Spike is a comic book series published by IDW Publishing.
 Written by Brian Lynch, it focuses on the character of Spike, a main character in television series "Buffy the Vampire Slayer" and its spin-off, "Angel".
 Uniquely, although this is a spin-off from IDW's larger , it also serves as a prequel to Dark Horse Comics' own "Buffy the Vampire Slayer Season Eight" comic book series.
 As such, it is "canon" to the overall "Buffyverse" in which stories take place.
 Although originally intended as an ongoing series, the "Angel" rights transfer from IDW to Dark Horse caused the series end after eight issues.
Unisystem is a generic role-playing game system produced by Eden Studios, Inc. It is used in "All Flesh Must Be Eaten", the Buffyverse role-playing games, "CJ Carella's WitchCraft", "Conspiracy X (2nd Ed.)
", and several other games.
 Games designed using "Unisystem" have been nominated for, and won, Origins Awards.
Faith is a fictional character created by Joss Whedon for the television series "Buffy the Vampire Slayer".
 Played by actress Eliza Dushku, Faith was introduced in the third season of "Buffy" and was a focus of that season's overarching plot.
 She returned for shorter story arcs on "Buffy" and its spin-off, "Angel".
 The character's story is continued in the comic book series "Buffy the Vampire Slayer Season Eight", and she also appears in apocryphal material such as other comic books and novels.
 Faith was set to receive her own spin-off television series after the final season of "Buffy", but Eliza Dushku declined the offer, and the series was never made.
 The character later co-stars in the 25-issue comic book "Angel & Faith" beginning in August 2011 under the banner of "Buffy the Vampire Slayer Season Nine", the story taking place mostly in London and the surrounding area.
 Seven years after the character's creation, Whedon granted her the surname Lehane for a role-playing game and subsequent material.
 The last issue of "Season Eight" was the first source officially confirmed to be canon that referred to Faith by her full name.
The Buffy the Vampire Slayer Roleplaying Game is a role-playing game published by Eden Studios, Inc. in 2002.
The Buffyverse role-playing games - the "Buffy the Vampire Slayer" and "Angel" role-playing games - are complementary, officially licensed role-playing games (RPGs) published by Eden Studios, Inc. The "Buffy the Vampire Slayer Core Rulebook" was published in 2002, while the "Angel Corebook" followed in 2003.
 Both games use a streamlined (or "Cinematic") version of Eden Studios' popular "Unisystem" game engine, also featured in "CJ Carella's WitchCraft" and "All Flesh Must Be Eaten", two of Eden's better-known original product lines.
 In both games, players are able to take on the roles of characters from the respective television series or create wholly original characters as they and their group see fit, effectively building their own Buffyverse series in the process.
Buffy the Vampire Slayer is an American franchise which spans several media and genres.
 It began in 1992 with the film "Buffy the Vampire Slayer", written by Joss Whedon and directed by Fran Rubel Kuzui, and was resurrected as the television series, "Buffy the Vampire Slayer" in 1997.
 The show's popularity caused it to spawn a multitude of Expanded Universe tie-in material such as comic books, novels, and video games, as well as a spin-off program entitled "Angel".
 In 2007, four years after the television series' seventh and final season, "Buffy the Vampire Slayer" was officially continued in the comic book "Season Eight".
 The following is a list of minor recurring characters who appear in the franchise.
Eden Studios, Inc. is an American role-playing game publisher founded in 1996 by George Vasilakos, M. Alexander Jurkat, and Ed Healy.
 Currently run by Mr. Vasilakos, Eden Studios is best known for "Conspiracy X", the "Buffyverse role-playing games", "All Flesh Must Be Eaten", "CJ Carella's WitchCraft" and most recently for the "City of Heroes Roleplaying Game", an unreleased adaptation of Cryptic Studios' MMORPG "City of Heroes".
Angel is a fictional character created by Joss Whedon and David Greenwalt for the American television programs "Buffy the Vampire Slayer" and its spin-off series "Angel".
 The character is portrayed by actor David Boreanaz.
 As introduced in "Buffy" in 1997, Angel is a love interest for heroine Buffy Summers (Sarah Michelle Gellar), a young woman whose destiny as "the Slayer" is to fight the forces of evil, such as vampires and demons.
 However, their relationship is complicated by the fact that Angel is himself a vampire cursed with remorse and a human soul, which motivates him to assist Buffy in her duties as Slayer.
 The character's popularity led to the production of the spin-off "Angel", which follows the character's struggle towards redemption after moving to Los Angeles.
 In addition to the two television series, the character appears in the comic book continuations of both series, as well as much other expanded universe literature.
 Angel appears in the most television episodes of all the characters of both "Buffy the Vampire Slayer" and "Angel", appearing in 167 episodes (57 in "Buffy" and all 110 in "Angel").
Drusilla, or Dru, is a fictional character created by Joss Whedon and David Greenwalt for the American television series, "Buffy the Vampire Slayer" and "Angel".
 The character is portrayed by American actress Juliet Landau.
 Drusilla is introduced alongside her lover Spike (James Marsters) in the second season of "Buffy the Vampire Slayer" to serve as new antagonists to the series' heroine, vampire Slayer Buffy Summers (Sarah Michelle Gellar) and alongside Darla (Julie Benz) and Wolfram & Hart as the main antagonist of the second season of Angel.
 In contrast to the series' previous central villain, the ancient and ceremonious Master (Mark Metcalf), Spike and Dru were introduced as a more unconventional but equally dangerous pair of vampires.
Buffy Anne Summers is the titular character from the "Buffy the Vampire Slayer" franchise.
 She first appeared in the 1992 film "Buffy the Vampire Slayer" before going on to appear in the television series and subsequent comic book of the same name.
 The character has also appeared in the spin-off series "Angel", as well as numerous non-canon expanded universe material, such as novels, comics, and video games.
 Buffy was portrayed by Kristy Swanson in the film, and later by Sarah Michelle Gellar in the television series.
 Giselle Loren has lent her voice to the character in both the "Buffy" video games and an unproduced animated series, while Kelly Albanese lent her voice to the character in the "Buffy the Vampire Slayer Season Eight" motion comics.
