Book of the War, an encyclopedia detailing the "War in Heaven" in the Faction Paradox spin-off stories. The Faction Paradox line was based on ideas created for BBC Books' line of Doctor Who novels, and contained many ideas and characters which had their roots in Doctor Who novels or television. However, many of these concepts were changed for legal and creative reasons — for example, the Time Lords became the "Great Houses". The Book of the War revealed that not only had the Great Houses deliberately altered Cwej's timeline and biodata, they were using alternate copies of him from different timelines as soldiers in their war with the mysterious "Enemy". These "Cwejen" existed in three types: the original (blond and handsome) "Cwej-Prime", the fat and balding Cwej-Plus, and the monstrous and heavily armored Cwej-Magnus. Each type existed in multiple iterations, which the Great Houses intended to use as an "Army of One." One of the Cwejen (implied to be the original) was present at a mysterious incident in the Hollywood Bowl, which may have been a point of contact with the Enemy. Chris does not appear by name in the subsequent Faction Paradox novels, but a character who strongly matches his description appears as an agent of the Great Houses in Lance Parkin's Warlords of Utopia. This individual calls himself "Herr Abschrift", German for "Mr. Copy", suggesting that he is one of the Cwejen, a suggestion that is strongly supported by the facts he is described as being a "perfect Aryan" (blond, blue eyed and physically fit), mentions working for something called "Mirraflex" (one of the Great Houses) and is fighting a Great War. Two of the Cwejen appear as slaves of a Timelord in the Bernice Summerfield audio, "The Adventure of the Diogenes Damsel". They had no knowledge of the original Chris Cwej, and vague knowledge of the Seventh Doctor as a mystical figure. Chris appeared as the protagonist in an anthology titled Cwej: Down the Middle, released in 2020 by Arcbeatle Press. The book also featured appearances by Iris Wildthyme. Prior to this release, he made an appearance in "Barnyard of the Cyberons", a short story featured in the novelization of Cyberon. Reception In Bookwyrm: An Unauthorized & Unconventional Guide to the Doctor Who Novels, Anthony Wilson and Robert Smith praise the introduction of Chris and Roz in Original Sin, saying that the characters are "set up marvellously
