Fallout Bible 1 Fallout Bible 1 is the first installment of the " Fallout Bible " , a collection of documents containing background material for the first " Fallout " games compiled and written by Chris Avellone . This installment was released on January 15 , 2002 . All information from " Fallout Bible 1 " , " Fallout Bible 2 " , and " Fallout Bible 3 " was later revised and included in " Fallout Bible 0 " . Content . Disclaimers . Thanks for supporting Fallout , Chris Avellone down here at Black Isle Studios What ' s in this section . Anyway , so this submission is going to include the following : Answer me these questions three . Three huge questions courtesy of Sean McGrorey : 1 . Why was it that so many ghoul s left necropolis between Fallout 1 and 2 to settle in Broken Hills and Gecko ? Is necropolis empty now ? Also , why was it that Harold joined the ghouls ? I remember him talking as if he weren ' t a ghoul ; When you type in " ghouls " in the question box in the first Fallout he refers to the ghouls as " them " . Answer : 2 . Does FEV really cause sterility ? In Fallout 1 it seemed like the answer was a resounding yes , and a number of reasons for this were given by Zax and Vree . But then in Fallout 2 after you take Marcus to the Cat ' s Paw he says " I hope she doesn ' t get pregnant " and says that the FEV doesn ' t make mutants go sterile , it just makes it take a few years " to get the juices flowing again " . Moreoever , the deathclaw s in Vault 13 were infected with FEV and yet they are able to reproduce . So , does the FEV cause sterility or not ? Answer : 3 . Are the radscorpions a product of the FEV virus ? When you talk to the doctor , Razlo , in Shady Sands , he tells you that they were once American Emperor Scorpions but that he has no idea how they mutated because radiation alone couldn ' t have done it . For that matter , what about all of the other creatures of the wasteland ? Which ones have been mutated by FEV and which ones haven ' t ? Maybe in the bestiary each creature could have a stat that shows it ' s level of FEV infection . Answer : Glossary . Vault - Tec is used two different ways in Fallout 1 and Fallout 2 . The correct version is " Vault - Tec . " Behind the scenes . In case you guys were ever curious , the man behind the spoken ( voice - acted ) dialogue in Fallout 1 and Fallout 2 was Mark O ' Green , the former head of Interplay ' s Dragonplay division ( our old D & D division before it became Black Isle ) . He ' s got a good way with words . Vault System . It was intended that while the player was reading the Vault 8 records in Fallout 2 , he could discover a classified file ( opened with a successful Science skill roll ) which explained that Vault 8 was a " control Vault , " designed to hold 1000 people and to open on time . This file was intended to foreshadow the discovery of the true and sinister purpose of the Vaults . The player was also intended to apply his Science skill to the central computer in Vault 13 to obtain a history of Vault 13 , the Overseer ' s involvement in the Vault Dweller ' s expulsion , and even worse , the true purposes of the Vaults . The Overseer was conscious of the true purpose of the Vaults as social experiments on a grand scale , and he drove out the Vault Dweller because he was afraid that he would ruin the experiment . . . or uncover it . Of course , the Overseer himself caused problems not long after this , according to Martin Frobisher , the leader of Vault 13 in Fallout 2 : Martin did not see the Overseer executed , however . . . his information comes from the Vault 13 records passed down by his ancestors . Basically , the Vaults were never intended to save the population of the United States . With a population of almost 400 million by 2077 , the U . S . would need nearly 400 , 000 Vaults the size of Vault 13 , and Vault - Tec was commissioned to build only 122 such Vaults . The real reason for these Vaults was to study pre - selected segments of the population to see how they react to the stresses of isolationism and how successfully they re - colonize after the Vault opens . Some of the experiments include : Rumor has it there were 122 different vault experiments . For Fan Fiction purposes , a lot of these vault experiments have been left open for you to play around with . Fallout Timeline table , first draft . The following timeline information was compiled from information I was able to dig up in Fallout 1 and Fallout 2 , as well as some old Word documents lying around . Considering how much has been lost in the years since the bombs dropped , keeping an accurate timeline is difficult , so there is bound to be some inconsistencies . This is considered a first draft , because revisions to this timeline are likely to occur based on feedback from you guys , and feedback is welcome - trying to sift through history is proving to be pretty difficult . : ) I couldn ' t verify certain information on ZAX , the BOS history holodisk , and various logs from the Master , because I ' ve lost my Fallout 1 save games . If anyone has screenshots of these things they ' d like to share , I ' d be grateful . It ' d take me a few days to play back to those spots . Once I get these , I can do another revision of the timeline , since I ' m not exactly sure of the chronology for the BOS and Master . Here is what can be recovered from the records that exist :
