Journey into Darkness : An Unauthorized History of Kane Journey into Darkness ( ISBN 1 - 4165 - 0747 - 7 ) is a 2005 novel written by Michael Chiappetta and David Stern and published by Pocket Books for World Wrestling Entertainment . The book is a fictionalized history of the professional wrestling character Kane , portrayed by Glenn Jacobs . The story ties together pieces of the real life Glenn Jacobs with Kane , such as giving the character the name Glen Jacob Callaway , and the idea that he took the name ' Kane ' from his mother ' s maiden name , as she was referred to several times as ' Suzanna Kane ' . The story also deals very sparingly with the character of The Undertaker , Kane ' s storyline brother . This was the first WWE fiction novel , the second being " Big Apple Take Down " . Continuity . The Callaway name is spelled with two L ' s in the book , which runs contrary to the spelling of Mark Calaway ( the wrestler who portrays The Undertaker ) , as established by the caption to a high school yearbook photograph and his father ' s obituary . This may have been done for the purposes of kayfabe , as Jacobs , who portrays Kane , is not legitimately related to Mark Calaway , and both the Undertaker and Kane themselves are fictional characters . The alteration of the Undertaker ' s real life last name in the book is therefore understandable as a mixture of real life and the fictional history which involves both Kane and The Undertaker , as well as Paul Bearer . In addition , Glenn is spelled with only one " n " in the book . Many sites incorrectly spell Glenn Jacobs as Glen Jacobs , possibly because of this . Kane spent time over in Spain learning his craft . Jacobs was born in Madrid , Spain , perhaps explaining why this place was chosen . It also goes on to state that Kane is the victim of a rare disorder called " Hereditary Sensory and Autonomic Neuropathy " . This meant that Kane was incapable of feeling anything , but could still feel other sensations through touch . It also attempts to explain how Katie Vick came into contact with Kane — a " massive " continuity gaffe at the time the storyline was introduced . The book also interweaves Gene Snitsky , with whom Kane had been feuding in late 2004 and early 2005 , into Kane ' s past . Loose ends . The story deals very little with some of the much larger components of the Kane character , such as how and when he gained powers similar to The Undertaker ' s powers . It also does not explain where The Undertaker gained his powers either . This in itself is a continuity gaffe because the Undertaker character has been supposedly capable of mystical feats , which Kane was supposedly capable of matching . The two characters are supposedly able to teleport and had various other powers , which included shooting fireballs and summoning bolts of lightning . It also does not explain why Kane seemed to suddenly lose his inability to feel pain and then partially regain it . Also , it mentions that the fire happened on November 7 , but on an episode of " RAW " , the official date was May 19 . As May 19 was the release date of the film " See No Evil " , this changing of the date of the fire is probably a retcon , as the date also became part of an aborted storyline in which Kane battled someone supposedly from Kane ' s past who had begun impersonating him . It is also the date his parents died . It also does not explain why the parents of the Undertaker ( his mother being Kane ' s blood relative ) were buried on Long Island , New York , rather than in Texas where the two characters were supposedly born and for the most part , grew up ( Mark Calaway is a Texas native in real life ) . However the book does detail the backstory of Kane with a partial filling of some , though not nearly all , of the larger plotholes behind the character introduced after the events of the Katie Vick angle , and the subsequent unmasking of Kane . The one thing it does explain is the exact reason why the Callaways died in the fire which supposedly scarred Kane . This does more or less confirm comments and assertions by the Undertaker that he had set the fire , but his reasons for doing it were entirely skewed , apparently for the purpose of causing emotional harm to Kane himself later on in WWE storylines , but this little tidbit does dispel some theories that Paul Bearer had somehow brainwashed The Undertaker into saying that he had set the fire . ( Though the book makes vague allusions to the idea that Paul Bearer MAY have in fact somehow brainwashed the Undertaker prior to the events of WWE ' s " Judgment Day " even in October 1998 , in which the Ministry of Darkness storyline began , explaining his sudden heel turn . ) It does however , completely invalidate the earlier story The Undertaker had told about the events of the fire . So the book at the same time upholds and yet debunks certain parts of existing WWE canon . Specifically , the changes made to the canon state that what happened was a complete accident , and that Undertaker had fled the house in fear . In previous WWE canon established from the days of the Ministry of Darkness storyline , Undertaker still asserts to having set the fire , but claimed originally to have done it because Kane was ' Weak as a child just like [ Kane ] was weak now ' . Despite this Kane and the Undertaker later joined forces two years later , during which Undertaker still boasted about setting the fire , but also claimed a protectiveness of his family . The Undertaker & Kane were also friends back in High School .
