Two fanfic authors could not divide the fictional universe and went to court

History of water and land" For the first time in the history of English-language fan literature (fan-fiction, fan-fic, or fanfic), a dispute between two authors about the right to use tropes and motifs common to the original universe, or the fictional world, according to whose laws works of this genre are created, will be resolved in US federal court.
