The Kraith stories are a well-known set of early Star Trek fan fiction. The earliest entries were written by Jacqueline Lichtenberg (best known for her later professionally-published Sime~Gen Universe novels) starting in 1969. These continuing through the first few years after the cancellation of the first Star Trek series. The stories are named after the kraith, a goblet or chalice used in the performance of certain Vulcan rituals which feature prominently in several of the stories.
