Please answer the following question: Information:  - Ballantine Books is a major book publisher located in the United States, founded in 1952 by Ian Ballantine with his wife, Betty Ballantine.

The firm's early editors were Stanley Kauffman and Bernard Shir-Cliff.  - Fantasy is a fiction genre set in an imaginary universe, often but not always without any locations, events, or people from the real world. Most fantasy uses magic or other supernatural elements as a main plot element, theme, or setting. Magic and magical creatures are common in many of these imaginary worlds. Fantasy is generally distinguished from the genres of science fiction and horror by the expectation that it steers clear of scientific and macabre themes, respectively, though there is a great deal of overlap between the three, all of which are subgenres of speculative fiction.  - Del Rey Books is a branch of Ballantine Books, which is owned by Random House and, in turn, by Penguin Random House. It is a separate imprint established in 1977 under the editorship of author Lester del Rey and his wife Judy-Lynn del Rey. It specializes in science fiction and fantasy books, and formerly manga under its (now defunct) Del Rey Manga imprint. It publishes the "Star Wars" novels under the LucasBooks imprint (licensed from Lucasfilm, a subsidiary of The Walt Disney Studios division of The Walt Disney Company).  - The term "manga" (kanji: ; hiragana: ; katakana:  or ) in Japan is a word used to refer to both comics and cartooning.

It was formed as part of a cross-publishing relationship with Japanese publisher Kodansha. Some of the Del Rey titles, such as "Tsubasa Chronicle" and "xxxHolic", are published in the United Kingdom by Tanoshimi. Tricia Narwani, the editor of Del Rey, stated that "Del Rey finds most of its talent through conventions and existing professional contacts".  - Lester del Rey (June 2, 1915  May 10, 1993) was an American science fiction author and editor. He was the author of many books in the juvenile Winston Science Fiction series, and the editor at Del Rey Books, the fantasy and science fiction imprint of Ballantine Books, along with his fourth wife Judy-Lynn del Rey.  - The Silver Wolf is a novel by Alice Borchardt and published by Del Rey Books in 1993 .

She is perhaps best known for her popular and influential series of novels, "The Vampire Chronicles", revolving around the central character of Lestat. Books from "The Vampire Chronicles" were the subject of two film adaptations, "Interview with the Vampire" in 1994, and "Queen of the Damned" in 2002.  - Lucasfilm Ltd. LLC is an American film and television production company based in the Letterman Digital Arts Center in San Francisco, California. The studio is best known for creating and producing the "Star Wars" and "Indiana Jones" franchises, as well as its leadership in developing special effects, sound and computer animation for film.

The Walt Disney Company acquired Lucasfilm in 2012 at a valuation of $4.06 billion.  - The Walt Disney Company, commonly known as Disney, is an American diversified multinational mass media and entertainment conglomerate headquartered at the Walt Disney Studios in Burbank, California.

The company also operated under the names The Walt Disney Studio, then Walt Disney Productions. Taking on its current name in 1986, it expanded its existing operations and also started divisions focused upon theater, radio, music, publishing, and online media.  - Science fiction (often shortened to SF, sci-fi or scifi) 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.  - Random House is the largest general-interest paperback publisher in the world.
