Question: Which independent publisher founded in 1993 by Jeffrey Thomas publishes horror, science-fiction, and dark fantasy?

full_context: Document 1: Definitions of science fiction: There have been many attempts at defining science fiction. This is a list of definitions that have been offered by authors, editors, critics and fans over the years since science fiction became a genre. Definitions of related terms such as "science fantasy", "speculative fiction", and "fabulation" are included where they are intended as definitions of aspects of science fiction or because they illuminate related definitions—see e.g. Robert Scholes's definitions of "fabulation" and "structural fabulation" below. Some definitions of sub-types of science fiction are included, too; for example see David Ketterer's definition of "philosophically-oriented science fiction". In addition, some definitions are included that define, for example, a science fiction story, rather than science fiction itself, since these also illuminate an underlying definition of science fiction.
Document 2: History of science fiction films: The history of science fiction films parallels that of the motion picture industry as a whole, although it took several decades before the genre was taken seriously. Since the 1960s, major science fiction films have succeeded in pulling in large audience shares, and films of this genre have become a regular staple of the film industry. Science fiction films have led the way in special effects technology, and have also been used as a vehicle for social commentary.
Document 3: Science fiction film: Science fiction film (or sci-fi) is a genre that uses speculative, fictional science-based depictions of phenomena that are not fully accepted by mainstream science, such as extraterrestrial lifeforms, alien worlds, extrasensory perception and time travel, along with futuristic elements such as spacecraft, robots, cyborgs, interstellar travel or other technologies. Science fiction films have often been used to focus on political or social issues, and to explore philosophical issues like the human condition. In many cases, tropes derived from written science fiction may be used by filmmakers ignorant of or at best indifferent to the standards of scientific plausibility and plot logic to which written science fiction is traditionally held.

Document 7: Science fiction: Science fiction (often shortened to SF or sci-fi) is a genre of speculative fiction, typically dealing with imaginative concepts such as futuristic science and technology, space travel, time travel, faster than light travel, parallel universes, and extraterrestrial life. Science fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas". It usually avoids the supernatural, and unlike the related genre of fantasy, historically, science-fiction stories were intended to have a grounding in science-based fact or theory at the time the story was created, but this connection is now limited to hard science fiction.
Document 8: 21st century in fiction: Many science fiction works have been set in the 21st century (years 2001 to 2100). With humanity now in the 21st century, many of the predictions of these works have so far been proven obsolete. This page lists only "predictions" regarding the 21st century, as opposed to contemporary accounts of the actual 21st century, which would be too numerous to list.
Document 9: Bizarro fiction: Bizarro fiction is a contemporary literary genre, which often uses elements of absurdism, satire, and the grotesque, along with pop-surrealism and genre fiction staples, in order to create subversive, weird, and entertaining works.

Much of its community revolves around Eraserhead Press, which is based in Portland, Oregon, and has hosted the BizarroCon yearly since 2008. The introduction to the first "Bizarro Starter Kit" describes Bizarro as "literature's equivalent to the cult section at the video store" and a genre that "strives not only to be strange, but fascinating, thought-provoking, and, above all, fun to read." According to Rose O'Keefe of Eraserhead Press: "Basically, if an audience enjoys a book or film primarily because of its weirdness, then it is Bizarro. Weirdness might not be the work's only appealing quality, but it is the major one."

Document 15: Utopian and dystopian fiction: The utopia and its derivative, the dystopia, are genres literature that explore social and political structures. Utopian fiction portrays a setting that agrees with the author's ethos, having various attributes of another reality intended to appeal to readers. Dystopian (or dystopic) fiction (sometimes combined with, but distinct from apocalyptic literature) is the opposite: the portrayal of a setting that completely disagrees with the author's ethos. Many novels combine both, often as a metaphor for the different directions humanity can take, depending on its choices, ending up with one of two possible futures. Both utopias and dystopias are commonly found in science fiction and other speculative fiction genres, and arguably are by definition a type of speculative fiction.
