Fairy stories, also known as fairy tales, are popular stories that often feature magical creatures and supernatural elements. However, sometimes a darker or more realistic tone is desired in storytelling. In this case, antonyms for fairy story could include stories that are grim, macabre, gloomy, bleak, somber, or melancholy. These types of stories often contain horror, tragedy, or a sense of despair, and may not have a happy ending. Instead of magical creatures and fairy godmothers, they might feature monsters or villains. While fairy tales can provide an escape from reality, their opposite counterparts can explore the harsher aspects of human existence.
