The myriad people, stories and histories of Babylon 5 are held together in the digital mind of The Great Machine, a fan-created wiki dedicated to J. Michael Straczynski's science-fiction epic.

The site's records spawn all of the setting's incarnations, from the original Babylon 5 television series to the made-for-TV movies to its final swan songs Crusade and The Legend of the Rangers. Summaries are given of almost every episode and movie, as well as the series' important and secondary characters, significant places and notable events. Gamers will find a detailed history of the failed B5 space-combat sim Into the Fire, as well as a Mods section detailing B5-themed mods created for Civilization IV, Nexus: The Jupiter Incident, Freelancer and Freespace.

The write-ups number nearly 1,000 but tend to be less detailed than fan wikis for Star Trek and Star Wars. Fortunately, its open nature means that fans can easily add to The Great Machine's collective lore by adding, expanding or revising any of its entries.
