Overlapping Elements and Blurred Lines

Despite their distinct characteristics, science fiction and fantasy often blur the lines between genres, resulting in works that incorporate elements from both. One such example is the subgenre known as science fantasy. In science fantasy, authors combine scientific principles and advancements with magical or supernatural elements, creating unique and imaginative worlds that defy categorization.

Blending genres can offer writers and readers a fresh and exciting perspective by combining the best of both worlds.
