La Leyenda del Diablo del Municipio Sivellaus emerges as a cursed tome whose discovery in a violent crime scene in Volume 2 marks the first tangible link between the Sivellaus region and the supernatural. The book’s presence at the scene immediately signals that the legend is more than folklore, hinting at a sealed entity whose influence leaks into reality whenever the volume is disturbed. Across the series, the legend evolves from a local superstition into a recurring motif that foreshadows escalating demonic incursions, transforming the innocuous-looking book into a harbinger of larger metaphysical threats.
