and C.S. Lewis's Narnia. In Secondary World Fantasy, the narrative often explores themes of heroism, adventure, and the struggle between good and evil. These richly imagined settings invite readers to escape reality and immerse themselves in fantastical realms, making it a beloved genre among fans of all ages.
