2002年, Chris Avellone started putting out on a semi-regular basis what he called a Fallout Bible. The idea, initially elaborated by community veteran Dan Wood, was to create a document that would serve as a total guide to Fallout: the history of the setting, the elements that compose it, the things that define it and the rules that guide it. It would also serve to tie off loose ends left by the games and to generally do some clearing up of things. It was certainly a good idea, especially as the prospect of someone who wasn't Black Isle making Fallout games grew ever more real. However, it really didn't work out that way.
Instead of being a definitive, unambiguous guide to Fallout, Avellone's FOB became a sort of long question and answer session with fans emailing reams of queries to him and getting answers. Avellone would also usually toss in interesting bits of information about the games and original design documents, including the official Fallout timeline. Avellone made some mistakes here, many of which were corrected in later issues of the Bible thanks to fan feedback. The whole project was cut short when Avellone had to leave Black Isle.
There were 9 main installments of the Fallout Bible and Fallout Bible 0, a compilation of the first 3, including various corrections.
