Boy in Darkness is a novella written by Mervyn Peake.
 It was first published in 1956 by Eyre & Spottiswoode as part of the anthology "Sometime, Never: Three Tales of Imagination" (with other stories by William Golding and John Wyndham).
 A corrupt version of "Boy in Darkness" was published both in an anthology, "The Inner Landscape" (1969), and separately in 1976 with an introduction by Peake's widow, Maeve Gilmore.
 Referring to the corrupt text, she wrote that "although the Boy in "Boy in Darkness" is assuredly Titus Groan, [Peake] did not call him so by name"; however, adding the name Titus was one of the specific changes that Peake made between writing and publishing his novella.
 The correct text has recently become available again in an anthology entitled "Boy in Darkness and Other Stories", with a foreword by Joanne Harris and a preface by Peake's son Sebastian, as well as Maeve Gilmore's uncorrected introduction from 1976.

 "Angel: After the Fall" sees the heroic vampire, Angel, coping with the apocalyptic aftermath of the television series after he took over and subsequently betrayed the demonic law firm, Wolfram & Hart.
 The city of Los Angeles has since been sent to hell by Wolfram & Hart as a result of Angel's actions.
 The series follows his attempts to rescue the people he has sworn to protect.
 The first issue was released on November 21, 2007.
Engel (German for "angel" or "angels") is a role-playing game.
 The original German version uses a rule system in which the Gamemaster and players draw associative, tarot-like cards instead of rolling dice to determine the outcome of an event (this system is called the Arcana system in the original German version).
 The English version of "Engel" does not include the Arcana system at all; it is based on the d20 System instead.
 The German version includes d20 rules in addition to the Arcana system.
 The game was published by the German publisher Feder&Schwert (translates: "Feather&Sword"), who also published the World of Darkness RPG series in Germany and are now publishing the Dungeons & Dragons series.
