Fan fiction or fanfiction, also known as fan fic, fanfic, fic or FF, is fiction typically written in an amateur capacity by fans as a form of fan labor, unauthorized by, but based on, an existing work of fiction. The author uses copyrighted characters, settings, or other intellectual properties from the original creator(s) as a basis for their writing and can retain the original characters and settings, add their own, or both. Fan fiction ranges in length from a few sentences to novel-length and can be based on fictional and non-fictional media, including novels, movies, comics, television shows, musical groups, cartoons, anime and manga, and video games.

Dark fantasy fan fiction weaves together the eerie, the supernatural, and the heroic, creating stories that blend horror, myth, and magic. Inspired by three of my favorite TV series—Supernatural, Lucifer, and Wynonna Earp—these stories explore the battle between good and evil, the weight of destiny, and the personal struggles of those who walk the line between mortal and divine. Each show brings its own unique elements: Supernatural with its hunter legacy and angelic wars, Lucifer with its celestial dilemmas and devilish charm, and Wynonna Earp with its cursed lineage and demon-infested Wild West. This fan fiction is a tribute to these dark, thrilling worlds and the unforgettable characters who inhabit them.
