The lines between science fiction and fantasy have been blurred considerably in the last few decades. Ever since "A Long Time Ago in a Galaxy Far, Far Away..." faded onto the big screen in 1977 with Star Wars, it's been a challenge to keep the genres separate. Aside from franchises created for film and television like Star Wars, this phenomenon has been shown in adaptations like The Expanse and The Wheel of Time. Both are set in their respective genres but use aspects of another as a means to elicit intrigue.
